I have searched and read for hours, but can't find a solution to my problem. Hopefully someone can help.
I am new to CNC and everything has been going good. I recently decided to utilize 2 SSR's to control my spindle and flood coolant. I only want to turn the spindle on and off, not control the speed.
I wired the relays according to several diagrams I found. Using a 12V battery, they function as they should.
I have a camtronics box with 2 relay outputs connected to pins 16 and 17.
I have configured everything and can toggle the spindle/coolant outputs and get 5 volts.
Now the problem. Even though the relays are rated to trip as low as 3V, they are not tripping with 5V. Connect them to a 12V battery and they trip like they should.
Is there a way to increase the output voltage of these pins?
