  1. Hi, all. My Um was printing happily when I decided to work on some other print. I opened up my Cura 3.6.0 and immediately the printer stopped. Nozzle head resting right on the print, and the readout said "printing over USB". Which I wasn't, but ruined print anyway. So, I will leave the USB cable out from now on, but please UM, time to fix this bug. Here is someone else reporting related problem: best wishes, Maarten .
  2. With UM tough PLA I have to use 50% fan speed (or the part will sag) and 4mm retraction (or I get stringing) printing at 210C. Also, very helpful, before printing I forward some material. If the nozzle is a bit cool, or dirty, the material will not flow, and I frequently have grinding issues at the feeder. Makerbot also have a tough PLA, and it even comes with its own extruder featuring a stronger spring. What bothers me, is Ultimaker saying "... our Tough PLA offers the same safe and simple use as regular PLA." That is not the case, and it would be nice if UM would be more open about settings and problems associated with this materials.
  3. Thanks, ahoeben. I went back to 3.4 and I'll wait for next update. best regards, Maarten
  4. Hi, I found that editing the file name does not work anymore in 3.4.1. Gcode is named after the stl used in slicing, not the edited name. I am rolling back to 3.4 bst regards, Maarten
  5. Dear Brulti I have e printed for yours now, starting with a mendel I built myself, and with my old Tiertime Up Plus2 I had pretty much a hit print-ready experience. Though the prints were not nearly as good as what Ultimaker makes, and very limited in materials. But if I were prepared ti spend a lot of time tuning the printer and Cura settings and finishing prints, I could grab a Prusa clone from Gearbest for USD 300. But the UM is touted as a professional printer and priced accordingly. So yes, I do expect to be able to get my production going. Need these prints. regards, Maarten
  6. Thanks for your comment Geert_2, but I really dont think irt should be all that difficult. "Engineered to perform, the Ultimaker 2+ is reliable, efficient, and user-friendly. Thanks to its support of a wide range of materials, it’s suitable for a huge variety of applications, from prototypes to customized tools. " Thats what the Ultimaker saus in their website, and " Optimized for:PLA, ABS, CPE, CPE+, PC, Nylon, TPU 95A". So I expect to be able to du just that. And while I have lots of tools (including all the tools you recommend), I do not intend to spend a lot of time one what should have been a good print in the first time. I am having the printer looked at by a technician right now, I hope that will improve things. But frankly, if Ultimaker printers do not handle ABS well, they should be honest about it on their website. regards, Maarten
  7. Ok, I'll try to stay calm. I just spend €500 on an UM2 to 2+ upgrade, installed the latest Cura, put in a roll of official UM ABS and using the recommended settings. Frankly I bought this machine to print. Not to tinker endlessly with hundreds of settings. But I'll give it another try after 2 weeks of failing to print decently. I made a front/ top enclosure to keep the warmth in. I tried printing cooler and I get get poor layer adhesesion. This print is already way too weak for ABS. I think printing hotter may make support removal even more difficult. Can someone please tell me what I am doing wrong here? I'd be much obliged. Thanks, Maarten
  8. Hi BrandonH05, I understand Th ultimakers are not really supposed to print via Usb, you have to use an SD card, which I find rather medieval. Buy yourself one of these little card readers https://www.allekabels.nl/usb-kaartlezer/169/1286152/usb-2.0-kaartlezer.html?gclid=EAIaIQobChMIptHA04nR2wIVi6oYCh0RlAR0EAQYASABEgIe1fD_BwE . Much more reliable.
  9. @gr5 thanks, i will try that. Unfortunately C3 will not run on my pc. regards, Maarten
  10. Dear Community members, I installed Cura 2.3.1 (latest version that will run on a win32 pc). But I dont get to choose materials from the interface. This is what it looks like: however, in the install guide it looks like this: Am I missing something? I must add that my UM2 will not connect over USB, does that have anything to do with it? Hoping for your input, Maarten
