so the shack has these cute little boxes with nifty electronic crap in them. I want a different way to send the spindle speed command to my lathe from mach3 so I figure I would buy it and try out my luck. the BOB (c11g) DAC seems to be unreliable for threading and this was 20$. ;D
anyone ever seen these?

in motor outputs the spindle would be set to some pin# on this and port 2 through the usb address?
spindle setup would be set to PWM and then it works? lol

Almost certain the only way you will get that to work is write a plugin so that Mach can communicate with it.

huh :-\
well what about this thing from cnc4pc...

what do people use to get analog out of mach?
I love my Kflop/Kanalog but I don't have another 500 to pony up anytime soon. :'(

Thought you already said the CNC4PC board was unreliable?
I have been using the CS-Lab controllers recently, they have analogue I/O on board for spindle and overrides etc.

I have the big C11g BOB. the analog output on that has always been weird for some reason. instead of buying another spendy board I figure a new added on board for the spindle alone would be snappy.
when you say plugin are you saying some thing like a C code file?

Maybe the standalone board uses a different method of converting the signal to an analogue output than the integrated one, I have no idea. Personally however if I was unhappy with one of them I would be trying to get a resolution from the vendor and if that was not possible then I dont think I would be considering buying another from that same vendor in the offchance that it may be better. Of course that is just my thoughts, I have no experience with these products at all so cant say whether they are good or bad.
I have used a step/Dir to analogue board from Peter Homann and it worked very well and was very linear in operation but that is the only stand alone board I have used for spindle control.
As for plugins, C++ I believe it is, but it is beyond my skill-set so really I have no idea.
