Analog inputs through MODBUS to control overrides?

[eMTea]

Hi!
Is it possible to use analog inputs through modbus, to control feed/speed/rapid overrides?
Or use a rotary encoder, maybe through a micro controller, to do the adjustments or simulate + - button presses?

You can use any Modbus device. For serial Modbus I use Arduino Nano, for Ethernet the Mega is needed. (The Nano does not have enough memory for Ethernet Modbus.)

OK!
But in the UCCNC software, can I map the analog values to a VAR, and attach that var to the overrides?

It's more easy. If you use an Arduino then it will return you 0..1023 from the analog input. You need a macroloop which scales this 0..1023 to 0..300 and write the value into the FRO or SRO field. That's all.

Great! Thank you!
