I don’t know what happened. Had a perfect print hozrs before. Cleaned the plate with hot water and dish soap. Didn’t change the settings. Then started new print overnight. This happened (picture 1) and the spool looks like this (picture 2). No clogging either. I did have a bad clog a couple weeks ago around the hotend cause the silicone thing ripped. The spool also unwound but I wound it up again. Cleaned everything and replaced the silicone thing. Printed fine a couple times and then this happened. Raising bed temp didn’t help. Adding a brim didn’t help either.
What could it be? Is my plate f*cked? Or the spool? The filament is dry.
looks like a small print. Try different spots. Can be the filament too, try manually increasing temps. Turn plate around, if possible, if same texture. I prefer alchool based wipes to dish soap to clean plates
Oh you’re right. It really is close. I cleaned the plate right before the print. But sometimes the thing its standing on (a Kallax from Ikea) gets a little shaky. Can that topple the print over or make the hotend hit the print?
If the wall prevented the spool from rotating then yes. I’m not sure that happened, as there seems to be just enough and the extruder pulls with quite a bit of force.
I’m sure the print came off the plate. Could be dirty, could be a draft (not often but possible with PLA). Just use hot water and soap without a lot of additives to clean it, dry with clean paper towel or cloth that is clean w/o fabric softener etc.
See that hole that is worn into the tap on the back of the plate where the nozzle cleans itself? I had that same issue and nothing would stick, I think that hole throws off the leveling, flip the plate to the new side, recalibrate it and you should be golden, that’s what worked for me in this same situation.
I cleaned my plate for first time with dish washing soap and just rinsed it under running water. When I next used the printer the filament failed to stick, the solution was to re-rinse the plate under running water, whilst scrubbing the surface with a nail brush. We do have a water softener and it can be difficult to get the soap residue off without a bit of physical help as well, but all is well now, but I have gone back to using IPA, it’s easier.
That’ll work well… until it suddenly doesn’t anymore. Once that happens, back to the water, dishwashing liquid and clean brush. With maybe a good dash of IPA before washing the plate.
The reason for gradually loosing adhesion when relying on IPA cleaning is that residue/oils/etc are frequently washed into the textured plates valleys where they gradually accumulate over printing and IPA only “cleaning” cycles.
Always spray and wipe with IPA, especially after washing with soap and water.
I have tested soap and water cleaning with and without the IPA wipe and I got much better adhesion with the final IPA wipe.
I would agree, IPA has definitely improved adhesion for me. TBH never cleaned with soap and water. But print failed, then IPA wipe and print didn’t fail has happened numerous times.
I use the 70% ipa junk from wal mart because it seems to work.
Sorry, but no. That wear is from cleaning the nozzle, it has no impact on leveling. What fixed your problem was probably the new side was, well, newer.
Depending on the plate this would be true. I won’t assume you know, but if you do apologies, never use IPA with plates like the Supertack or Biqu’s Frostbite and the like.
Soap and water will work fine for most provided you use soap without additives or a towel that has fabric softener used on it. These can (and often will) be left behind in traces that could affect your prints.
For PEI, Smooth and Engineering plates I will use plain dish soap and water then dry it off with paper towels. If any glue residue remains I will wash again or use a little 99 IPA. Again with new paper towels.
Supertack and the like it’s just water, usually a wet paper towel.
I have other plates that once in awhile I will use high grit sandpaper to roughen up the surface. Carbon fiber plate (not effects) an a PEX plate are the two.
As a loud propionate of “wash your plate” I often wonder if the hardness of people’s water is the reason that some people don’t see success with this method. Not all “tap” water is created equal.
