you could still use mach, use a second parallel port with pins 2-9 as inputs and have a common feed to the turret and eight switches (electronic or otherwise). Use the inputs and write the code to look at each position/input, it would be pretty easy code to write.

click tab on your keyboard and check that your "slow jog rate" is 100%, if not click on the box and change it.

in it's simplest terms, the softlimits are the distance from the machine coordinates (usually the home point) you wish the machine to have as a limit on each axis.

it would be easier to ge a pulse signal and get mach to do the threading

Barrafuldi use one in there 8 station toolchanger, and it's been known to fail.

there will be a fair bit of work to get them to fire at the same time anyway (a read delay in the macro possibly). An 8 position rotary switch would be the easiest to work with.

reflective disc and sensors.
