The obvious advantages in the service of your business:

Massive steel stanch with a looted structure. Movement of the saw carriage - on cylindrical guides. Saw carriage with lifting saws along TNK guides is a guarantee of machine reliability for many years. Separate lifting of saws (available option).

Process control on a modern PC with a program in Russian

Label printing - synchronized with part output (option available).

Front tables with independent blower and moveable (except base).

Automatic horizontal single line sawing machines for cutting boards made of wood and its derivatives (chipboard, MDF, plywood, fiberboard) equipped with a PC/PLC based control system.

- Base - tubular steel structure.

- Table - steel construction with stiffening ribs and reinforcing elements, bakelite work surface.

- Saw carriage guides - cylindrical, saw carriage has a balanced design - lower guide bearing - upper leveling.

- A ruler for locating plates at right angles to the cutting line is located on the left side of the table.

STEEL SAW CARRIAGE

- The saw carriage is a rigid steel structure that holds the

- INDEPENDENT MAIN SAW AND SCORING SAW MOTORS

- Power 9 and 1.3 kW, respectively;

- DRIVE-GEAR-RAIKE

- Prismatic guides and linear bearings with ball recirculation for vertical movement of the main saw;

- Hardened ground linear rollers;

- The correct distribution of masses on the carriage ensures high quality cuts;

- The working movement is carried out in the direction of the ruler for locating plates at a right angle.

- Saw fixing system: PNEUMO

PRESSURE BEAM

- The pressure beam acts on the plate with a force evenly distributed along the entire length of the cut. Special cutouts eliminate the conflict of the clamping beam with the grippers during the cutting process. The vertical movement of the beam is carried out from a pneumatic drive using high-precision pinion-toothed rack pairs. The operating pressure is adjustable from 1.5 to 6 bar.

- Dual wood dust extraction system: one dust collector is mounted on the pressure beam and serves to clean the table, the second is located on the bottom of the saw carriage.

Single automatic aligner:
* with air cylinder parallel to the cut line, running on prism guides on linear bearings with recirculating balls (THK)
* travel: 1200 mm
* minimum workpiece to be leveled: 60 mm
* maximum workpiece to be leveled: 1200 mm

PUSHER AND REAR OF SAWING MACHINE

- Driven pusher acts along the entire working length of the sawing center and is driven through a large section torsion bar. The translational movement of the pusher is carried out along steel guides H-profile . Two precision gears are used to transmit the movement, which ensures that the parallelism between the pusher and the cutting line is maintained. The pusher motor is connected via an inverter, which allows you to control the speed of positioning and fast return.

- Adjustable gripping force

At the rear of the panel saw there is a tubular structure on which rollers made of non-abrasive material are fixed. A table with a bakelite surface (350 mm wide), located on the side of the ruler for locating at a right angle, makes it easy to cross-cut thin strips of material.

- Corner clamp - independent roller made of wear resistant material.

Positioning of the pusher is carried out using a non-contact measuring electromagnetic ruler of increased accuracy (10 times compared to a mechanical encoder).

3D printer Anet ET4(X)

As you know, preferences in 3D printers are a religious issue and there are more dogmas here than anywhere else. Dry-table, rails, CoreXY, direct extruder, bowden are more religious than technical terms.

Those who want expensive and rich buy a printer on rails. Well, who is content with cheap and cheerful - this is what it is when carriages on plastic wheels roll along an aluminum profile. In general, it is quite a viable and very cheap solution, it is used now where it is possible and where it is impossible.

The profile of this printer, by the way, is also one of the cheapest - 20x20 and 20x40mm, nevertheless, it is enough for the rigidity of the structure.

I already once wrote about the history of the purchase of this printer - at that time there was confidence in 99 percent that I won't get it. Readers didn't like the article and had to delete it.

The printer was ordered out of need - I managed to break my old Anet A8 and strongly doubted my ability to quickly fix it - parts from China do not go quickly. And then a very cheap printer with delivery from the Czech Republic caught my eye, they promised delivery in just a week. On the seller's page, right below the price, there was some kind of coupon, click it - and the price generally became fantastic.

