  1. I never thought to just peel off the sheet. Can I reuse and reapply it after I'm done printing Nylon? I have one of those PEI sheets with the adhesive on the back. I'm on the Amazon page right now for it and it doesn't say if it's reusable after peeling the whole thing off.
  2. I use a bed adhesion sheet and no glue. That obviously didn't work for this. Do you think I should use the bed adhesion sheet with glue or flip it over and just use glass?
  3. Awesome! Just ordered from your store GR5. Thanks so much for all of this!!!!!!!!!!!!!!
  4. Hi everyone, Well I recently had a nylon print pull up on me overnight and get caught on the nozzle. Needless to say, it gummed up the entire print head where I had to buy a heat gun to pull off all the gobs of nylon. Yeah, big old mess, I won't forget this one. In the process of cleaning out, I accidentally broke the heating cartridge wire where it connects to the metal cylinder, after the metal crimp. I'm assuming there isn't a way to put that back on there easily so does anyone have recommendations on a replacement or what to do? Thanks so much in advance.
  5. Does anyone have recommendations on the Cura support material settings that affect the underside surfaces it touches? This is basic PLA on the .4 tip on .15 layer settings. I know that this surface won't be perfect but I know I can get it better than this. After a few YouTube videos, I've only played with the Support Z distance which was set at 0.2. I'm thinking maybe that's too much? Thank you in advance.
  6. Thanks. I hate having to pull this many levers in CURA and chase my tail while the customer waits. It's nice to have that sort of flexibility to do those things but I'd rather change the CAD and see. Any sort of ballpark dimension on what you think a gap should be? My instinct tells me maybe as a rule of thumb that twice the width of the tip you're using may be a place to start. We'll see if anyone else chimes in on this.
  7. Hi everyone, I'm running nylon for the first time and the default settings are working pretty good. Not sure if that plays into my question but, what is the minimum gap between parts or walls before they fuse together? Does this have anything to do with tip size as well? I have a ring type form that is not completely joined, which is part of the design. You're supposed to be able to pull it apart The gap right now is .006 in which is roughly .15 mm, I figured it would fuse. Anyone have a recommendation on this gap distance?
  8. Hi guys, yes there were a lot of steep overhangs so I ran the Z-Hop option and that helped tremendously. My printer is just over a year old so I didn't think the pulleys were out of whack. Thanks though for all of your suggestions.
  9. Yes, it's in both directions. So I suspect after watching a few videos that it bumped into some material and messed up the x/y calibration. I ran a smaller print after cleaning this all up and everything worked just fine. So now I'm doing the Z-hop option to ensure that this doesn't happen again. What is the axis alignment you speak of? Is this part of regular maintenance? I looked it up and I don't have that spacer tool they use although I could obviously print it.
  10. Hi! I've had good luck so far with my UM2+ in the last year that I have owned it. I rarely have problems but this has happened on occasion. I'm in the middle of a rather large 19 hour build on a .4mm tip and .15 mm layer height, the print has shifted in the X/Y dimension. You can see the layers printing a few inches diagonally off to the side. What would have caused this? Do I have a corrupt file? Or maybe did the tip catch on some plastic and it screwed up where it thinks it is? Thanks much in advance!
  11. Thanks guys. Xile6, where did you buy your hotend from? Yours looks different from mine with the spring setup inside.
  12. I may be late to the party with any discussion on this. Is there any commercial upgrade kit available, to turn a UM2+ into a dual extrusion machine? I haven't found anything but it seems like the print head is designed to take another heater block assembly. Thanks in advance.
  13. Tinkergnome is correct on those stats. Should I change anything to these settings or other settings? @SandervG
  14. Hi Sander. I've used the default travel speed of 120 and print speed of 50. I have retraction checked but I've never seen any customized settings for this. The stringing was actually worse but i grabbed a wad of it and threw it away before taking these photos.
