And the power panic resume didn't work :(. This was also my first try at manually changing filaments for multiple colors, waste of effort and filament lol.
Not a waste, just an investment in experience

Get a cheap APC battery backup, for a little over $100 you can get a 1000VA backup that'll keep your printer running for a few hours through an outage.
Ended up moving the little 500VA UPS from my computer to the 3D printer. Hopefully it'll help for brief blips.
What's your method for changing filaments. I've not had much luck with doing so
This model was set up for it already in the .3mf file. It stops, moves the toolhead over, automatically unloads the filament, and waits for me to yank it the rest of the way out then stick in another color. It then purges the nozzle a bit to get the main color fully flowing and asks you if it's correct before proceeding. I did this like 7 times for this stupid half-failed box lol.
Edit: Also, you can left-click the plus sign on the layer slider at any height you want after slicing in PrusaSlicer to add manual color changes in.
In prusaslicer, you can set a color change. Or you can edit gcode by hand with the m600 command iirc. But the second way is not recommended
I've done it once so far with good results. Setup a color change in Cura and then when that layer comes, the extruder moves to the corner where you unload and reload the filament and then purge it manually. Finally remove any stringing bits and resume the print immediately.
That printbed looks huge! What printer is that and how big is that bed?
I recently was dumb enough to tell Alexa to power off the smart plug of my printer. 5 hours into that print… While I was looking at it printing… huge brainfart… After that I looked into the void for 20mins thinking about how dumb I am…
This is just a regular-sized Prusa MK4, 250 x 210mm xy build area. I made this custom magnetic G10 sheet for printing PETG, it's 253.8 x 241mm.
Ah okay! Nice! Did you have to change something other than the bed to make use of its size (on the hardware)?
Nope, this is the same size as the stock Prusa sheets. The sheets are all a little bigger than the actual build area.
