X and y connections work great. Swapping motors - after shutting down confirms that the motors and wiring is good. Z axis pot has does not seem to work
I purchased 2 grblshield 's so I will test the 2nd one tomorrow.
Suggestions?
Z axis not working
Sorry, typing on an iPad sucks. My English really isn't that bad
I have tested the 2nd board and the z-axis is working just fine. As stated above, the z-axis pot on the 1st board does not seem to work.
Sorry you are having problems with the Z axis pot, and thanks for diagnosing it. Please contact us off-list and we'll exchange the board.
