Hi guys,

I've taken the advise of m_c and added an USB controlled breakout board and an extra 24VDC power supply.
Tried to hook it up and got the drivers and limit sensors working, however the spindle doesn't seem to respond in Mach3.
The Chinese VFD leaves me puzzled as the only manual I can find is not for this model (FC300-4.0G-S2-B4C).
I'm hoping someone on here can shed some light on how to connect it to control the speed in Mach3.
