as for the warping...do you use anything on the platform? glue? abs slurry? I generally use the latter and I stopped seeing the raft lifting from the platform
although I should mention that I havent done a large print in a while.
The cat I printed a few weeks ago was done with z=ultrat as well and I havent seen this kind of issue with it but spills yeah, lots of, unlike the z abs prints I am doing now which dont present that problem…so perhaps Julia is right and there must be something wrong with the z ultrat profile and the slicer?!
generally I would say that i would not expect that behaviour with ultrat…
another thing would be to heat your enclosed m200.
I built myself a temperature controlled 100 W heating element to keep my inside temperature at exactly 40 degree Celsius. … but we’re getting OT here ☺
There seem to be more issues with the current Ultrat profile.
I'm printing a larger part right now with normal speed, 0.19, and Ivory Ultrat and the seam is brown. Only the seam...an nice brown line over the whole part....everything else is beautiful....no other brown spots.
Could it be that the newly introduced slower perimeter speed (to avoid ghosting) is a bit too slow when doing the seam movement?
Nozzle is almost new and was very clean when starting the print.
