Having Problems With M600
Hi Gents. I was attempting to print one of the EVA 3 shrouds on my V-Minion, and in the slicer I used two M600 insertions to do color changes on two different layers. The first 6 layers or so would be black, followed by 3 layers of green, then the rest of the shroud is black. This allows the green background of the EVA logo to show through the front.
I tried this twice, and the print failed at the first color change each time. The first time, the first 6 layers completed in black, then the printer paused, parked the print head in front, and automatically ran the UNLOAD_FILAMENT macro to back out the black filament. I removed the black filament and inserted the green. I then manually extruded about 100mm of the green filament to purge the remaining black out of the nozzle. I then hit resume, and that's where things went south.
The print head crashed into the print and dislodged it from the bed, and crashed hard enough to bump the bed probe enough so that the Z-offset was changed. I cancelled the print and re-set the Z-offset.
I tried this again, and virtually the same thing happened, except the probe wasn't hit. However, the print wsa dislodged. I could also see that it attempted to start printing the green layer, and it was shifted in X by over 25 mm and wasn't in line with the previous location of the print at all.
What could be the reason here for why the M600 macro isn't working? Am I not doing the proper steps to change the filament? Is there a step I'm missing. Unfortunately, the proper procedure for how to use the M600 macro doesn't seem to be documented in the RatOS documentation.
Thanks in advance for any information.
