This is my first post.
I have just started to use my smoothieboard for a CNC application. I had all 3 axis running smoothly and homing correctly. I had issues with the limit switches and in trying to sort that problem I seem to have caused another problem.
I cannot remember the sequence of events but (I think the Z axis overshot) but as a result all axes started to move very roughly (missing steps?) I noticed LED 2 was off. I reset everything and homed the z axis it seemed to home smoothly, however when I tried to move the z axis upwards it was very rough again. I looked at the lights and LED 2 was solid.
I have searched here and a solid or off LED 2 is a firmware issue. I would appreciate any help on how to solve problem.
