Does anyone know how to get CNCJS to control the spindle speed?

Does anyone know how to get CNCJS to control the spindle speed? I can not for the life of me get it to control the speeds. I have R7, Tinyg and the VFD.

Thanks for all your help. Also Merry Christmas.

I’m not sure where @Brandon_Satterfield got with his experiments with this. Would love to know though as I have the same setup!

@Ben_Delarre Im going to be looking at this problem again this coming weekend. If I get anywhere I will let you know.
