Need Help!- Router Relay doesn't stay energized

[Mr.Chips]

I am using a CandCNC Table I/O II Card, and have wired up the K3 relay (up to 20 Amps) to my router to have it turn on and off in the Gcode. When I execute the below code the router starts and comes up to speed then shuts down and the relay chatters, on the return to zero it turns on again and more chatter then it turns off.

Any suggestions?

Thanks

Here is the code

F 50
M03 (ROUTER ON)
X 5
X 0
M05 (ROUTER OFF)

Did you try energizing the relay without the router connected to see if the relay turns on/off with no chatter?

I just did and the relay acts the same way. There is an LED so i can easily see when it is energized.
Thanks

Tom at CandCNC sent me a new config file and after I installed it I discovered that the relay only chatters on and off the first time it is energized. And for as long as the PC continues to be on it will not do it again.

I also discovered that if I add a M05 in the Gcode and no more chatter as long as the PC is on.

So here is the sample code, just add M05 even before you turn the router on fixes the problem. A good and simple work around.

F50 (speed, IPM)
M05 (Router off) (This fixes the problem with chatter)
M03 (Router on)
G4 P2 (pause 2 seconds to let router come up to speed)
x 15
X 0
M05 (Router off)
M30 (Rewind)

Try this. In General Config, ad M5 to the initialization string. That way when you start mach3, it'll do an M5 the first time you hit the reset button. Then you shouldn't need it in your code.

That sounds like it would work. But where is it and what is it called and how do I edit it, and where should it be in the config file?

Ohhhh lots of questions

Hope it is an easy fix
