Hi all ,can anyone explain how to connect the plasma torch on off switch to the breakout board so mach can controll it?im not very electronicly minded so pictures or diagrams might help. ive just built the machine on a watch you tube basis but i cannt seem to find anything on the subject.

hi all just found a breakout board with a relay already installed should sort my problem.cheers Nigel

So I'm gonna ask the same question since Nigel figured it out, but I haven't.  I have a TB6560 BoB with all the steppers working through MACH3, but this question is the last sticking point for me.  How do I physically wire from the BoB to my Plasma Cutter, the "switch" connection on/off button to get it to turn on on command from MACH3 via the BoB (Break out Board).

Thanks in advance for the help.

Hi i havent yet received my new board yet but have found this link that might help. let me know if you get your torch going  cheers Nigel http://www.cnczone.com/forums/diy-cnc_router_table_machines/149260-gecko_540_relay_wiring_mach.html
