Steps for configuring Mach3:
1. Install and configure the latest plugin for PoKeys. In Mach3, under PlugIn Control / PoKeys Cfg.., enable and map encoder 1 to 4, which is MPG1.
2. Two text display methods can be used:
2.1You can assign text to be displayed on LEDs status.
2.2 Using a Visual Basic macro, you can use these commands:
SetUserLabel(1,"My")
SetUserLabel(2,"Message")
SetUserLabel(3,"for")
SetUserLabel(4,"CNC4PC")
Text can be formatted using visual basic functions.
