I've been running my Anet A8 for the last 6 months with no real issues on the stock firmware. A couple days ago I tried out OctoPrint, and right away I'm getting really erratic temps on my extruder. Using PLA, with the target temp set to 200, I'm seeing spikes of up to 250 and down to 175, which is making the prints look like plastic soup. Is there something I'm missing in the setup? Thanks in advance!
