I've had a similar thing with ninjaflex. I found by moving the knurled nut further in on the shaft (about 2-3mm so the textured part was more central to the filament) stopped the filament from slipping off

I suppose the good thing with the above design is its modular so you could stack up a couple, but then my concern would be the stability of the printer. I do have another design for an enclosure which would allow multiple rails for storage and should be able to be put together with hand tools. Once I have bashed the design out I will put up a thread in this section Like everything its never simple, but in all fairness I do enjoy the challenge so I can't complain.

Not sure about vibrations as mine has never vibrated or moved so you are not alone there But if vibration was an issue some strips of sorbothane should be enough to dampen out any movement. I feel bad for the guy .... I would be gutted if my printer committed suicide off the counter top.

I've been thinking of similar space saving ideas and improved feeding of my printer following some recent woes with printing ninjaflex. The easy solution would be to put stuff on the floor however with a 6yr old son and 3 mental dogs I dare not put filament anywhere near poking/chewing height ..... so I sat down and over a couple of evenings knocked this simple design up keeping in tune with the UM2 styling. It might work with loose filament if you made a simple turntable in the middle, not sure if it would twist the filament thought. Ideally Id like to build more of an enclosure for the printer as Id like to do some ABS prints but I'm worried about the toxic fumes unfortunately I don't have a spare room with a window i can sit it in. I'm thinking using 30mm T-Slot might be a solution for an enclosure i suppose i will fiddle with cad a bit more and see what the brain matter can come up with

James, Thanks for the link, I will give some of their stuff a whirl

I'm hoping to buy some ninja flex for my UM2, I was wondering how you guys were getting on with it as a material 2 months down the line? I'm guessing the 3mm option is the one i need to go for? I just want to make sure I get it right before I sink £50 into a reel of material.

Is there a new firmware patch to fix the filament diarrhea pre print (if so could someone be kind enough to link it) or do I have to sift through the code and fix it myself ..... its been a long time since I've messed with code, and I don't want to break anything.

I must admit I had to laugh when I realized the smell of weed was coming from the printer. As a by product smell it could be a lot worse. I'm yet to discover what the colorfabb pla/pha and Xt filaments smell like. I will have to play with those later on.

Looking forward to the patch as my UM2 is being a right princess with the new firmware, sods law after I had almost dialed it in on the older version lol. I was poking about the net this morning and i found this that made me laugh: I thought it was fitting

Yeah it was odd behavior, it happened a couple of times then went away by its self with no intervention by myself. I've only ever printed via SD card. I think a strong draft from a door caused the print to fail, if that could be a cause? Also I really don't like the quality of the "gold" PLA that was supplied with the machine ...... thank god I ordered some orange PLA as it prints sooooo much better. Again, thanks for your kind words of wisdom. Over time there will be less "I'm having problems" threads and more "look what I've made" ones

Thanks for the tips I will give these a go later Yeah I am noticing even a difference in colour effects the print settings. But even with all these initial hurdles I very happy with my Ultimaker2 and I understand there is a lot of learning to be done to become more of a natural user. I plan to order some different materials from colorfabb and faberdashery soon so I'm sure that will through a spanner in the works xD

ahhh ok glad I posted this for piece of mind. It hasn't caused any problems with the print that i'm aware of. I just wanted to make sure it wasnt going to burn out the motor or anything. Thanks again guys

I have been having issues on and off with the feeder on my UM2, its odd as it seems to be attempting to push in more material than it can extrude. I made a quick vid and uploaded it to youtube: It changes volume at different stages of the print, the video above is at its loudest. Its not jamming but it is slipping ........ I think. Or is it something else?

Yeah I wont show you guys the abortion of trying to print it on its back lol I'm getting better quality with lower print speeds and printing at 210C.

