Nan - voltage

also, it dosent sort its self out..once it boots with a nan..

it stays nan until you reopen linuxcnc.

if u run with nan. it crashes.


or from memory. if mode 0.

never reaches arc okay. and dosent do anyrhing but pop a hole in stuff.

Does it ever show a nan at some later stage or only on startup?

only ever on startup.

Phill. Not sure this is relevant but recently I have been playing around with denounce like this:

setp scale.0.gain 60
setp lowpass.0.gain 1.000000
net spindle-velocity-feedback-rps => lowpass.0.in
net spindle-fb-filtered-rps lowpass.0.out => abs.0.in
net spindle-fb-filtered-abs-rps abs.0.out => scale.0.in
net spindle-fb-filtered-abs-rpm scale.0.out => pyvcp.spindle-speed

Using 2.8 on a P/port with lathe for spindle display from a 100 slot disk with opto's

That is I have seen nan in the display with some odd setting in the gain.

Thanks Clive, it is a bit different. We are getting an inf (infinity) from the encoder on startup and because we do a bit of math with it we ended up with a nan.

still no nan

Great, thanks for reporting.

It would be nice to know why it does appear. When I get a spare minute I may pose the question on the developers list.

im quite happy to guinea pig things, let me know if you need anything

I'll keep that in mind.

I have pushed those changes to 2.8 and master.
