I am hoping someone can help!! I have a Sherline mill with an easy cnc 3 axis control board. I purchased a cnc4pc c6 board to control the spindle. I have hooked up every thing in accordance with the instructions provided and am having difficulty getting a 0-5vdc signal from Mach3. I am currently running the latest version. I have tried both the step and dir route and the PWM route to no avail. I checked the enable step and dir box and assigned pin #16 to the spindle on port 1. I set the feq to 10 and 0%. I set the pully to 10,000 rpm and ratio 1. I have tried with and without low active checked. with it checked I get a steady 1.5vdc when I type m3 s10000 in MDI screen. When I vary the speed the voltage stays the same. When I atempt with low active I get a mv reading that varies with speed but the voltage is to low to get any thing from the 0-10vdc out put on the c6 board. I can not seem to get Arturo to answer my email and frankly I can't say it is his problem untill I can figure out why Mach will not provide a 0-5vdc signal? I have searched for several days on this form and Mach's forum and have found people with simmalar problems but no solutions given? I tried Hoss's settings but they didn't work for me. Can someone please help?
