Project Overview
April 16, 2023: This project will be updated in the coming weeks. There is an article on LinkedIn about this project, here: https://www.linkedin.com/pulse/demonstration-power-powershell-lance-fordham
This project shows how to convert an Ender 5 3D printer into a dual-use printer and laser etcher. The code and other files are offered without warranty or guarantee they will work for you. I also don’t offer guidance aside from what is presented here.
Electrical Conversion
The fan signal of the Ender 5 is used as the controlling signal for the laser. In my case, the fan signal is a 24 Vdc PWM signal, which needs to be converted to a 5 Vdc PWM signal. I do this with a simple resistor divider circuit. A PCB was created to facilitate connecting everything. You only need the resistors and the JST connectors. Get the PCB from OSHPark here: https://oshpark.com/shared_projects/3DCg3O8A
PowerShell Code
There are several different ways I could have written the code for generating the images and G-Code, but I wanted to challenge myself by doing everything with PowerShell. With this PowerShell code, I only needed to create images with rectangles and then convert them to G-Code. There is also a converter from G-Code back to an image to see if your G-Code is correct. You may not find the Designer useful if you need something other than rectangles. In that case, you can create your image outside of PowerShell if you make the image dimensions 830 x 830 pixels. The ImageToGCode and GCodeToImage modules should still work for you.
Save the files as named, put them into the same directory, and run the ImageToGCodeForm.ps1 file for the GUI.
