Prusa repair — MK3, MK4 & Mini
Prusas are workhorses, but when a self-test fails, the extruder starts skipping, or the MMU won’t behave, the official answer is often a support ticket and a parts order you’re left to install yourself. If you’d rather hand it to someone local who’ll just fix it, that’s us.
Flat $60 to diagnose — bring the printer and we’ll pin down whether it’s a sensor, a worn part, or a setting, and quote the real fix before any work starts.

What to expect
Here's how it goes.
Bring the printer in and we'll run its self-test and a real print on the bench, read what the machine is telling us, and find the actual fault for the flat $60 — credited to the repair. Prusa publishes genuine parts for every revision, so we order exactly what your machine needs and quote it before any work starts. Most repairs are back with you in a day or two once parts are in hand.
Common questions
Common prusa repair questions
Prusa support is actually pretty good — why bring it to you?
It is good, and for some things we'll tell you to use it. But Prusa support ends with a diagnosis over chat and parts in the mail for you to install. If you'd rather not spend a weekend inside the extruder with tweezers and a wiring diagram, we do the whole job here: diagnose, order the right revision part, install, calibrate, and test-print before you pick it up.
My MK3/MK4 fails self-test or keeps skipping mid-print — what's likely wrong?
Self-test failures usually point at a specific axis, sensor, or the extruder, and skipping mid-print is often a worn drive gear, tension problem, partial clog, or a binding axis. The good news: Prusas are diagnosable machines that tell you a lot if you know how to listen. The $60 bench look pins it to the actual part, and you approve the fix before we touch anything.
Do you handle the MMU multi-material unit?
Yes — jams, filament-path trouble, and calibration on the MMU are all things we work on, and we'll test it together with the printer since the two misbehave as a pair. If your MMU problem turns out to be a settings-and-habits issue rather than a broken part, we'll show you that instead of selling you a repair.
Whatever broke, we’ve probably seen it. Let’s take a look.
We don’t price repairs over the phone — we look first, so the number’s real. The $60 to look comes right off your repair, and walk-ins are always welcome. Look for the blue door with the stairs on the left side of the parking lot — knock if it’s locked, we’re here.
