Hello,

I have my router table up and running, but now it is time to do some upgrades. I have been trying to integrate an arduino (mega prefered) into my mach3 setup using Modbus/brain. I want the arduino to just feed measurements back into Mach3 (Mach3 doesn't have to respond to them, yet). It would be nice to get the true speed of my spindle, build area temp/humidity, and water temp, etc. My current parallel breakout board does not accommodate this much additional information. I have found a few articles on this kind of setup, but it has still not been working for me.

I don't want to driver my table off the arduino just read different inputs into Mach3 for real time diagnostics. After a month of tinkering, it is time to ask the experts.

Any suggestions would be much appreciated!
