Try putting a G94 in the code

Sounds like your using G95 mode, which requires an F work on every line.

Gerry testing HERE from the MDI and GCODE program

G90 G90.1  switches to Abs IJ

G90 G91.1 switches to Inc IJ

(;-) TP

Try this

G90 G90.1

G91 G91.1

And you'll end up in G90 G91.1. Not what you're expecting.

Comp in Mach3 has several bugs. Based on your code, it appears that it doesn't like G92 (or G52)
I'm not sure if any of the bugs are actually documented anywhere. The only ones I've ever really encountered where with specific geometry that the comp just wouldn't deal with.
Basically, if you do a proper lead in and lead out, it works about 99% of the time.

As for the manual, (and Mach3 to an extent), it is what it is. The manual was written by a third party many years ago, and is woefully out of date. I believe that the comp section was taken directly from the LinuxCNC Manual (LinuxCNC was the basis for mach3's trajectory planner)
The manual has never been updated, and never will be. Mach3 is currently in a similar state. Over the years, it evolved into such a complex package that bug fixes become nearly impossible to do without adding more bugs. For the last few years, the programmers have been working on Mach4, which is a complete re-write.

One thing about the G91.1 that most people don't realize.
It MUST be on a separate line from G90 or G91. They are in the same modal group, and if they are both on the same line, the first one will be ignored. Try this as a test, using MDI.

Type G91 and hit enter.
Type G90.1 and hit enter.
Type G90 G91.1 and hit enter.
You'll notice that you're still in G91 (incremental) mode.

When loading g-code, click the "File Type" dropdown and select .txt or "all files", and then open your .txt file. After you close and restart Mach3, it will only show .txt files.

When you enter 10 in the DRO and press goto zero, the tool is moving from 10 to 0. When you do G0 X10, the tool is moving from 0 to 10. Opposite directions.

Go to Config > Ports and Pins and see what it's set at.

If you're running a higher kernel speed, try reducing it.

1) E-Stop or De-Ref Axis button. Probably the Stop button as well during motion.

2) I'm with Hood, and think the best thing to do is remove it altogether. It really serves no purpose other than to annoy you.
