Hello all,

When I print with Z-ULTRAT material, I've got sometimes spot on the printed part. But I havent this problem with Z-ABS

I use last Z-Suite firmware

Select Z-ultrat material

0.19mm layer

V1 extruder (and cleaned before printing)

But the Z-ULTRAT spool I received from a french webstore doesn't look like other spool?
