Mechanical Arrangement

SolidCore CoreXY Mechanical Arrangement

The mechanical arrangement of components such as motor and idler mounts, linear rails, carriage and gantry may or may not allow for add-ons such as an enclosure or heated chamber. For example, motor and idler mounts placed on the inside corners of the frame gives the needed clearance to mount an enclosure. Each design has it’s own advantages and disadvantages. The configuration above eliminates any design constraints of scalability so the overall length and width of the 3d printer build can be completely scalable.

HeVort-Advanced DIY 3D Printer

HeVort DIY 3D Printer: Non-Planer 3D Printing

The HeVort is a design that takes bed leveling to the next level. The Hevort 3-point bed tilt also changes the way parts need to be supported so for models with overhangs facing ‘uphill’ into the angle, supports aren’t needed. Although non-planar printing is not really widely implemented yet, there are new slicer post and processor components for printing at fixed angles other than 90. In the future, we may see more non-planar printing. This would allow you to print a part in vertical mode and add another component at an angle without need of support material or other mechanical aids.

With non-planar printing becoming more and more popular, it’s not surprising that slicer toolpaths are available. This means you can optimize how your layers are printed and reduce support needed thanks to angled orientation. One problem with 3D printing is that it can be difficult to support overhangs.

The HeVort uses a mechanical setup that consists of linear rails mounted to the bottom of the build plate along with 3-point bed leveling. It’s a concept called Non-planer 3d printing. Some refer to the setup as True Bed Leveling.

As slicer software advances, software will soon be able to generate optimized toolpaths for printing fixed angles. Combined with layer optimization, support material will no longer be needed.

CrazyCreatorCube Toolchanger

The CrazyCreatorCube Toolchanger was designed by Hendrik and Andy to develop a stable and efficient tool changer 3d printer. The main focus of this tool-changer project is to make a 3d printer tool changer with great 3d printing quality, easy maintenance, and cost efficiency.

E3D Tool Plate Compatible

The tool changinging 3d printer is 100% compatible with E3D tools and 99% of the CrazyCreatorCube parts can be found in stores or ordered online. Another goal of the 3d printer project is that the printer build should be possible for anyone with basic technical knowledge to build and assemble the CrazyCreatorCube.

Kinematic Bed System

The 350mm x 330mm bed or build plate uses a kinematic system to connect to the bed supports and the heated bed is moved along three axes and completely auto leveled.

Magnetic Tool-Changer

The magnetic ToolChanger uses a remote system which means the motor that rotates the safety bolt and holds the tool on the tool changer, sits on the frame and does not increase the weight of the print head.

Print-Head / Extruder

While a remote extruder is used in the classic CrazyCreatorCube version, a normal Direct drive extruder or Bowden extruder can also be used.

VORON 2.4

The Voron V2 by Voron Design is a well engineered printer with a very promising future. It has a huge community that loves their DIY builds and is very well documented.

Build volume: Scalable
Extruder: AfterBurner
Enclosure: Open or Enclosed
Moving Gantry
Electronics: Duet3D / Klipper

DESCRIPTION

The Voron V2.4 is a light weight and compact corexy motion system with a superior design. The printer has a moving gantry / fixed bed that utilizes four point z-axis belts which is very unique for a corexy. The design is easily enclosed and has a lighter moving mass which sets it up for high speed prints with beautiful parts. While the V2 is a great machine it’s probably not the best for first time builders but does have a build guide that some say is far superior.

Although the four Z-axis motors implementation and expansion board may be challenging for some there are many more builds much simpler to choose from that will produce great results. The Voron V2 has precision linear rails for the X- and Y-axes and dual-drive extruder. The design uses four independent z-axis stepper motors that are belt driven which eliminates z-wobble that most machines experience. The light-weight moving gantry design increases print quality with it’s belt driven system which makes this corexy 3d printer design a community favorite.

Blackbox Multi-Tool 3D Printer Toolchanger Platform

While there are many open source 3d printer designs available, most of them are limited to specific 3d printable plastics. The Blackbox was designed and created by Marc Schömann of Layershift.xyz, who has a different approach to 3d printing with multi-materials. The Blackbox is designed to be a flexible platform for multitool fabrication. The multitool / multimaterial manufacturing platform for printing highly exotic materials and integrated assemblies.

