MACH3 is starting the router on its own... Scarry!!!!
« on: February 29, 2008, 09:12:26 PM »
Sometimes MACH3 is starting the router on its own. I am afraid one day it will happens when I forgot to put the switch on OFF and when I change the bit.
I cannot figure out why it does that. I review all my settings and cannot find anything. That happens so far always when the controller is ON and after I did not touch Mach3 for 10-15Min. Is anybody have a suggestion?
Thanks,
Bruno

You will have to give a bit more info, also I am presuming you are meaning the spindle starts on its own, or do you mean the axis start moving?
 If its the sindle then info on how it is normally ativated would help, ie is it a relay that switches it on, do you have a custom macro or use a brain for this? any other info you think might be usefull as well.
 Might also be an idea to attach your xml file and any brains or macros that you use for the spindle.

If it's your spindle please please please replace the switch with a no volt dropout switch, spindles should ALWAYs be on one of these, even if the spindle is not started by Mach.
Imagine if you had a power cut, it goes dark (night) and you fumble around trying to get out of the workshop etc or your trying to find the spindle motor switch and then the power comes back on and your hands in the way. Or your not even in the shop when the power comes back on.
It has happened and will happen again.

For this reason the Mach manual recommends that you have a no volt dropout switch between the relay controlled by Mach and the motor.

Sorry if I sound a little over the top but I've seen it happen and I've had it happen on my pillar drill.

Steve

Hi Hood,
This is the spindle who start on its own and it is a relay who switch it on. Everything works fine except that scary thing
Here is the XML you requested enclosed.
Thank you so much.

Bruno, I´ve been watching the instructions videos of Mach3 maybe 10 times because I´m trying to setup my machine, and the man talks about your problem and how to set it up, in one of the first videos. Nr2 or 3 i think.

Bruno,
 how do you normally start the spindle, is it  just with the screen button? I dont see anything wrong with your xml so I am wondering if there is a possibilty of your keyboard being noisy, is it a wireless keyboard? Have you tried a different keyboard.

All I can think of is to make sure you have no noise issues, make sure you are using screened cable to feed the relays coil and only have it grounded at 1 end.
