Encoder assistance please

[anoel]

Ok, I finally figured out that my encoders are 250CPR

Now, I'm running a 16TPI Screw Direct...

I'm using TurboCNC, I'm trying to figure out how that 250CPR translates into inch units per step so that I can run these motors soon.

My first experience with encoders so.... This is the big question.

So an explanation on how to do the math would be appreciated.

Thanks

Steps per revolution = 4 times CPR
In your case 4 times 250 = 1,000

Counts per inch = TPI times Steps per revolution
In your case 16 times 1,000 = 16,000 steps per inch

Each step is 1 / 16,000" or 0.0000625"
