General Mach Discussion / eCut v1.1 - Spindle Speed Help needed (mach3)
« on: March 28, 2020, 02:40:55 PM »
I have an eCut motion controller, v1.1. It is connected via ouput pin 7 and the 0-10V to an Automation Direct GS2 VFD. I have spindle control working (speed and on/off) from Mach3, however I am stumped on how to get a realtime RPM reading from the board.
The SP+,5V, SP- and gnd are being used with an NPN sensor (wired per manual), with a magnet on the spindle head. The eCut features a diagnostic LED for the speed sensor and it does flash as expected in sync with the hall effect npn that is triggered from the spindle. I have tried a number of configurations, but can't seem to identify one that works as expected. Any tips from folks that have a working confirmation with this board on how to get an RPM reading?
