Comment on The Prusa Mk4 has done it again ☹️
ExtremeDullard@lemmy.sdf.org 4 days agoGrid infill is crossing, get a decent blob or buildup and you could have nozzle collision, I personally like gyroid but it is slower.
I’ve had the head collide into blob on solid infills (or perimeters) when the filament was too hot - usually TPU or TPE - but never infill. I’ll give gyroid a spin though.
prusa has an article for troubleshooting layer shifting
That’s a great article. Thanks!
I’ll go check everything tomorrow. The thing is, it’s the first time this happens (well, second time now). The only unusual thing I did compared to previous print was fill the bed to the brim, right up to the edges as allowed by PrusaSlicer. I’ve corrected that to make sure this isn’t the issue. Other than that, it’s a printer that’s been printing all day every day for a good year and a half. So yeah, it probably needs some TLC at some point…

Says a lot that it can run pretty much maintenance free for a year and a half! I only had issues with my mk3s doing daily enclosed abs prints in the summer, the original petg softened and it ended up killing the idler end of the x axis (idler mount deformed suddenly under tension after like… 1-2 months of that). They may not be the fastest or fanciest but they’re easy to service and in my experience pretty reliable, I repacked the linear bearings after a year or so out of precaution when I did a full rebuild, but I don’t expect needing to do that for a long time.
Here’s another prusa article for infill patterns, the prusa knowledge base is really decent and applicable to a variety of printers, I use my voron a lot but still refer to it.
