Alright, so here is the code for my machine that is remotely based on Pwdr. I was able to get a few models out of it, but choosing wood was idiotic, and the Y axis kept jamming. I am looking forward to get Plan B assembled and get much more time to try out powders instead of fixing the hardware over and over 😉

Here are some videos of the machine:
