I would really appreciate a little poke in the right direction on this.
The problem I am having is that I can not for the life of me figure out how to get Mach 4 to display my spindle rpm. I can see that mach/pokeys is seeing the spindle index pulse on the diagnostics page but I have no idea how to get this information displayed on the 'current spindle rpm' dro. I'm sure its something really simple but I have no idea what I'm missing.
The setup I'm using is a pokeys 57cnc and I'm feeding a digital pulse to it from an arduino (this is a simple test setup so that I can see that mach is seeing the index pulse).
many thanks for looking and any advice you may have.
