Limit switchs

The servo tuning instructions say to get the encoders scaled correctly in order to proceed with tuning the servos. How do I do that?

You set the per axis ENCODER_SCALE parameters in the INI file to encoder counts per machine unit (machine units being inches or mm)

When I ran the PnCConf I put in all of that. But when I move the table the numbers are wrong. I went back and double checked the encoder, the two gears and the ballscrew. Does the problem lie in tuning the servos? Or does the movement numbers have to correct before I tune the servos?

It has to be correct before tuning.

How do I correct it?

When moving the axes 0.100 it says on the screen 0.0834 What is a way to get that to match before I tune the servos?

Did you command a move of 0.100" and got an actual move of 0.0834" ?
this would be expected without tuning

Normally you would check the encoder scaling and direction with the drives disabled
