Hello, i am developing postprocessor for my customer for Emco VMC100 with Emcotronic TM02 controller. We have problem with helical motions with G2 G3. When there is Z changing in block with G2 G3 machine throws error 418 WRONG CENTER COORDINATE SPECIFIED. I checked the gcode and start and end points and I and J are ok. My question is to check if anyone have sucess to run helical motions on this machine and if you can share gcode example thank you in advanced.
