Why my 3D printer head (PH40) goes into Stand-By mode while working

The printers are going into standby and eventually shutting off because they are not receiving the correct signal from UCCNC that the machine is running. This is a very simple fix outlined below. 

1.) Define pin outs in UCCNC –> CONFIGURATION –> I/O SETUP. On the left hand side you have “Current hi/low”. Those two pins should read “16” and “1”.

2.) Define pin outs in UCCNC –> AXIS SETUP –> SPINDLE. Bottom Left you have “M3 relay pin”. Change those values to “0” and “0” and uncheck the “spindle relay output enabled” if it is checked.
