the spindle / tooling arent a draw bar like on a bridgeport, they have
pullstuds in the back, which get grabbed by some kind of mechanism inside
the head, im still curious to see how it goes about doing it, I know its
spring tensioned and hydraulically released.
the amps look identical at a

Runaway is something i was worried about, and I still havnt determined the
culprit of why the Y ran off that last day the machine was in service in the
shop it was in. So far I know that the A and B signals from the encoder are
good, havnt tested the z, znot, anot and bnot yet, and I have to
Tonight I hooked up the jogwheel and one of the motor's encoders (100 line
and 2500 lines) to the parport, and with turning up the ferror in the ini I
can use it like a DRO, turning the encoders moves the axis readings. I was
wondering if i could just build an H bridge or similar switching

could get that feedback working directly from the encoders to the

I'm looking at the etch-servo config in emc2-trunk, and I'm not seeing
pwmgen.*.pwm-freq getting set. Does that mean it's left at 0, and pwmgen
does PDM?
