    Minimum Gap Distance

    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.

    Minimum Gap Distance

    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?

    Mid-Print X/Y Problem

    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.

    Mid-Print X/Y Problem

    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.
  5. 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!
  6. Thanks guys. Xile6, where did you buy your hotend from? Yours looks different from mine with the spring setup inside.
  7. 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.

    UM 2+ Stringing

    Bueller? Anyone?

    UM 2+ Stringing

    Tinkergnome is correct on those stats. Should I change anything to these settings or other settings? @SandervG

    UM 2+ Stringing

    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.

    UM 2+ Stringing

    Hi there everyone. What are some troubleshooting and settings you guys are using to reducing stringing? I've read a few things on it but didn't know if there was a definitive fix. Is this a common problem with the Ultimaker 2+? I've only noticed it when printing multiple parts with PLA with the .4 nozzle. I've lowered the tip temp down to 200 but that doesn't seem to be working that great. Other suggestions?

    Detailed Keychain Prints Not Working

    Just wanted to follow up with everyone's advice they've given me. It was a good exercise to try some new things here. I've found that the wood glue/water mixture works the best. The keychains turned out great. Also to use the brim feature when there's not a whole lot of surface area touching the bed, in the case of a ring model I just printed. The guy in the above video was all about scrunching the first layer and getting the tip very close to the bed. I tried his technique of tapping the bed during calibration and not using the card. Although all it did was smear material around the first layer and make a big ol' mess for me. It just didn't work for me on my machine but maybe it has worked for others.

    Detailed Keychain Prints Not Working

    Thanks guys. I'll try the hairspray trick along with washing the tray off with saltwater. Ever since I washed the bed off with tap water for the first time, I've been having trouble with it. So that may be the cause. Any specific brand or type of hairspray that works best?

    Detailed Keychain Prints Not Working

    Just the basic glue stick that came with the printer. I do notice it dries fast. Should I be using something else?
  15. I've got an Ultimaker 2+, running a .4 tip at .15 mm and using 3DUniverse PLA material. I'm trying to make 4 keychains in this build, they measure roughly 3.5 inches by 1.5 inches. Tried running this tonight and I had the material completely melted inside the tip and all around the heating core inside the extruder! Basically the print lifted up from the bed and got caught on the tip. After cleaning all of that out and starting on a fresh calibrated and cleaned bed, I watched it like a hawk. I brought the bed temp up to 65 degrees and slowed the print speed down to 95%. I'm still having issues though! I shut it down after it printed the brim so I could get some help from you guys. The letters aren't anything real fancy, just block text, but aren't printing that great. You'll also notice on the corners that the material is still lifting up and warping. Need some help and suggestions! Thank you in advance
