You probably then want to zero-out the offsets (G49) before probing and finally load the new offsets at the same time as issuing the M6.


I think we are OK on the G49. It is already in the remap code, but #<_selected_tool> still refers to the old tool. Where do I have the value for the new tool? It doesn't seem to be set until after M6 is complete?

Thanks,

Which prolog are you using? The one I just looked at uses #<selected_tool> without the _

You need to do the M6 in your remap at some point anyway, why not do it early in the routine so the numeric parameters are accurate?

I am out of my depth here, as I am using sample code (the entire remap thing - see reference at the beginning of the thread) that I do not thoroughly understand. There is no M6 in it that could be moved and adding one, I thought would be difficult too, since I did not have access to the tool #. However, just throwing in an M6 early in the code without parameter DID make all the difference! Looks very promising. I think you cracked that very difficult nut, Andy!
Thank you so much!
