New Mk3/4 controller kit build - Servo Issue

[Zeusguy]

Need a little HW/SW guidance with troubleshooting since servos are not actuating properly.

I recently built the Mk3/4 controller kit and running TNGv2 SW Version 2020.03.14.

Test Scenario - From TNG, I select File/Generate/Square and then specify size.

Results – Servos make about two rotations and stop but stay energized through the X and Y duration; i.e. servos stop before screen simulation stops.

I have checked my connections and have had the same test results with 3 different sets of servos.

All help is appreciated.

Have you set the steps / per mm in the control

Issue was a wrong motor driver dip setting...
