I installed a new Z-20 slider with a PwnCNC air cooled spindle. Everything was fine when first installed. I did have to upgrade the BB firmware to the latest to include the PwnCNC spindle as a tool.
After setting for a while I fired up the machine today and z-axis homing just vibrates away. I had to e-stop the machine and look up how to fix this issue. I have the stall amps set at 4 to get it to work but it sounds terrible. Is this normal? Is it safe to leave the setting at 4 from the factory setting of 1.
Ran a sample run and it worked well but wanted to make sure I am not going to damage anything.
PS>. downgraded the firmware to 1.2 (latest gold code) and had the same issue. Back up to latest beta for BB.
Thanks!
