Bob, can you please describe your MD65 mods? I'm currently in progress of ordering parts to build an ELS for my MD65.
So far I'm only planning a Z drive, got a 4.8 Nm NEMA 34 stepper from stepperonline.
With regards to cogging, I was thinking about keeping the original dog clutch, to disengage the stepper when I want to use it manually.
