I brought up a question about using the KX3 motor pulley and belt on my SX3 to increase the spindle speed and was told it would work fine. I haven't done that yet, but it brought me to another question.

I'm told the KX3 runs the same motor as the SX3 so I'm wondering if the KX3 Spindle Control board ($95.00) will work in my SX3 and will that give me decent Mach3 control over speed, direction, and on/off ? Is it a very good solution?

The reason I ask, I remember hearing complaints about the syil conversions that used a controller to simulate pushing the buttons and it was slow and kind of a big patch. The KX3 doesn't operate that way does it?
