Hey,
I’ve got a weird issue.
Whenever I try to assign a filament to a nozzle I get a grouping error.
I’ve printed at least 24 hours pet-cf in the right nozzle, as it is loaded external to the right nozzle.
After the bambustudio update yesterday I cant assign pet-cf to a nozzle manually. It always gets automatically assigned to the left nozzle and when I try to change that - grouping error filament cannot be printed with right nozzle.
But I know it CAN ACTUALLY be printed, because I did so…for hours…
I know I could fiddle around and somehow feed it to the left nozzle, but I dont really want to rebuild my setup as everything has its order!
I tried to print hips as support…but that will only go to the left nozzle aswell…
Anyone here with the same problems?
It seems that there has always been this limitation for the high flow nozzle now its for both. thanks for nothing bambu…
This is due to the extreme brittleness of the filament just like PPA and PPS. The left hot end PTFE tube has a more gentle curve to prevent the filament snapping inside during print head movements.
thank you. Just strange that they introduce it after letting me print 500g right… still they could warn me but still let me do it my way 
Bambu has a cool system but sometimes they just block stuff even tho it has a relatively small error margin idk weird stuff.
Im pretty sure the PET-CF limitation to the left hot end was there from day one on the chart. Maybe they forgot to limit it in slicer until now.
You can use Support for PA/PET in the right hot end for supports.
