Mach3 OEM codes for Feedhold and CYcle start

[mrpeja]

Hi,
I just configured two switches connected to two parport pins as OEM trigger, one with OEM code 1001 for Hold and another with OEM code 1000 for Cycle start. No mather what Mach3 screen is active, I allways get (almost) blank screen when I press any of two switches. Bar on the top and Reset button are visible. I think that shouldn't happen. HELP!
BTW, isn't Resume  (code 1005) better than Cycle start for continuing?

Please attach your xml.

Hi Hood,
I tried this without any job loaded, just for testing switches.
There is xml

[Hood]

you have -1000 and -1005 in the Oem Triggers, you should not have the negative there.

You also have the E-Stop on the same pin as the Limits, is that the way you are meaning to wire things up?

THANKS A LOT! , Hood
Now I get "Nothing to FeedHold".That's OK.
BTW, why is -1 as defult value in all OEM fields?

[Hood]

Feedhold is 1001, the OEMs you have entered are 1000 and 1005.
Afraid I dont know, presume its just a default for Mach to ignore.

Hood,
I used such a schematic and this wiring from Mach3 manual. Estop and Limits activation will disconnect power for stepper drivers and stops job execution.
Also I have separate set of home switches wired to another pin. Do you think there is a better solution for plasma table?
Please advise.

Normally you will have the limits wired in as you have them,  then an E-Stop button wired to a different input.
 The reason I do it that way is my E-Stops are all Double contacts, one side is the 5v for the breakout and Mach and the other  is the E-Stop string that cuts power to all contactors in my machine. That way if a limit is hit the drives power is still kept to drives etc , just Mach stops motion, if the E-Stop is hit then Mach stops motion and also the AC to my drives and other motors are cut.

Yes, Hood,
Your solution is better than mine.
I'll change mine tomorrow.  Also I'll check my OEM codes (1000 and 1005).
Once again, isn't Resume (code 1005) instead of Cycle start more logical?
