Anyone here build a Rostock to Kossel Printer?
Yes, I built a Rostock Max V2. Very happy with it.
I got a Kossel Clear from Blue Eagle Labs kickstarter project and except for the noise I like it a lot.
Thanks for the replies. Egon, would you say it is a lot noisier than a more conventional 3D printer like a Replicator or Ulitimaker?
I have it next to me on a desk that amplifies the sound so I'm not really objective. I did put dampers between the steppers and the frame but the main parts of the machine are made out of acrylic plates and everything is open, I don't think that is helping to reduce the noise. Most conventional printers have these boxes so I guess they are more quiet, but I'd have to pay more attention next time when I see one to tell you for sure.
I know you asked Egon, but I wanted to chime in. The noise is relative to where you place your printer (as in, wooden table = vibrations), and how you've built the printer. One of the upgrades I went with right off the bat was installing Astrosyn dampers (http://www.ebay.com/itm/331158026166...84.m1497.l2649) to the stepper motors... you can get an idea of how dramatic the difference is here: https://www.youtube.com/watch?v=_3Xn7b7tcxY
What type of dampers did you install? I wonder how the acrylic plates compare to the melamine of the Rostock Max. I think the melamine is one of the contributors of noise for me. Mine is also right next to me on my desk, and it does become pretty annoying. I notice that most of the noise comes from the vibrations from the desk, but that the printer itself (with dampers) is very quiet. I also noticed that once I assembled the top enclosure the noise increased a bit. The enclosure (asthetics) acts as an acoustic chamber.Quote:

This build will be on PLA printed parts that we did so maybe it will be quiet. Parts are all printed, extrusions and build plate are in, as are the carbon rods and build plate. Steppers on the way next week.
I cut some inner tubing of a tire into stepper shape, to dampen the sound a bit. I couldn't find the right dampeners at the time. Thanks for the link atoff, I might have to give those a try.
Your printed parts look real nice JohnA136, are those made to fit Open Beam? I'm thinking about replacing the acrylic parts with printed ones, also the roller cages.
Here are some pics of my build, maybe it helps you understand why:

I'm also planning to replace the acrylic arms with aluminium or carbon rods with magnetic ball joints on both sides, this will make it much easier to disassemble.
JohnA136, I designed a extruder for delta printers because I couldn't find one that had all the options that I wanted. It's made to hang from the top of the printer and has a filament holder to go with it, feel free to try it out:

Thanks for the pictures, they look great. We had some laser cut plastic pieces in our old Cupcakes but they always developed stress cracks? My son is assembling the frame this weekend, it is open frame with no HBP so it will be a PLA printer. Honestly, this is an experimental printer since we have not built a Delta yet so we are going low budget. It will be an interesting piece for our collections, I hope to have it at Maker Faire NY this September.
You are right, the acrylic looks nice but it's terrible fragile and I think also more noisy, could you post your source for the parts or did you design them yourself?Quote:

The build looks great, from looking at your pictures it seems like you will be able to print stuff at a height of about 40cm? Thanks for the info about those printed parts, I will look into it ;o)
It has been interesting so far, can't wait to see it completed.
Is that an automatic retractable Z probe i'm seeing in the last shot?Quote:

I don't want people to think that just because we are in the midst of a build, we stop printing cool things!

Sweet! Be careful with that lightsaber do ;o)Quote:

So it looks like time from printing parts, ordering stuff, building and printing is under two weeks. A little frustrating at times but now we can tweak things.
Happy Printing Everyone and Happy Mother's Day tomorrow!
Here is a picture of print number two. Seems to be working pretty good.

Nice, seems to run pretty smooth judging by the YouTube movie. The noise is about the same as mine I'm guessing...
Although I switch to Repertier and don't use auto calibration anymore (life is easier and I can do everything straight on the printer) I do find the probe system you used very nice!
Thinking the hole in the extruder drive gear might be a touch off center but it is printing. Here is a full shot of the printer.
ANOTHER KOSSEL BUILD! I don't know why every time my son builds a new project, I just have to go and do it too? :D

Looks great, I like the placement of the screen and other electronics on top.
Looks like Marlin on the screen, right? You might wanna give Repetier a go, I found it has some nice options for delta's ;o)
Thanks, since we spend a lot of time in class and at demonstrations where we are standing behind the bots, I thought the top mount might work out better.
It is Repetier, but I am having some issues getting the board set up. We use Marlin on our Prusa i3s but the Delta Printers fare better with Repetier.
Ah right I didn't recognise the screen, glad to know you came to the same conclusion.
It extrudes!stupid iPhone picture it sideways!
It prints

im thinking about a delta style printer, but was wondering...
if i wanted to make a taller printer, making it physically taller is just a matter of buying and installing longer components. but how would the machine know it has extra height now? i guess the same goes for a larger diameter... any help would be appreciated!
