Resume job from power down (CNC Issue)
-
Hiya - I've noticed an issue with resuming after a controlled power down. The spindle router tool, turns on too late and there is not enough time for the spindle to come to full speed before moving along cut toolpaths. It also does this after the spindle has plunged back into the material. Normally with CNC routers the tool turns on, comes to speed and then plunges into material. Even if it is plunging into an already existing cut line - coming to speed can rattle the tool against the edge of material and leave a noticeable mark. The spindle would best turn on during the resurrect-prologue.g or earlier in the resurrect.g file. I think deselecting the tool is causing this - T-1 P0 followed by T1 P6. Is there a way of changing this without having to manually update this every time it is needed?
I'm using RRF 3.4.0beta7+7.

@educatingsavvas I added a pause to my resume file for this. but you could maybe add a pause to the tpost file

@jay_s_uk I'm not sure what I've done now but the spindle is not turning on when M916 is sent. I actually think it only turned on previously after plunging because there happen to be an M3 command in the gcode being processed. So essentially resume from power loss doesn't work for CNC as the M3 R1 is missing.
I wonder if there needs to be different resurrect.g files for CNC, FFF and Laser modes. If there is a way of identify the line the job gets paused on, I guess we can write our own macros.
Possibly another thing for @dc42 to write on the list.

@educatingsavvas could be the case. I think the last job I ran was with beta 4 or 5
