How do I disable the drive? When moving the table by hand using an indicator. I move 0.100 and get 0.375 on the dro. When I use command to move the table 0.100 the dro says 0.0834 and the indicator says 0.007 of movement.

The drives should be disabled when in estop
(but the DRO should still work)

OK I moved 0.100 on the indicator the dro says 0.4172. I am using a digital indicator.

Is this reliable?

( does moving another 0.1" add another 0.4172 to the DRO reading )

If so the scale is off by more than a factor of 4

This may be because you have not considered that a quadrature encoder
will have 4X its PPR counts per turn (a 2048 PPR encoder will have 8192 counts per turn)

Thank you. I looked at the manual it said one 360 turn was 2048 I never noticed the word quadrant. I just set it by the 2048. Thank you for the help. I multiplied the number in the INI file and it is close now. I'll tune the servos now. Again that you for the help.

I am at the point I am getting ready to do the PID stuff. I needed to home the axis. When I home the machine and it hits the switch I get this

Z axis. Joint 2 following error.
Y Axis. Joint 1 following error.
X Axis. Joint 0 limit switch error.

How do I fix this?

Thank you.

Jeff
