This section is under significant re-write.
Things can and will go wrong with even the most expensive 3D printer. It’s just the nature of the beast given the state of today’s concumer-grade print products. These pages are document a variety of common problems and hopefully will help with diagnosing and fixing the most common problem.
These notes are based on my experiences with 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.
Don’t forget Prusa support. One of the benefits of buying a Prusa is the excellent support. Log into the Prusa e-store and contact them via online chat for best results. Their support team is very good.
Prusa technical support is excellent, but you can speed things up by doing some preliminary work before contacting them. I suggest working through this list and at least being able to answer these questions ahead of time. It is also a good idea to have clear pictures of the steps you’ve taken and the results if possible. This will speed up the troubleshooting process and lessen the time you need to spend in chat.
