Is anyone else having HORRIBLE problems with their Prusa Mk4 or Mk4S first layer quality…

My mk4s developed a problem that Prusa spent 3 months troubleshooting with me where the first layer is being laid down too close, and so filament blobs, then prints fail.

Eventually, they advance replaced my whole printer, and the new one had the exact same problem out of the box…

I managed to find a bug that was raised on github for this exact issue, with 22 other people registering “mee too” for the issue…

I’m just looking for some feedback from the wider community to see if any others have hit this problem?

    Isn’t their entire FW closed and using proprietary boards? AFAIK replacement parts are also only available as STLs? That’s somewhat halfhearted open source IMO.

        No, I believe you hold Prusa to a higher standard than they actually deliver. It’s true their roots are in open source, but these days they are only partially open source and their control board is not open source at all.

      It’s true it could be better. They used to be more open source. Like they used to just publish their firmware source as they released it. Now days they hold back the current generation till the next gen is out. They mentioned this was so they could be more competitive with companies that do less R&D and more cloning.

      Like even their slicer was just reskinned etc. it’s in peoples rights to reskin an open source slicer but I see why they did it.

      Maybe “was” is the better word. Still better than things like Bamboo though.
