So I installed it last night... It looked pretty! but i wasn't getting enough pressure on the filament and the extrusion was super weak. Seems as if the filament wasn't been squeezed hard enough against the motor eventhough i've been adjusting that spring. Any ideas off the top of your head? I didn't spend that much time with it and as my profile says im a "newbie". I want to throw my ultimaker out the window lately so your feeder operation will have to be put on hold for the time being. :-|

Thanks! perfect! when i first printed the spacers they had caps... was a bit confused. So i set all the fill attributes to zero. And now i see what you mean by no heated bed too on the spacers (or else it squishes the end). I'll have this assembled in an hour or so! cant wait for no more black plastic in my prints! thanks man!

Hey robert- I agree with Nicolinux. I just printed your feeder design... a bit lost with your instructions. Just need a little more clarification. Specifically where the spacers and hub adapters go. :unsure:

Yo. I posted a similar question. Not sure if you know zbrush or any other modeling software, but I thought this was pretty interesting: http://www.3dprinterworld.com/article/mold3d-showcases-diy-supports-with-zbrush

Hey thanks LRobertl. Your "good print" way of thinking makes a lot of sense, especially as of late. So many variables that it'll make your head spin. No time to be an OCD perfectionist. In a few years when we are printing in climate controlled vacuums with no gravity I'll regret having spent so much time fighting this uphill battle. And I think adjusting the spring on the feeder helped already. Hopefully, I'll have some prints to show soon.

Hey for the first time after about 20 something prints I got my first perfect slip free base layer! You weren't kidding about the "tiny tiny bit". I stopped the print and tweaked the layer if the motor ever slipped. Eventually an 1/8th of a turn on the leveling screws made the difference. Thanks! let's see how long this lasts

Also! The tension screw on the feeder... I've found very little information on it. Tweaking that will affect motor slips on my first layer?

Thanks for replying so quickly, gr5. Nice to know that wretched sound (that kills my soul a lil everytime i hear it) is not bad for the printer. I think it's safe to say i just get most slipping on the first layer. On some prints pretty bad. It gets underextruded and rips up layers it had laid down. Right now I print my first layer at .2mm at 20mm/sec and at 230. The rest of the print at .09 at 40mm/sec. Print bed at 67. Ever since I moved .3mm to .2mm on the first layer it has helped a little bit. Those numbers sound good to you? If so, I imagine it's just really getting that bed leveling correct and then eventually building a better feeder and spool holder? I shouldn't have to readjust the bed after every 10 hour print? Thanks again. I know this stuff has been discussed hundreds of times...

Hi all- Quick question. Much like everyone else I am having under extrusion motor slipping issues. Especially on the first layer. :mad: I'm doing my best to fix it by getting a better leveling of the bed and printing thinner (for that first layer), hotter, and slower. Seems to work... Sometimes... My prints for the most part turn out pretty nice. But I wanted to ask how much motor slipping is too much motor slipping over the duration of a print? I don't think I can spot it as an issue in the print, but it still slips throughout occasionally. Is this something that is suppose to be avoided entirely? i.e. bad for the printer over a period of time? Or is the occasional slip (once a layer-ish) to be expected? Thanks guys! the community here is great.

Hey everyone- I am up and running with my UM2. Everything is good except for the motor slipping regularly :mad: But I'll try to figure how to fix that later on... I wanted to simply ask your techniques for building custom supports. I use curas auto supports, and while they work, I imagine building my own custom ones would yield a much better result. I've only stumbled upon this technique in zbrush, which definitely seems like a good idea: http://www.3dprinterworld.com/article/mold3d-showcases-diy-supports-with-zbrush But I was wondering if any of you have a specific way (shapes, coverage etc) of building your own supports? thanks.

Hello everyone- This is one of my first prints and one of the smallest. Since it is familiar, I wanted to run it by ya'll and see if this is what you would consider, "good quality". And if there is anything that pops out. http://imgur.com/a/FW0Gn I got it from 3dhub.com. It's their test print. I printed it twice. Once with automatic supports (which made me realize supports aren't always better) and a second time without. I believe the resolution was .08mm https://www.thingiverse.com/thing:215703 Thanks. The ultimaker 2 is awesome.
