Controller board markings CNC-01 V2.0 170708
I have viewed the videos & read the introduction document
I have tried the settings I can find sp
$32=1
$30 & S-value max = 255
But I cannot even mark cardboard, plastic or wood.
I am sure I am missing something very basic, point me at some documentation?
Many thanks
Dave
