Hello everyone, I have a new project for you! I have been doing alot of research on Trinamic TMC2660 stepper driver chips as are being newly used on the Azteeg X5 GT, and I see tons of potential with using their StallGuard feature paired with STI connection as a great and simple replacement for endstop switches on most machines.
I wanted to throw it out to the community as I myself am a bit rusty on the specifics of smoothieware and whether or not it would be feasible to make this a reality, but I certainly see the potential and absolutely need this feature to exist as to simplify the machine's wiring.
I came upon the "Smoothieboard Advanced Driver Support" page and it got me thinking that if smoothieware is already reading the SPI pins and stopping the machine's movement in the event of a StallGuard collision then it could also be rerouted to making the event of a StallGuard collision act as the triggering of an endstop switch.
Thanks everyone, and I hope that we can figure this out!