Water Cooled-Toolchanger

The Blackbox was designed to produce high-end parts that challenge most 3d printers. The Blackbox 3D printer is a fully open source design that uses water-cooled printheads and a direct drive toolchanging system. The water-cooled setup offers more precise thermal control that’s more reliable and consistent. These factors are the secret ingredient to high quality 3D printing.

Most common 3d printers are limited to printing single materials and colors. The blackbox has a different design goal. The Blackbox design aims to provide a machine that can produce high-end parts from a range of many different materials.

The Railcore uses 15mm frame extrusions and M3 hardware that brings down the cost. 15mm Extrusions use m3 hardware is much cheaper compared to m4 or m5 hardware. Although 15mm extrusions and m3 hardware may be less rigid the printer gains it’s rigidity from the reinforcement of the side panels. Many more design decisions were made to make the printer build as space efficient as possible while maximizing build volume. The printer build gains it’s rigidity

Complete CoreXY Kits vs Self-Sourced BOM Part Lists

While many designs are available in complete corexy kits, some open source 3d printer designs are currently still self-sourced, meaning that builders will have to source individual 3d printer parts and get it all together which results in complexity as some parts may take long to receive and increases the chance that one might order the wrong part number.

As more 3d printer mods and upgrades are increasingly announced in community groups and forums newly published designs that tend to be open-source and contributors announce their next printer designs such as anti-wobble lead screw nuts and belted z-axis drive mechanisms.

While some corexy designs are familiar to others it’s a great environment for the community as design options and functionality evolves. There’s more opportunity for designers and contributors to make their own mark or be the first to design their own unique versions of an idea from one printer applied to a newer 3d printer platform. Design concepts and unique features inspire the development of open-source 3d printers.

BEST COREXY 3D PRINTERS 2022

Cantilever Bed vs 3-point Bed Leveling

While many of the original corexy printers used cantilever beds, carriage wheels or smooth rod the newer and better corexy published designs are now using linear rails and have adopted more functional mechanisms such as belted z-axis, toolchangers and non-planar 3d printing concepts such as 3-point bed leveling or triple z with kinematic coupling bed mounts for tilting print beds for perfect bed leveling.

Although the simplicity of older corexy reprap printers were less technical and easier for newbies, the increasing number of options and features can easily be adopted from corexy design platform to another, which has exponentially inspired contributors as they work to identify or fix potential issues or increase overall print volume.

3D printer designs such as the HyperCube use a cantilevered bed lifting mechanism which is fine for what is now considered a smaller print bed size. For example, most earlier designs have 200mm print beds but newer 3d printer options are available with larger bed sizes as many 3d printer platforms average around 300mm x 300mm beds and increasingly push the limits of build volume to 500mm if not larger.

Heated Bed- DC vs Mains Powered Beds

While older corexy designs used DC-powered heat beds newer machine platforms are implementing mains-powered heat beds which allow users heat build plates much faster, however there’s nothing to stop you using a DC bed on a Voron or a mains bed on a HyperCube. It’s just wiring.

Build Volume- Scalability vs Reliability

While some designs scale up well beyond 300mm and other print volume sizes most 3d printer designs are offered in standard bed size options many people have moved away from the common 200mm bed size. Although, a smaller bed size reduces issues such as bed leveling and simplifies printer movement of a machine’s motion system movement.

BEST COREXY 3D PRINTERS 2022

Dual Z vs Triple Z

While earlier corexy 3d printers used the more common cantilever bed lifting mechanism which utilized a single stepper motor 3d printer with a dual Z axis lead screw setup mechanical layout which also worked well. However, there are plenty of Hypercube and D-Bot mods that implement dual-Z or linear rails or other components that increase accuracy and repeatability.

BEST COREXY 3D PRINTERS 2022

Thingiverse vs Github

There may be more mods available for the HyperCube and D-Bot style designs, but staying current with mods and other design alterations can be messy as previous users downloaded or contributed on platforms such as Thingiverse which is increasingly becoming more and more outdated due to inadequate search results and depreciating usability. Designers and contributors have migrated to platforms such as Github to download or share files which results in a much more organized approach that keeps the community up-to-date with design revisions.

