10 things I LOVE and HATE about the Prusa Mini 3D Printer 

Definitely a worthwhile mod! Thanks for the view!

bought the mini+ as a gift, saw this comment, and bought that extruder immediately, thanks for the headsup

Congrats! Happy I could offer some support and enjoy!!

Thanks for the feedback and support, I did misspeak when I said “all Prusa’s” as the mk3 and upcoming xl use direct drive, I meant all mini models, thank you. I stand by that this printer is louder than expected. These rails are greased, but all the movements and stops and vibrations are louder than other printers I’ve worked with thus the comment. And do you really think the coating on the heated bed is so thin than removing the bed with one hand and grazing it could wear it into a short circuit? That would be insane and a really poor design, thanks for the tip and feedback!

@@MrErdreich my friend killed his bed on their MK3 because they slid the steel sheet on the bed surface to put it on. Try to align it in air, and then snap the sheet onto the bed and it won’t happen

@@Fejszi wow who would have thought, thanks for the input and support!

Mine makes exactly the same noise I think it’s quite common. It also squeaks when you run PETG through it (because it rubs against the PETG extruder body when moving through it maybe) and the gears in the extruder click doing certain moves (I’ve tried disassembling the extruder and cleaning the pulley teeth, realigning the gears closer together to remove some slack and increasing temperature and changing the tension so I’m sure it’s just due to some slack still between the gears from manufacturing.

What do you mean by "anti vibration feet"?

@@YigalBZ there are designs you can find for your specific printer on sites like Printables. They dampen any vibrations that come from the different parts moving around and can significantly reduce the amount of noise in my experience.

There’s also these types of feet for big appliances, like washing machines, that are very cheap and designed for things much much bigger than a 3D printer, which work really well!

Happy to hear it, thanks for the view!

Congrats and no major worries! As mentioned, it really is an awesome printer! If you do get stuck, check out my unjam video and all of the resources provided by Prusa

I have, and it’s definitely more quiet. The comment in this video is less about how to fix the issue and more to point out that I found this printer to be louder than expected, and louder than my other ones under the same circumstances. Thanks for the suggestions!

My mini is super quiet as well

Not necessarily. These types of prints are typically done on a resin-type 3D printer (SLA/SLS) rather than an extension-type like this (FFF/FDM). If you’re exclusively making small high detail models, I’d recommend the resin type over any extrusion printer for better quality and precision. My preferred setup for ultra high detail prints with an extrusion type printer like this is a LulzBot Mini with the SL print head.

I did misspeak, thank you for the correction! I was thinking back to the old days :) I added a flag to correct my error, thanks again for the input and the view!

Sorry to hear of your challenges! In terms of your bed, I would heat the bed to 70 degrees, then wipe it rather aggressively with a mixture of water and isopropyl alcohol using a scotch brite / brillo pad. This should activate the TPU bed and make it more sticky, without needing glue or tape (assuming you have the metal TPU bed...if not, I suggest you order one). I would also check your filament idler pulley, which you can learn more about here: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-AJzafAzIYhM.html

I’ve heard mixed feedback from a lot of users. I’m not sure if it’s assembly variation or work environment, but my machine are abused by novices in a makerspace environment and typically get an insane amount of wear and tear. Even still, the Mini is a fantastic printer for the price point

rotary encoders do this when they are damaged. Mine does not do this. You probably have a damaged part.

Yep, I misspoke there and dropped a correction link to the Mk3. And agreed! The bond tech is a beast! Thanks for the feedback!

This is really helpful feedback and real-world input, thanks for sharing!

Why don't you print a support for the open end of the cantilevered 'arm'? That's gonna be my first print! Thanks for the info!

@@ragemodegaming7962 I’m not sure how you would do this? I have not seen this before but would be interested if there was some way!

Although I actually do see a Z-Axis Brace, maybe this would help a little
