Hi all,
I have read various posts on these boards but have not found any related to my problem.
I need to connect an inverter, where I need an output to turn it on and a 0-10V control for speed.
I have set in MACH3:
Spindle setup-> motor-control-> flag use spindle motor output, flag step / dir motor
By checking the diagnostic tool and activating the spindle, a voltage of 10V appears on the AV terminal which can also vary according to the set speed, and this is fine, but the FWD-out1 output
it never changes. (The FWD-out1 is decoupled, so when it should be active there is a GND) connecting a led between + 5v and FWD-OUT1 never turns on)
I would like to understand how to configure the part relating to STEP-DIR -> spindle, because I have tried various pins (different combinations) but without positive result.
I also worked on the OUTPUT settings, but without success.
In short, to conclude the 0-10V work and are there when I turn on the spindle, but I was unable to activate any output.

Another question:
My stepper drivers have an ENABLE input
to avoid motor overheating, how can this input be used? My BL-USBMACH-WS-3.25 board does NOT have outputs to drive the enable of the drivers.
Thanks in advance
