changing Machine zero

[artkraft]

I have a problem with the machine Z zero changing the first time I hit cycle start. The amount of change is consistent for each file. I can set top of part and jog all over the place and properly return to Machine Z or part Z 0. Firsts cycle start changes sometime before it reaches bottom depth of cut. The amount of change stays the entire file. Any ideas or solutions.

Have you got a tool offset set, is there a G43 H1 of something like in the program.

There is a G43 H1. However it works on 20 different files. I'm thinking I have a corrupt G code file.

Check the offsets table and see if there is a figure in tool 1.  If so remove it e.g. set it to zero

When you say machine zero changes, are you really meaning machine zero as it should only be possible to change that by homing or via a macro.

I think that it is actually missing steps. It sends the step commands and Machine zero DRO moves accordingly but routers don't. Then when I ref Z again it is off by the missed steps. My thought was how can Machine Zero change. I have created another file and it worked once. I am trying a couple new files now.
 I have had trouble with this controller from day 1. When I would toggle a new user button with the touch screen or mouse it would also toggle the last button used.
It would also change the direction on the arrow keys. Example activate left arrow key router moved X+ come back an hour later and it would move X-. Go into fig and the #s were swapped. I have returned it once and I am trying to get them to send another system. Maybe it will happen this time.

If you attach your xml I will look to see if there is a problem with your config.

Do you have a license file with your name in it?

I have been working with tech support from the company I purchased the controller from. Today I have been informed they shipped a new controller. I guess there has been enough unexplainable guirks that they no longer want to waste time working on it. Hurray!!!.

This is what was, Cut 540 parts 12/13   ;N06 G43 H1 Z.25  N07 G01 Z0. F160. N08 G41 D1 X1.5 F144.

 This is what they say needs to be ;N06 G43 H1 Z.25  N08 G41 D1  N07 G01 Z0. F144.  X1.5

 The changing Z0 is a missed steps. They determined that it was sending all steps at once. Too fast for motors. New controller should be here Monday maybe that will end all problems.
Explain this 40885 parts have been cut since July 15 with what was. Why does it no longer work. I will try to look at original Config and compare to current. If I can figure out how.

Thanks

Seems that the problem with the skipped steps was the HD. Replaced it and 1st program ran fine.
