0.25 nozzle keeps ketting clogged

mdelol — Tue, 02 Jun 2026 15:58:51 +0000

Hi!
I've recently got myself a 0.25mm nozzle and I'm experiencing clogs almost every time I try to print something.

Settings are correct - standard C1 0.25 mm with prusament PLA, 0.15mm layer height. But after 10 minutes to 1 hour of printing it clogs and stops printing (clicking sounds from extruder, no filament going out of the nozzle). Heating to 270 degrees and using the needle helps to remove the clog.
Any ideas what might be wrong?

Corner Issues

llankie — Tue, 02 Jun 2026 15:44:40 +0000

I'm having a weird issue with this print. The same corner always messes up. It looks like a mix of under and over extrusion. I also thought it might be a bed leveling issue, but I tried the print rotated 180 and also 270 degrees with the same issue. Then I thought it must be the model, but I cut just this section to isolate it for testing, and it printed WAY better. I've tried higher temps, lower temps, infill percentage, seam position, and scarf joint placement, with no change. Any ideas would be greatly appreciated.

For reference, this is in Overture PETG. I printed quite a few parts with the same spool that had no issue, one of them being almost identical to this with no issues.

Prerusene podavani filamentu, cvakani, zrejme heat creep

MH — Tue, 02 Jun 2026 13:45:21 +0000

Po chvíli tisku s filamentem Prusament PLA se filament přestane vytlačovat.Vytiskne se jen několik vrstev. Poté začne převodovka vydávat klapavé zvuky. Už jsem musel čistit vodicí kolečko a trysku (filament ztvrdl a zlomil se). Problém s podáváním filamentu se stále opakuje. Při montáži hotendu s tryskou se hotend pohybuje kolem osy (ne dolů); mohlo by to být také příčinou problému?

Core One extruder problem need help.

hello. I have reached a point with my problem that where I am just going in cycles with no solution in sight, I have searched a LOT and tried many things that i have been suggest in my search with no luck.

doing any extrusion it will on it skip/slip ( audible click ) and miss parts of the lining seen on the shell and fill. it can do the first layer fine, but anything past that and it will start skip/slip. can hear audible clicks when doing loading and unloading too. it started this after putting in a white filament but now its doing it with every filament. (picture provide at the bottom)
I have tried:
Cold pull x 2
idler screw tension
gearbox alignment calibration
removing and cleaning nozzle
printing without prusaconnect

I'm incredibly tired of this.

Filament not extruding and clicking

MH — Tue, 02 Jun 2026 11:37:26 +0000

After printing with Prusament PLA for a while, the filament stops extruding. Only a few layers are printed. Then the gearbox starts making a clicking noise.
I’ve had to clean the idler and nozzle before (the filament hardened and broke). The filament feeding issue keeps recurring.
When assembling the hotend with the nozzle, the hotend moves around the axis (not just down); could that also be the cause of the problem? Thanks

Is Anti-Aliasing (Micro-Non-Planar Printing) coming to the prusa slicer?

It seems like it works with the bambu slicer and orca slicer, but will it come to the prusa slicer too? It would make prints so much better

Nozzle Leaking, may have over tightened

Will Harris — Tue, 02 Jun 2026 08:32:31 +0000

My nozzle and heating unit has been slowly leaking. I think it started because I over tightened the nozzle when I put it back on.

But I lowered it the right amount the manual say and am still getting leaks. The manual mentions that over tightening could do damage to the heat break.

Is that likely what's happened here? Is there a fix for it?
