Mach4 General Discussion / Re: Can someone better explain probing setup?
« on: January 31, 2016, 09:48:07 PM »If I have soft limits set my keyboard commands for the Z are reversed. By simply clicking soft limits on, up is down and down is up. Also no matter whether soft limits are off or on when I try to zero probe, the z axis travels upwards instead of down.This is a known issue with Mach4 and the configuration screen. Double check your soft limit values and note that the soft limit **MAX** is the first column and the **MIN** is the second column. If you enter, as a lot of people presume, the smaller value in the first column (which is actually the "MAX" column) and the larger value in the second column (which is actually the "MIN" column), Mach4 will not complain or warn you that you've entered nonsensical data. It *WILL* however, jog the motor in the opposite direction as you have noticed.
[EDIT] I just looked back at the pictures you posted. You do indeed have the Z axis soft limits backwards. The X and Y axis look OK. [END EDIT]
[shameless plug] Note that an upcoming version of the PMDX SmartBOB plug-in *will* check this and warn the user about it.
