Walls are thinner than they should be (has printed fine a bazillion times), and layers are not sticking together.
What causes this?!
Is there a non-technical (motherboard, electrical, etc - too inexperienced to tackle those) way to fix this? I returned the one printer that was doing that. I never could get a good print out of it. I've started having the issue intermittently now on another printer (I have 3 of them - all CR-6 se). I'm scared of adding/changing parts, and I don't know how to calibrate my extruder.
Is it easy to fix? If so, how?
What causes this type of blobby/wavy line? This is the initial layer. Other layers do it, too, but sporadically. One entire layer might be like that, the next one fine. Or one area of an item be like that for one or more layers, other areas fine and smooth.
Any help appreciated.
This screw is loose. I can't tighten it, can't get it out - even with a magnet.
I started a smaller print job on printer #3. I noticed while watching it put down the first layer, that it was sort of "skipping" small areas and it sounded like there were air bubbles in the filament in the hot end.
Thinking it might be the filament feed, I checked that and found the screw loose (no jokes, please <g>). What to do to tighten this?
I just received my 3rd CR-6 se printer (obviously love them). My very first print printed brittle .... pieces broke off while printing. My other 2 printers work just fine.
My first thought, as I'd loaded a brand new reel of filament, was that it was bad filament. So I swapped it out for some that I'd been printing with, without issue. That was not it. Still brittle.
My 2nd thought was that it was the nozzle. I checked the nozzle on printer #1, and it was HUGE in comparison (and the filament that extruded when loading new filament was also much more diameter). So I thought "OK, this is a .25mm nozzle or something". But I'd bought a pack of .4 nozzles and compared them .... it was a .4 nozzle in printer #3. Somehow I'd received printer #1 with a larger diameter nozzle in it. I'm not even sure what the diameter is, but I'd guess it's at least .6, more likely 1.0. Sheesh! I've been using that nozzle on printer #1, with a CURA setting of .4mm nozzle. Printed great!
So I put the larger nozzle in printer #3 and tried again, still using what I knew to be good filament. Same result ..... brittle print.
So it's not the filament, it's not the nozzle.
What - machine specific - can cause items to print brittle? Is there a tweak I can make to the machine to fix it or do I have to return it?
Please help. I'll supply more information if requested. I'm still a relative newbie ... got my first printer in December 2020, 2nd one in Feb 2021, and 3rd one in March. First 2 work great. Beyond filament or nozzle, I'm clueless as to what to even look for.![0_1615818851256_20210315_103206.jpg](Uploading 4%)
I changed filament on my cr6se, and now the filament won't feed.
During the changeover, I must've hit the x-feed cable, because it had come out. I noticed when it wasn't moving (only the bed moved). I plugged that back in and "homed", that's fine now. But my filament won't feed. So I looked for another loose/unplugged thing. I didn't find any.
When I push the filament through, it works just fine. But the "feed" isn't working. Any suggestions?
