Proxes

My UM2 came without it, so i printed it. That was my first print and it came out perfect. ah okay, nice one then!

I don't think the spool is the problem at my printer, but thanks for the tip!

I use the normal guide, delivered by the UM2. Do you have a printed one?

Thanks, ill consider the .6mm nozzle. Also thanks for the recommended speeds, awesome help!

hi guys, I did a extrusion test, and i am very satisfied. It went up to 6mm^3/s without any problems, then between 7 and 9 there were some thin lines, but no interuptions. It failed at 10mm^3/s. I found out that i had to print with a higher temp. I changed the temp from 210 to 225. No problems anymore! Thanks for your help guys!

Thanks! Gonna try it tomorrow

Okay, that doesn't matter. If you have em anywhere this week or so that will be great! I'm currently running a print of 23 hours so i can't print it anyway haha

I had the same problem. i solved it by changing the gap between the real print and the support. This gap is usually 0.15mm, i changed it to 0.05. the support still comes of pretty easy, but the lines that are on the bottem of the print look way better then before.

okay, thanks. The bed layar is correct then. I have no problems there. The layer height is 0,2. It does indeed happen at prints wit heavy retraction, but also at prints with more then a certain amount of mm^3/s. I believe it is 3, but i cant test it because the link to the Gcodes doesn't work anymore. At least not at my pc:P

Anyone else has problems opening the 'here' link? I got redirected to the dashboard site of ultimaker forum.

That could be the problem yes, but that should be only on the bottom layers, am i right? The problem i have is that when it needs to push more then like 3mm^3/s uit, it will just pop and start to under extrude. (just as my latest print :( ) The under extrusion happens after like 2/3 hours printing and is solved after 5/6 hour (just guesses). Can that also be related to the bed leveling?

I tried to download the test, but when i click the highlighted 'here' it does open the ultimaker dashboard site in stead of the Gcodes of the test. I dont get a download either. I use PLA at a temperature of 210 degrees.

Okay, but is it normal that it does 'tac' with standard cura settings? (50mm/s ; 2.0mm^/s) I have cleaned the nozzle as they advice here: it all came out clear. I personnaly don't expect the nozzle to be clogged because I am only printing for like a week or so. I do have underextrusion, and as i sad before, under standard cura settings.. If i put the speed down to like 45mm/s and some adjustments to the infill speed etc. I am able to print without underextrustion, but in my believe the printer should be capable to print way faster. (at least thats what i read on some forums) Is there a standard what your UM2 should be capable of? like 8mm^3/s or anything like it? And if there is, is there a particular way to test it? thanks for the guides, I'm gonna take a look at em!

Hi there guys and girls , I recently bought a ultimaker 2 extended. I love the machine only i got a little problem. The extruder 'pops' on the rear, even when i print with the standard settings of cura. It looks like the engine that pushes the filament in isn't strong enough or something. Its slips back like a quarter of a round when it pops. does anyone of you know why the extruder pops and how to prevent it? besides, any tips and tricks with the UM2 are welcome Already thanks guys !
