Printer is about to start it's print and hen decides to unload my entire roll of filament.
I just recently booted up my Creality Cr6SE again. I've been using Prusa slicer for some time now because I love the interface and updated features.
I've come across a rather odd issue. Every time I start a print, it goes through the start Gcode, draws the purge line, moves to the center of the bed to start printing, and then immediately raises, moves to the back right corner, and unloads my filament. If I don't manually reload the filament, it then returns to the middle of the print be to try sand start printing again. Once I load the filament back in, it works just like normal.
Thing's I've tried-
1. Adjusting my starting Gcode (listed below)
2. Removed my filament run out sensor to see if that was the issue (Problem persisted)
Thanks for any and all help you can provide!
G90 ; use absolute coordinates
M83 ; extruder relative mode
M109 S{first_layer_temperature[0]-50} ; set temporary nozzle temp to prevent oozing during homing
M190 S{first_layer_bed_temperature[0]} ; wait for bed temp to stabilize
M140 S{first_layer_bed_temperature[0]} ; set final bed temp
G28 ; home all axis

RE:
I'm not familiar with the Cr6SE, but this sounds like my experience on my Prusa when using the Manual MMU technique. I.e. I set multiple extruders and the tool change gcode is M600. Like that Prusaslicer likes to put a tool change right after the purge line. I've solved this by putting a conditional in the tool change gcode so it only puts an M600 in if the layer is greater than zero.
No idea if this helps you or not. Check your toolchange custom gcode in printer settings to make sure there isn't an M600 there, possibly leftover from previous experiments?

Well, you helped me fix a problem I didn't know I had! Haha. Woke up this morning and my printer was on pause. Started it again, ran for a little, and then paused again for an unknown reason. Turns out, I had accidentally added a color change at 2 specific layers. Appreciate the nod in the right direction!
Unfortunately that still doesn't solve my main issue of the printer unloading the filament before the print even begins
