I found a local supplier for the Magnalube-G that comes with the ultimaker. It does tend to build up a bit, but wiping it away and adding fresh grease has been smooth sailing.

I'm on my third cooling fan in about 4 months. Sadly these 75mm blower type fans seem to be all made in the same factory, and no matter which badge they have they are identical. (at least the ones on eBay). Anyone found a source for a quality replacement?

Just wanted to add my experiences with this issue. Everywhere I've spoken to in Aus. requires a minimum 50ft spool if they can get it in at all. $250 odd is a lot for a replacement. Maybe if there are a few of us who would like spares we could do a group buy?

I thought I'd share my experiences with some blue tape I've been trying. I've bought a few types from my local hardware place (Bunnings) to see how they go. So far the best by far has been scotch blue 2093 (edge lock) tape in a 2" width. After a few weeks of printing with various PLA colours I think I'll stick with it. The tape is smoother and thinner than the standard blue tape, so getting the first layer right is important. But the big advantage is the reuse of the tape, this tape lasts easily 7 or 8 prints before needing replacement. It's also easier to remove parts after printing, a good twist and most everything pops right off. I'm not sure, but it seems help parts from springing up at the edges while they cool also. Anyway, that's my experience, anyone else found some good tape?

Out of curiousity, it the steps per E value recorded in the GCODE? So if I load a .GCODE file sliced with Cura, would it print exactly the same as if I printed it over USB?

Hi Guys, I was printing at 60mm/sec and 215C. I dropped the temp a little and remeasured the filament diameter, all better now. Thanks all.

I've just done my first print with some blue filament and I'm trying to fine tune the temperature. The print looks great externally, but I noticed while it printed that the the infill was "droopy" while being laid down. I've got no blobbing and it doesn't seem like there is any overextrusion. I'm using Cura with a 25% infill. Do you think this is a symptom of too high a temp, or maybe just a characteristic of the filament? Cheers all!

Anyone happen to know what the correct fan header voltage is? I'm assuming that the electronics fan runs on 12VDC, can anyone confirm this?

Ok, after a little testing, the power supply is putting out 19.52V. The fan header is putting out 11.84V, so it looks like my fan has died. Anyone have a good source for a replacement?

Hi all, Just came across a strange problem. I added some belt tensioners to my x-axis belts, loosening and retightening the pulleys to make sure everything is perpendicular. Now when I turn on the machine, the electronics cooling fan doesn't run at all, and the x-axis stepper buzzes a couple of times then the whole thing is silent. My ulticontroller is still working ok through all of this and the blue LED on the thermocouple lights up, but there is no cooling fan so I don't want to risk running it. Going to test the fan header to see if there is voltage there, and run the fan off a supply to check it. What else should I check?

Just wondering what kind of ongoing regime for maintenance everyone is using? I've been checking belt tension, making sure there is enough grease on the rods and that none of the screws have worked loose etc. Would anyone like to share their routine for keeping things running smoothly?

Here is my first successful 90+ minute print, here is hoping it's not my last! It's a copy of http://www.thingiverse.com/thing:25357 , printed using Cura, 1.2mm wall and base thickness, PLA, 45mm/sec @210C. This machine sure gives great results when the bowden tube stays put!

Just wanted to add that I ordered my kit with an ulticontroller, so looking forward to you guys getting them too so we can compare notes. It's a really neat bit of kit.

Apologies for hijacking the thread and the double post. Just wanted to thank destroyer2012 for this advice, after many attempts this seems to have fixed the problem for me. Just got through my first 90 minute print with nice consistent extrusion. Best I can tell the issue is that the metal teeth on the white fitting need to be made to bite into the PFA bowden tube, the method above works great. To reiterate destroyer2012s post, as long as you have some pre-compression in the bowden tube between the PEEK and the white fitting with the blue clip, this holds the bowden tube in really snugly and prevents the tube from popping or sliding out. I hope this helps others in the same situation. Thanks again,

I'm having a similar issue with mine. Support sent me out a replacement bowden tube after the one that came with the kit was too tight to take filament. Since that, there have been plugs on 3 occasions and get the same sparse prints, see here: viewtopic.php?f=21&t=1036 Yesterday I took the hotend apart and replaced it with the spare one I ordered with my kit, I trimmed the bowden tube a little and made sure that it was all the way into the PEEK and I'm now hopeful that this has remedied the problem once and for all. Best of luck getting it sorted out.
