Has anyone figured out how to print Prusament Jet Black filament on their P1S? I’ve been printing Kingroon flawlessly, but I got a spool of Prusament Jet Black to try and its been nothing but a headache. Clumping on the nozzle, inconsistent infill pattern and stringing leading to balls of PETG clamps all over the plate. Random gaps from material not adhering to the surface (which is freshly cleaned). For the life of me I can’t figure this stuff out. I’ve gotten a simple circle button to print clean so I know its possible, but I can’t consistantly figure out whats going on with all the failure. I’ve attached an example of what I mean. I tried adjusting the temp to the suggested temps by Prusa (230 inital - 240 after) and slowing it down to the Silent speed even.
What was the result when you performed calibration using Orca Slicer? 
I agree with what he said☝️
PETG needs special attention when it comes to flawless printing.
I myself had an episode with sunlu filament which was totally my fault.
Your fan needs to do overtime. 100% minimum
Dry your filament.
Clean your build plate.
Calibrate your filament - start with a generic profile for your material, calibrate nozzle temperature, flow rate, and pressure advance.
Most problems will vanish.
I get flawless printing with my Kingroon PETG, getting a flawless result with PETG isn’t the problem. Getting it with Prusament specifically, is. At this point i run Kingroon exclusively because of this, but I had a free spool of Prusament so i tried it. Doesnt help it doesnt fit in the AMS either lol
Filament was dried in my Creality Space Pi + for 6+ hours at 65c.
Build plate was cleaned with Dawn dish soap.
Printer was calibrated, generic profile prints Kingroon PETG FLAWLESS. So my question would be if anyone knew those temps/flow rates/pressures for this specific filament or had a profile set up already printing it flawless. I’ve been using Prusas recommended temps, i dont think the problems are temps. It has to be related to perhaps a flow rate or something. I noticed sometimes when its doing the infill its not super clean, like when it does small quick extrusions. Strands sticking up or looking under extruded which prob leads to getting caught on the nozzle. I’ve printed a small circular button about the width of a finger nail flawless though, so theres def a setting to adjust i’m not figuring out. I’m half way through the spool at this point and prob will never get any again so I guess i was just hoping someone out there went through this with this particular filament and had a pre-built profile they could share.
This is a common mistake. Just because one filament printed well does not mean another filament will print as well. You got lucky with Kingroon because normally a non calibrated filament is a series of random settings when it comes to profiles that were not specific to that manufacturer.
I’m guessing that you hit the Bambu Studio Calibrate button and expected everything to work perfectly. That too is a common mistake. The calibration button on Bambu Studio is all but worthless as all it will do is the bare minimum which simply is not enough.
This is all random settings as far as the filament is concerned. As was stated above. First, ensure that the filament is dry. You can only ensure that by weighing it before and after drying it to ensure that moisture was present to begin with. If moisture was not present(as in, the filament spool did not lose weight after drying) then the diagnostics are different.
Second, calibrated the filament after drying using the Orca Slicer calibration routines. These are baked into the slicer.
Here are three videos that will walk you through this process.
