Mach4 General Discussion / Re: Z probing direction reversed

« on: December 20, 2018, 04:43:20 AM »

Craig,

Thanks for the info. I can confirm that my Z axis is homed at max positive i.e. fully retracted. So after reading your post I homed all axis and zero'd the DRO. I then issued a G31.1 Z-85 F100 in the MDI and the axis started going down as expected so there is something I'm doing wrong when setting the machine up. Is it normal to have to zero the DRO after homing and before probing?

Mach4 General Discussion / Z probing direction reversed

« on: December 19, 2018, 02:36:52 PM »

This has probably been answered some in a previous post however the search function is not working. So, what happens is that when I go to do a Z probe, it goes up instead of down. jogging, G0, G1 all work correctly in the Z direction. However, executing a probe in the Z axis either from the probe module or the MDI using a G31.1 results in the Z axis going up! Does anyone have any idea what could be causing this?

I have fixed it! After reading joeaverages reply, I looked at the configuration and I was correctly set to mm on both machine setup units and units mode so I decided to set both to inches and recycle the program. Jogging corrected operated in inches mode. I then reset to mm on both and restarted Mach4 and lo and behold it is now correctly jogging in mm! I don't know what caused this as it was a clean install of the latest download. Thanks for the pointers.

I have my machine newly configured in metric. Status codes at bottom say that G21 is enabled. However, when I jog 0.1000 both machine and DRO move 2.54mm, 0.1". Could anybody tell me how to change the units on the jog screen as they appear to be outputting in imperial although metric is set in the configuration?
