Andy thx for the long and detailed post.

I set up mach acording to those settings but im not getting any voltage out from the board, well atchualy im geting 0.02vdc wether the spindle is on or off but i guess that could be considerd 0v, if i shut down all power to the BOB and spindle board and unplug the P port it does go to exactly 0v so i know its not my meter thats faulty.

coupple of quick questions: 1 In the outputs tab do i need to set an output to the same pin (2) as i set in motor outputs spindle box, or is just seting the motoroutputs spindle box enough to get it to give a signal to the spindle board?



2 In the spindle set up tab under ports and pins theres 2 boxes marked "PWM Base freq" and "Minimum PWM" do i need to type anything in thease boxes or do they have no affect when its set to step/dir?

thinking about it i guess i should double check that i have it phisicaly wired to pin 2 and not another pin!



regards
Simon
