Hello, My UM2+ used to print everything that I threw at it perfect with both pla(colorfabb and ultimaker brands) and petg(madesolid, colorfabb xt and makergeeks brands). I ended up taking on a job from 3d hubs where I printed a few hundred hours worth of petg at temps 250/70. That job printed great but now that I am trying to do my own prints everything just seems bad. I have done several atomic pulls and even took the nozzle off and its clean inside. I am now trying to print with colorfabb pla that I have used before with no issues. Here is a picture of the first layer. It is very uneven where some spots are full/normal looking and others are very thin. I am also getting a lot of lifting now, where before I never used to get lifting. Here is a 4 piece part that I printed that should be straight when put together but since the lifting is so bad it is way out of wack Also, the bottom of the prints have these weird wavy lines: Any ideas?

Your, and my, investments are safe. The UM2+ in an amazing machine. The UM2+ and the UM3 are in completely different categories of machines and price. I don't think Ultimaker is replacing the UM2+ with the UM3 but just adding an additional printer to their lineup.

When the UM2+ first came out and all the shops dropped the price on the UM2 it was cheaper to get a UM2 and upgrade kit. I, and many others, still went with the UM2+

That's awesome! I didn't know about that. I didn't get to watch the videos yet, just saw the tweets. This is going to be an exciting printer to watch what the community does with when they get their hands on it. and +1 on the UM2+ being the best single head. Still 100% happy with my purchase of it.

I understand that disappointment but I think that would be a huge upgrade. I have a different mindset though as I've had my 2+ since February and not just for a month. The 3 is an additional $1000 over the 2+ so that is a pretty big difference for the additional features. It's not really in the same pricing category.

The swappable print cores look very cool. Of course the dual extrusion is awesome! Active leveling is nice. Integrated camera, but will it work with octoprint? wifi! woohoo! NFC read with chips on the spools... thats cool i guess. Overall I like the new upgrades but then I saw the price and for now I am happy with my 2+. If I was in the market for a new printer though I would probably get the 3.

What filament are you using?

+1 on what everyone above is saying. 60C for Ultimaker/Colorfabb PLA. No glue needed. and wait WAIT WAIT for the bed to cool down and the part will either already be detached or come over very easily with no tool required.

I've never had to use glue with Colorfabb PLA. Did you level the bed?

Just noticed this little pool of oil around one of the vertical rods. Is this bad/normal?

Still enjoying the esun petg? I am thinking of trying some out with your settings.

Thanks but they have the 1.75. I have the stock 2.85 Are you sure? It says its for Ultimaker which means it would be for 2.85 as there is no stock ultimaker with 1.75. I would contact @gr5 and confirm. Good luck!

I think you should buy whatever you are more comfortable with. From reading this thread that seems to be the zortrax, however, you also seem to be comparing the zortrax to the um2 print quality rather than the um2+. I never had a um2 but from reading a lot here there seems to be a difference in print quality out of the box between the two.

+1 on what Titus said. I'm not interested in an extrusion upgrade kit but I would love some filament rolls! (if I was to win of course).

I am testing out your settings with some madesolid pet+ that I got from amazon a couple months ago for cheap. Under 15 bucks a roll. I wish I had gotten a lot more now that I see the regular prices. Anyways, how is the esun working out for you? You using the same settings as above?
