Hi

I am now 95% of the way of a functioning 0.92.8 firmware for the Rostock Max V2.

Everything seems to be working, except that my prints are now coming out too big.

A 40mm test cube prints at x/40.86mm y/40.86mm z/40mm.

I am unsure which setting I need to change to correct for this.

Any ideas?

Have you calibrated your extruder yet?

As it's a consistent scaling factor on x and y, but not Z, I believe the fix is to adjust your diagonal rod length setting.

(Observed size / Specified size) * Current arm length setting = New arm length should get you a working arm length.

Diagonal rod MUST be as specified. 290.8 for the ball cup arms, 269 for the u-joint style. Also, do not change the steps/mm from the default of 80.
