I ordered some PC filament with 2 new UM3's and I went to load it using the UM3 menu and there is no option for PC. Better instructions for bed adhesion and loading instructions would be helpful.

    There's probably a way to create new materials on the um3 but I don't know how to do it yet. so instead pick the closest material - probably CPE/UPET. You want something within 25C of nozzle 260C bed 80C. So ABS would work also. Then do:

    SYSTE->build plate->set temp and set the buildplate to 80C. Go away for 10 minutes and come back when build plate is at temperature. You really can't do the next step until build plate is at temperature I beleive. Putting a cloth or towel or rag on the glass will speed up this step.

    Now do PRINT and start your print. Wait for all the motors to stop moving around and go into the TUNE menu and adjust the build plate temp to be 80 (-20C from ABS?).

    Now maybe exit and re-enter the menu and if the build plate is within about 3C of goal temp it should start heating the nozzles. Go to the nozzle with PC max and make sure the goal temperature is not 0C. Once it is the ABS (or other) goal temperature, do the same adjustment. Once you do all this exit the TUNE menu and it should just work.

    This *will* get easier in the furture when someome explains the "right" way to add materials to your printer.

    By the way if you print 2 materials you typically want to go with a build plate temp best for the cooler setting. If you go 80C bed with PVA, the PVA will melt or at least be too soft.

    Actually I think you can simplify if you know in advance the goal temps for nozzle and bed and make a note of that and figure out the offset temperatures to get to PC MAX.
