Does anyone have the parallel port working with Mach4. Specifically with the charge pump activated? I'd be interested in comparing configurations.
I have been in contact (for several months) with NFS support and they have confirmed that (as I observed) the charge pump signal from Darwin initially comes up and then fails just after Mach4 startup. It requires a toggle of the enable / disable screen button to get it going again. This would not be a big problem except that when if fails the DRO's still change but the axis' do not move because the lack of charge pump signal has disabled the drives. So then the disable/enable trick has to be done and a re-calibrate is required.
In my latest exchange with support they have indicated that they have no (financial) interest in working further to correct the issue and suggest I purchase a motion controller instead. Fair enough I guess but it makes me wonder why they continue to sell the parallel port plug-in (Darwin) when it has this bug. Then it makes me wonder - if they have sold more than the one I have - what have others done to make it work. Maybe I've missed something.
So, Is the parallel port finally dead?
