M03 and M8 Reset?
« on: September 21, 2012, 06:51:41 PM »
Hi,
i'm waiting the maker of the machine i use to help me out with this, but maybe some of you can help out.
This is, as an example, the beginning of one of the programs i'm using:

G00 G49 G40.1 G17 G80 G50 G90
G21
(2 1/2 Axis Pocketing)
M03
M8

I'm using Mach3, of course.
Either at M03 or M8, many times but not always, the program stops, i hear a 'click' in the controller box, the reset button flashes and i get the message "External EStop Requested".
If i rewind the program, reset and try again, eventually i get it to start both the motor (M03) and the vacuum cleaner (M8) and the program always runs smoothly from there on.
I suspect it has something to do with the two AC out in the controller, but have no clue about what to do...

Can this behaviour have something to do with Mach3?
Thanks for all the suggestions,
D.

The click is the relay for the coolant or/and spindle switching on and the reset is happening because it is producing noisewhich Mach is seeing on the E-Stop input. If you use the parallel port then try setting 2000 in the Debounce Interval setting on General Config page. If using an external device then it will need to be addresses in it.

Hi Hood,
i'm using a smoothstepper, so if i have this correctly, i should change the values in the smoothstepper's config dialog, under 'noise filtering'.
And if that's right, will i have to change the value only for the Estop input?
If so, what kind of values should it try?
Thanks a lot for the help,
D.

Yes that is correct on both, try 1.43 for E-Stop if not then increase a wee bit at a time. The steps are 1.43 but you dont have to be exact with them as it will just default to the lower. What I mean is if you entered 3 the filtering would be seen as 1.43 by the SS.
Dont go too high though as you may end up with a delay if you need to use the E-Stop, personally I wouldnt like to go much above 10.

Hood,
that seems to be working; just 1.43 and i did not get a single reset yet.
Thanks a lot for the tip.
Best,
D.

Yes I had a problem on the very first machine I put the USB SS on with the spindle occasionally tripping the E-Stop, 1.43 on it also cured it for me.
