As I plan on upgrading my X2 by greatly increasing both X & Y travel with leadscrews, I may need to look at mapping the screws. I have looked at the MACH 3 Screwmapping function and understand what it does but am confused on how to use it. Are there any instructions or example of screwmapping available?

I have not used that function   It was something that was added a long time ago for only a few users... There should be a section in the manual on it

Brian,
Thank you for the reply, but after re-reading all of the currently posted documentation I am unable to locate Any reference to "Screwmapping" Is there any of the documentation from the time it was added available?

Talked to Art and he told me that you need to put the position that the table SHOULD... Hope that helps

If you post on the yahoo group there may be a few others over there that can help Very sorry I don't know that section....
