I’m trying to learn G-code

I’m a 3rd year mechanical engineer and I think it’s a good practice to put myself in the shoes of whatever poor soul has to actually create my idea. It took me 6 hours to make 8 slots in an aluminum plate(on a terrible 3 axis cnc) with the help of a someone who barely knows G-code. So, I was wondering if there’s a software to practice G-code without having to worry about destroying bits or destroying the whole machine.

Change Filament G-Code without AMS

I've created custom g-code to change the filament without AMS. This makes it so changing filament in the slicer (instead of just pausing) will unload the filament and pause. Previously, the g-code for changing filament would be ignored if there was no AMS and would continue the print.

I couldn't find the actual g-code to cut the filament and unload the filament anywhere, so I just added G1 codes to try to mimic the motion that occurs when pressing the unload filament button. I also added the code to extrude forward a bit, and then back it out. I've only run it a few times, but I haven't had any issues loading the next filament in.

Github link: change_filament_noAMS.gcode

This code would replace the code in Bambu Studio. Click to edit the preset circled below, and then replace all the code in the highlighted box under "Change filament G-code"

If anyone else tries this out, could you let me know how it goes?

edit: Be cautious! It worked for me, but I would test this on a small part and change the filament every few layers to make sure it's doing what you expect it to do.
