Did anyone try the advertised 40 micron 20 microm = 0.02mm layer height of the @Ultimaker 2?
How did it perform? Especially for bridging small gaps?
Does it work reliably or are there many failed prints? Especially on taller parts that make use of the 200mm height.
Not that I’ve had experience with the machine so far, but in my experiences the finer layer height you go the worse bridging you get. Because the calculated flow rate doesn’t put out nearly enough material for bridging to work properly.
I’m sure @Mark_Moissette_ckaos had been too busy to experiment with these heights, but I bet he’ll get too it sooner rather than later once his printers cool off.
I could give it a try if you have a rather small/ easy to print model.
But frankly I just wish the UM2 would work reliably at 0.2 mm layers like the UM1 (which is not always the case)
What kinds of failures do you get?
Missed steps / back slipping at higher speeds mostly: The fact is, it is not a geared drive, so less torque than on the UM1 .
At 0.1 mm and below there are not much issues ,if anything, the quality of the prints out of the box is higher and more reliable than on the UM1.
I managed to solve most of the issues by changing the spring inside the filament drive to a less strong one and increasing the print temperature.
I can post side by side pictures of the same objects printed on both if you want (I have some at 0.1 mm and some at 0.2 mm if you want)
No need to. I’m just interested in >0.5 since I can already print 0.2 and 0.1 with my current printer.
well , in that case, if you have a small test model , I would gladly print it in a layer you want to try (0.02 mm ?)
That would be great.
I’ll send one later. (Will be on a long train ride after work.)
