I am setting up a Paxton Patterson Sherline cnc mill to run with UCCNC and UC100. I have the pins set for the 3 axes and can move the axes with the program. My next step was to make the spindle turn on and off with the software. First off the mill has a switch to set Manual or CNC. The spindle also has a separate ON/OFF switch. If Manual is set I can run the spindle using the ON/OFF switch. If I switch from Manual to CNC the spindle stops and the ON/OFF switch has no effect. I am using pin 16 to operate the spindle. On the spindle screen I have set Spindle Relay Output Enabled M3 relay to Pin 16 and checked 'Active Low'. I attached the UC100 to the mill. When I power up the mill, set the mill to CNC and set the spindle to ON, the spindle motor runs. But I can't turn the spindle off with the software. On the UCCNC spindle screen if I uncheck 'Active Low' the spindle stays running. Am I doing something wrong? Am I missing a setting? On the Diagnostics screen Pin 16 stays dark no matter if 'Active Low' is checked or not.
