Hi, I’m owner of this little blue machine. I’m upgrading the controller board and I found the “system” pulse per inch that improve quality instead of pwm.
The problem is that I couldn’t find a firmware which incorporates a ppi system. The closer I could find is the M4 code in grbl 1.1 to engrave and cut. The rest, as I understand, are different systems programmed to use ppi and they connect to the main board ( a cohesion3D, a smoothieboard, or other type of controling boards).
Is all of this correct? Or do you know any firmware with ppi implemented and it can be programmed in a board such as cohesion3D?
Thanks a lot
