Thoughts about Raise3D, 3D printing and making in general.

I have been giving PC a go and have had success with simple things like a hook and a clip. However when I try something more complex that has supports and takes several hours to print, the part does not stick very well to the bed. i am getting some warping. I am using a temp of 260 for the nozzle and 80 for the bed. I am using polymaker pc plus. Have tried glue on glass and alos buildtak.
Polmaker Black PC MAX, i tried buildtak and it failed miserably the PC stuck to the buildtak but the buildtak adhesive pulled up from the glass. I printed a 12" x 12" x 3" telescope camera adapter on bare glass with purple glue stick and it worked great, i had the first print fail on the first layer. i stopped the print and raised the bed another .01mm (screw that sets Z home, left front corner of bed) and started again. Nozzle temp. at 270 c and bed at 110 c, and i slowed the print speed down to 40 mm/sec. also, if surface area that is in contact with the glass is small then i suggest you use helper disks. https://www.thingiverse.com/thing:346317 or something similar.
PC does not react well to printing fast, as it seems rubbery and acts like it has high surface tension while hot. IMHO, 40mm/sec is about the maximum speed for good prints - 30mm/sec is probably going to be more reliable.
