Thanks for the replies. I just made the changes shown below:
univpwm_io.hal ------------------- ... snip # connect index pulses to motion controller # do these when index pulsing is figured out # This has been commented out pending changes to the # driver to work with the canonical encoder interface #newsig Xindex bit newsig Xindex bit <- new #newsig Yindex bit #newsig Zindex bit #linksp Xindex <= ppmc.0.encoder.00.index linksp Xindex <= ppmc.0.encoder.00.index-enable <- new #linksp Xindex => axis.0.index-enable linksp Xindex => axis.0.index-enable <- new #linksp Yindex <= ppmc.0.encoder.01.index #linksp Yindex => axis.1.index-enable #linksp Zindex <= ppmc.0.encoder.02.index #linksp Zindex => axis.2.index-enable ... snip And it works just fine - for X anyway. Jon - I'll have to study your link. I have some spindle issues to work out. I have an SSR for each: spindle brake, forward relay, reverse relay, high speed clutch, and low speed clutch and a stepper motor and limit switches for the variable speed pulley mechanism. Either that or go with the VFD. Either way presents new territory and hardware.
