Title: Debounce in Mach4?
Post by: wmgeorge on February 04, 2023, 10:15:49 AM

I keep seeing references to debounce and  noise filter setting in Mach4 but in spite of a lot of searching and reading, where is this all located?   Using an older version of  Mach4 but is it all in a later one?  Using a UC400ETH and trying to setup Homing and Limits.

Hi,
de-bounce or noise filtering is property of the motion controller not Mach4. You need to look at the pin assignments of the UC400.

I use an ESS and the de-bounce is part of the ESS plugin PinConfig tab.

Thanks Craig, I swear it was in Mach3? Perhaps not, but my UC400ETH setup does not appear to have that setup.

It was in Mach3, but it was controlled by the motion controller plugin.  Same with Mach4. 
I think the ESS uses filtering per pin... (I may be wrong, it has been a while since I've used the ESS).  I know the HiCON has filtering on everything in one place like mach3 had.

 Your more than likely correct my  commercial machine was a Warp9 controller running on Mach3 and then 4. I had a PMDX 416 (with connection issues)  on this one and I thought it had those features... but I am not remembering.  Now this UC400ETH appears not, I should have gone with the Warp9 this time as Craig suggested...

Hi,
the ESS allows you to place filtering on each pin, it is the programmatic equivalent of a low pass filter. Each pin can have its own time constant.

If the UC400 does not have the same thing then add a low pass filter to each input for which it is required, a resistor and a capacitor, hardly rocket science.
