Re: extruder temperature dips

I noticed the same kind of temp graph on my heater bed some time ago. It turns out that a wire was failing between the print head and the controller board. The continuous flexing caused one of the wires to finally break from fatigue. What you may be seeing, as I did, is the connection being broken a...

Re: Raspberry Pi & Octoprint Performance Check

I have the latest Pi on my Mini with a Logitec camera. I am very satisfied with the response. File transfers are fast, and the video is maybe just a little bit jumpy, but acceptable. It's not as good as with a dedicated webcam, but certainly acceptable to me. It is hardwired into my local network, n...
