On my G0704, which has the OEM motor I'm abusing, I've been studying up on how to get a 12 volt enable signal, which currently is a sparkfun contraption driven by a std bob signal.
But with the 7i76d, can I feed 12 volts into the pin a vfd's 12 volts would normally drive, ground the Spindle- terminal, and get the 12 volts for spindle enable from the Spindle Enable+? Page 18 seems to indicate I could source a few ma that way. I'll be using a different pin for the pwm signal that amplifier needs, probably the pwm will show u on step or dir 4, on tb3? Obviously this is a bridge not crossed yet. And in investigating where the pwm might show up, there isn't such a critter in the 5i25 as programmed for the 7i76d! Looks like I will have to load a software pwmgen and feed it out of a gpio on the 5i25's p2? Why is this not an error?: loadrt hm2_pci config="num_encoders=1 num_pwmgens=1 num_stepgens=4" I'll sort it, but tis a surprise that no pwmgen shows in the halmeter menu. Or is it there, and completely gobbled up by the builtin spinx1 in the 7i76d? Ack the 2 pass output yes its there. Must figure out how to access its raw output... For the pico amp the analog out on tb4-2 that would feed a vfd's analog input is not usable. Looks like I'll need a software pwmgen feeding a gpio on p2, And feed both pwmgens? Hummm. Advice needed Peter. I don't think I'm seeing the whole picture. Thanks. Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
