What is the max temp setup for in your firmware? If its close to what your heating too it will trip it everytime.
If you heating to 215c and the limit is 220c then you will fail everytime. I have my max setup to be about 50c more than my ABS temps of 240c.
If the axis is slow then speed it up in the firmware. Too fast and the motors will stall and scream at you. Also keep the acceleration down on the Z axis so it doesnt mess up.
Have you calibrated your Z axis yet? If you tell it to move 10mm up does it indeed move 10mm?
