2 Central screws-holes printing problems
Hi all,
i have this problem when i start to print upgrade mk2s piece at center of the bed with abs 😐 Someone can help me?
Re: 2 Central screws-holes printing problems
guess that's related to a tiny temperature difference (the screw-holes / bolts always try to cool the heatbed down).
did you print the abs-part inside an enclosure ?
anyway: i wouldn't worry about this tiny "imperfection". especially at this part it simply doesn't care.
if you need to print absolutely plane surfaces with abs, try to allocate the part elswhere at the printbed with your slicer.
dem inscheniör is' nix zu schwör...

What temperature are you heating the bed to when using ABS? I heat my bed to 110 with ABS and have not have that problem. If you're using a lower temp, you can try increasing the temp to see if that helps.

Hi Man 😀 Tnx for reply!
My extrusion temp it's around 255,260 Zotrax Abs , Bed temperature is 100° at start decrease to 90° after . If I leave 100° on bed the wall in the bottom of model they come like this...
I print in a LHACK like model 😀
