Chris, that`s rubbish news, sorry to hear that! Hopefully your next one will be perfect and you`ll be up & running in no time.
Thanks Skint!

Yes, that belt is very loose, and likely to cause problems. Is the top section of that belt very tight, compared to the other belts? I fear that something may have broken in the sliding block to leave that much slack, but maybe it's just not very well positioned on the pulleys.
Use one of the little allen keys that came with the printer to loosen the grub screw in the front right pulley that the belt goes around. Then rotate the pulley a little to even up the tension between the two halves of the belt, then retighten the pulley.
The belt has almost an inch or so of play in it and looks perilously close to skipping on the teeth. The top section is about as tight as the other belts are.
Following a nice chat with HAC, I've actually now rejected the printer and as agreed with them, it's being returned to be swapped out with another Ultimaker2.
As, I discovered that when the printer sits on a flat surface it will rock on two legs so something somewhere isn't good! The shipping box has signs of impact damage on one corner (which I didn't spot) so it would appear it may have become damaged in transit.
Shame, these things happen I guess, but I reckon in the meantime I'll just spend more time getting to grips with OpenSCAD, as I have several more projects in mind now!

Hi,
My first print:
Quick question, what is causing the holes or bubbles?
(The print is with PLA on all the default settings of the Ultimaker2)
I've noticed that the underside of the front belt is very loose and there doesn't appear to be any means to tighten it.
Has anyone any ideas on the holes and also the belt ? :???:

This is a very useful thread. I'm very new to 3D printing and have been looking at which CAD packages I can best get on with and "relate to" I'm tending to gravitate towards OpenSCAD at the moment, only as it somehow makes sense to me and I'm finding it fairly straightforward to generate results quickly. My applications are more of an engineering bent than artwork so I completely agree with DonMilne.
I do a fair bit of embedded microprocessor projects so I guess I quite like OpenSCADs "C" type feel. To an extent the design becomes self documenting if you liberally make use of the comment fields which is another feature I quite like about it. Especially good when you come back to a particular design after a few months wondering how to change a particular part of it.
CAD software is interesting - as I think, there doesn't appear to be any defined "standard" to it. Each manufacturer has their very own particular take on how the interface should be for the user, a little like pcb design packages and the choice is really quite large. So I think try them all, at least those which have free demos, and settle with whichever package you feel you can best relate with.

Hi from extremely wet Gloucestershire Euan!

Cruster, Ive only had my printer a week or so, you`ll be amazed at the ease getting prints out that look that nice. I have made a few items now with counter sunk holes everywhere, and so far, I have not had to drill out anything manually to use them. Tomorrow you`ll find out.
Hopefully there will be a few of us UK`ers meet up soon too, if your up for a pint
Up for a pint? I am most definitely! :grin: Just got back from Shrewsbury, no idea what happened to all the snow that was forecast, it was particularly nice & sunny up there.... here of course, it's still raining. Now I just got to find a good space for this lovely machine!

Thanks, I'll try that. I'd wondered if any of the holes might need any supporting, but it seems they won't which is great!
Do you know if there's 'a rule of thumb' for when something might need supporting, or is it a case of just trying it out?
(edit - just spotted your advice about meshmixer - downloading that now)

Hi illuminarti, Skint.
I bought it from these guys who are up in Shrewsbury: http://www.helpanyonecreate.co.uk/
Not too far to travel up (when you're as excited as I am now :grin: ) although I'm now seeing snow is forecast along the route I'll be taking tomorrow...... Oops! :shock:

Many thanks!

Brilliant, thanks GR5. Hopefully this will work

Blimey! Those are impressive, was that second print done in that orientation ? if so, wow!
If I've done this right then hopefully there might be an image attached here.... (edit: I'm getting "You are not allowed to use that image extension on this community") the image is a .jpg (it's a small screen grab)
I'll see if I can locate that recent post about adding images... :smile:

Hi all,
I've just today purchased a Ultimaker2 and I already have a print I'd like to do with it. It's a bracket I've designed in OpenSCAD
What I'm wondering is, what might be the best orientation of it for printing, as there are some holes which run through parts of it.
But first.... can any kind person please advise me how I upload a screenshot of it? :grin:Thanks in advance!

Well, after a very long time looking at all the various 3D printers out there, I finally took the plunge and bought the Ultimaker 2 today :mrgreen:
I'll be picking it up tomorrow and can't wait to get printing. So, Hello all!
Can your UM2 printer achieve 10mm3/s ??? Test it here...

Fabulous!
I can see his mouth moving and I can hear words coming out and solely for that reason I'm now firmly of the conviction that every household should have one of these
