A different multi-extrusion approach - UM tool / printhead changer

Wow, 3d printing has come on a bit since I last logged in a few months ago! Still leading the field foehnstrum i see! Great work -

Have you guys seen this: http://e3d-online.com/Titan-Extruder Could be a nice package for easy use with this changer system. Maybe swap for a pancake motor and would be sufficient? What do you think? -

Foehnsturm, any more updates on your machine? -
Idea about Quallity and dualextrusion compined Construction blueprint, design (UMO+).
macua85 replied to ABurkandt8519's topic in Modifications, third party add-ons & other hardware
It does seem here that you are trying to reinvent the wheel. The dual head changer system removes the second nozzle as a concern, and even takes care of any oozing issues as it oozes in the corner rather than on the print. Not sure why you would go through with this complex design, unless its just for the challenge,then go for it! We all like seeing new ideas here. -

Making your own Ultimaker - What not to buy on china stores (personal experience)
macua85 replied to neotko's topic in Ultimaker 3D printers
Cheers for the rod info neotko. Bearwood, yea i use robotdigg a lot as he is in China, and as I am at the moment, it makes shipping so cheap. I've just got my latest delivery...all the parts to make the 'mostly printed CNC machine'. I plan to use my plasma cutter torch with it. Should be an interesting project! Regarding the rods, it definitely pays to get from a reliable source off the bat, i'll upgrade to misumi in due course, once i've moved back. -

Very impressive prints there. Whats the next developments on this project for you foehnsturm? Have ultimaker given you a call yet to discuss a partnership!? -

I've just realised how out of true my rods are on my Chinese parts printer. I can see the twister blocks wobbling up and down on all axis when I move the print head. The prints all look good, but I'm assuming this affects the dimensional accuracy. So, don't buy rods from China! @neotko, how are the misumi rods? Do you have a link? Thanks -
Hey guys, I keep getting this rough surface on this part, always in the same places. Printed with colorfabb XT black on UMO at 250 degree. Thanks for any tips

Build Plates

I've got the same problem with the UM glass. I ordered a new one, but its got the same problem. Its weird, my Chinese heated bed glass on the other printer doesn't suffer from the same issue. -
Have you checked the belts (short belts) to make sure they are sufficiently tight? Also checked the pulleys to make sure they are nice and tight?

have to be honest, they didn't get tighter with oil. They were tight without though. Might just be that they needed wearing in....damn should have given them more time! -

I'm running those bushes on my Chinese parts built printer. No problem with them so far. They run smooth. One thing to note is that if you oil the shafts, the graphite in the bushes makes them turn black. No idea if you're not supposed to oil them, but I have, and they work fine. They are larger OD than ultimaker bearings though, 12mm. I modified the twister blocks on youmagine to take them. -

Labern, I disagree there. I've printed ninjaflex with great results. I printed pretty hot ~240, and slow. Also run the filament through an oil soaked sponge to lube it up for the bowden. It's an impressive filament. -

Quality is looking great, magnets seem to be holding the head well at those speeds too. Are you still using the same 2 magnet setup?
