Hi there,
I have a setup with MACH3 where it should send a PWM signal, which will be converted by a digispeed board into a 0-10V analogue signal for my motor drive, but all I am getting out of the digispeed board is 0.1V max.
I've tried adjusting the attenuation trimpot on the digispeed board but it doesn't seem to do anything
Does anyone know what could be wrong here?
Just to be make sure I am testing the right thing, if the output from the digispeed board isn't connected to anything it should still send out the analogue signal, correct? I am just plugging my multimeter directly into the output on the digispeed board and getting the 0-0.1V readings.
Thanks in advance,
Phil
