Hey guys, Any help trying to identify what is wrong with this one?
The first layer was pretty flawless except for the top-right side, where it looked kind of grainy. Maybe the plate needed cleaning on that side, but generally the adhesion is solid.
I was away while the second layer was printing, but apparently it failed and it looks like shit. When I got back, it was air-printing, still on the second layer as far as I can tell. However it seems like the nozzle was causing some of the artifacts to form, like maybe it was hitting the first layer or something? I am not sure.
This is on a Bambu A1 mini, with Bambu matte filaments. It is on a brand-new 0.2 nozzle, first print just out of the package. And the reason I got the nozzle was that I had some maybe similar failures before, where my previous nozzle seemed like was showing signs of clogging - i tried some cold and hot pulls, I could do some prints but some where failing so I thought to take this part out of the equation.
Any ideas what maybe could have caused something like this? The filament? I had tried drying it a while ago i believe, I can try again and I got a brand new one as well, but I wouldn't believe so because the first layer seems pretty good at the beginning. Could the plate maybe being dirty have caused buildup of crap on the nozzle and lead to a failure? Could it be something I can try maybe with the Z axis (although I have no experience with this? I did another calibration now though). I had read about AMS tubes as potential reason, but not sure how to tell. Any ideas what to check?
For reference I am trying to print something similar to this in different colors. I have already done 4 prints in other colors successfully.
I wouldn't bother with the filament width tolerance, you seem to have some serious stuff going on here. Maybe the 0.2mm nozzle just isn't made for this config, maybe the filament is bad somehow. I'd put in another roll and make a stupid calibration cube and go from there.
Before this, it was all okay?
I'll try the calibration cube you mention with the specific filament at high and low speed versus another filemant and try to compare the results...
