Re: Stepper won't go in consistent direction

Hi everyone, As it turns out, it was the grblShield. I ordered another one last week with the Shapeoko modification from Synthetos, LLC, and it came yesterday.

I am using manual control in the Universal Gcode Sender running on a Linux laptop. X and Y manual control functions normally, but Z control seems to randomly go in differen...