By the way, this price includes the VAT required by the EU from this year (for Finland it is 24%), according to the documents, the seller received only 85 euros.
But a week passes - and the printer is not even sent. Sending time expires - extended it by 3 days and wrote to the seller. When there were literally a few hours left before the order was closed, the seller woke up and wrote - and we do not have Anet ET4X in stock, but we do have Anet ET4. Already not really hoping for anything, I am writing - let's have it, if for the same money. And a miracle happened - he still sent the printer. True, for three days the tracking number was nowhere to be found, then the Finnish post office discovered in the vastness of the universe some kind of parcel with a completely different number, coming from Germany to my address. I am writing again to the seller - did not I confuse the number? Yes, I beguiled - but in the end, the package ordered and paid for on October 24 by November 10 reached me. For all that, it was written in the lot - delivery in a week or a refund.
During this time, Frankenstein's monster was built from Anet A8 from improvised means and, at the very least, earned. Instead of a conventional extruder, I had to install a bowden - obviously, the printer began to snot a little, otherwise everything was very even nothing.

As a result, the newly arrived printer stood still unpacked for several days, but finally its day has come.

In the box, in fact, there are two large parts - the upper part and the stand box, which need to be twisted together with 4 screws. This is almost all the assembly work, well, also put the X-axis carriage with the extruder.
There are several bags separately, one contains an assembled extruder, the other contains a PLA probe - very beautiful, with a silky texture. A set of wrenches for assembly and adjustment, bolts and nuts, an SD card with a USB adapter, a spare nozzle. Bracket and tube for mounting the spool with plastic - but it's better not to mount a heavy spool on top of the printer, as the manufacturer recommends.

Why did I have a desire to buy a designer, and not a pre-assembled printer - I did not believe that the eccentrics would be adjusted well and thought that I would still have to disassemble and adjust everything. But I underestimated the progress of the printer-construction industry - everything turned out to be perfectly regulated and there was no need to go there.

For those who prefer more detailed photos:

What else is interesting on the frame? Below in the photo is a Z-axis stepper motor, an X-axis motor, a filament presence sensor and a bowden.

The axle carriage with the extruder, as I said, is proposed to be installed by yourself:

Pull out the stand. It comes with a self-adhesive plastic table pad. Why is it needed if borosilicate glass is already attached to the table - I don’t know.
The table is fixed with foamed polyethylene and green plastic inserts are inserted into the slot of the profile, which will prevent the table from rolling in case of any blows to the package.

For once, the heater wire is securely screwed to the table, the collective farm is not needed. Power supply - 24 Volts 240 Watts.

The frame is attached not to the support box, but to the aluminum profile inside the box. The rigidity should be quite sufficient so that you can move the printer from place to place without additional calibration. Its predecessor, Anet A8, is a rather flimsy design, despite its bulkiness, and any rearrangement leads to the need to align the table on a new one.
Four screws are all that really needs to be screwed in order to assemble the printer, there is nothing more to twist, just plug in the connectors.

The photo shows that the Y-axis belt tension can be adjusted by moving the motor. You can - it doesn’t mean you need it, my belt turned out to be tensioned very well.

The glass is already attached to the table with small neat brackets, no need to collective farm with binders that stick out in all directions, like Cheburashka's ears, and interfere. The table springs are very good, with a flattened profile, leveling the table with them is a pleasure. Relative, of course - there are not many lovers of leveling it, but what to do?

Once the top is screwed onto the bottom, it's time to install the carriage with the extruder. Use force, Luke © - with a slight pressure, the carriage slides into place.

It remains to install the belt and adjust its tension by changing the position of the stepper motor.

Wires do not stick out in all directions - all the wires of the upper part are connected to the adapter card, and from it a flat cable goes to the lower part.

In the instructions, it is recommended to attach the spool of plastic to the top profile of the printer - I don't think this is a good idea. The construction is not strong enough to hold another kilo on top. The lever turns out to be large, and the frame is mounted only on 4 bolts screwed into the end.

The assembled printer looks like a factory product, not a do-it-yourself kit.

The software is perhaps too concise.

The best video on table calibration - briefly, only to the point and no one is gundosing, from the manufacturer of this printer:

Have you looked? Here's what I'll tell you - in our time you can not trust anyone, sometimes even yourself. I can.

It will not be possible to adjust the level so normally.
Next is my calibration method, which does not pretend to be a dogma.
Level sensor is not a fountain. If you try (not with the help of a built-in program that does not want to hamster only along the Z axis, but programs on a PC, pronterface, for example) without touching other axes, just hamper along Z several times - the spread will be 0.1 ... 0.2 millimeters - and this very much, layer thickness. Moreover, what they offer to do in the video - fitting through 0. 1 mm - is also not good. Because with a normal axis setting, the motor pretty quickly brings the sensor to the trigger point, then raises it a little and goes to the point again, but much more slowly so as not to slip through.

Before starting calibration, you need to heat up the bed and head to the operating temperature of the plastic you are going to print with. If you print PLA and decide to change it to ABS, the sensor calibration, in a good way, must be repeated.

