Ciclop 3d scanner firmware

Ciclop based Laser Scanner — FabScanPi documentation

1. About Ciclop

2. Bill of Materials

The following list shows what you need to modify the Ciclop scanner for using the FabScanPi Software.

General components

12V to 5V switching regulator
Raspberry Pi 3 B+ or higher
Raspberry Pi camera V2
Raspberry Pi Camera Connection Cable - 50cm
Micro SD Card ( >= 8GB)
Silent Step Stick Motor driver
3D printed Camera Mount
3D printed Raspberry Pi Mount

3. Ciclop Modification

Mounting Raspberry Camera

You can use a printed camera mount to mount the Raspberry Pi Camera to the ciclop. The Raspberry Pi Camera will replace the USB webcam.

Note

The Raspberry Pi camera has a better image quality than the ciclop USB webcam.

Replacing the Motor driver

It is recommended to replace the default motor driver of the ciclop with a silent step stick driver. You can use a TMC2100, TMC2208 or TMC2009. But you need to configure the TMC2xxx driver to run in 1/16 micro stepping mode. If you decided to use the TMC2100 driver all you need to do is removing the jumpers under the ciclop motor driver. For other TMC drivers read the manual at watterotts TMC guide.

The motor driver which was included in the kit has a red or green surface.

The picture shows a TMC2100 motor driver on the ciclop Arduino Shield.

Note

You can also use the default driver, but the usage of a TMC motor driver lets the turntable move much more silent and smooth. That leads you to much better calibration and scan results.

Connecting Raspberry Pi

Connect the Ciclop Arduino USB cable to the USB port of the Raspberry Pi. Then connect the Raspberry Pi camera ribbon cable to the Raspberry Pi.

Note

You can use a Raspberry Pi camera ribbon cable extension (50 cm).

You can use a Ethernet cable for Network connection or configure the Raspberry Pi’s wifi setting-up-wifi.

Warning

The Raspberry Pi 4 needs active cooling by a fan. Otherwise the scan process will stuck or fail.

Proceed with the Power Management.

The Power Management

The fastest way is using two power supplies. One 5V supply for the Raspbbery Pi and a second one with 12V connected to the Arduino for the motors.

Warning

Do not use the 5V supplied by the Arduino, because it does not supply enough current. The Arduino and even the Raspberry Pi may be demaged otherwise.

But if you want a setup with less wires, you should add a Step-Down converter like on the picture below.

The 5V output of the Step-Down converter is connected to the 5V and GND pin of the Raspberry Pi.

Connecting LEDs (WS2812)

It is recommended to connect a WS2812 LED-Ring or some WS2812 LED stripes for a better illumination of the object. You can use the 6 pin header on the original ciclop ZUM board.

5. Software Installation

Now you need to install the FabScan sotware. Please follow the Guide for Installing the Software.

6. Software Configuration

The image installation from the previous step already contains a default configuration for the FabScan. But some values need to be adjusted, depending on your hardware setup. You should recap your motor type, and the number of lasers at this point.

Note

If you don’t know how to edit a file by using a text editor on a Raspberry Pi console, you should read detailed chapter on How to Edit the Config File first..

Motor Config

You should be sure that the number of steps matches your motor. If you are using a NEMA17 motor, the common number of steps for a full revolution is 200 (1.8 degree per step). The motor driver is set to 1/16 step what results in 16*200=3200 steps. Most of the ciclop kits come with a 200 steps stepper motor.

Warning

It is important to set a correct value for your motor. A incorrect value can cause double/mirrored looking scans results. Even the calibration process might fail.

The example below shows a configuration for a 200 step stepper motor. The cilop turntable radius is 100mm. If you are using another turntable than the default one, change the radius.

"turntable": { "steps": 3200 "radius": 100, "height": 155 }

Laser Config

Change the number of lasers to a number which matches your setup. If you are using just one laser then change numbers to 1, otherwise numbers should be 2. And be sure that interleaved is set to true.

"laser": { "interleaved": "True", "numbers": 2, "color": "R (RGB)" }

Serial Connection

Be sure that the connector type is serial and the firmware is set to ciclop. The port should match the serial port where the ciclop board is connected. Mostly the port is /dev/ttyUSB0. The baudrate should be set to 14400 for the ciclop.

"connector": { "type": "serial", "firmware": "ciclop", "baudrate": 14400, "autoflash": "True", "port": "/dev/ttyUSB0", "flash_baudrate": 115200 }

Calibration config

You need to change the calibration board config to the ciclop calibration board values.

"pattern": { "square_size": 13, "rows": 6, "columns": 10, "origin_distance": 35 },

Note

Read more about the calibration configuration in the advanced Advanced Configurations section.

Leave the rest of the file as it is.

7. Using the Software

You can proceed with the software First Steps with the Software . A more complete software manual can be found in the section Software User Manual. Don’t miss to read the section about Calibrating the Software.

