PMDX 414 Lathe Encoder RPM Measurements
« on: July 18, 2017, 08:04:31 PM »
Windows 10 Pro 64 Bit
PMDX-414 Rev A SN35466
Mach 4.2.0.3390
Plug-in 0.51.252
Firmware 0.58.205

I am testing a lathe configuration using the quadrature encoder for spindle speed measurement.  I can get spindle speed measurement to work using the index pulse, and using tach mode.  When configured for encoder speed measurement I get zero.

If I configure for tach mode and then switch to quadrature mode it starts working.  After shutting down Mach 4 and restarting it no longer works until I repeat the procedure.

I am using an Arduino to simulate a 100 line quadrature encoder running at 150 RPM.

I have attached the Machine.ini file.
