Hello, all, I just added a DAC for spindle speed control to my Bridgeport. For years, I just had forward and reverse contact closures to the VFD and a manual speed pot. Now, I have a DAC channel from EMC to the VFD. I can start the spindle with an MDI entry like M03 S2500, but when I try to start the spindle with F9, it sends the spindle forward contact closure, but the DAC had been reset to zero.
Is there a way to make the F9 key use the last spindle speed setting? (In other results, I have been doing a bunch of rigid tapping on 2-56 and 6-32 holes. The only problem I had was finding out that my $8 spiral-flute taps are not good for deep holes. They bind up. A spiral POINT tap goes through like butter. 1000 RPM for 2-56, 800 RPM for 6-32. My only problem is all the reversing makes my VFD get overheat alarms, even with a fan on it. I probably need to get a bigger VFD.)
