Might cancel order and get the MK2S  

Re: Might cancel order and get the MK2S

If it's firmware, then everyone would be having issues. Many are not having issues (including myself), so my take is the firmware is mostly good.

Everyone IS having issues, just browse the forum, other forums, youtube- hundreds of people have issues.

Everyone IS NOT having issues. How many MK3 kits/assembled printers have been sold/shipped? Over 5,000 shipped from what I read some place. I haven't seen over 5,000 different users complaining about the same issues. From the prints that I have printed so far on my MK3 the quality is approximately the same as the 2 MK2S that I have. Am I the only person that hasn't had issues? I doubt it. The people that don't have issues generally don't come to the forums, and if they do come here, they generally just read the forums and don't respond.

I finished a 45 hour print the other night, using really cheap PLA ($14 KG). Were there some defects, yes, but that was due to the pre-processing I had to do to it because of the ultra thin walls on certain pieces, and loose pieces (drawing was made for manufacturing not 3d printing) and due to some of the support structure.

Note: my MK3 was prebuilt by PRUSA, received it mid-Feb. I have not done any fine tuning to it - no Z adjust, no flow adjustments, etc. Straight out of the box. I ran prints with the original firmware that came with it and then upgrade to the latest firmware.

"I'm not having issues and I didn't do my research so therefore nobody else is"

Just because you're doing fine doesn't write off all the others having problems, many youtubers involved heavily in the 3D printing community have stated how buggy and messed up the printer is, prototype or not, it wasn't ready.

Still, here's hoping i can get mine fixed.

Re: Might cancel order and get the MK2S

For those arguing that Prusa is supposed to push boundaries and be for enthusiasts - that's not what they say, check Page 3 of the Printing handbook you got with the printer (emphasis mine):

"In addition to printer hardware upgrades, the main goal is to make the technology more accessible and understandable to all users."

More accessible and understandable means easier to use, more reliable and with a lower level of technical knowledge needed. Less fiddling with the printer and more printing.

Currently my Mk3 is working, but I have had no less than 5 separate visits from the UPS guys bringing me replacement parts from Prusa, bringing me a different item each time. I am sick and tired of rebuilding it.

I no longer ask myself "will my Mk3 fail?", but "will it fail this week... or next week?"

This right here-

I am steadily learning much about this machine, and perhaps over time i can make it work with the help of the more knowledgeable people out there, however the machine is advertised as being "easy to use and ready to print out of the box" which is why I bought it in the first place, and thus far that has been the exact opposite of my experience.

Again- i hope I can get it functioning optimally in the near future, but with all I've recently come to realize; I can't help but feel a little deceived by a company that advertises one thing, when later I find out its followers advertise something else.

There you go again... over stating things and assuming things. Where did I say that I'm writing off the problems that others are having? Just like your statement that "EVERYBODY is having problems". I don't see EVERYBODY having problems. I don't see the 5000+ owners of the MK3s in here or other sites complaining of issues. Are people having issues yes. Is EVERYBODY having issues - no, Are the majority of MK3 owners having issues? I don't think so from what I have seen.

Okay- "A-LOT" of people are having issues.

Seems like instead of trying to help you're just looking for a fight, so until you prove otherwise i will not reply to you further, and i apologize if I got on your bad side simply because me and many others are looking for help.

Re: Might cancel order and get the MK2S

If you want a really good printer right now I’d avoid the MK3 and get a MK2 with the 2.5 upgrade. The mk3 is still good but it does have issues and the print quality isn’t were it should be, that doesn’t mean It won’t be as good in the future. Everyone has an opinion, only you can decide. Mk2s is a proven printer

You won't see 5000 people here. 1% at best who have problems will even come here or some will just read/watch and never post. (general rule unless they all catch fire simultaneously). you'll see others on facebook groups etc... only way to know is support requests or ask each one of them, anecdotal evidence doesn't mean anything and even if 20% have issues that's still an problem. for some it's their first machine so they have nothing to compare against. people might not contact them on print quality either, just pure failures or partial failure. i've seen posts of images that say "got my settings dialed in" and all i see is vertical lines all over the print and they think it's great.

There are definitely some QA issues that keeps results less consistent across machines someplace. surely they're working on it, they are hiring more people. the mk2s was the first machine my kid could even use... load model with slicer preset, pop in the SD and hit print. it stuck to the bed, it finished and it looked pretty good.

The initial release had issues, over extrusion, skipped/shifted layers in prints, filament sensor false positives. Broken octoprint and still there is no linear advance (in 3.2 whenever that comes). Since some of those were fixed, you can't say they weren't issues because there were tons of people complaining about them but it was still 1% of the actual people who owned one. it still needed to be fixed either way.

i've heard already some that have problems after upgrading to mk2.5 which could just be user issues but given it's the same firmware base now, it could all be firmware.

Re: Might cancel order and get the MK2S

I had a MK2S and exchanged it for a MK3. I had plenty of problems with both models. MK3 still has some nasty issues with PINDA and calibration, but overall, the machine works fine for me and I mostly get beautiful prints out of it.
For me, the silent Trinamic drivers and the magnetic bed are killer features - I'd never go back to the MK2S.
If you look close enough, you'll find many problems; more with the MK3 as the software is still in beta state. I'd say take it easy, let Prusa do their job and in a year or so we'll have most bugs sorted out. Some will be fixed in software, some with hardware upgrades (MK3S?) and some will be learnings for the MK4 (where we start again from scratch). In the meantime the MK3 is still a decent printer. If you look for perfection go elsewhere (and expect price tag times 20 upwards).

Re: Might cancel order and get the MK2S

I received my MK3 yesterday. It was a pre-built unit and I could not be happier. just did the Z calibration and started printing with excellent results. This is my second printer so I have some experience. I printed a tree frog and the batman logo... additionally I used prusa control and slic3r PE and had to problems with the supplied PLA.

first layer was perfect and super smooth. I'll try ABS tonight but I was honestly worried seeing a lot of the comments and I feel for the people having issues.

FYI ordered Feb 8, received March 28

just my .02

Starting to look like a lot of people who ordered around November to December (like me) are the ones having the most issues.

Re: Might cancel order and get the MK2S

no objective data to prove it but I would say it appears that if the mk3 is your first printer you may be more like to find / have issues.

This is my second large time upgrade the the anet type clone kit I bought for 220 us on amazon. mine is kit what I learned from the anet was a big help in the care and tlc i put into the build. Took the better part of a week. made it look just like the picture.

I love this little hot rod, its got a lot of head room for change.
