Guess need some where set what pin use to output speed?
Edit.: Ad pic of monitor of AXBB and looks like it knows that spindle are running 133.33 or 31% of 400 Mhz. So guess i missing something on MACH3 or what?
Check Analog is assigned to pwm in the plugin.
Got this off cncdrive forum:

"You can configure the spindle PWM and then on the AXBB-E Mach3 plugin page, in mach3 in the plugins menu you can attach the analog output to the spindle PWM, then the analog output will be proportional to the spindle PWM".
