Update: Let's talk about quality control for Prusa kits

As promised, here is my homing saga from issue 6 above. Apologies for the length. This is somehow the short version... From the very start, the printer had difficulty with the G28 (home all axes) command before each print and with homing calibration itself. It was tolerable at first, but it graduall

Is Prusa not offering the semi-assembled XL anymore?

About 6-8 years ago, I worked for a print farm running MK3s, and I built 4 or 5 of them for them in that time. Because even though Prusa was offering fully assembled printers, I made a decent wage assembling them and still came out less expensive building the kits. It was also an excellent education

Why Prusa upgraded the Core One but not the XL?

As a XL owner, im sad that they did not release a XL+ performance upgrade to fix issues and improve performance. Also I'm a little disappointed that it's so hard to track subtle improvements as there is no obvious revision list. I have tried to track the printable repository for printed parts and up

Taxa Temu alungă avioanele cu mărfuri de pe Otopeni la Budapesta

Da. la fel cum exista si laser engravers. La preturi cel putin duble chiar daca am considera aceleasi performante. Daca luam un a1 combo entry level de la bambulab -> https://eu.store.bambulab.com/products/a1?from=home_web_a1_detail e 370 euro acum. Eu am dat in jur de 450 acu ceva vreme, dar am mai p

MK3 upgrade kit to MK4S more expensive than entire new MK4S?

Actually imho the best way to ugrade the mk3s+ is using a Prusa Minis Buddyboard and Snake-Firmware from Github. Its called "mk3.3". It miss powerloss Recovery, MMU suport, NFC and crashdetection, but comes with a much lower price. The board itself is about 45€ at Prusa. The display, while about 100

First layer issue with Mk4S open since October 2024

I'm sure they're currently working on the fix, because such an "apparently "simple issue leaves their reputation in jeopardy and many customers are dissatisfied to the point of returning the printer. Now Prusa proudly shows the low number of printers returned by customers, but if people do in the en

Prusa XL USB Stick

My Mk4s kept freezing up mid-print. Sometimes it would only stop for 10 seconds or so, sometimes it would stop altogether. Worked with Prusa support for about a week troubleshooting, they couldn’t figure it out. Finally read on here about USB problems. I swapped out the original thumb drive with a S

Disappointing Core One Kit Experience

I had alignment problems with the outer frame as well. What worked for me was to loosen that entire corner. Align the frame and tighten them down. But seriously, that needs to be fixed. Should not have to deal with that. I have built a MK3S, MK4S x2, Original Enclosure x2, and MMU3 x2. Technically x
