Thread: one lead screw or two
[QUOTE=E.V. MacHine;23456]Same lines I'm thinking along. Means dedicating an extra axis, though, and I'd like to have the option of retro-fitting a rotary axis (sometime) later - so a 5-axis system, then? It'll need a 5-axis break-out board, to start with. (How do you add more axes? Does it need another com/lpt/usb port; EMC supports up to 9 axes, apparently... ) and a separate driver for each motor. And that's it??
Yes that's right, driver and motor for each. Unless you drive both the X screws with one motor and some timing pulleys / belt.
The parallel port has enough outputs for 6-axis if you don't use them for anything else, such as spindle control. A 5-axis breakout board is probably your best bet...
