The script for the Cryo Payload motor driver for Phytron, which I inherited from Nishimoto-san, has been officially incorporated into MEDM.
The modifications from the original file are to correct the name of the script as Pico and to delete unnecessary files.
It also supports stopping.

Original file:
/users/nishimoto/phytron_stepper_motor/picomotor

Destination:
/opt/rtcds/userapps/releasae/cds/common/scripts/epics-motor-control/phytron

Create a Phytron motor OVERVIEW so that you can check the operation of the motor.

I plan to create another one for adjustment.