Note

A precise calibration is the key for good scan results!

In this article I would like to show my custom PCB for the Ciclop 3D scanner which is fully compatible with the original ZUM.

Ciclop 3D scanner electronic PCB soldering

I made my own PCB to replace the original ZUM SCAN one (bigger and more expensive). I also share it on PCBWay.

Ciclop 3D scanner board v1. 2 PCBWay

Ciclop 3D scanner PCB v12 photo prospective

PCB v1.0

This is a fully functional version (videos are made with this version) and it was the simplest. In version v1.2 I thought about adding a resettable PTC to avoid burning the engine (it never happens usually), I made my version with an old Epson Stylus Color 460 stepper motor.

I wrote a guide on how to reuse the old stepper motor “How to reuse 4 and 6 wires stepper motors for your projects“

As I said, the PCB is fully compatible with the original one. Zum scan is more complex, but all additional features is unused.

Ciclop 3D scanner board v1.0 schema

My version is for Arduino Nano, so It’s more little than the original one.

PCB Etching

I never used this technic, but I add to this step the svg file or PDF for production.

Milling PCB

I use this technic for my personal production, I think you can find interesting this series of articles “Cyclone PCB factory: how to build It” and “Milling PCB tutorial“.

Milling PCB: the Milling Process

First mill the copper bottom, then drill the holes.

Here the first traces pass.

And the finished work.

Milling PCB: clean the milled PCB

Than use sand paper to made the board flat and clean. This is my first version, in the next paragraph I add the updated version.

PCB v1.2

As I said, I later created a PTC resettable fuse board, (1.85A 30V) this simple component protects your stepper from the current problem. This card is fully compatible with the original one.

Ciclop 3D scanner board v1.2 schema

So to test the board I restart the whole milling process and here is the result

In this article I will try to answer most of the questions received in PM on assembling the scanner.

Firstly, the scheme is very simple. Whoever is in the subject will immediately understand everything! ;)

Hex firmware and programmer in one archive https://yadi.sk/d/Osx0nHOTgQTmR. This programmer works directly through USB Arduino.

Board layout in layout5 https://yadi.sk/d/TSrsSwFGgLJz2 .

If you decide to print body parts on a printer, it is better to cut the webcam mound into three parts https://yadi.sk/d/O1D0PyyJgQTti . But you can also cut out the body parts from plywood and also connect them with M8 studs. And you can assemble a scanner from anything at all. Its main dimensions are the distance from the camera to the center of the table 310-315 mm, the ears for lasers are set at an angle of 30 degrees. to the camera plane, their length is 15 cm from the center of the camera to the lasers. If the lasers are installed on the same plane as the camera, the distance between the lasers should be 200+200=400 mm.

Chinese lasers with a focusable lens should be adjusted to project the thinnest line and the focusing thread sealed with instant glue (cyacrine). Otherwise, the calibration of lasers can be lost from the slightest shock, as these lenses hang on the thread in the laser body.

Calibration must be done strictly in order, including camera calibration with different positions of the calibration chess field in space. It is better to calibrate the lasers several times and choose the closest repeating values.

That's pretty much all you need to get started with the Ciclop 3D scanner for the first time. :)

As a result, I will have to do it on Arduino Uno, since I miscalculated with Nanami.

I've already stumbled on connectors in UNO;)

We've arrived. Horus does not see UNO's COM port.

And in the device manager, instead of Arduino UNO, it says Ch440. It looks like you have to reflash the bootloader.

Here is the correct scheme for flashing UNO (Duemilanova) via MEGA 2560. Only I have a 100 microfarad conduit (probably will do). I will check.

Arduino UNO bootloader firmware steps ( Duemilanova), via Arduino Mega:
[ Click to read ]
step 1 - Nothing is connected to Mega except USB cable. Launch the Arduino IDE. We set the Mega parameters: Board, Processor, Port.

step 2 - Go to menu File -> Samples and click ArduinoISP. The sketch of the ArduinoISP programmer is loaded into the editor. Press the round button with an arrow to the right "Upload" and upload the sketch to Mega.

step 3 - Disconnect Mega from everything and connect to UNO (Duemilanova) according to the scheme (above). And we also stick a capacitor (I have 100 microfarads). We connect Mega via USB to the computer.

step 4 - Now in the Arduino IDE set the parameters for UNO (Duemilanova): Board, Processor, Port

step 5 - Go to Tools -> Programmer and click on "Arduino as ISP". Now our Mega has become a programmer.

step 5 - Flash bootloader on UNO (Duemilanova) via Mega. In the Tools menu, click "Burn bootloader". Both boards should have blinking LEDs. Ready. We disconnect everything.

I tried to reflash Bootloader according to the scheme in UNO. Everything blinked and flooded, but in the end nothing came of it. Apparently the fuses are wrong.
The Arduino Nano got free and I connected it to the computer.
