I have been trying to set up a custom screen, but am having a lot of trouble. I understand kind of the screen 4 program, but I am dead lost on how to actually program buttons to do certain things. I would appreciate some help or a push in the right direction. I want to re edit a button from the blue probe screen to turn on or off my router and shop vac. Right now I have them as M3-router and M7-vac. Could someone please help? Thanks.
