hi
I constructed pcb drilling machine with leadshine driver and stepper motor 2A running on mach3.
I m facing a problem. The Z axis moves as
Z0
G1
Z-3
G0
Z3
It moves as instructed but moves few steps up more. After 20-30 holes Drill gradually goes up and doesnt drill at all.
I tried with Active Low for direction but still it moves upward gradually. I reduced acceleration but didint work.
What could be the reason kindly help.
Thanks
