General Mach Discussion / Re: Moving off Limit switch
« on: June 14, 2009, 07:21:32 PM »
I ran new shielded wires and the problem went away.  The old wiring was twisted pairs without shielding!!!.

on the suggestion to increase the voltage to 12V or 24V I am afraid that  will likely burn the TTL inputs of the card.

I still get an estop spurious trigger. Is the estop switch also debounced in Mach?

the wires are shielded but are not configured as  twisted pairs. Three pairs of wires carry all 6 limits switches inputs with one common 5 volt  wire going to all swithes.
I never thought that steady signals can such a source of noise frustration.

You were right. I have a very noisy input and after I reset something triggers it again.

thats why I could not  see the reset taking hold!

I use a a parallel port breakout board (C-10 from CNC4PC).  I have set it active low. when the switch the 5v input is cutoff and  the input is hanging unconnected.  I suppose it picks  up the occasional noise that trigers  it.

my challenge is to get the input to  stay  low,  when I cut off the 5v signal to it.

Just to make things clear. the RESET button is the big GUI button on the Mach screen. I dont have a physical reset button. did I get this right?
I do have a debounce of 400 on all my inputs so it is not a debounce problem.

thanks for checking the xml  me. I tried with the standard screen with no success.
The reset button does not clear after I pressed it and the alarm state remains. I cannot walk away from the switch unless I disable the switch from the inputs configuration.
It is so frustrating not to be able to duplicate what everyone else is getting.

I have turned on autooveride. I hit the limit switch and the system  goes on emergency stop. I hit reset but emergency mode keeps flashing and I cannot jog away from the switch. what am i missing. ????
the only way to move away from the switch is to disable it...

Yes I did check on the wiki but found no reference to the mach functions that the wizzard does not cover.

General Mach Discussion / Mach 3 help wizzard

I wonder why the Mach 3 Help wizzard has not been upgraded over the past two years. there are  dozens of buttons where the wizzard pops up to just say "sorry no help for this function...."
is there any reference documents that enumerates the Mach 3 functions or buttons?

Thanks

I need some help understanding the difference between the  two forums: this one and the yahoo mach support group.

I started experiencing problems with the yahoo support group.
my postings do not show up and the search function seem to screen out the messages from the last year.
Does anyone know if the search function of the yahoo group is working properly?

some clarification on what is where will be immensely helpful.
thanks
John
