I'm wondering if it's possible to add a receptacle controlled by Mach3 to turn on and off the router/spindle motor? Anyone know?

Mike,
You got ahead of me :-) We're changing over to a new Parallel port interface and on it, there are two mechanical 125vac 10 amp relays that can be controlled with the software with onscreen buttons and M-codes in programs. We're rearranging the front panel of the machine to accept two standard 125 vac receptacles. So, in the future it will be possible to control the spindle i.e. turn on at beginning of program and shut off at the end of the program automatically. As well as Vacuum sources, etc. Shop lights, :-) whatever one wishes to turn off and on. Actually there are 4 available software controlled outputs. Only two will have a relay pre-installed. The other two can be utilized by the addition of a solid state relay. On systems, using the closed loop feature, there are 8 available software controlled outputs. 4 on port1 and 4 on port 2 As well as 5 available software inputs on each.
Now, if you have a machine already, It has 4 available outputs, unfortunately there are no relays on board. To use these simply connect a solid state relay to one of the 4 to control whatever. Mounting a receptacle(s) in the front panel is at your disgression. It's possible to just route a pigtail from under the machine. Controlled by a relay. Always break the hot, never the neutral (white wire) Always use safe electrical practices. If in doubt, get some help from someone qualified. 125vac can be lethal.
Thanks, Ron

My Romaxx is hooked up like you're asking about. I have a closed loop system with the encoder board, so it already has relays ready to be hooked up to. I installed a 'pigtail' (aka, the cut-off end of an extension cord  ) and run the spindle (PC router) from that. Put an M3 in the gcode where you want it to turn on and an M5 where you want it to shut off. Dont forget to adjust 'dwell time' in Mach to give your machine time to ramp up to speed before it enters the workpiece. -Nick |
