Overall im very pleased with my first print.

Overall im very pleased with my first print. My only complaint is all the little bumps on the front arms and the stomach. Would this be due to a lack of supports?

The zits don’t have to do with the lack of supports. It seems like over extrudion to me.
Try an extrusion multiplier of 95% and see if that makes any difference.

Ok. This is one of the files that came in the SD card for the Prusa i3 MK2S so i havent modified anything in it lol

Looks pretty good! Do a first layer height adjustment though!

Check this guide, it applies almost to any printer.
Hope this helps.

Yeah im brand new so all this is still alien to me lol

Would over extrusion also cause stringing? Because i can definitely see the filament retracting when it changes position.

@Cristian_Martinez it could but more likely than not you can just bump up the retraction a tiny bit to get rid of it. I assume you are using the Prusa research filament?

Yeah the 1Kg that came with it. Im on my 4th print and i still sit there amused lol

Add a bit more retraction in slic3r, and reduce your temperatures by 5 or 10 degrees to see if you can do the bridging without adding supports.

Wait how do i change that? Im still new at this lol

Ok but where do i find all these settings?

Go back in the manual for the printer and it will have a guide to adjust the first layer height. Prusa uses a different process than ‘normal’. Should be called live z adjust or something like that if I remember correctly.

Temperature can be an issue too, indeed.
Some people have mounted small fans directing fresh air toward the nozzle to reduce such artifacts.

@Adrian_Reef the MK2 has a high flow blower fan already. I think it’s possibly overextension/retracti n

Ok thanx guys :slight_smile:

@Panayiotis_Savva i dont have simplify3D thou, im using slic3r from the Prusa website

In slic3r you need to increase your retraction (look under printer settings, extruder 1, retraction length - just increase by .2 or .3 to test). Then under filament settings->filament change the first layer temperature to 210, and other layers to 205. slice it and export the gcode to the printer and print it.

@M_K11 ​ thanx man. Like i said im new at this im still figuring out what to do lol. But that printer is shooting prints out nonstop. I keep adding gCode files to the card and the printer cant keep up lol
