Hi Nuri,

Yes it is. Use one of the enable outputs, say Eanable1.

Cheers,

Peter.

Just remember Nuri that an output from the PC does not make an EStop. Generally speaking an EStop switch should remove power from things that move (by removing mains power from your motors power supply.) As Peter mentioned an enable signal from Mach is a good way to let your controller know that Mach is in an operation state; but you should not depend on that for an EStop.

Hi Jeff,

Thanks for the correction. I read it that Nuri was talking about pressing the Mach3 Reset button, rather than an external EStop button.

Cheers,
