How to set up for Mach 4 to display RPM
« on: November 21, 2015, 06:21:20 PM »
With Mach 4 and the SmartBOB-USB, I see the spindle input toggling in both the Mach 4 diagnostic and the SmartBOB real time port display when I run the spindle but there is no RPM display in Mach.  I suspect I'm missing some set up step.  Also, and presumably related, I don't understand whether Mach is using the input to find the RPM or whether the plug in is finding the RPM and sending it to Mach to display.  Thanks for any advice.

Spindle RPM calculations from INDEX input happen in the device and/or plug-in, not in the Mach4 core.  This feature has not yet been implemented in the SmartBOB.  It is on our implementation list, though it may not make it into our next release.  If it doesn't, it will be in the following release.
