Diagnostic Screen Confusion
« on: January 12, 2014, 12:56:05 PM »
I try to solve why my limits do not work properly and I would like to know what the lights on the diagnostic screen mean.

All my limits except the home switches are connected to one pin. When I push any limit the following lights come ON on the diagnostic screen
Under EjogY+ M1 and M3
Under EjogZ+ M1,M2,M3
To me the EjogY+ should not light up because I don’t push any limit on the Y axis but perhaps it is not important and that is what I would like to know

When I push the Y Home, the following lights cone ON on the diagnostic screen
Under EjogY, M2
Under EjogA, M2

When I push the A Home, the following lights cone ON on the diagnostic screen
Under EjogY, M4

Do the above indicate a problem with my wiring?

You have something screwed up, if  you have all limits in series then pressing 1 should light all the limit switch LEDs, ie M1, M2, M3 and M4 ++Limit and -- Limit. Your Homes should only light up the home LEDs.

You must have the external jogs in ports and pins set to the same ones as you have the limits/homes set to.

Your are right Hood I got something screwed up but I have checked everything I can and I can't see anything wrong. Limits wiring is simple, they all are in series and go to one pin with shielded cable. Home Y & A also simple one shielded cable each going to a different pin. All cable shield grounds are attached at the panel end to earth ground

I have attached my XML, can you please have a look to see if you can spot an error?

I also attach my schematic for the limits

Thank you
Nicolas

xml looks ok
What does the frequency on diagnostics say?
Might be worthwhile setting up a new xml.

The frequency on the diagnostic screen is 25250 and it varies +/- about 100. I will delete the XML and re configure

Thank you

Sorry Hood but I'm going from bad to worst, lol. Deleted the XML, re installed Mach3 and re configure all parameters as before including the motors / tuning etc. axes are enabled but now the motors do not move kith the keyboard arrows (DRO's are moving) but I hear that I do have power to the motors when I turn the power to the drives.

E-Stop and Limits are working (when I push them manually) unfortunately same as before, frequency on diagnostic screen is again about 25K, and have no lights ON in the diagnostic screen. Power light on the BOB is ON

What did I forget?

My new XML is attached

The cable shields are touching each other inside my control panel and eventually they end to earth ground. Does it matter that they are touching each other?
