I need some help with this part.

Unable to Level Print Bed

I can’t lower the front-left part of the bed enough to fit the shims under the nylon nozzle. If I try, the screw of the kinematic coupling board will fall out. Is there a way to fix this?

Mark Two

I need assistance to better orient fiber into this part.
