Prusa i3

[bubbasnow]

anyone build a prusa i3 yet?

We don't discuss such things on this Delta lovers forum!
Just kidding I like reading about all 3D printers, maybe we should open a sub-forum topic for Cartesian printers although I don't think the powers that be are going to do that.

[bubbasnow]

but the sell a frame on the site...

[bvandiepenbos]

I built a GRABER i3 version and a few guys in our makerspace have i3's also, they work fine, maybe not as as fast as a delta for some parts but they do make nice parts.
This is my version...

We also sell the PRUSA i3 flat plate style laser cut from melamine
http://www.tricklaser.com/Prusa-i3-wood ... -WOOD1.htm

These are the ones designed by Shane Graber (who is in our makerspace) based off of the i3
https://github.com/sgraber/Graber
I also helped Shane with a bit of the final design.
He did a great job redesigning the i3 to make it all laser cutable!

If anybody is interested I would send you my laser cutting file if you want to cut your own and/or hack and improve on it.

i was thinking this would be a better fit for the kracken/multi head printer

[Nylocke]

Never built an i3, or really seen a true i3, but Ive seen a MendelMax 2.0 which is based off of i3, and Ive worked on a couple i2s and an OrdBot, based off of the i3 as well. The OrdBots are pretty nice solid printers, not exactly my style though. I plan to build some incarnation of the TAZ eventually, thats as Prusa Mendel-y as I'm planning on going though. Ive got a bit of a list of printers I want... its a bit long....

That may be so, but I think we want to learn how to get the Kraken installed on the Rmax or Orion.
Putting it on the I3 is way beyond what this board is about. Your topic would better serve the forums that exist for the I3 or Cartesian printers.
I am not trying to act as an administrator of this forum on this, it is just my opinion. It is difficult enough to support the Deltas without throwing
the cartesian printers into the mix. Gene, your opinion please.

[mhackney]

Well, many of us have SeeMeCNC H-1 and H1-1 printers - their first models and both cartesian!

Plus, this is an "other" topic. No need to read if you are not interested. And, people working with foreign printers are probably not going to get a lot of help or information here but no reason to prevent them from posting. You never know what we might learn.

cheers,
Michael

Well considering this IS the "Other Machines" forum, I see zero issue with the discussion.

Besides, Cartesians give us something to feel superior to.

Point well taken Gene.

Another good point. Thanks.

[Nylocke]

And I and some others are guilty of talking about the ultimaker on the MAX forums....

Gene had a good point in that how can we know how superior the Max and Orion are if we don't have some crap to compare it against. (not an exact quote)
But the discussions about the "other machines" if you can call them machines, should be limited to this topic, not the Max topic. Michael also had a good point,
we may learn something.

[bubbasnow]

plus... i would still have to print the parts with my r_max... so it would technically be the i3's daddy... and mommy....

[Nylocke]

parent? Is there a term for a parent that is asexual?

[Eaglezsoar]

Don't tell anyone but I just started building a Prusa I3 8" from MakerFarm. Once it is done I'll send up some pictures and a review.
I will put it between my Rostock Max so they will have a look of superiority all day long. Actually I want to test quality of prints from
a Delta compared to a cartesion. It will be a couple of weeks before I'll send up pictures, this bum back of mine slows me down a
great deal.

[Polygonhell]

I have a couple of Cartesian printers and you can get comparable prints from either.
The crapshoot with most Cartesian designs is the Z screws, it's hard to buy straight screws, and the decoupling of motion from the drive screws is challenging, so you can build a printer that works really well, or get unlucky and spend weeks trying to I eliminate Z wobble.
The thing that impressed me most with the Delta was the layer alignment. I think I'd be tempted to use a belt driven Z if I were designing a printer today.

You just discribed my issues with my i3 build. I have had an i3 95% done for about a month now I haven't worked up the motivation to sort out the z-wobble. I did buy a pair of leadscrews only to find out that no one has made x-ends that incorperate ACME 1/4" leadscrew nuts (I also lack the skills to design a pair myself.)

[bubbasnow]

what about maker slide on the z?

[Eaglezsoar]

what about maker slide on the z?

That would probably work but not without extensive modifications. The Makerfarm Prusa I3 is 90% 1/4" plywood based and is not easily modified.
Designing an I3 from the ground up using the slides would be a great idea but incorporating them into an already designed kit would not be practical, that
would deter from the reason people buy the Makerfarm version and that is the cost. Mine is not yet complete so I can't say if I will experience the Z wobble.
If I do experience the wobble, as Polygonhell has mentioned, the challenge would be to decouple the motion of the Z screws without eliminating them entirely.
The cost benefits would be completely lost. I'll have to do some research, someone must have come up with something without replacing the screws.

Hey man, did you get the i3 to work? I am very curious as just ordered the laser cut parts from SeemeCNC and want to know what to expect before building.

By the way, I have a Printbot Simple and it is really good. I do expect to get something even better out of the i3.

Ahh ... for the records, I'm a proud owner of a Rostock Max as well

Thanks!

naw i havent started yet, i am waiting for parts to do dual extruder for rostock. then a cnc router/mill, then i will do a second printer >.<

Yes, my Prusa I3 is working but it was a complete kit from Makerfarm and the frame, etc. are radically different from the frame that you purchased.
I'm sure if you have a good set of instructions you can build the I3 without problems.
I have decided not to do a review of the printer and post pictures. This is a delta printer forum and I do not feel right getting that involved with cartesian printers on this forum.
If I ever decide to do a review, there are a lot of cartesian printer forums out there. Out of my respect for SeemeCNC who provide this forum, I just don't think it is right, discussing
these type of printers is one thing but reviews, pictures etc just do not belong here, in my humble opinion. Those who do not agree, well you also are entitled to an opinion.

I totally understand, and I meant no disrespect. As a matter of fact, I have only good things to say about SeeMeCNC crew.

However, I really think that lots of people would benefit by comparing what the differences are from cartesian printer and a Rostock Max. Myself did not understand quite well, and I wasn't easy to find valuable information in this regard.

That's why I build a cartesian, just for the sake of knowing first hand why a Delta is much better and in which ways. Now I understand a little more. However, still confused with all the different designs of Cartesians in the wild.

I think few people are really qualified to compare this two mayor approaches (Delta vs Cartesian), and I'm quite sure most of them are here, right in this forum.

Cheers!
