I made router approx. 600x600x200 (mm) with servos and geckodrives g 320. Encoders have 500 lines.
I use mach3 as control software.
After milling I try to return to zero and every time I get error +0.5...+2mm on each axis (It depends on size of part, bigger part-bigger error).
For the same part I have the same error every time.
I don't use breakout board. I tryed breakout board, but the result was the same.
It's not mechanical problem. I have double checked everything. I see error by marks on my pulleys.
Please help me. I tryed everything and still don't know what to do.