Rods vs Linear Rails

Many of the earlier 3d printers were designed around cheaper mechanical parts such as carbon rods or stainless steel smooth rods which were once commonly used and recommended. As the cost of linear rails become cheaper and cheaper due to the economy of scale and increasing number of buyers and large volume production of manufactures and suppliers. 8mm steel rods and linear bearings are slowly being somewhat phased out but still used on cheap kits found on Aliexpress.

8-Bit vs 32-Bit Electronics

The 8-bit Marlin based boards such as the classic Ramps 1.4 have also been abandoned for more functional and customizable control boards and firmware that use 32-bit electronics with 24V Power Supplies and better stepper motor drivers like the Duet3d board. These control boards offer better documentation, support and large communities of technical users that share methods and firmware code to configure almost any 3d printer you could possibly design.

Customizability vs Availability

If you are looking for a cheap way to get started, building open source kits like the HyperCube and D-Bot is a good way to get started as you mod and upgrade your printer to a more functional machine. It’s much cheaper to build as you recycle or reuse parts like linear rods, lead screws and bearingsThe availability and access to mods miscellaneous parts with multiple design iterations.

Building a HyperCube or HEVO (Hypercube Evolution) can be quickly built which will get you started 3d printing as quick as a week spending on experience and mechanical knowledge some 3d printer designs can take months with the large number of parts and unfamiliar mechanical parts which may need more skill to assemble correctly. For example, corexy design options such as the Voron 3d printer can be a steep learning curve as one adventures off assembling the large number of 3d printed parts that may or may not fit together depending on how components were printed or choice of filament.

Layer Adhesion Layer and surface adhesion is a critical component of 3d printing. 3d printing issues increase as object size increases. Large 3d printers can be more difficult when it comes to bed leveling. As the extruded layers bond together they are fused with heat. Proper surface adhesion decreases warping that can decrease part quality.

SolidCore CoreXY Z-Axis Bed Leveling We recently started working on the SolidCore 3d printer‘s bed leveling and mounting system. The z-axis uses a 3-point kinematic bed mounting with magnetic pivot spheres on each mount This properly constrains the bed at 3 points of contact. The original SolidCore Z-axis design was somewhat primitive because we only

Loose belts are a common problem for users and cause a variety of issues. It may or may not be obvious that your 3d printer is experiencing issues. Belt tensioning defects can occur.

While there are many open source 3d printer designs to pick from on Thingiverse. And when it comes to corexy printer designs there are a few that raise the bar. Here are some of the best designs that we would like to talk about.

BigRep has been an industry leader in professional large scale 3d printers for a while now, and we had the chance to see their new machines at Rapid Event + TCT additive manufacturing convention. They showed off two of their printers they had on display: BigRep Studio and the even larger version, the BigRep One.

We first discovered RailCore Labs and their beautiful corexy design at MRRF 2019. The Railcore 3d printer was designed by designed by Tony Akens and J. Steve White when discussing an idea of a core xy printer with linear rails on the x,y and z-axis on Reprap IRC.

SolidCore CoreXY 3D Printer

While the SolidCore printer design is still a work in progress, the corexy build is slowly materializing. For now, we decided to go with a simple corexy design but have future plans for a toolchanger and a heated chamber. The design goal is to build a reliable high speed 3d printer with high quality aluminum parts for 3d printing high temperature materials such as PEEK.

Belt Path And Tensioning

If you want accurate motion, you need a CoreXY 3d printer design with straight and parallel belt paths. Belt tensioning can change when the belt length changes as the gantry moves. Otherwise racking or belt tensioning issues may occur. Belt segment that changes length must be parallel to the axis as it moves to avoid racking or other undesired motion that can occur. Belt thickness must be taken into account when laying out your pulleys. The belt sections between motor mounts and idler mounts need to be parallel with the axis as the gantry travels across.

SolidCore Carriage

Bowden vs Direct Drive

A Bowden setup will let you have higher acceleration but a direct drive extruder will give you higher feedrate. The difference in acceleration is in print time and can make a noticeable difference.

Direct drive gives you more control over the extruders and better print for flexible materials .
Bowden gives you a lightweight carriage design and is better for higher acceleration.

The moving mass from a direct drive extruder from the size or weight at higher print speeds. Reverberations that happen with fast accelerations and jerk rates. A heavier carriage also increases these artifacts. missing steps, that happen with fast accelerations and jerk rates and increases these artifacts.

