Hi,
I don't know if anyone else has had this issue, I am using Cura 15, with a Ubis 13S hot end. I started getting really erratic hot end readings in Cura, variances of up to 20 degrees during printing. I ran a PID loop and got these results, this is with no filament.
I was going to input the PID settings as per the instructions on another post on the forum, but the KP value looks really low, does this look right to anyone? And are there any other issues I should be checking for?
