Hi all,
I have recently finished building my cnc router it is controlled by a Geckodrive G540 and Mach3 software .I have recently purchased a Opt laser kit PLH3D 6W XF . I have spent many hours trying to get it working but to no avail any help would be brilliant.I run the VFD manually so I intended to use spindle run / speed through Mach3 to control laser output.There are five wires going into laser White Analog input 0-5V , Grey TTL in 0-24V , Yellow Analog / TTL ground ,Green ,ground ,Brown Vcc 12-24V .i have connected yellow to pin 7 on main terminal block on g540 ,White to pin 8 ,and a blue spur from white wire to pin 9 .The way I understand it the input is either TTL or PWM so one wire will be redundant.
I will attach g540 and laser manual if requested .but they are available on websites.many thanks for looking.regards Phil.
