General Mach Discussion / Re: Jog keys

Thank you very much. I must have done this when I set up the rest of the machine, but I had forgotten how.

General Mach Discussion / Jog keys
« on: September 11, 2018, 11:26:50 AM »
I'm running 3.043 under win7 using a touchscreen. I can't see how to change key assignments for jogging. The machine jogs OK in Y direction, but jogs opposite directions on X axis. Under Config|Sysytem hotkeys I'm seeing 37 and 39 as X++ and X--, but I can't see how to edit them. I can select the numbers, but they can't be edited. Please tell me I'm being silly (and better yet tell me what to do next)
Thank you

Thank you very much - problem is now resolved by changing hotkey settings.

Thanks for your response. I'm out of the works for a couple of days. I will post back as soon as I can try this.

Hi Jim
Thanks for your input.
Current workshop temp is around 21C. This problem occurs all day from 0700 (temp around 16c) to evening (temp up to around 22c). The colour change on the G Code window is just the normal change you get when you click into that window, but it is also being triggered by the lockout. The wire for the Z axis is not loose or faulty as the problem doesn't happen on fast jog (SHIFT + PageDown), only on simple PageDown. There appears to be no other symptoms on other programs that might indicate computer fault. The lockout also occurs when the driver card is disconnected, so it looks very much like a settings problem in Mach3.

Thank you for your response. As I said, reversing the direction polarity reverses the symptoms, so the problem is then showing when the PAGE_UP is used, rather than the PAGE_DOWN.

I have unplugged the parallel output - no change in symptoms. I also notice that when the system locks, the G-Code window changes colour.

General Mach Discussion / Mach3 Z axis problem
« on: July 15, 2013, 06:51:27 AM »
I can't get Z to go down on jog. All axes work fine on fast jog (with shift key). X and Y work fine in standard jog. Z works upwards on standard jog, but when you try to jog down you get no movement and all axes lock out, requiring a manual reset to get anything going. I have reversed polarity of Z direction pulse (to eliminate possible mechanicals) and the problem reverses, with requested upward movement causing lockout. I suspect this may be linked to THC, but I have disabled THC inputs and it is still the same. Under program control Z axis moves on G0 commands, but on THC (PROMA) it shows a request to go down, but no actual movement.

Any ideas please.

I have a similar problem. I have tried all the remedies suggested, but still can't get Z to go down on jog. All axes work fine on fast jog (with shift key). X and Y work fine in standard jog.
