I generated the g-code from Solidworks Cam for a toy part and use LinuxCNC to simulate the milling process. The g-code generated from Solidworks Cam contains a line of "G80 Z44.5 M09" , which complained by LinuxCNC as an illegal operation - "Cannot use axis value with G80". I believe LinuxCNC g-code is based on Nist RS274NGS. I tried to change the machine to Mach III, FAUC11M etc. No luck!
Anybody has a clue how to fix it?
