Hi, thank's for the really fast answer to my problem. Yes, it sure works to do like that. What i tried to do was to assign hotkeys to axis 4 in screendesigner4.
It did work for X,Y,Z. But not for the 4'th axis. That one just continued to run after i released the button. But when i did like u told me, inside Mach3 it did work. Thank's for that. It must be some problem with the "communication" between Screendesigner4 and Mach3...
Anyway, this solved my problem. Thank u for a really nice and cheap CNC program / Olov, Sweden
