NEW BUILD, need help with e-stop in tklinuxcnc

Are you saying the GUI never launches?

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

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

Hello friends, thanks to everyone for the help. Unfortunately, it didn't work out, and after two days, I gave up and looked for another solution. I stumbled across an Arduino in my boxes and decided to go with UGS on Raspberry (VNC) & GRBL on Arduino. Everything worked flawlessly right away. I'm satisfied. Thanks again to all and best wishes.

Thanks,
Dragan