I've always used mikrik end caps so far - 0.1mm accuracy has always been achieved without problems. In A8, it was possible to use a limit switch or an induction sensor - after several attempts, the induction sensor went down the drain. Here the sensor is like capacitive and reacts to any material, not just metals. With the surface of a chipboard table, it works quite well. What is inside it is interesting, but I did not find it.

I don't believe in automatic calibration at all, because the Earth is flat :) As I already wrote, 3D printing is more of a religion than a technology.

So, calibrate the sensor and level the table. The description is only for those who are dealing with the printer for the first time, it is better for the rest to skip it.

The first approach is the most dangerous with such a sensor - if the sensor is not configured, it may never come to the table at the right distance - the motor will press the nozzle on the table until the glass breaks or something else breaks. In my printer, the sensor was set up pretty accurately, but you shouldn't count on it.

Therefore, the safest thing is to adjust the head to the center of the table with your hands. Then, with your hands, slowly turn the lead screw Z until it slightly presses the piece of paper placed on the table - so that the piece of paper with some resistance can be dragged through without tearing. The paper should be only under the nozzle, the sensor should not see it. Now we turn the tuning resistor on the sensor so that the sensor just turns on in this position. The setting is very sensitive, it's better not to even breathe :)

By the way, the attached screwdriver turned out to be too bluntly sharpened - it did not enter the slot of the tuning resistor.

After that, using the program on the PC, hamster Z and see how the paper is pressed and adjust the sensor again. After several iterations, the result will be more or less.
Now align the table itself with the adjusting screws with heads. The heads are large, leveling the table with their help is very convenient.

When the Z-axis is at the zero position in the center, raise it with the program by 1 mm. Do not touch Home Z again in any case - otherwise you will have to repeat everything from the beginning.

We adjust the head by hand or with the help of the program to some corner of the table. We lower the head by 1 mm to the initial zero position. With a screw we set the height of the table in this corner using the same piece of paper. After setting, you need to check again - raise the head by 1 mm and lower it back. The height can go a little - you have to adjust again - and so on for several iterations. Then we go to another corner. Do you think that when you adjust all 4 corners, you are done? Nothing like that, when you adjust one corner - the second goes astray. In short, under ideal circumstances, you will have to go through all the corners at least once and repeat or check the setting. It's a chore - but who is easy now?

I use Slic3r normally, but I don't have a profile ready for the new printer. Therefore, you will have to install Cura, since it is cross-platform and generate a G-code using the settings offered by the manufacturer - and such an experiment will be cleaner, with a slicer you can mess up a lot and get a disgusting result even using an ideal printer.
I must say, I was dreaming about cross-platform. Newer versions yes, but newer versions don't understand attached settings. I had to install ancient Cura 17.04 on a virtual machine with ancient XP and generate code using it. Then I dumped it on SD and went to try to print.

I put the printer to print and went to write about what a good printer is and how it works “out of the box”. But this was the end of the "caropka" - the top of the test cube remained underprinted. Did the nozzle clog so quickly?
I'm changing the nozzle - fortunately there is a spare one and a dozen more lies in the gas holder. I recalibrate the table - the stone flower does not come out. Plastic does not extrude. In the beginning, it chokes a little - but not enough, then it stops altogether.

I had to disassemble the head. The reason turned out to be simple, and most likely it is a combination of two reasons - the PTFE tube did not reach the stop by several millimeters and the temperature of the heater in the attached installations for Cura was 190 degrees. A viscous plug formed inside, the plastic went where it didn’t need to, and it was no longer possible to melt it there. After installing the tube to the end and increasing the temperature to 210 degrees, there were no problems. I think I just got very lucky with a poorly installed tube, and this is a problem of a particular instance.

After this small repair, printing went without problems. Cura makes a "raft" for printing by default - for this printer, this is very justified. Still, the accuracy of the sensor leaves much to be desired, and with the "raft" you can do without good accuracy.

The rest I printed without a "raft", but in this case, the printer needs attention. Sometimes the first layer starts to lay a little high, you have to stop printing and start again.

Test figurines:

And a little more detail:

Cat OTK at work.

After A8, the table heats up very quickly - it warms up to 60C in two minutes.
The filament end sensor is also quite working - when the filament ran out without printing the figure, we managed to replace it. True, the head moved a little - the figure shows that the layers are slightly shifted. If the printer is suddenly turned off while printing, the display prompts you to continue printing when you turn it back on.

My opinion - this printer is worth the money, whoever disagrees can be the first to throw a stone at me. I have not been able to find anything like this for close money.
