General Mach Discussion / MACH3 Jog Step Issue
« on: June 14, 2019, 03:13:40 AM »
Mach3 on Win 7 32 bit with parallel port.
All had been working OK other than an occasional drift on the Z axis which I was about to track down the cause of when events meant I had to put it all to one side to pick up at a later date. The date arrived, and a whole bunch of Win 7 updates got installed, including the Spectre / Meltdown patch. I did the registry change to get MACH3 working again.
I am now have still an issue with jog step, all axes behaving the same. The step, for testing, is set to 1mm. When I try it the MACH DRO shows the correct movement the stepper just makes noises but doesn't actually move. I could well imagine the direction signal is whipping up and down.
Is there a known issue with other Windows updates hat could cause this? Could something have got corrupted on the MACH3 config ( it looks OK), or is there likely a hardware fault?
