I have a PB+ V2 now and while I like it, it is really slow, like 20mm/s and doesn't like to go below .2mm layers. I'm thinking about swapping with a 0,8 nozzle and turning it into a PET focused machine since slow speeds seem standard with that material.
The main pet peeve I have with the PB+ is that the bed, even with a piece of glass, is far from flat. I really only get a 6x6 area since the bed, crowns a bit and has a twist in it too. With ABS, my preferred material, even with 20mm brims and glue, the corners are no-gos.
I'm trying to rationalize the UM2 my thoughts are:
-Actually much finer resolution
-Faster speeds
-Seems inherently more accurate
Will I actually get the full bed? How much of a brim are people using with ABS?
I could do some upgrades on my PB+, but it would be a couple hundred bucks and a few day (for me) of tearing it down and bringing it back up. The metal bases seem to be cast and I see a lot of reports that they aren't flat (enough).
Had a school project for my 9 year old son where we printed a model of a building. Took almost a week of around the clock printing to print it and in a lot of sections. I think I could have printed it in about 2 days from the speeds I'm seeing on youtube.
Thanks
