John, have you been following Stig's MH 400E conversion to Mach3? Very different approach in that he ripped everything out, and is not using the gearbox at all.
This approach makes sense if he is going to only mill aluminum with small cutters, and he don’t need the horizontal spindle. The spindle is rated at 1.5Kw, but this is what a true 1.5Kw spindle servo drive looks like.
