How much PPR do you use on your encoders?

I'm using the USDigital method of PPR vs. CPR; CPR is Cycles Per Revolution and is 4x larger than PPR (pulses per revolution).

Option 8 also applies if you use potentiometers or absolute encoders in the place of incremental ones. A post below if you're one of those teams would be appreciated.

Depends on what it's for Are we talking drivetrain?

For drive train we use 250 or 360, whichever have or get that season. They're more precise than we can reasonably use.

We also use absolute encoders (analog, no PPR) for where we need repeatability from powerup to powerup (think elevators).

For shooter wheels, it depends on the size of the wheel. We prefer to use 4 minimum, more if we can get it on the wheel itself (hall effect or similar sensor).
