Terry,

I am strongly suspecting that it has something to do with named external
subroutines. I have used coordinate systems (G54-59, G10 L2, etc.)
extensively in the past without any problems. This is the first time I have
used the tool table for X, Y, etc. offsets, but the problems I am
encountering are similar enough to what I was seeing with coordinate systems
that it seems it must be related.

The main difference with this application is the extensive use of name
subroutines. However there are no motion commands in any of these
subroutines, they are mainly for asserting digital outputs, checking inputs,
applying dwells, etc.

This is on a production machine, so I have limited ability to run tests on
it, but I have just put a box together for simulation purposes. I should be
able to do some better problem isolation on it over the next couple days.

I am open to ideas as to what to look for.

Thanks,
Eric


G49 cancels G43
Se just nd the machine home at the end of the prog using:
G28G91Z0.0  Y0.0  X0.0
 You should not need to use G49
You must be doing something else wrong

Start of every one of my  progs look like this:

T1M6
G54G90G0XxxYxxS500M3
G43H1Z.1M8   moves the tool down to .1 above the workpiece blah blah

ends look like this:

G28G91 Z0.0   send the Z home
G28G91Y0.0   send the y home to put in a new part
M30
