Re: Mk3 Appears to have a serious design flaw and no Prusa response

Can you give a brief over view of what can be found in all those links? I have created wonderful prints with my machine, which makes me view a claim of "serious design flaw" dubiously.

michael.b67, is your printer signed by Prusa? Maybe that's why all you print is perfect. We're not that lucky here. A lot of printers are not signed. :(

Most links point to an number of threads about extruding issues, the first one points to a thread with a possible cause (idler gear wearing out it's housing and getting PETG dust into the filament path) and solution (redesigned idler with nylon washers).

What confuses me is a claim that this is a serious design flaw. You have MK3, print yourself a new idler - if you bought a kit the spares bag has a few nylon washers if not go buy some. It's like a 30min fix and you have all of the tools needed to perform it.

This is an amateur printer, with amateurish construction and performance, affordable to amateurs. Some things work great, some fail. Many people (including me) are OK with the price/performance ratio, which does not mean I like how everything goes. But if your life consists of something else than solely printing test cubes, chances are good that you get useful parts out of this printer.
But, hey, it's a free world! You don't like it - just get a pro printer with maintenance contract.

It would have been interesting to know what you consider as serious design flaws.

BTW IMO the feature that I miss most (by a large margin) is printing soluble support material, as this seriously limits the range of models I can print. I also see these extrusion issues, but for real life models they hardly have any impact for me.

This is a bizarre thread :lol:

:idea: Perhaps some people are just not meant to own 3d printers, and instead should consider being trolls.

Sometime I'm amazed when reading this forum.

Since I got my DIY MK3 in january I print almost every day with no particular issues, only done some improvements, printing mostly PETG, but also ABS, ASA, Flex, Carbon, the only problems at the begining was due to my lack of experience because it's my first 3D printer.

As a Linux user since 20 years, I'm very concerned by open source and it's one of the reason I choosed PRUSA.

No it's not perfect and could be improved, but you are free to make all changes, modifications you want, and no need to accept any licence agreement.

Come on, let's get real, If you are afraid of having potential issues and don't want to put your hands under the hood, just don't buy an open source printer.

So you are able to print flexible material without issues? My understanding is that flexible materials don't print well without modifications to the filament feed path, something I've been meaning to do as I want to print flexible filament.
