Great post Nico. Glad your much happier with your printer this time !!
1) Packaging of the plate. Completely agree. When I set my printer up I had no idea how to remove the plate and YES I heard that loud noise when I switched the printer on and thought I had broken something.
2) Test print. Agree on this too. I have a blue test print, yet the nozzle had remains of brown or silvery colour inside it.
I must get Robert`s chain too, it seems I`m the only one who doesn't have it yet lol

Hey guys,
Ultimaker replaced my old UM2 (thanks!) and the new one just arrived. The first thing I did (after tightening the pulleys) was to print the extrusion test. (230°, 60° bed, with half empty spool on stock spool holder).
Well I wish I had one of those machines illuminarti tested that refuse to fail, but no luck here. Maybe I'll just have to disassemble the head and put it back together (will definitely do - the 3rd fan drives me crazy - see below):
It starts to underextrude at 8-9mm^3/s. I loosened the head screws a wee bit but this made the extrusion test worse (object on the far right).
Then I installed Robert's fantastic low friction spool holder (link). Now it is a bit better. It starts to underextrude at 10mm^3/s with some visible artifacts from underextrusion at 9mm^3/s.
Well it is actually a world's difference to the first printer. I can't complain. But if I wanted to complain, here are some small things I noticed (also feedback for Ultimaker - Sander if you are reading this, please realay it to whom it may concern):
1. Packaging
The glass plate was stuck beneath the z-stage. This is a clever idea because this way it can't move and wouldn't break. But it is not possible to get it out without powering on the printer. And guess what happens when the first run wizzard tries to move the z-stage down :/
Well, it is possible to get the glass plate out - just by turning the threaded screw. But this isn't mentioned anywhere. Besides a new user wouldn't know that the first run wizzard will try to move the z-stage down. It makes a hell of a noise and you'd think your printer just destroyed itself...
2. Testprint
Guys, if you really perform those test prints on the machines you ship, it might be a good idea to inspect them before shipping. Here's a side by side comparison of the test print from the first UM2 and the second one. Underextrusion is hard to miss on the first one...
And by the way - how many test prints do you run on one machine? My test print was done with blue filament but the nozzle was full of green filament so clearly the last thing printed on my machine wasn't the test print.
3. Heated bed reverse logo
I noticed that the heated bed has the Ultimaker logo engraved on the bottom. It is reflected on the aluminium plate but it is backwards. If you want to make it look cool, just flip the logo so it reflects correctly:
4. Stickers
Finally, stickers in every box! Thanks! I dig the UM robot but the "photo stickers" look cheesy. Might want to go with an abstract illustration of the printer instead of a photo.
5. 3rd fan
I hope it is not normal but my 3rd fan is loud as hell. It is either broken or pushed too hard against the aluminium wall.
Check this out (volume up!)
And now a few observations. Judging from the number on the box my first UM2 was shipped in, I had unit 349. The second printer seems to be unit 1434. And it shows. Here are some visible changes:
New fans (brand name: Deep Cool :cool: ), spacers for the head screws, blue clips instead of red ones, and cushioning or something simmilar for the extruder motor. Not visible here but one can see it when peeking from the top. And now the printer is mostly free of black gunk that used to hang on the blackened parts of the case. Oh and the threaded rod doesn't wooble like before. And I don't know if the glass plates are coated with something special, but everything sticks like crazy (which is good). I even broke off a extrusion test cylinder when I took it off.
Now if you'll excuse me, I need to print Robert's cable chain (link), I feel so naked without it :mrgreen:
