I have a g0704. I recently picked up a DMM Tech 3 axis 400 W AC servo kit to convert it to CNC.
Unfortunately, before I got a chance to install it, the motor died. It seems like I'm not alone in having a dead g0704 motor. I thought I would take the opportunity to add control to the spindle of the mill. Fortunately, the breakout board that came with the kit has spindle control (see page 7 of the manual).
My question is which motor and drive folks recommend. On Hoss's website, he recommended a GS2-11P0 1 HP 115VAC drive and a MTR-001-3BD36 1 HP 3600 RPM 3 phase motor. As he points out thought, the motor is huge and relatively low RPM.
Is there a motor-drive combination that would deliver as good or better performance as the g0704 stock 1 HP motor for less than $500 (preferably substantially less than $500)?
Thanks.
