Title: Mach4 Lathe weird toolpath
Post by: RmaR on January 31, 2024, 12:26:25 PM

Hi all,


I'm trying to figure out the different Gcode command on a retrofitted EmcoTurn120. I'm trying to cut an internal profile as shown in the picture below. I wrote the Gcode below but I get very strange toolpaths when i run this on the lathe. It refuses to cut the arc's as I've designed them. It just takes of in the complete other direction. I've tried altering the G2/G3 commands, and changed the setting on the machine to absolute mode but I still can't get the proper toolpath. Any help on this problem is greatly appreciated!!

Thanks!
