On the Planet-CNC board, the Mist, Spindle and Coolant outputs will require a relay to switch on those devices. Test one of those terminals with a multi-meter (Mist, Coolant, or Spindle). Each of these terminals have a GND next to the terminal for the device.
Test the voltage across the GND to the terminal with the arrow that you want to test. Go to the software and click on the device you want to test (mist, coolant or spindle) and note the voltage. If no voltage is output then check under the board to where the terminals are soldered. Re-test the terminals across the solder joints rather than the terminal block wire inputs. If you get a voltage, then there is a problem with the terminal block. If you don't get a voltage, then the board is not functioning properly.
I activated the output signal.. I did the tests indicated and I did not get voltage. I heated the welds of the three outputs and now works coolant but no mist or spindle, what should I do?
There are probably cold joints on the board at the chip or the resistors on the traces for those terminals. You can send the board back to us and we will repair and test the board.
