Troubleshooting prints

There’s no one panacea for problems, but “slowing down” linear speeds – whether in your slicer settings or using the front panel knob – does result in a lower volumetric rate, so can be a tremendous benefit if you’re having problems. Unfortunately, if you’ve sliced with really aggressive speeds (e.g. 170mm/s+ for infill), you may have to dial the front knob way back to help. Better would be to fix your slicer settings.


These notes apply to the Prusa i3 Mk3 printer. If you are using a different printer, please verify the hardware details are same. These pages may be a bit rough as I revise them and add new material. Please check back regularly for updates.

You can find me on the Prusa forums or Reddit where I lurk in many of the 3D printing-related subreddits.