Our long term goal is to is to build a modular platform, not just a printer. Think of it as an ecosystem of parts that can be arranged in different configurations and adapted for unique applications.

Build Volume – Scalability

SolidCore Carriage Belt Path

The SolidCore CoreXY design has the motor and idler parts assemble to the inside corners of the frame. This mechanical arrangement is better for adding an enclosure and scaling up the 3d printer size to a larger build area. Minimizing design constraints of overall 3d printer length and width makes the machine completely scalable and customizable.

Eventually we would like to have a spreadsheet or configuration tool that will allow you to input the current frame or linear rails that someone already owns and output length and rail options. Or if you’re aiming for a specific build area, you can input the data and it will output the frame and rail length options.

All Metal Parts

All Metal Parts Kit

The SolidCore aluminum parts makes the printer into a highspeed workhorse for repeated use. All-metal-parts and components will give us the durability and repeatablility needed. But we want people to have the option to use 3d printed parts so they can upgrade later on. Solid all metal parts are durable and less likely to deflect at high printing speeds. The aluminum components are also less likely to breakdown over time when introduced to the forces and heat from repeated use.

Carriage / Gantry

SolidCore CoreXY 3D Printer Carriage

The carriage and gantry are designed to be light weight and strong. We currently use c-shaped aluminum stock because it reduces machining time. The reduced machining time and minimized waste helps but it’s a compromise. That’s going to change soon. We’ll probably make some changes such as reorienting the the y-axis linear rail into a vertical position similar to the RailCore but the current horizontal version will be easier to adapt an E3D Toolchanger.

Metal X-Carriage Parts

The top plates or motor/belt mounting plates that mount the idler pulleys have recently changed as well. The motor/belt mounting plates shown position the z-axis motors on top vs the bottom of the machine. When I first designed the plates I thought it would look cool with the motors on top but after I machined everything I realized that moving the bed up and down could cause deflection in the main plates.

Motor Idler Plates

The left motor plates are going to be re-machined to give room for a tool changer setup.

The overall footprint of the machine relative to print volume is somewhat excessive. In order to have a solid enclosure design I had to move the motors inside the frame boundary. This sacrificed the overall printer size to print volume ratio.

We’re aiming to balance the pull to the center of carriage instead above it or below. It seems to be more rigid and minimize deflection. The belts are somewhat within the same plane of the three linear rails to avoid rocking cantilever loads that other designs may have with the belts up high or down low.

The original prototype was about 350mm x 350mm x 350mm print area but we now have a 200mm x 300mm and 400mm x 400mm build volume.

This design was inspired by the RailCore, HEVO, D-Bot, Mike Fisher’s QuadRod and Maarten van Lier’s corexy build.

Triple Z-Axis: Independent Driven or Shared Belt Routing

Z-Axis Single Stepper Motor Belt Routing

With the build plate removed the single z-axis stepper motor with shared belt routing is shown.

The SolidCore has two different z-axis designs to move the print bed. The SolidCore picture shown on this page has the z-axis motors at the top of frame.

Independent Driven Z-Axis Motors
Single Z-Axis Motor (Bottom)

Both z axis designs use 3-point bed leveling. The image below is of the prototype build which uses 12mm ball screw. The new design (yet to be shown) uses lead screw.

Three Point Kinematic Bed Mount

SolidCore CoreXY Z-Axis Bracket

Although the implementation of the kinematic bed coupling is till in progress, we are designing a mechanism that works for us. Three point bed leveling uses three independently driven lead screws to automatically level the bed and compensate for a bent bed plate or dips .The three z-axis lead screws are used as the three points that make up a triangle and define a plane. 3 points define a plain.

The advantage of a kinematic bed mount is that the defined plane of the bed can raise or lower without binding or twisting, keeping the bed flat. 3-points define a plane, therefore you will need to take into account the synchronization of the lead screws that raise and lower each point of the plane.

SolidCore CoreXY Z-Axis Bed Mount BracketsKinematic Coupling Bed Mounts

Build Plate

We’re using a mic6 tool plate for the bed. Cast Aluminum tool plate is a good solution because it has good thermal conductivity and heats up evenly without warp or twist. The bed needs to be flat and remain level. In three point bed leveling, the three z-axis lead screws are used as the three points that make up a triangle and define a plane.

