@droftarts i had 900 and tested 1200 and 600 with no change. i will check some more but i had never printed with the corners in this orientation since most of my prints are 100 rounded. Since my motors are original LDO Nema 17 w/1.8deg and a high amp rating i am running them X2050.00 Y2050.00 Z1000.00 and they hardly get hot even after 15hours of print time.
@timcurtis67 i had checked the belt slack also as also proper tension and i think i am ok on this, but i will try once again.
