I have these two parts here http://www.cnc4pc.com/Store/osc/product_info.php?cPath=40&products_id=159
and http://www.cnc4pc.com/Store/osc/product_info.php?products_id=353

the only thing that works is the e-stop button, and when pressing the enable button and watching the mach3 diagnostic screen, one of the green squares lights up, but when I turn the wheel nothing happens... shouldn't it be possible to use the diagnostic screen to show me the signals from the wheel, I have measured most of the signals with ma osciloscope and there are coming signals from the c-22 board, the clock pulses coming from the c-22 board are maybe too weak 3,5Volts p-p (peak to peak), I have 4,88 volts coming from my USB port any suggestions?