Since 3 points define a plain 3 screws, evenly placed in a triangle will raise and lower that plain without imparting any twisting forces so the bed will stay flat. A mechanical bind can cause the bed to tilt over time. The advantage of a kinematic bed is that the aluminum plate can expand without causing anything to bend or flex.

Belt Layout

The corexy motion system uses crossed belts instead of offsetting the stepper motors giving the belt path a clean run. Simpily offsetting the motors may give a much better alignment path.

The belts don’t have to cross if the pulleys are at different z-levels, I always thought that was bv the difference between the hbot corexy was the corexy belts crossed at the m segment. But the difference between hbot and corexy is that hbot has a single belt on a single plane, corexy can have either 2 “non-intersecting planes” or a single plane + idlers on different levels to keep the belts from touching.

Hypercube for example doesn’t have that “x” because the belts are on different planes. The Railcore has the crossing belts but the belts are on different planes.

Motors at differing planes = straight belt paths
Motors at same plane = Crossing belts

DIY 3D Printer Core XY 310*310 mm

Hi Everyone.

As you know, there are unfortunately no perfect printers in China.

Prush-like drygosts are cheap, but slow at the same time.

Core XY - more interesting, but low-quality components are also used.

Therefore, I decided to assemble my own printer and immediately say is not for sale.

I just wanted to prove to myself that even a humanist is able to develop and assemble a good enough apparatus.

And he started his journey with the purchase of quality components:

In the Autodesk Inventor program, he developed his version of the printer completely from scratch.

And then he used the services of a company for cutting machine profiles.

With the help of corners 2040, I fastened the profiles together and, by the way, very reliably and evenly

Next I decided to assemble the table on profiles and corners, but in the end I will abandon this idea in favor of the finished version.

I installed the sfu1204 ballscrew and the table itself on 12mm linear shafts with flange bearings, while the motor uses two 48x, which will eventually be synchronized with each other.

I abandoned the idea with profiles on the table in favor of the usual corners 2040, they turned out to be more convenient for installing the table and at the same time quite rigid due to the rib

This decision fully justified itself.

The motors along the z axis were mounted on aluminum plates 40mm wide and 8mm thick, and the shafts were fixed with shf clamps

The design turned out to be very successful and RELIABLE.

Moving on to the installation of Kinematics

From aluminum strips 40mm wide and 8mm thick, I cut out holders for motors of the XY axes, as well as holders for carriages and pulleys.

As a result, I had to drill, saw, cut, plan, grind and all this on the BALCONY of the apartment, which is not very good, so in the future I will leave this process in favor of the finished version

After all the manipulations and assembly, I measured the weight of the portal without the hot end, which was 650 grams, which is not much.

Then proceeded to installation on the frame

On the same corners of 2040, installed Mosquito hotend with airflow

Now it remains to connect the electronics, since I have two motors along the z axis, I decided to connect them Consistently:

I decided to test 8 liter bottle of water

Test passed without any problems

To control printers, I used an SKR1.3 motherboard with TMC2208 drivers and a TFT V2.0 screen, and this system will be powered by two Minvil 15 amp-24v power supplies.

One PSU is used for motherboard, hot end, fans and lighting.

And the second power supply through the mosfet supplies voltage to the heating table 310 * 310 for 24 volts0003

Initially I installed a Bowden system with a BMG feeder, but then I will replace it with a direct

I launched a test bench boat and I liked everything

I tested it with a Battle, with a speed of 120 mm / s, jerky 20, acceleration of 3000 mm / s2

3

I added a little more

I was satisfied with the print quality at different speeds, but at the maximum the airflow with the PLA could not cope anymore

EVEN COMPARED WITH THE ENDER))

On this it would be possible to complete the project, but as it turned out. Many viewers do not have the ability to saw and drill on their balcony, and this assembly option is completely unsuitable for the majority.

I decided to meet my viewers and subscribers of my YouTube channel ChuchaTV and designed Samosbor ALL INCLUSIVE, which does not require the use of improvised materials and special tools.

In other words, a full-fledged Kit Kit, like from China, but with high-quality components.

I prepared a package with a file for laser cutting, bending, painting and engraving and found companies that did all these operations for me.

