I am in the process of building a machine, a simple xyz gantry.
The machine runs on EMC2 using linear scale / BLDC servo loops implemented in external hardware. EMC provides control signals step and direction and is configured a ssimple stepper motor controller.
Machine behaves quite nicely. It recognises end of travel limits. Test plots ( in lieu of actual machining ) comes up well.
The linear scale generates home index pulse.
I understand that EMC allows a motion control interface card to recognise the pulse.
Is there a way of interfacing the pulse NOT A LIMIT SWITCH to be recognised as home location in absence of such a motion control card.
Any suggestion is welcome.
