hello need some help just converted my lathe to cnc im using bobcad lathe as cam the problem im having is any radiuses on my part seem to be backwards instead of arcing to make the raius it gouges into the part if that makes sence kinda foloeing the rong derection of a circle instead of cutting lets say twenty or so degrees of a arck it cuts the remander 340 degrees hope that makes sence
oh ya one more thing in bobcad the toolpath is correct it follows the radius corectly but when loading the code into mach the tool path showes it cutting the other side of the arc
the line of code that seems to be the problem is
G03 X.24 Z-.034 K-.066 I-.0829 F5

Try changing the mode ie; from incremental to absolute or the reverse.
See the first few pages in Mach3 Turn-Arc Motion write up which can be found in Member's Doc's.
Post the file.

Check IF you are using front or rear toolholder based arcs.
