I have some long projects coming up for my CNC. Does the pause function work, or should I just power cycle the power when I want to stop and resume later?
I used the Pause function with CNC milling successfully - with GCode generated from Fusion 360.
I had an issue with laser jobs: Lightburn uses relative positioning, and the Pause-Function switches on resume to absolute positioning - this causes problems with such jobs. Perhaps make sure (by looking into the GCode) that the milling job uses absolute positioning. The GCode-command for absolute is G90, relative is G91.
Thanks for the heads up. This detail will really help me get jobs done.
How is the project recovery from power outages?
Huh, good question. I used power resume I guess once with a 3DP job - no idea if this also has a problem with absolute/relative positioning… My guess would be: it has. Reason: Both Pause/Resume and Power Loss resume do commands inbetween - Pause lifts the toolhead, and power loss resume does a homing and return to last known position - my gut feeling is that in these commands they issue a G90, without previously checking if G91 was the operation mode and not restoring the status.
