  1. Seems great. i am doing some prototyping with the UM2, but would love to have the double extrusion. Ide be willing to give it a shot!
  2. Hi This looks great. First question is, is this actually an automated, double nozzle solution? or is it more for situations where you pause the print, change filament, and continue? Ide love to collaborate with you if it's the former, as my goal is not to have multi-color prints, but to use water solvable material for the support structure.
  3. Thank you everyone, I have finally got the printer to work... Is there any real way to use UM2 with double extrusion? I see the board has the support and etc... but I wasn't able to find anything online that would confirm this can actually work. Is this possible to do? I would love to print with PVA as support material.
  4. would anyone know what size heating cartridge i need for UM2? would M4*15.8mm work?
  5. Thank you smithy. I have looked at that site and the parts are insanely expensive :(
  6. Hi everyone, So i have had my UM2 for a while now, and was very happy with it. Recently i had to change the PTFE , as i was getting a lot of extrusion issues all the sudden. In the process of trying to get back to printing, i ended up accidentally breaking off the temp sensor and heater element... on top of that the Coupler also broke when i was trying to remove the nozzle. Now i am looking everywhere for parts, and most part i see are for UM2+, but i have the original UM2. i am in the US and most of the parts I found ship from china which takes a long time, and I am not sure if i can trust them. I do not have a big budget, but i do need t get back to printing ASAP. I have seen many "upgrade kits" but i dont know if they are worth it? I just need simple parts, like the sensor, heater, and couple... possibly a new nozzle. (i dont mind upgrading the nozzle to olsson) Any suggestions on what to do and where to get parts fast at reasonable prices would be great. Should i upgrade the whole thing? or is there a place i can just get the parts i need quickly?
  7. Hi, I have an UM2, and looking for a laser attachment, mostly used for engraving anodized aluminum. Any ideas / suggestions? Thank you all in advance.
  8. Thank you guys... I just fixed my order but its now going to take untill the weekend or possibly later to receive it.. D you have any recommendations for good fillaments at a good price which also ships quickly within the US?
  9. Sorry for the stupid question i just researched it, and it looks like i need 2.85mm
  10. What size does it support? i was under the impression that it was 1.75 i just ordered a few rolls so ide need to change my order ASAP, please let me know what i should get for my Ultimaker 2
  11. Hi Im very new to this Just bought a used but in good shape UM2. I am using a PLA filament i had from my first purchase of a MakerBot which i ended up returning (the extruder never worked). I believe its also 1.75mm My prints are coming out very sponge-like. Even though all the settings are set for a very solid high resolution print (0.06 layers, 100% infill, slow speed and etc...) What am i doing wrong? I noticed increasing the temp from 210 to 230ish helped but far from being acceptable. (picture attached) Any ideas or suggestions would be appreciated.
