Re: AC drives
I think they're referred to as 'written pole' motors.
You're virtually 'writing' every pole with a pulse of
current.

Re: replacing feed screw with a hydraulic cylinder
I've thought about hydraulic drive CNC for years. This may have
already been discussed but my idea is to use a closed system with
single shot pistons powered by solenoids or a motor driven cam.

Re: G-code interpreter/stepper controller
Hi:
Take it from me, really, if theres one thing I KNOW its that 10,000 steps
a second will never be overkill. 25000 seems acceptable to most, but to
really please most, you'll need about 50,000.

Re: tkemc for win32 platform
Great to hear you have the gantry machine working with EMC.
The software has high enough performance to work well with
the high speeds and accelerations of large gantries.
