Re: [Emc-users] Shizuoka Four Axis on eBay
The mazak at galesburg fest did spindle orient using the vfd and encoder. It was a bit 'loose' because of the gear box play. It worked ok as far as I could tell.

Hey, I've just seen an idea on that machine, if it is what I think it is I been pondering for a long time on what to do about a sloppy quill in order to CNC it, and it looks like it might have been done on this machine. Instead of trying to snug up the quill, mill/grind the front of the machine to be parallel with the quill. Now you can mount linear slides and a plate that grabs the quill at the bottom!
