We recently purchased a TAZ 4 printer, but have been running into a number of issues. Initially we ran into a few hiccups, namely the nozzle wasn’t assembled properly and clogged, the firmware was corrupt and needed to be re-flashed, and the axes were a little loose/wobbly.
Even after fixing all these issues, however, we are still unable to get usable prints due to corners curling up and general ABS warping. We have tried a number of different fixes: re-zeroed the hot end, re-leveled the bed, tried various bed temps ranging from 90-110C, tried using a brim, used various adhesion layers ranging from hairspray on glass to Kapton/abs slurry to PEI, created an enclosure to eliminate possible drafts, even used a thermocouple and heat lamp to keep the inside area at a constant 38C. What is the most confusing to me is that my coworker has the exact same printer sitting on his coffee table in front of a partially open window and it prints the exact same Gcode with no issues and no special adhesion layers.
We are really unsure what to look for in terms of why this printer isn’t working properly, so any advice would be greatly appreciated.
