Hi. I just adopted a K40 with a Moshiboard MS10105 (ribbon cable variant), which I’ve never tested due to the USB dongle missing. I replaced the stock board with a C3D Laserboard running the Smoothieware firmware that it shipped with.
From what I understand, on power up the stepper motors should home to the <0,0> position. However, the motors do not move at all. If you unplug and replug the C3D PSU you can hear a subtle bump from what I think is the Y-axis motor. I’ve also verified that the motors are powered to some degree because they become stiff and difficult to move when the system is powered, but I can move them easily by hand when the system is powered off.
Here are photos of my setup.
Any help would be appreciated!
