Run-from-line and v.2.7.3

I think Andy's idea is to see if the "phantom Z move" is the g38.2 probe line is being run again, rather than just a Z move.
The rest of your sub does not seem to run as the the Z does not lift after the probe.
Perhaps...
G38.2 Z-100 F3001.0 (debug, probe result #5061)

Are you using M53 for feed stop control?

In the mean time what happens if you position the machine with a mdi move to the coordinates of the next line to run?

If I run-from-line at "G01 X250.000 F2000.000", it will -Z until the probe switch is engaged and hold that Z position while moving X to 250.000.

So before run-from-line "G01 X250.000 F2000.000" position the machine at X250.000 .

If you are using the Axis GUI then you can turn on "block skip".

If you precede the call to the probe routine with a / then it won't be called if block-skip is on.

So, a troublesome workaround might be.
block skip on
run from line
block-skip off.

I'll have to try debugging next chance I get. Thanks for the example. But, again, I think it's not just a Z move. If I remove the G38.2 from the subroutine, I don't get the -Z move before executing the run-from line.

I have tried moving to the next needed position before run-from-line, but I still get the -Z move. In this case, what happens is that I get a somewhat coordinated move: As the Z is moving down, I also get a -X to about 185-187mm which is where the probe switch makes contact and then it returns to X250.000 as the torch raises. The Z does move after the probe, but since it's a coordinated move with X and my touchoff offset is almost 10mm, it takes a little distance before the torch tip actually gets off the material.

Yes - I am using M53 for feed stop control. If it doesn't cause a problem, I like implementing it this way instead of adding it to each code file - To me it's more of a system option as opposed to a job.

I am using Axis GUI, but didn't think to use the block-skip feature. Can it be turned off on-the-fly??

I think so. This is the first time I have thought of a use for it

No, you have to stop the running program to toggle block delete.

OK - I thought of adding the forward slash to all touchoff calls, then block, run-from-line, and then unblocking for the upcoming touchoff calls. This would not work.
