loss of jogging control
« on: January 20, 2021, 11:44:00 AM »
Help please,
I have started to use the denford orac lathe that I have converted to stepper drives with CNC4u drives.
I have run a few small programs using the free download for Mach3. I will buy a licence when I have ironed out a couple of small bugs with the lathe.
Today I have run two very small programs with no problem until now. I was changing to the second program and suddenly the manual jog failed to respond. at first the rapid/shift jog failed to respond, only slow jog, now totally frozen.
I can run the first program with not problems. and in manual mode the Jog light is lit and if I press incremental jog, the machine jogs the increments in any direction.
I have tried another keyboard and no change.
I am not a PC head so simple answers would be appreciated.
