Aaron, What an informative and interesting post. Very nice job indeed ( even if I am not sure my modest brain can compute everything lol ). Although this is hypothesis, it all seems to make good sense and should be investigated further. I wish I was brave enough and skilled to help! Keep up the good work. I will follow this thread with a keen eye! And Cohen, great to see you jump on this so early

Thirty, your just around the corner from me. Was in Lichfield on Monday night eating in the thai restaurant I`m in Tamworth. 3dhubs, I`ll look today and join up. I need to join up on thingiverse too!

:mrgreen: Print makerbot logos until the end of its days :mrgreen: I always knew rice was a good desiccant, just didn't know I should store my filament like that. Every day is a school day !

Haha Nico, burn in hell maybe a bit harsh, I just hope your new one amazing I found this article earlier and thought it was worth posting, even if most people probably already know all this stuff. I learnt a bit from it, I need to get more rice lol http://bootsindustries.com/portfolio-item/importance-of-good-filament/

Hi Keith, What a great subject and interesting print that must be. I have seen his website before. I tried using some loctite glue a couple of days ago ( cant remember the number sry ) but the glue "burnt" the surface of the PLA and left horrible white marks. I guess I could of been more careful. Does the glue you use do the same? Great bit of info. Thanks! Do post images of your clock when its done

Oh I see, so the smaller O/D of the complete roll of filament causes a tighter bend radii upon entry to the feeder. Makes sense. Thanks for clarifying. I will keep an eye on that too.

Fair play ! I do wish to add.. I am NOT going to muck about with mine.... yet

Hey gr5, I have done some basic measurements on filament ( very basic as I only have two types ) and I did not find much fluctuation in filament diameter, either at the ends or in the centre of the real. I am seeing a fairly consistent 2.85 - 2.95 diameter. This is with Ultimaker blue as supplied with the printer. I did notice quite a few small notches ( tiny ) along a length of the filament though, but doubt this effects anything. Filament falling of the reel and twisting IS a bugger though and once the filament bends and twists its a nightmare to set it straight I am not expecting anything from ultimaker, just merely pointing out that a little more involvement, mainly within the modification and hack section, wouldn`t be a bad thing. Touch wood so far, like you, my um2 doesnt seem to be having any faults, especially to the level of poor old nicos, but I may not have pushed the machine much compared to others. I hope he gets it resolved!

I noticed just last night that "fix horrible " setting was ticked... so switching that off is best right ? Who named that feature fix horrible... love it lol What lovely nuts you have Don :mrgreen:

Hey Daid I will have a look for those models, I`d be interested in seeing them anyway. Can one assume that one`s warranty would be void if one was found to be "tinkering" with ones machine ? lol

Hey Daid Thanks for the response, don't worry we all know and understand the pressure and hectic lives of the ultimaker team at the moment. Success is a good thing to worry about and your all doing a great job! This is an open source forum so I will always welcome any suggestions put forward by the community. If we take the feeder development as an example, if would be nice to know, quite early on, if the " Ultimaker team " actually agree that the feeder mechanism could of been a contributing factor to some users problems. Have the ultimaker team already considered a redesign...have you received compaints or feedback regarding this component...etc. If the community knew the answers to these questions, they may be more inclined to spend time/money on helping and making suggestions within this thread development. You say that the injection moulding stage introduced new issues as did the springs that were installed on early machines. This information could have been placed into the feeder development topic so that users could interpret this info and do with it what they may. From my point of view, I was merely suggesting that as a new user, I do not have the knowledge about the feeder system to give any constructive advice as to whether or not it is actually a cause to any problems experienced with the U2. If however I knew ultimaker would keep a close eye on these development and be interested in the outcome, then I would be more inclined to offer design input/suggestions knowing that its not a waste of time. Apologies, I`m ranting on a bit haha. Over & Out for now.

No prob. Started a new thread. By the way. As a new user, I have already experienced the " thin strands of PLA to pull from the feeder during material change ". I think that aspect of your design proposal is a winner

I originally posted in Ian`s thread about his work and dedication to improve the feeder system. I think he has done a great job and commend his effort to improve the U2. I have also read about numerous other designs / improvements submitted by others and fair play to them having a go too! I am sure I may come up with an idea one day to try to benefit the community. However... as a novice 3D printer user I really have no idea if some of the modifications / hacks that I see bounced around the www are a real benefit or not. So, considering we pay £2000 for a piece of kit I would like to see some input from the ultimaker team / designers on these modification threads. Open Source is fantastic, and it is this which drives improvement...but again as a new user, I would like to see some comments/input from " ultimaker professionals " before I start to dismantle my £2000 toy and rebuild it with parts found on the web ? Also, it would be nice for community designers such as Ian to receive some feedback, good or bad, from those who " are in the business ". Thoughts ?

What post ( I just deleted it... wondering where to out it lol )

"having fun and making money ". I need to do the second bit

Wow markus, good find I want my ultimaker to smell of oranges instead of burning PLA lol

Nice work Ian, very persistent If you use the small feeder clip on the left of the box that should help right ? Probably don't need to design a new one. I would prefer to see a larger chamfer / entrance on the top section of your "D" shape, it looks quite tight for the filament to enter? Keep up the good work fella !

Yeah exactly the same item placed twice onto the bed in Cura. In Cura the support features looked exactly the same, but printed out they were different.

Hi All I have noticed on more than one occasion now, when I am printing duplicate`s of the same item ( in this latest instance just 2 pieces ), the Brim created by Cura has slight differences. Now this has not caused me any issues, apart from slight confusion as to why it does this. The only difference on the two items being printed was their orientation on the build base. Does this happen to anyone else... or just me :???:

Awesome. Good to know. Just been reading about the 2nd extruder and the possibility of water soluble support material :wub:.... me wants NOW !

A bit of a wait... but there one later this year. www.tctshow.com

Thanks Ian, I just hope the heat from the radiator below doesn't effect the brackets and the board falls off lol Has anybody had experience of PLA or ABS deforming after a certain amount of time? I know some of the SLS/SLA prints I have received from commercial printers don't last too long once moisture has its way.

Evening All, Top gear and Dragons Den have finished and I got no red wine left...so i`m back at the ultimaker stuff lol. Last one from me tonight, I seem to have done quite a few prints today What is this strange looking gadget I hear you ask : SnowBoarders or Skateboarders anyone ? Over & Out !

I quite like the idea of getting into sculpting, clay sculptping none of this digital stuff So I had these sculpting tools rattling about on my desk for a while... I decided to make this little stand for them as a speed test. Printed at 70mm/s at 220. These little bits shot of the printer... i though the printer head would shoot off at some point too lol. Hmm maybe i should of put some c/s holes in the base and screwed it to the wall. Looks like a medieval weapon

Same as Cor3ys, got mine at Imakr. No issues to require support from ultimaker so far ( touch wood ).
