Hi folks, on facebook (and I seem to remember here also) there are a few users assuming that they suffer from heat creep, some (here a picture stolen from Facebook user Nand Maas) going to extreme measures: [grafik] I honestly doubt it. On the one hand, even the shown picture did not yield succe…

Like you say it, it sounds like there’s a recommended procedure to calibrate retractions - if so, what is it? And, for me still important to clarify, is if the feeder system of the DE has systematic issues. Even if admittedly the number of retractions in my failed print was high, it was still not e…

I too primarily use Cura because I like having it’s plugin features and more control over my print settings. I have never heard or read about a specifically recommended procedure for calibrating retraction, but I just run a retraction tower a couple of times, with one changing only retraction speed,…

DEFilamentCalibration01.stl (8.5 KB) DEFilamentCalibration02.stl (8.3 KB) These two parts are a model that I used to calibrate many retractions in a small amount of time. It helped me get very clean travels and minimal blobs and stringing. Though I’m still having the same issue of incorrect retrac…

[image] Spark: It always leads to the same issue of an expanded, hardened tip of filament, along with a nice grind against the strand of filament further up. The question is: What’s the cause, what’s the result? Is it that the filament expands/gets stuck and then the feeder starts grinding, o…

That is the very question that I am asking myself at this point. I have believed it to be that the clog happens first, and then the grinding happens. I haven’t considered it to be the other way around. I’ll have to play around with that idea. I thought 75C sounded very cold as well, but I took the …

It may have been heat creep after all - see in the new firmware: [image] Snapmaker 2.0 Firmware Updates and Downloads Controller Bug Fixes Fixed a bug that hotend fan had stopped unexpectedly in some scenario …interesting I’d say…

Very interesting. Here’s to the hope that this allows more wiggle room when it comes to making a working print profile for this DE! Updating later today!

Now I wonder if this was affecting the SE as well since they didn’t detail it.

Did a 5 hours print yesterday, kindof dual color: I had a thing with two parts, and against my habits printed both parts together, one in blue, one in black. Sliced in Cura, with the following retraction settings: [grafik] [grafik] Still had a bit of oozing, but all in all prints came out fine, a…

I just got my dual extruder and now I’m also fighting with expanded filament. Tried different temps, retraction settings, speeds but it always fails after 30-60min. I’m using Cura with profile from SnapmakerCuraPlugin 0.8.1. @Hauke settings did not work for me. Any ideas? Should I focus on retract…
