I have attached the pdf document for the driver board I am using. As for the stepper motors, they appear to be standard NEMA 17’s. I haven’t found anything different about them compared to any other 17’s I have seen online.
Also, I have the same pulleys with 16 teeth. In my settings I have the teeth set to 1 instead of 16 because of what I have read online about how to set up LinuxCNC when using tension belts. It is my understanding that the setting in the screen shot were originally designed for lead screws so some conversions are required. I read some posts about this and stopped making changes once things appeared to work and the scale was correct. I am not 100% something isn’t incorrect that might cause the issues shown in the video.
