Serial port feedback from welding module. Help.
« on: January 06, 2020, 01:04:50 PM »
Hi guys.
I am running an automated fixture inside my laser cutting machine using the AXBB-E controller on the Ethernet port. I advance a metal strip through a weld stage and then the part is cut out with the laser. Occasionally the weld fails, on a bad weld the weld module has the ability to output a signal via a serial to usb cable which should make it possible to re-issue the weld command and try again rather than produce parts without the welded bit.

I think this can be achieved using modbus but I am clueless here. How can this external signal tell mach3 to repeat the last line of G code (weld command macro).

Any help please !
