Does the sim/tklinuxcnc config start OK? That uses the same loop.

github.com/LinuxCNC/linuxcnc/blob/master...lib/core_sim.hal#L46

gui is launching i cant move the stepper with arrows because i am locked and i can not turn the machine on

Are you saying the GUI never launches?

import linuxcnc and hal into the Python script, then create HAL pins to receive the spindle commands from HAL.

Load the Python script at load-time with a "loadusr" command in the HAL.