Cheers for the feedback Conz, I will try that now, I thought it might not print well off a curved surface ....... but nothing ventured nothing gained (I'm finding that a lot with being so new to the world of 3D printing). As ever guys thanks for the information, Its a steep learning curve but i am soaking up as much knowledge as I can from the people who are willing to share

Hi gr5, Thanks for getting back to me Temp was at 215, I have the bed set at 60 anyway as that seems to be the best for me. I will try setting the speed to 30mm/sec but in the second pic it was set at 40mm/sec. Orientation wise the other side is a constant radius so I'm guessing that would be a bad idea to print from? I will check the fan speeds during my next test print. Would having the layer height set at 0.1mm or shell thickness at 0.4mm be causing any issues? I'm using ultimaker filament currently I know from what I've been reading over this forum is not regarded as the best, I'm going to try and get an order in with faberdashery and try their filament ........ but that then lead to the material with no spool dilemma lol If it was easy it would be boring .......

I'm back, and I'm stuck with another technical hicup with my prints ....... could someone please give me some pointers and advice on how to stop the below mess happening on my prints. I thought it might have been the speed of the printer so i lowered it a bit and tried again but I got the same result so i aborted the print to save wasting material. I don't know if this is an indicator to what the problem might be but this is a common sight to the start of all my prints: I really appreciate any wisdom you guys can offer this humble noob while i learn the ropes of 3d printing

Since having the issue I have managed to print 3 25mm cubes with no massive issues, so perhaps it was just one of those things? I have noticed on a couple of the prints the head leaves the print area and returns to home then appears to reset the level of the printer then finishes the print. Is this normal or is it pointing to a potential problem? If you look at the pictures of the print some of the print about a inch from the base is glossy then the rest is more mat in appearance and it gets a bit "stringy" is there any reason for that? Sorry for all the questions but as I'm new to all this everything is a new experience and I'm keen to learn as much as possible to help me produce good quality prints.

ahhhh thats frustrating. I've uploaded one to the forum: I hope this one works lol

hmmm thats odd. I admin another forum that uses this forum software so I'm pretty confident i linked it correctly. It might just be photobucket having a senior moment. Here is the url for the image : http://i650.photobucket.com/albums/uu227/MrLEM/expertsettings_zpsd8180ace.jpg Edit: Did the pictures in the opening post show up properly?

Well it had chewed the life out of the filament. I even had a fight with it removing it. Here is a screenshot of the expert settings, I hadn't found those previously ...... (hangs head in shame) Thanks for your advice its much appreciated ........... Its a dark art configuring the printer but I must admit I am enjoying it (even the frustrating moments)

I attempted my first big print today but it ended in what I can presume was a nozzle blockage as PLA has stopped being extruded. As I came back to check on it and it was printing above the surface of the print with no material being ejected. To say I was gutted would be an understatement. I was really looking forward to seeing the end result too. I'm not entirely sure why this happened but I'm hoping if I post up some pics and the settings I have used someone might be able to shed some light on what might have gone wrong. I have also noticed some quality issues with the print so some pointers on how to tidy that up would be much appreciated Settings Filament = Gold 2.85mm filament from ultimaker (gold was supplied with the kit) Settings Used Print thickness = 0.2mm Shell Thickness = 0.8mm Bottom/Top Thickness 0.6mm Fill Density = 25% Enable Retraction Retraction settings Length - 5.5mm Speed 30mm/sec Nozzle size = 0.4mm Initial layer thickness = 0.3 Travel speed = 50 mm/s Bottom layer speed = 20mm/s Minimal layer time = 5 seconds Enable cooling fan = yes I hope there is a glaringly obvious solution I'm missing or I have overlooked a setting somewhere.

I'm near Ascot in Berkshire

Good pointer there ......... I don't want to jinx it but our power supply is pretty decent. Fingers crossed it doesn't have a glitch now I've said it lol edit: I have noticed a few glitches of the finish on the large print I have running currently, I will get some pics up in the right place once its finished to see if you guys can help me figure out why they have popped up.

Cheers guys this is all very reassuring Now to get on to the fun bit ......... the first big print :unsure: wish me luck
