Problem- Incremental Vs Absolute mode

[chilly2k]

I'm trying to setup the auto zero Probe and running into problems. From another thread I was able to conclude my problem dealt with incremental Vs absolute mode. (G91 vs G90). I tried coding a GetIJMode to find the current mode and reset to absolute if it was incremental.
The problem I'm finding is GetIJMode is returning the IJMode set in the configuration panel and not the actual IJMode that is active.
Also the IJMode indicator on the diagnostic page also shows the setting and not the actual mode.

I'm running Mach 3 Mill Version R3.042.020

Thanks Bob

IJ mode is not G90 and G91. You're talking about two different settings.

Off the top of my head I don't know how to tell whether you're in G90 or G91 mode??

Gerry,

Thanks for streering me in the right direction. Here is the code to set the mode.

MoveMode = GetOEMLED(49)
If MoveMode <> 0 Then
Code "G90"
Code "(Mode was incremental)"
End If

Then to reset

If MoveMode <> 0 Then
Code "G91"
Code "(resetting incremental mode)"
End If

The messages can be deleted. They were there for testing.

Thanks Again. I think this solves my problem.

By the way. A complete Newbie question. What is the difference between IJmode and co-ordinate mode?

IJ mode is for arcs, it specifies the center point.

When I posted before, I was looking for that LED number, but I think I was looking for a DRO by mistake.

If you're interested I have rewritten my Zero Macro to take care of the G90 G91 issue.
