I was getting some weird top finishes lately with my H2D, just artifact lines and stuff like that. I though it might have just been print lift, but now I’m watching my video feed on my other monitor and the temp seems to be bouncing a lot more than I remember in the past. I’m printing PLA right now that is supposed to be at 220C. I’m watching it drop as low as 214c and overshoot as high as 226C. I recently installed an HF nozzle, it seemed like it printed fine for a while after installing it, and then developed the weird top finish… did I miss a step or something? BTW this is the right nozzle doing this. This printer probably has about 700hrs.
