| - | I usually set the 88hz second order filter, because I found that it does not usually need a pid change. | + | |
| - | + | ||
| - | The hardware filter seems to not work well on zero setting ( 260 Hz), but it works fine on 1 and higher( 180 Hz). But I am not sure if changing from 3 to 1 would allow a perceivably improved response. | + | |
| - | The hw filter lag saving is 3ms from 3 to 1 , and 2ms from 3 to 2, but I am not sure if it translates to higher usable D term, and hence improved response. | ||
| - | You might get higher response by turning off the D term filter in the pid file, also, turning the motor filters off could reduce lag. Both of this filters filter less than the software filter, so it's possible that they are largely redundant with the software filter on. | ||
