Ciclop 3D scanner: production and assembly of the control PCB – 2

Spread the love

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.

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.

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.

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

Here the new board active and mounted.

Solder the components on the milled PCB

Now we add the components to the board after the assembly process.

Here the PCB from PCBWay.

And here the result.

And here the finished PCB with compoents.

Ciclop 3D scanner PCB v12 with components

Now we must start to add all electronic cable, I explain how to in the next article.

I use 12v 2A power supply (to the barrel) to power a stepper driver.

The USB connector is sufficient for laser and Arduino, but the power supply is for the stepper.
