  1. I am relieved to see I am not the only one having problems. A simple Online Shop or a link to a local/regional franchise stockist would be very useful to everyone.
  2. Why isn't there a simple link to an online shop for spare parts and other OEM bits & pieces? I'm having difficulty sourcing some replacement nozzles, that I'm confident will work with my machine (Ultimaker 2 plus).
  3. Thanks for your help. Unfortunately because I'm trying to create functional prototypes, it is important to me that I use a CPE material. Colorfab NGEN was recommended to me by the Ultimaker vender and has a good reputation. Howeve, following what you have said I have installed a brand new reel. I have improved the fragility and wall finish by running a finer layer height. I cannot get a decent part from a 0.4 nozzle and 0.15 layer height. Printing is slow but at least I'm not getting horribly fibrous parts that fall apart. Surface finish on a 'supported' face is still very poor and h
  4. I have owned my Ultimaker 2 for a few years now and have become very frustrated and disappointed. The parts I print are always very fragile with appalling surface finish. I can only assume there is something fundamentally wrong somewhere. At the moment I am using a 0.4 nozzle and NGEN Co-Polyester. Parts are fibrous and seem to have very poor layer adhesion. They crack & split apart. Also the exterior surface, except where bonded to the build plate, is like velcro. any detail is impossible. Can somebody help me get something at least half decent from this machine?
  5. "If you are printing 40 cubic mm per second you will indeed want the temp at 240C" So where did the example figure of 40mm^3/sec come from? Is that a spec of a 0.8mm nozzle? ".......try 0.3mm layer height, 0.8mm line width and 40mm/sec and 210C....." This implies a flow of around 10mm^3/sec. I'm assuming (from the temp) this would be using a 0.4mm nozzle. Is there an ideal printing volume flow (or range of) for each nozzle size and material? Would that be a good place to start from?
  6. I have reset my UM2+ to factory settings and copied the 'material.txt file then read it in Notepad. Apparently the nozzle temp for PLA through a 0.8 nozzle is factory set at 240C. Is this correct even though it's outside the range (200-230C) quoted on the Ultimaker branded material label? The temp. value I'm seeing in the UM2+ Materials Setting is a temperature value given immediately following the material name in the MATERIAL.TXT file and doesn't seem to have any relevance to anything. At least I have found where the nozzle temperature is driven from now. Thanks gr5,
  7. In Cura, at the top of the menu, there is a selection of materials. There are several PLAs listed (in the main list and in an 'Ultimaker' submenu list. My material carries the Ultimaker brand name so I selected the appropriate colour from the Ultimaker submenu. Written on the the spool is a temp recomendation of 200-230C. After installing the material on my UM2 and selecting PLA on the UM2 menu, it shows a temp setting of 210C. When I start to print the machine shows a nozzle temp of 240C. In the next fields, I have selected 0.8mm nozzle and 'Recomended'. With recomended selected you cann
  8. I'm having huge difficulties with my Ultimaker 2+. I have owned it for more than a year now and I'm still not able to get predictable or particularly satisfactory results from it. The combination of Cura settings and machine settings is a minefield of complexity. I cannot get a handle on where settings are being driven from. At the moment for example, no matter what I do, the machine insists on printing PLA at 240C with very messy results. Materials settings in the machine shows PLA at 210C but when I print something it 'strings' all over the place. If I then look in 'tune', it shows nozzle te
  9. Is this the only route to support for 3d printing with my Ultimaker? I've written a couple of questions/posts. When I hit submit it just disappears and I can't find it again. How do I get replies or responses? I've tried searching on my account name, but posts just seem to disappear.....What am I supposed to do? How do I get notified of replies?
  10. I am completely lost and cannot find any support. This website is a maze. I have written a post in the forum this morning to ask for some help. Now I cannot find any trace of the post and don't know if anyone has answered. If I try to login to the chatroom it just circles back to the login. I am becoming annoyed because I cannot find any support that this website writes so much about. Tojiero
  11. I'm having trouble printing parts of any real quality. I'm printing in NGEN with a 0.4 nozzle. My parts are coming out with a very rough surface finish with lots of fine whiskers hanging off. Printing time seems excessive, often being 5 or 6 hours. Also the parts produced are fragile and brittle. There are so many settings to be adjusted and I cannot find any coherent explanation of their effects and how I should work through them. I am finding this website extremely cluttered and the chatroom doesn't work, so I'm struggling to get any support. Can anybody help me out? All at sea Tojiero
