I have a Qidi Pro-X and I'm trying to print in ABS some rollers and each time they get to around 93% (about 90mm high) they fail. The plastic has burn marks and eventually the head pulls the part from the bed and its wasted. See pictures.
Does anyone have any thoughts on what is happening. Hot end temp tried between 135 and 150, bed temp although not the problem until the head hits the part is set at 90.
I've tried re-slicing at different setting and layer height, temperatures, speeds, and I've even made the part again and a little small thinking the height was the problem. Still happens.
