Thanks for your response! Yes, the printer is no longer controlled by the original board. Instead, I’m using the GPIO interface of a Raspberry Pi 4B with TMC2209 stepper drivers.
The Pi runs LinuxCNC, configured using .ini and .hal files that I set up based on examples from the web. This has been an idea of mine for over five years, and it’s one of my more exciting projects- comparable to my early experiments with photoactive resin, a DLP beamer, and a stepper motor back in 2011-12.
If there’s anything else you’d like to know, I’d be happy to share more!

I was thinking the same since he must be out of stepper driver connections with the stock board.
Multi-axis 3D printing at that price point looks interesting. Most use robot arms for that ability.
