424 relay

(1/2) > >>

john mitch:
hello i am new to cnc i have a 424 i am having a problem with the output relay. it will turn on with the m3 command but will not turn off with the m5 command. the g code gets stuck on the g5 command and the relay stays on. is there an output signal for spindle off that i am not seeing?

Steve Stallings:
Does the G-code program simply continue running without turning the spindle off, or does the program actually hang?

Is the m5 command the last line of code in the program?

john mitch:
it just hangs on the first g5  there is more code after that. i am using this as a plasma table and i am using the spindle start and stop as the torch control on and off. is there a better way of doing this?

Steve Stallings:
Did you mean after the first m5? A g5 is not a valid G-code command?

john mitch:
sorry i did mean m5
