1st layer error - brand new Mk4
Hi all
Ive got new MK4 prusa in enclosure , and i print for ~6 hours
before it was ok , nad now im having problems on the 1st layer, and no idea how to solve it.
the surface is rough and bumpy in some places.
Im using prusament PETG 240/85, default settings, and test models that previously was ok.
ive play with nozzle temp and 230 -240 ive got best results and higher than 250 is getting much worse.
the 2'nd, 3rd, 4th, 5th, layer is affected by the 1'st bumps but them it is almost perfect with no issues
the bed type is smooth, freshly cleaned and added thinnest glue layer as possible.
do you have any hints for me ?
thank you
.