Mounting axle carriages and motors made of 4mm steel with subsequent painting

Table and x-axis carriage made of the same metal but 2mm thick Body sheathed with 1 mm sheet with subsequent flexible, painting and engraving

9002 All holes and the cutouts fit just perfect during assembly, I did not regret the money spent on laser cutting.

The table frame turned out to be ideal both in geometry and in strength and rigidity

Direct weight with MGN carriage 12 amounted to 350 grams

Having figured out the mechanics, I decided to install all the panels and corresponding elements

on the sides of two fans of 80mm, since more in size in size. won't get in. On the one hand there is blowing in, and on the other hand blowing out, for ventilation of the block with electronics

I put two filament holders inside

From 5mm acrylic, I cut out the door and the lid exactly to size, and on the self-assembly I printed the curtains and the handle itself a small test of print quality and the result was satisfied

The printer turned out to be very nice)) and practical

Project cost $800, although I bought most of the parts on sale days in China.

I am very pleased with the build quality and operation of the printer, but most importantly, I was able to do it without outside help, despite criticism and negativity addressed to me.

DIY Vulcanus MAX - Matrix for homemade 3D printer with aluminum frame CoreXY UP

Also at this time, the CoreXY project was being worked on, and when we saw Vulcanus V1, we immediately decided to make it.

Show 3 more images

Through experience we have expanded the Prusa i3 (Mega Prusa i3), and redesigned parts of Vulcanus V1 to be able to make 32x32x32, 42x42x42 and 52x52x52 models (this latest version is still untested).

Vulcanus Max 30 is 32x32x32, E3D V6 lite extruder, auto bed leveling and MK8 direct drive system. The
Max 40 is 42x42x42, has an E3D V6 lite extruder, "auto bed leveling" and an MK8 direct drive system.
The Vulcanus Max is thus a larger version of the V1 with structural upgrades, metal direct drives, auto bed leveling, LM10UU and LMK12L Z bearings, and acrylic panels that create the visual effect of lava.

Watch the video of the V MAX in action at The Maker Faire Lisbon 2015:

Step 1: Open Blueprints - Vulcanus Max 30 and Max 40

RepRap 3D Large 3D Printer Blueprints are open, so please feel free to upload the file sketch. The scale of the sketches is one to one.

There are 2 versions we tested and they work 100%. Vulcanus MAX 30 and MAX 40.

Use the measurement sketch and Vulcanus V1 instructions to assemble your machine.

Step 2: How to Build the Vulcanus MAX 30 and MAX 40

Start by opening the 3D sketch from the previous step. There you will find all sizes of smooth rods, aluminum profiles and acrylic panels. Use the sketch as fully as possible to get all the necessary information from it. The assembly process is the same as V1, using materials and parts from V MAX.

Step 3: List of different parts from Vulcanus V1

People building the device often have questions about the specification, so here is the document with it: [google doc] so most of the parts are different:

The length of the Z-axis smooth rods is 12 mm instead of 8 mm (for rigidity).
XY-axis smooth rods are 10 mm long instead of 8 mm (for rigidity).
XY axis will use LM10UU bearings instead of LM8UU.
Z-axis will use LMK12L bearings instead of LM8UU.
Extruder is MK8 Direct Drive instead of original Vulcanus V1 extruder.
All parts redesigned to accommodate larger bearings and larger rods, except for corners and Z axis motor holders.
The aluminum printing plate is 5 mm thick.
Red acrylic panels instead of metal.
LED strip on the top and bottom of the second base.
V MAX inductive sensors are used for automatic leveling.
Using repetier firmware instead of Marlin firmware (because I'm more used to repetier).

Step 4: Download all files from Thingiverse

All files available on thingiverse: All parts fit both Vulcanus MAX 30 and 40.

Step 5: Heated silicone platform 40×40 cm and 800 watts. The platform is attached to an aluminum plate using high temperature resistant silicone. After fixing the silicone on the plate, you need to connect the cables to the solid state relay.

Step 6: Solid State Relay

The solid state relay on the homemade 3D printer should turn the silicone platform on and off.

Step 7: Dual Extruder

Show 7 more images

Still in the process of being tested.

Step 8: COREXY Bearing Updates

Vulcanus 1 uses 2 bearings in the XY axis, this solution allows the belts to move freely over the bearings, but due to this freedom the belts touch each other while the XY axis is running. In tackling this problem, we found that one bearing worked great and that allowed the system to avoid touching the belts.
