Hi Guys,
Me and my dad is building a Milling and Plasma Table.
The milling Part works fine.
I am running Mach3. I have connected up the relay as in photo attached but as soon as we turn on our 3 phase plasma cutter the relay blows( I test the relay by removing the signal wire and touching the ground, before the plasma blows it it clicks when touching ground, after it is blown I do the same but only the light goes on. if I power of the 5v and back up it clicks then only).
It blows the relay and Mach3 says limit switch triggered. (I'm guessing the faulty relay causes that).
Can you guys please help as this is our only issue left. I hope before the machine is complete.
