Hey everybody. I just built my very first printer, the Prusa i3 mk2s. The build was very fun and i managed to get perpendicular on my first calibration.
Here is an image of my first print. I’d love to know what ya’ll think, and any advice on how to make these prints better. Thank you very much.
Sorry about image quality. my camera is not macro friendly.
I notice there are two graps between outlines and the top surfaces. I am not sure about if the infill overlap needs to be bumped up or the extrusion multiplier needs to be put up a little or if you had a small problem with extrusion due to temperature or partial blockage.
@NathanielStenzel , I’d say to make sure pulleys are tightened, belts are snug, etc. I see piling on one side of letters, and gaps on the other side. On the back side of the placard, you notice the bubbles? That’s a sign of overextrusion, where the nozzle starts ripping up the previous line but then re-adheres a little further on.
@ThantiK ah. You spotted more than I did. I did not notice the piling of filament. I also did not realize that the over-extrusion causes that issue with the gaps for the bottom. Go figure. You have been at it longer than I have. I think overall, that first print was amazingly good. Thanks to your better assessment, @LogicalWaste will probably get some great prints. As for me, I need to work on my assessments if I am going to chime in.
Thank you both for your help.
Considering this print was done with everything set to default. Is there anything I can do without changing slicing settings?
Don’t get me wrong, I have no issues with that, but I’m trying to get a great print with everything set to default and using default STLs.
Anything on the hardware side I can do? I’ll check the pulleys and belts for sure.
My nozzle height was -440 when adjusted. Not sure if that says anything.
As @ThantiK said, check belts, pulleys, etc. I would probably do a wiggle test to find stuff that moves more than it should. He mentioned over-extrusion, so you could turn the extrusion ratio down 10% or less. My extrusion ratio is often 90-95%. That is about all I can say. My printer is a delta style and yours is cartesion style.
Just for my curiosity…which filament, what heated bed temperature, what hotend temperature, what was on your bed (if anything) for adhesion? I usually do strictly ABS with 90-100C bed and 220C hotend on Aquenet Ultra Hold. It is just interesting to compare notes on such things. I would say to clean off glue stick from a bed before applying hairspray. Just in case you try hairspray.
i just finished putting mine together yesterday, the calibration kept failing and all it said was check the manual, which pointed to make sure everything was assembled correctly (which it was) so i said screw it and started printing anyways, im in no way a professional at this but in my opinion the prints look great for a failed calibration lol, my nozzle height was at -333 after the live Z adjust, it kept printing in the air, and the silicon sock wouldnt let the filament extrude it was just balling up inside
@NathanielStenzel
I’m using mysterio3d filament. It came with the kit. They said to use the standard prusa Temps and settings, so I didn’t adjust anything. Just selected the gcode and let the printer heat to temp and do its thing.
I don’t know the Temps off hand. But basically standard Pla Temps I guess.
I didn’t use anything for adhesion. Just cleaned the bed and started the print.
Standard PLA temps are 215 for the extruder and 55 for the bed
I stared at that thing so long i memorized them lol
It lowers to 210 after the first layers then 205 towards the top
