FF Guider 3 Ultra g-code won't print past first layer

[Squid2Squid]

Howdy ya'll,

I've been experimenting with the Guider3U for about 2 months now, and I can't get past how crappy Flashprint is for slicing and printing compared to Bambu slicer. I use a P1P at home, so I was super happy to see the Guider3U get added to the list of supported printers in Orca. That being said, after a few days of testing, I can't get any Orca slices to print past the first layer.

In general it slices great, and I've figured out how to work with two materials in the software similarly to how Flashprint functions, but there must be an issue in the g-code which causes a consistent error on the Guider3U. I tried comparing g-codes, but I can't find anything with my limited experience editing g-codes. It starts normally, prints pretty well, but when it homes after the first layer finishes the error pops up. "Extruder not heating as expected" or something like that, and it freezes up the printer so I have to do a hard restart every time. I checked the thermistor on the nozzle and even tried switching it out just in case, but no dice. Could it have something to do with how Orca expects to use 1 nozzle with multiple filaments instead of 2 nozzles with separate filaments? I'm not sure, but I would love some answers.
