Mach turns spindle OFF when plunges.
« on: September 27, 2014, 02:32:25 PM »
I have just fitted. new controller, the spindle starts as soon as I power up the controller ....I am OK with that ....

But then when I run gcode in Mach3 ...it positions the spindle ..plunges to the sub straight..,then the spindle stops..when it should be cutting.

Is this a Mach 3 setting which needs adjusting.

Thanks

Roy

You shouldn't be... That's very dangerous.

If Mach3 is turning the spindle off before cutting, what's turning it on?
It could be the active low setting of the output pin used to turn it on/off.

Thanks for reply.

I am not sure how/where to change that setting to what.

Can you please give me a clue.

Thanks
