Hi, would it be possible for the C3D team to describe what the spinderella board is doing to the speed signal from the C3D controller (and what the format of those signals are)?
I am trying to use a C3D spindle/VFD with a different controller, and am unclear if I should keep the spinderella in line on the control signal or not. I can bypass it if I have to, but am curious what problems C3D is solving with the signal processing part of the spinderella, aside from adding the override tool change soft power button.
It looks like the C3D controller is outputting a PWM signal embedded onto a 60Hz AC-ish carrier, and the C3D spinderella is converting it to an ~8kHz +5VDC PWM to send to the VFD. Am I understanding this correctly? It was late when I looked at it with an oscilloscope so I may have missed something here.
Thanks for considering!
