Hi
I've tried checking the box in the Edit/Application Preferences/Cam/Cam Export but after restarting Qcad and creating a new drawing the output is still IJK incremental.
Reading the post in the Trouble Shooting and Problems about Circles and CNC I am probably even less likely to figure out what I need to do to change over.
Is there another setting I need to change?
I am running Centos 7 and Qcad 3.18.1
Thanks
Jim

Re: How to switch to IJK absolute
You're likely looking at Edit > Application Preferences > CAM > CAM Import.
Everything to do with G-Code generation (CAM Export) is handled by the post processor.
To use absolute I/J coordinates, the codes for arcs have to be overridden in your post processor as follows:
Code: Select all
this.firstArcCWMove = "[N] G2 [X] [Y] [IA] [JA] [F]";
this.arcCWMove = "[N] G2 [X] [Y] [IA] [JA] [F]";
this.firstArcCCWMove = "[N] G3 [X] [Y] [IA] [JA] [F]";
this.arcCCWMove = "[N] G3 [X] [Y] [IA] [JA] [F]";
