Spindle Speed Issues.

[blowlamp]

I'm having a problem getting things setup as I would like them on my screwcutting lathe with release version 2020-02-12.

Under Settings > User Interface > Speed:

Selecting From Index only displays spindle speed correctly up to about 350 rpm, at which point the reading freezes until the speed is lowered. Selecting From Encoder gives a good rpm reading up to my lathe's max speed of nearly 2400 rpm.

However, selecting From Encoder also results in a minus rpm reading (eg -1450 rpm) even if I try all Encoder/Synchronization combinations under Settings > Input/Output > Spindle, including selecting Reverse for Encoder PPR.

Everything worked OK under TNG v1

Thanks for looking.

It seems that "Reverse" setting is ignored. I'll fix this for next version scheduled for this Friday.
However this should not affect operation, just display.

Did you also get the speed freeze at around 350 rpm?

Many thanks.

What is your "Index PPR" and "Debounce" setting?

What is your "Index PPR" and "Debounce" setting?

Index PPR is 1, (Encoder has 100 slots) and Debounce is 1000.

Index pulse is shorter than 1000us (debounce value) and filtered. Lower debounce setting or turn it off (set to 0).

I set Debounce to 100 and it seems to be working now.

Thanks very much for your help!
