ok, but then how do I enable a path from the 12 volts being fed to ena+ to ena-. ditto 5 volts to dir+, which should from what I'm reading, send 5 volts to the dir- terminal. The two supplies are separate, sharing a negative common with +12 volts on ena+ but nothing, well 60mv maybe on either dir- or ena-. The pwmgen.0.0.value is 3.1 and growing very slowly, identical to pwmgen.0.1.value, and I can see the pwm with the lalscope at either output. But I've no clue how to verify its getting to the spindle i/o other than looking at the right gpio pins on the 5i25. so obviously I do not know what I'm doing Ok, that explains that. > In addition to setting hm2_5i25.0.7i76.0.0.spinout (to some fraction > of the current scale value) you need hm2_5i25.0.7i76.0.0.spinena set > true to get analog out It is, set true by starting the spindle. but no output at spinena> > > I can see the other pwmgen.1 on its p2 pin, so routing that to the > > pwm-servoamp in the G0704 will not be a problem.
