Ever since I got the modular bed on my Mini I have been having bed adhesion issues. I’ve been dealing with them for a while, with some materials it’s worse, but I’ve made it work.
Lately, I have been trying to sort them out and I feel like I have been just driving into a brick wall every time.
I have adjusted the Z offset, but I still have lines. If I move it down any more it will be too much. Currently it’s at -1.54.
I took the bed apart and noticed the metal plate was bowed a bit, so to fixed that to make sure there is constant contact with the glass. I’m going to be hitting the PEI surface next with 1500 grit sand paper and see if that helps at all.
Here are some sample prints with IC3D ABS. Roctopus tune with fine settings (0.15). This is the best I could get, there’s a little lift at the red arrows, but the print stuck and was good. Still a lot of lines on the first layer.
Now same settings, but less detail (0.25) and here is the part I am trying to print. First layer looks horrible. Part 1 is a complete print, and part 2 is shortly after with a higher bed temp. The red arrows point to the corners that lift at print. Lots of scaring on the surface.
This is super frustrating, I never really had these problems with the original 3 part bed, but I refuse to give up thinking that this bed can’t work. I know ABS is hard to deal with, but I’ve had worse luck with PLA.
Any advice would be greatly appreciated! Hoping to get this little bugger dialed in.
