Erratic Temps normal?

Post by Bobbystone »

Hey all,

Im trying my hand at printing some ABS. My first print didn't turn out too wel. It missed a lot of places in the perimeter for some reason. But the graph of my temps was very erratic? Is this normal?

Also, the extruder has a really hard time getting above 235C.

I had same problem, even that bad that firmware 0.92 generated error and stopped print.

I realized that it happened if head is moving (fast), without moving head it was OK.

So I checked cables and re-inserted & fastened the heater and thermristor. Since then my problem is gone.
