Got some problems with my anet. It has printed like a charm until yesterday. After a week stopped today i’ve got this ugly prints. It doesn’t matter layer size but It seems a little bit better with higher extruder temp. Actually settings: 210 degrees, 0.1 layer size, print speed 50mm. Any hints ?
clogged?
Hummmm… maybe. But if i push the wire manually if flow nicely.
make an extrusion test and see if the amount you expect is really extruded… could be a loos extruder gear or within the g-code.
Just to be sure i’m cleaning the noozle. I’ll male a test after cleaning.
Looks like the filament sprung out of the feeder mechanism - or loose extruder gear - had this too once.
@Ulrich_Baer or, the knurling on the Hobb Bolt may need cleaning. Or, your getting filament slippage form another source. Seen it, more than a few times.
same filament? maybe a wrong material?
Maybe you have your filament crossed in your real and it its intermittently getting knotted when trying to spool.
Filament was always the same. Now i’ve got a bigger problem. I could have killed the mainboard…-_-’ I’m waiting for the spare part.
Filament material? Moisture problem?
when I had a similar issue, it was a combination of needing to re-level the bed and a spool that wasn’t quite spinning freely
Ok. Printer back on track with a brand new motherboard, a brand new Mosfet driver for hot end (bed has already one). And a brand new noozle (even if the old one was clean). I’ve made one test again with taller layer height and all seems to work fine. Has to check better because i’ve printed only some layers and not a full model. But again when i switch to a 0.1 mm layer height i’ve got big underextrusion problem. First 3/4 layers are printed well and fine: brim is almost perfect and very tight as expected. Then comes the problems. Hot end is at right temperature during the whole print: set to 220 degrees and when the hot end fan start drop to 218/216 which i think is fine. I’ll try to increase the flow if i’ll find where CURA has this setting.
keep in mind that a low layer will increase extruder pressure exponentially. Make a 3 layer square - check the G-code in the End of that file you find the amount extruded (the last G1 E … <−) Now you measure your filament from extruder and mark that length. After your print the mark should be at the extruder (from where you measured) If Not you have to deal with a mechanical problem causing underextrusion — if this is exact you have to change the flow - maybe check filament ∅. The lower the layer the more likely that small errors become visible.
Ok. Maybe i had find where is the issue. I use 1.75mm filament. I’m pretty sure it was ok last time i’ve checked. I can only guess that last update has reset the value. I think this could lead Cura to calculate a wrong flow.
I would thanks all of you for the help. This evening i’ll try to see if that was the issue, in the meanwhile i’ve put a sticker onto the monitor “Always double check the printer configuration!”.
Ok guys. It was just the settings problem. I’m printing at 0.06 ad works fine.
