these would seem to be bugs in that I can’t get them to work as documented.
The saved position function does not work if there is only one entry. Add a second entry and it works.
The Show Last Position function does not update. Move the laser to home with the option turned on and th red dot does not move, jog the laser any direction and it does not move, turn it off and on and it stays in the same place.
This is running LB 1.0.0 on a MacBook Pro/Mojave/RDL-4040 Laser/Ruida controller
