Prusa Research

Hello folks! Build a MK4 4 months ago and was very happy with it so far. Now I have bed adhesion problems (see pic attached). 3 weeks ago I had similar problems and after a chat with prusa and resetting the calibration / cleaning the build plate again it worked fine. Now the problem is back despite a clean build plate . After resetting the calibration I got one nice print and then the same problem again. Cold pull of the nozzle resulted in a clean tip and no better results, so I do not think there is any clogging. Also the plate and the should be alright, as I got good results inbetween. Any ideas / hints where my problem is? Link leads to image of the problem. Could not upload the file for some reason...

Hey !prusa, maybe you can help me. I have a self-assembled Mk3s+ that I put together about a year ago, but never really used because of the following problem.

If I print on draft quality, it makes it through most prints. I've printed a dozen cubes, several brackets, and some other odds and ends.

If I try to print on higher detail settings, however, it behaves very strangely. Most often it'll just hang, and keep oozing out more plastic. Once in a while, the steppers will keep turning and ram the bed or print head against the ends of their tracks.

I've tried updating and downgrading the firmware, different SD cards, etc. to no avail. Support hasn't been much help either.

Any ideas?

As you can see in the video I insert a filament and keep pressing „purge more“ but nothing comes out until I push the filament from the top with my fingers (and afterwards purging works as intended without additional intervention). The filament in the video is Fiberlogy Fiberflex 40D. I never had such issues with this filament on my MK3S+. Does anyone have similar experience? I already tightened the idler screws by 4 turns, but it looks like the plastic part of idler just rests against the metal Nextruder frame. Maybe I should redesign the idler, so the small pulleys can reside closer to the filament feeding gear…

I recently had a conversation with a colleague about #opensourcehardware and exploitation. I mentioned the recent @prusa post.

Today I learned of how Miniware has similarly exploited work by the community around the @PINE64 #pinecil in the development of their TS101. It seems Miniware is refusing to release schematics or code: https://github.com/Ralim/IronOS/discussions/1664#discussioncomment-5680597

I haven't investigated this further. Are things as they seem?

Why don't we treat these companies and products like the bad actors they are?

In case you use cotton pads for wiping the build plate with IPA and you own an Original Prusa Enclosure you may find this model handy

I wasn't aware of some of these. The measurement tool is a great addition.

Prusa XL Dual Extruder Setup.

First look at the Prisa XL dual toolhead.

Here's the github release for those so inclined

Mk 4 Kits shipping
Began shipping semi-assembled single toolhead XLs
first dual-head models in the week of June 19th
MMU3 for mk3s in the end of June
mmu3 for mk4 end of august

Hi there, I've been having a little trouble printing models with my MINI+, when there is very low extrusion between retractions. The Extruder grinds the filament through, and then the filament in the hotend burns until it gets stuck as well.

It usually only happens when I print extremely fine things like DnD (2") miniatures at .05mm layer height.
For now I've switched to .15mm layer height and have not had the issues since, but I wonder if there's something that could be done, except changing the Extruder/Hotend?
