g52 problem

[REVCAM_Bob]

I am using g52 in a program after a g54. Sometimes, it will not cancel,
and when running a new similar problem, the move to the g54 is all screwed up. Running on Fanuc 18i-mb5 control on a Fadal.
Can anyone tell me what I am doing wrong? My understanding is that the
g52 x0 y0 should cancel it...... but it does not always work. When this
problem happens, the only fix is to reboot the control, then the g54 moves
to the proper location again.???

Can you explain the G10's? I'm not familiar with them enough to know what it is that you are changing. Something to do with tool offsets, or work offsets?

REVCAM_Bob

You do not have any G54 commands in the program you list, just one G55 so all your G52 commands will be working from G55.

G10 enters tool offsets and work coordinates from the program. L10 is length offset, L12 diameter offset. The Haas manual describes the use of G10 in a somewhat understandable manner.

[REVCAM_Bob]

Sorry, I put in my post G54, I meant G55. Its the G55 thats getting all messed up.

[Geof]

The only comment I can add is have you tried ending your program with M30? This should cancel G52.

[cad]

I'm lost as to why you need to use the G52?
G52 is local coordinate shift. just add the values to G55 offset.

This does not answer your question, but there are some parameters related to G52 that could be affecting you. One parameter is weather of not M00/M01 cancels G52
Reset/M30 should also cancel it.
