Re: Homemade MPG

I have a CAMM3 machine made by Roland. it has a pulse wheel that is manaual. when you spin it, the encoder wheel sends out pulses and moves the axis. the best part is that the machine has a readout so that it displays the distance.

I think it has 90 some pulses for each full rotation. there is also a pair of buttons for rapid.

here is a guy who has one.

you can see the MPG system, one wheel for each axis, and the readouts.

it is a nice machine. if you have a MPG, it is a VERY nice addition. especially when there are no handles.
