Nozzles have a much longer lifespan than a month, they can last years I think when you just use them for abs/pla.
only when using abrasive materials (metal fill, glow-in-the-dark) they don't last that long.
Printing that base plate standing up will never produce a good result, crazy overhangs, no base volume.
But I don't see the issue, fit's fine on an UM2, even with brim ....

For a couple of days, ABS worked quite well with the modified settings. I just have to remember to check settings after switching the UM2+ off; "Fan: off" is saved permanently, Nozzle and print bed temperature is not saved permanently to the profile.
These InMoov parts were printed in a couple of days. Quality is good. No misprints in almost a week.
But no luck with thing:172505 from Thingyverse. This is a base plate that doesn't fit flat on the UM2+ print bed (with brim and taping the edges):
I just could not get it printed upside. During the 21 hours print time, something always cracked. E.g. the edges:
Or parts of the support structures:
Once I tried just to continue printing. After about 18 hours, the whole piece cracked from the lower support structures:
Printing this thing is either for experts only, or requires a bigger print bed.
The workaround is to make two pieces of it and print them laying on the print bed. This works like a charm with 8 hours print time for each part.
Other parts of this thing printed fine as well, e.g. these mechanical eye lids.
Then the nozzle suddenly clogged for no obvious reason, which is just scary. I did not even turn the printer off of changed the filament, the nozzle just stopped spitting out material during a print. Applying the "atomic method" seven times has no (zero!) effect. Trying to melt or burn the ABS did not work well (and I am unsure how much heat I can apply before the nozzle deforms). Then I tried to dissolve the ABS in acetone. This partly works (I can remove most of the dissolved ABS from the inside of the nozzle with a wooden tooth pick), but the nozzle still does not print. One step ahead and two steps back. Everything is delayed again until I can figure this out.
I guess the nozzles have a limited lifespan, in my case about one month. Is this to be expected? Another crucial information missing in the documentation?
The replacement parts I found on the net range between ~€15-18 plus ~€6 shipping for an "original" nozzle and ~€2.50 for a set of five no-name noozzles, which is quite a huge span. If I need €15-18 just for spare parts each month, that would be rather bad.
Are there any recommendations for replacements and where to get them in Europe? At https://ultimaker.com/en/products/spare-parts, they only list a 0.4 mm nozzle that is "only compatible with the Ultimaker Original." Where do I get spare parts for the UM2+ that work well?
Thanks!
