Hello.
I just finished the build and the calibration. On the first
Print of the fan holder it started up good and after about 1 cm I saw layer separation. The hot end was at 230 seg and the bed at 90.
Al the part went out distorted.
Also I noticed that the extruder motor slip on the abs filament and "eats" it.

Can you please advise what to do?
Thanks

hey duvdev,

sounds to me like you're not printing hot enough. 230c should be hot enough to print ABS, but depends on a couple of things, including print speed.

I think the stock hot end is good to 240c, so you could try raising the temperature, or maybe slowing the print down a bit.

What are your print speeds?

Have you verified the Hotend temperature with a thermocouple?
Layer separation is usually a function of not printing hot enough for a strong layer bond.
