@Laz
I'm using PWM with no prob
have got a wrong numeration too

May I ask how did you hook up the VDF to XHC  to control the spindle speed and your Mach4 config for it??
Thanks in advance

Hey guys, I've had a bunch of people messaging me still about using this card with MACH4.
With the latest builds of MACH4 this plugin is currently making the machine jog without any input. It's dangerous and XHC hasn't made any corrections in some time despite numerous attempts to contact them.
Please do not buy this controller to use with MACH, there are a lot of good options with actual support and development.
I will update this thread if XHC decides to reach out to us and correct the issues.
joeaverage listed some controller alternatives please use one of those.
