I'm working on bringing a fairly large panel router back in line after a bad retrofit. All the limits on the machine and the spindle RPM sensor are NAMUR sensors, meaning they change amps rather than volts and I've got 2 sensors per axis, so 7 NAMUR sensors total.
So it's great I figured that out, but I'm a bit clueless on some basic electrical principals, but I can make analog circuits just fine.
How can I get the amplitude change to register in Mach4? If you have a basic circuit diagram you can point to, I'll puzzle the thing out, but I'm a bit at a loss right now.
Controller is ESS Smoothstepper via C11G and C25S breakout boards.
