Spindle RPM - Filter not working with encoder and 7i76

Doing a lathe conversion and only today realized there's no RPM readout in AXIS (not sure why that wouldn't be a standard kind of thing)

Anyway, found the pyVCP and read through the basics, copied the samples and create a bar-graph for my spindle RPM

Except it's not working

I've got a quad encoder hooked to TB3 and it's giving signals back (no index just quad) but when I look at the HAL meter for spindle-rpm-filtered there is no feedback at all (just spinning the encoder by hand)

If I change the meter to look at spindle-vel-fb-rps I get a result from the encoder (+/- both directions) as well as using spindle-revs (just a counter for location but shows the encoder is working)

Maybe the "filter" set too high and it can't see that I'm spinning the encoder but I can't find a filter value anywhere that looks related

Thanks

Update
Using the routine from PNCconf to add the RPM display I now get a value showing on the screen. I'm still trying to see what it changed and how it's different from what I did following the instructions on the pyVCP site but it's at least giving me something. Not the right thing and it's bouncing around quite a bit but at least it's a starting point

LOL
Well for my poor old brain it's the indicator that I didn't punch in the correct speed in the first place

Almost embarrassing to tell you how many times I've been cutting away and look at the cut and go "that seems awfully slow/fast" and then check the rpm and go "oh, because it is slow/fast and I didn't change the speed in the program when I did whatever change"

It's only me that's slow

Here's what I picture happening to me. Just when I think I'm having a good day in the shop (hobby butcher remember)
It's running at 700 rpm for whatever dumb reason I have, I see it as too slow but I think I had it set at 1000 so I decide to bump it up to 1300...
Anyway I added the indicator (pyVCP widget) and although I haven't gotten to the actual turning on of the spindle yet (re the other thread on encoders and gear changes your helping me with) I'm hoping next weekend I should be able to connect the new control board on the desk here to the machine in the garage and get movement again
Thanks again
