ABS Not Sticking to Bed

[danilius]

I failed. It did not warp but one end came off and went crunch crunch with the head until I stopped it

I was on 75 degrees on the bed and 240 degrees. I thought it was a bit hot and took it to 230 degrees and 10 seconds later one end came off. Reducing the temperature may not have caused it to come off?

Probably hard to do as it it fairly long and the sides are very thin.

You will want the bed at 110C once the print has started. I start with 75C then ramp up to 110C after the bottom layer in order to reduce waiting times for the bed to heat up. So that's your first problem. Nozzle temperature should not affect bed adhesion.

I got to .08" before it came off. The rest was stuck good and put the diluted PVA on the Kapton.

Was that a mis-type, and did you mean "diluted ABS"?
