  1. No, I didn't use either of the betas. I just upgraded from Cura 14.1 I think.
  2. Yes, Yosemite 10.10.2 However, if you define a base folder then it works fine. This just may turn into a support issue for new users and upgraders.
  3. Same issue happens with me if no base folder is defined ahead of time. I'm not really into the replication idea for the files either, so that feature is kind of working against my traditional workflow at this point.
  4. Anyone have a good way of separating that white plastic clip at the end of the fan wires? It's like I need mouse fingers to do it. On another note, if I clip the wires, do I have to solder them together or can I just twist them and enclose them with a shrink wrap rubber sleeve?
  5. Unscrew the 4 top bolts on the head of the unit. The rest of the head should hang on with the cable connections. Just spin the head around and you will see two hex screws holding the fan on. You may even be able to reach them without unscrewing the top bolts.
  6. Use hairspray. Apply it on pretty thick, like glue. Works better when it is not all the way heated up.
  7. I've been printing with ABS really well, better than with PLA in fact. Just using the default temperatures. However, my best advice is to put down a heavy load of hairspray on the bed before it heats up. In fact, I have found the ABS to stick better when the hairspray is scratched up a little.
  8. netsrac- Is this the fan you found on Amazon? http://amzn.com/B004XCWXW4 Also, here is what my fan sounds like. My iPhone mic does not pick it up that well, but I can assure you that it's pretty loud. Registering over 60dB according to Decibel 10th app that I use on iPhone:
  9. Forgot to update this thread. I dismantled the entire fan shroud. The PLA was entirely caked on over just about everything. It took a while to heat up and scrape everything away, having to do it with a flathead screwdriver so I didn't burn myself. There is still some PLA in some nooks and crannies, but most everything is out. Anyway, the UM2 is working so much better now and that area has not gotten filled with plastic again. It was definitely affecting my prints before I cleaned the area out. I suspect that the bowden tube had come off from the nozzle at one point and PLA leaked through somehow. Now off to fix my extrusion problems with iRobertl's fixes. Printer has been working great except for these issues.
  10. Cool. I'll try it out, thanks gr5!
  11. I have a bunch of PLA that has built-up in the housing next to the nozzle. I'm not really sure when or how this happened. Could there be a hole in the nozzle? Anyone know how to get this out? I can print right now, but I'm not sure if it's creating an extrusion problem. Banooch
  12. Oh that picture is a great find. I had printed the cylinder myself and had the same problem as the pic at 70-degrees. Is it just me or does the 50-degree temp look the best as it has the least amount of warping at the bottom? Also, newb question here: do I need to press tune every time to adjust the hardware settings, or does the UM2 retain the settings from the last print, or do I just use the Tweak at Z plugin every time?
  13. I'm actually in San Jose, CA. Born in NYC though, so a fan of NY teams… thus the Yankee hat on my avatar! Have not made it to any 3D trade shows or fairs yet. Will try to get to one out here soon.
  14. Thanks so much for the clear instructions! I finally was able to get the PLA out, but only after removing both ends of the bowden tube. The feeder had crushed the PLA so much that it actually kept the PLA from coming out of the top hole of the feeder, no matter how hard I pulled on it. It wouldn't work in reverse either to get it out. I'll probably make a short video tutorial for other beginners so they can reference it. I imagine that this happens more often than not to people, especially with bad extrusions.
  15. OK, I can now confirm due to impatience that taking apart the feeder is NOT a good option EVER. Seriously, you need like 3-4 hands to put that thing back together. Although I did get lucky with just my two. OK, now I have to try the bowden tube method except that gr5 scared me with the "blades" comment. Seriously, does anyone have pics or video of doing this routine?
