Upgraded my UM2 to a 2+. First print.

I just finished the upgrade of my UM2 to a 2+. First of all, hats off to Ultimaker for making their machines upgradeable rather than forcing us to buy a new machine to keep pace with the latest tech. The upgrade was pretty easy, UM video was a big help.

First impressions: this thing is quiet! The new fans are terrific. About all I hear now is the whine of the extrusion motor when the filament retracts. I keep the printer in my office and it is much more comfortable working while it is printing because it is so quiet.

I was reluctant to print anything after the upgrade because I was afraid the print quality would not be as good until I tweaked things. My UM2 was really dialed in. But I printed this weevil by 3DKitbash immediately after the hardware and software upgrade. I used the stock PLA settings and printed at 0.1 mm with the 0.4 mm nozzle (50 mm/s) with Ultimaker Blue PLA. The nose was printed on its side as a separate piece. Pics are as-printed, no clean up.

The new nozzle seems to use heat more efficiently. I was able to print at 10 degrees less than usual with this filament and based on the look of the print I could probably dial it back a few more degrees. Maybe my old dirty nozzle just needed more heat to melt the plastic... The new glass clips are much easier to open and the new extruder makes changing filament a breeze. With the new extruder I never heard the familiar click from when the pressure gets too high like I did with the old one. Anyway, I am very happy. Great upgrade, highly recommended.

I'm so glad you like the upgrade. Your print looks fantastic!

Thank you for sharing your feedback! How long did the entire assembly take you?

Another reason for your temperature difference could be that you have a new PT100 in the extrusion upgrade. One with a different shielding which makes it more accurate to read the temperature. Of course your old nozzle could act slightly different, but perhaps your previous PT100 indicated a temperature of 220ºC, while in fact it was 210ºC. And this PT100 gives you the right temperature of 210ºC.

I didn't time it. Maybe 2 hours without rushing?

PS-I'm still shocked every time I turn the power on just how quiet the new head is.
