I was hoping someone could shed a little light on the tool compesation issue. I've read through the pdf file in turbo cnc but am still confused. I think the closest match is g54 -g59 for fixture offsets. Some other programs have a g42, I believe, for tool radius compensation tool left or tool right with a diameter variable. Could someone give a simple step -by-step on this issue. Also what is incremental mode? Maybe I need a copy of the RS-274D. any links to this?
