I can't print this timing pulley with Simplify3D. Cure worked no problem on the first print--not sure what is wrong. I slowed down to 40mm/s and stopped retraction at 0.2mm layer resolution. Same as cure, but the nozzle clogs before the print can finish-it curls up in the nozzle. You can see the filament in the picture. I have tried this about 5 times with different settings and the same thing happens. Any ideas on what is going wrong-I'm new to 3D printing.
I'm using a monoprice select mini with ABS, 235-240 C head; 65C bed.
