For some time now I have had a problem with my A axis on a clockwise turn getting a error.. I have changed the gecko, breakout pcb, parallel port cable, computer, reloaded new versions of mach3, erased the hard drive and reloaded everything, took off all unnecessary programs, swapped the gecko cables, swapped the servo motor with a new one, took the motor off the assy and ran by itself with (G0 a40000) check light... run (g0 a-40000) ok... I have a K2 cnc and they have no clue what could be the problem... Anyone had such a mess...
Sometimes it works ok......Re grounded box and no help...I thought about going to smooth stepper, but don't want to spend the money if it won't help.... Some of the runs I do set (A) as much as 212,000. I tried changing kernel speed, no help. Motor speed, no help.... H E L P if U can... I am not stopped from working because I can run in CCW directiion, but I have set up to be able to run in CW most of the time...
