Could I use the PWM Servo Amplifier to drive all 4 axes? I have had good luck with the encoders Kelling sells - I love that they have adjustable CPM. What encoders do you like? Anything else I need? Where does one get the connectors for your PWM Panel? One last question - how would you recommend going about adding a 5th axis? I could live with 4 axes for now manually setting a 5th axis (e.g. tilt - but 5 would be ideal). As a side note I have opted to upgrade the ACME screws to a ballscrews as the first step.
