My name is Mark, and I am new to CNC. I have been playing with Mach3 for a few days now, and I'm having some trouble with it. The Mach3 program recognizes the licence and the software that came with my machine(TL 501 BDN). I have not yet hooked up the machine to the computer. My first (of many) problem is that even after watching the "install video" several times, I still cannot jog the axes. When I press the arrow keys, the DRO's do not move. The numlock is off. Also, in diagnostics, I have six red LED's lit up(underneath the button for 'Settings Alt6') and I do not understand what they refer to. Can anyone help get me started?
