Variable feedrate
« on: December 12, 2011, 01:35:23 PM »
Would it be possible to have a variable feedrate based on an analog input signal (or from an PWM signal)? This would be very useful for use with an (wire) EDM, so that measuring gap voltage and feeding this information back to Mach3 as an analog signal (like 0-10 V) would adjust the feedrate properly.

Use an analog input to control the Feedrate Override.

It would work with analog But you also will end up with the FRO being controlled in small steps. Also it will depend on how fast you need the feedrate to react to changes.

Just a thought, (;-) TP

Ah, of course :) Thank you, didn't think of that at all.
