It's hard to know which adhesion, layer misalignment, Z wobble, separation thumps, screw reversal clicks etc come from what source. The whole mechanical mechanism is a bit 'cut-price' and lets the otherwise nicely made machine down IMHO. I am thinking of an upgrade to replace the whole Z slide with twin square rails. No irreversible mods required, can use existing blue parts. The leadscrew has a lot of backlash too, I am thinking about a simple spring-loaded brass/bronze anti-backlash nut so that each layer is more likely to be precisely the right thickness. I looked at ballscrews but it seems in tiny sizes and pitches like this there is still some backlash, but I suppose very expensive fully ground ones might have some preload. I'll let you know how I get on, I have ordered the bits...(Nut, Slides, Al Plate etc). ANY COMMENTS on the Z Leveller idea? The screws would be tight in the base, spin the thumb-nuts up to touch the underside of the top plate and tighten nuts above....that's the plan.
