Yep pretty much... but is it possible to simply splice two stls together on cura?

So has anyone had much luck with this? For example if I want to piece together two objects and have each one as a different colour, it seems rather difficult to do in cura. Does anyone have any suggestions for doing this? without having to go through a cad program? Thanks Jem

Hey guys, parts arrived today or so I've been told... groovy :-) hey sander, I'm away on business...

Hey, my stuff got shipped! however i won't be in the country for a number of months so kind of a waste of time really.... anyway's ultimaker, the ultimaker 2 is brilliant... now all you need to do is sort out your delivery service and everyone would be happy. Thanks all the same!!!

Hi, We got a um 2, beautiful machine, works great :-) however customer support / delivery is still atrocious I see hence the reason why I'm posting here. As ultimaker don't seem to answer emails etc Ordered around 300 euros of parts etc over two weeks ago... no delivery, no response... Do I as a customer need to travel to the netherlands to pick up my parts? We needed the parts a week ago... too late now.

Ok The jam's been fixed the above method really works well... it looks like the cause was that the reel was getting caught somehow... so I've freed it up to prevent that from happening again... the more you know...

Btw new power connector at the back... really bad idea... It falls out and gets damaged way too easily.

Hi Unfortunately its jammed again... I've trying doing the above method but the filament won't even come out of the bowden tube. It's completely jammed... any ideas how to remove it without damaging the machine?? I also assume that there is a jam in the extruder itself which caused the problem in the first place. the only thing I can think that caused it, is printing low quality fast speed....

Thanks guys! :-) that got it working..... does happy dance. :-P

Hi Don, There is no filament coming out. It's grinding away at the back. Raising the temperature to clear the nozzle makes no difference. Inserting a needle makes no difference. The machine has gone back to the factory settings and keeps going through the setup but no filament comes out.

Hi, After buying a number of um 1's, cubex's etc we have been given a um2... afetr unboxing, following the procedure, etc I'm guessing it was too close to the plate or something, it's jammed again (just like the good old um1) and I'm not able to clear the nozzle. Can anyone offer any advice? I don't want to spend 90% of my time fixing ultimakers! Thanks Jem :-P

Finally got a reply and an apology. Parts have still not been sent out. Where I work, we have about 50 Um's 1's and 2's, most of those aren't working / waiting for parts. I've scrapped the um1 at this stage and moved to a different supplier because the hardware / customer service is crap. Best of luck everyone with your machines! :-P

Day 20... still waiting for a reply...

Ok thanks guys, Just emailed.

So I'm pretty fed up with um, I ordered over 300 euros worth of parts about two thirds of the order was delivered. I have emailed them, I have called and I get no response. It's a good job this stuff isn't urgent isn't it? Their bad delivery service is really letting them down.

Well as long as you don't need to heat any of them up!

Hey anon! So it sounds like the three heater dealies on the main board could be repurposed as say a way to control three pumps or to switch on and off devices? Like could they be used to simply switch on say a print head? And then switch it off? I mean that is essentially pwm. So I guess this means you could have at least 5 extruding devices from the main board in theory...

ah well, if you are using medical pumps say... temperature is not an issue. With the firmware I would imagine its just a case of simply duplicating some function a number of times? It doesn't sound too difficult to do... :-P

Hello anon! Well I was looking at pump systems and I figured that all you needed was one control line to switch on and off those pumps. So you could in fact have quite a number of extruders or pumps or whatever running from the board... Like if you had two pwm devices you could switch two doc pumps on and off, causing liquid to flow in a semi controlled manner then use the two extruder ports to directly control screw driven extruders... Antsy way there are possibilities here me thinks...

Sooooo I was wondering, the main board can like drive two extruders Ons um 1 but could it in fact control more devices? That is could each line be used as a switch? Like as in pwm? Has anyone tried this? Thanx jem

No we're like hardcore physicist's here, we don't wear safety goggles or lab coats because we are cool. Only the biologist do that. Mind you, one of the syringes exploded and there is blue gelatin on the ceiling. We were lucky... that time.

Hmm, yep I have a heated bed and I have it working too just using a regular bench power supply and a multimeter to monitor the temperature. I have'nt integrated into the machine as who knows what will happen? haha Well i found the kapton tape has been brilliant, you can get large reels of it from robosavvy I think? Its like 25 euro or something and that will last for ages and ages. I'm reluctant to add too much hardware mods or tinker with the firmware as the system is not so robust I feel....

Hi Sander, UM1, for the moment, we have loads of those on campus here.

That's a great idea!! I wonder if its like the kapton tape? Have you tried that? Well you apply it across the platform and use a credit crad to remove the bubbles as you apply it. Pla prints very very well on it and best of all after a minute, it cools and you can pop it off easily. Also the underside of the printed object is super shiny and smooth. And the tape lasts so much looooooooooooooooooooooooonger than the blue masking tape which is ok but not great.... I'll have to try that, thanks!

So to kick this off, we were given some printed feet which made quite a difference to the operation of the printer in terms of vibrations and noise really. Has anyone made or added anything that really worked for them? :-P
