General Mach Discussion / LED question

« on: April 02, 2010, 06:10:12 AM »

How do you get the X zero, Y zero, and Z zero LEDs to change from green to red after you hit an E-Stop? (this would indicate that you should do a "home ref." before continuing) My system used to do this and now for some reason it is not!

Logical conclusion! I will look into that. Thanks.

Hood:
I have finally located the source of the "noise" that was triggering my "reset" button, however the answer needs an explanation! I have all my limit switch (shielded) cables grounded on the limit switch end only. When I remove the ground wire, everything works normally with no triggering of the "reset" button. This is just the opposite of what you would expect. I have tested this both ways over an 8 hour period and feel confident that this was the problem. Any thoughts?

To be honest with you it was so long ago I don't remember! I will do some research and if I can find my old notes I will get back to you.

Thanks Hood. I have located a faulty 25 cond. ribbon cable inside my control enclosure as the cause of the latest problem. Now that I have fixed that, I can get back to solving the previous problem.

Only the X axis jogs with either the MPG, Tab page, or keyboard. The DROs do indicate movement on all 3 axis.

Changing this has no effect on the problem! The X axis still works fine with the MPG. It sounds like you are running out of suggestions! I do greatly appreciate all your help on this. Thank you. I will keep plugging away.
Regards,
Charlie

Hood:
Not sure you got my last post?   I now have a different problem. Neither my Y or Z axis moves either using the MPG or trying to do a homing move. The DRO's do index. I haven't changed any settings, however I can't continue to troubleshoot my previous problem until I solve this one. I have attached the most current XML file.
Thanks,
Charlie

When I enable The X--, Y++, and Z++ limits, along with the "home" LEDs, both the "home" and "limit" LEDs do light up on the diagnostics page. That is when the problem of the RESET button starts flashing! It happens randomly and I also noticed that the limit and homing LEDs flash quickly just before the RESET flashes. It is almost like enabeling the limits is causing the "noise" that trips the RESET. This dosen't make sense because the wiring and switches are all the same and the RESET dosen't trip when only the home switches are enabled.

I have one switch on the end of each axis which is enabled as a homing switch. They are each wired in to individual inputs on my breakout board. When I enable them as limits, that's when I have the problem. I also am having difficulty setting up the soft limits.
