Yes one of the SainSmarts. Zero opto's in the outputs. Nice, dead smooth spindle speed regulation w/o the opto's lags and distortions. > If so its probably easier for me to make a bitfile for that > (and safer than kludging up some adapter) No need to Peter, I am 99.9999% sure the problem has been solved, see my previous 2 posts.
