Re: Printing Problems

I wouldn't call myself an "expert" but with three weeks of Up and a couple kilos of plastic under my belt, here's my thoughts.... The most likely cause is probably jammed or bad filament. If the filament gets stuck, the drive gear can dig a hole in the filament and leave nothing for it to grip. The ...

Re: Mac software bug? Can't reset platform height

Hi Plepik, Just copied and pasted this form the manual, and this may be your problem: Thanks for the pointer, but I don't think this is the problem. I'm only trying to adjust the height by 1mm or so, and also the Mac version I'm using (1.2) does not have a box in the "Setup" window for the nozzle h...

Mac software bug? Can't reset platform height

Has anyone else had the problem that the Mac software won't accept a new value for the platform height? Here's what happened--I set the platform height when I first got the Up, using the perfboard as a base. So far so good. Then I did some experimenting with a piece of glass, which is a little thick...

Re: Color rolls

Just to bump this thread and share my experiences. I've bought filament from: http://www.protoparadigm.com: Prompt shipping, and they seem to take quality control seriously. Read their blog for a much-too-long explanation of why filament diameter is critical. Worked perfectly in my printer. The pric...

Re: PLA tips anyone?

If the withdrawn filament looks all melty and abused by the stepper gears, then the problem is likely an overheating issue and/or filament diameter variations. Some people have had luck attaching additional heatsinks/fans on the extruder to cool it down. I've not tried that yet. There's about a qua...

Re: pp3dp printer

I've used filament from Up, 3dprinterstuff.com and ProtoParadigm.com. There can be a quality control issue with third party plastic. The filament I bought from ProtoParadigm has worked perfectly, but one roll from 3dprinterstuff had a short segment (maybe 2-3 feet) where the filament diameter was sl...

Re: pp3dp printer

I've had mine for about three weeks. I'm on track to hit 15kg in four months at this rate... I'm ordering a 30lb spool from ProtoParadigm. For that size reel I'm paying about 2.6 cents per gram including shipping--but it's a special order item, so will take a month or so to ship. Figuring out how to...

Re: PLA tips anyone?

I got a piece of glass to print on, and the PLA definitely adheres better to that than the painter's tape or the perfboard. The problem I'm having now is the filament randomly stops extruding. Sometimes after just a few seconds, sometimes after several minutes. Each time I can get it to work again b...

PLA tips anyone?

From the archives I see that some people have gotten success printing with PLA. I'm trying a spool of natural PLA, and having a dickens of a time getting the stuff to stick to the platform--it pops right off and I wind up with a mess of spaghetti. Any tips? I'm using the PLA setting, both with and w...

Re: 3D Systems major copycat?

To my eye the similarities mostly reflect the engineering design choice of having the printhead track the X axis and the platform track the Y axis. That's not the way a Makerbot works, but it's a very sensible approach. Once you make that decision, the major design elements fall into place: the over...

Re: Filament supplier motor not advancing reliably

I solved my problem: I opened up the motor assembly and glued a small piece of scrap plastic (about 2mm x 5mm x 0.5mm) to the end of the arm that it supposed to press the microswitch. This extra material is enough to make sure that the switch is activated with almost any movement of that arm, even i...

Re: Decision time: UP or Ultimaker?

I think it comes down to how much time you want to spend printing vs. fiddling with the printer. If you're thinking of buying a 3D printer at this stage in the market, you must be something of a tinkerer to begin with, and many people get a lot of enjoyment and satisfaction from assembling and tweak...

Filament supplier motor not advancing reliably

I've had my new Up for about a week and a half and I'm starting to have the problem that the filament supplier isn't advancing reliably. What's happening is that as the filament advances into the extruder, when the end of the filament tube bumps the housing of the filament supplier it doesn't always...

Entering calibration values on Mac

I just got my brand-new Up printer yesterday and enjoying kicking the tires. I noticed that one of my models is a little cockeyed, so I printed the calibration model per the instructions in the manual, but I can find the menu option in the software to enter these values. One of the verticals is seve...

Any UP owners in the Twin Cities area?

Are there any owners in the Minneapolis-St. Paul area? I would love to take a look at one of these in operation before I decide whether to buy one. Thanks!
