As I'm not sure where to post this question, I'll try to get an answer here.
I have a Arduino CNC shield v3 (running grbl 0.9j) connected to Universal GCode Sender (platform).
Works all just fine, except with one very annoying problem...
My (DIY) CNC router its Z-axis automatically lowers due to (little) vibrations made by the router.
That's a big issue as the machine its Z-axis is no longer in line with the home position at that point.
Is there a way to force the stepper drivers to keep current flowing to the motors, even if no gcode is sent?
If this is not the forum to ask, please advice.
