Hello!
For the last couple of weeks, I've been trying to figure out why I can't get these to work...no luck, sadly.
I've moved my testing out of my printer and into a loose MKS Gen L board, Pins_Ramps edited so X&Y steppers CS pin is on 66&65.
Using the Stallguard example from the TMC2130 library, I get the expected result plotted, when reistance is applied to the stepper.
I connected up a meter to check the output from the diagnostics pin, connecting it to ground. I get a zero volts, ramping up to just short of five volts as greater resistance is applied to the stepper.
However, when I switch back to Marlin, I can't convince it to have any output on the diagnotic pin.
Hopefully, the attached will give away some stupid mistake I've made!
