All, LinuxCNC uses the TnM6 command for tool changes, G43n for offset application, regardless of whether you're using a lathe or mill. Fanuc and others don't use M6/G43 on lathe controls, using instead a four digit T number where the first two digits correspond to geometry offsets and the second two digits correspond to the wear offsets:
T01xx selects tool one, applies X/Z offsets for tool one. Txx01 selects the wear offset register one. A nice explanation from Peter Smid can be found on page 104 of this book: http://books.google.com/books?id=JNnQ8r5merMC&printsec=frontcover&dq=cnc+programming+handbook+peter+smid&hl=en&sa=X&ei=GZqqT5S_NYO08ATUq-SgAw&ved=0CEoQ6AEwAA#v=onepage&q=cnc%20programming%20handbook%20peter%20smid&f=false In this paradigm, tool changes only require the Txxxx command to change tools and apply offsets- no M6 or G43 is required. I've thought about implementing this using M Haberler's g code remapping, but I would prefer to do it in the source if the changes would be accepted. On one hand, it would bring a more industry-accepted standard to LCNC lathes. On the other hand, it would represent a change to existing behavior. Any comments or direction are appreciated. Thanks!
