I've been having trouble printing ABS on my Robo3D. No problems getting it to stick to the heated bed, but my parts print very weak. It cracks and layers can easily be pulled apart. I've trying to do some research in order to get better prints with ABS but most posts explain how the extrusion heat needs to be closer to 250c. Now whenever i try to print anything higher than 230c-235c, my printer stops mid auto-leveling and loses its heat. I've read that the firmware has some sort of safety where if the heat goes over a certain degree it stops printing? I think.
Is there any way to get it to print at higher temps? To my understanding the Robo3D should be able to print with ABS but so far i've had no luck... I've messed around with most of the settings in order to get it to print ABS properly but no luck.
Next thing ill try to do is cover my printer while it prints to make sure the ABS cools down evenly through out, and change the infill overlap to about .2 - .25mm.
P.S. I'm currently trying to print with ABS on 235c extruder heat, and 80c for my heated bed. Fan is OFF. I lowered the Infill to about 25% but i really don't want to go any lower than that. Speed for printing is about 30 mm/s
