ABS calibration cube

thingiverse

In order to calibrate printing with ABS - when the wall are not easy to break and quality of them are decent you are in the right place with your settings. Settings I used: Hotend: 240C (JHead) Bed: 110C for a first layer, 90C for others, Bed was painted with ABS glue You should also notify two very important things: DO NOT use fan for ABS! Build a heat chamber (you can use cardbox even) this will improve the quality of your print and also provide good adhesion for the interlayers.
