General Mach Discussion / Re: setup problem with inputs not communicating from a C-10 breakout board

OK - that would be active lo instead of high.
I'll try it tonight.
Thanks

Sorry for the delay. I had partial success.The jumper on the C-10 is set to Pull Down (1&2)
The input signals are set in Mach at
X (all three)   Port1 Pin 12 Active Lo
Y         "         "           13      "       "
Z   home only "           15      "       "
A  (all three)   "          11      "        "      (slaved to x)
E-Stop            "          10      "        "
+5v is jumped to each pin
 I'm jumping at the board to eliminate any error in connection through the switches themselves. The diagnostic screen is clear with all pins connected to 5v.
When I disconnect 5v from pin 10 I get an Estop led as expected.
When  I disconnect pin 15 from 5v I get a yellow home on m3 which is as expected.
I get no response in disconnecting power from 12, 13, 11. I have verified the 5vdc signal on all pins.
I can imagine a physical connection issue on the cable or socket or possibly a bad chip.
I'd appreciate any ideas you have.
Thanks,
Guy

Thanks very much for responding. The Mach manual prefers active lo. I assumed that to send active lo I would use the +5 and the pin for the circuit. I also assumed I would want use the pull down jumper. I understand how to toggle the active hi/lo on the mach config screen.

Are my assumptions - +5 and pin  and set jumper to pull down correct?

Many thanks for your time on this.

General Mach Discussion / setup problem with inputs not communicating from a C-10 breakout board

The good news is all the outputs are fine and all axis drive motors. Trial cuts were successful. The problem is getting the input signals set up for limits. e-stop , and home. I assigned the pins and set the port in config. I get no response on the diagnostic screen when jumping/unjumping the pin and 5vdc . I toggled active hi/lo with no response.

The board is set up for both inputs and outputs.  There are 5 unused. 10, 11,12,13,15 none respond on the diagnostics screen.

I tried setting up my backup breakout board - same thing - so it must be the setup ?
Any ideas I can try would be appreciated.

I found it - it was a Windows problem - under control panel - display i reset the font sizes to normal and everything went back to normal - duh
sorry to bother you - I kind of suspected it would be stupid

I can't see or click on the OK. button in the lower right of the General Logic configuration screen. Auto screen enlarge is active now as well as boxed dro's and flash errors.HiRes is not enabled If i change a selection it isn't saved without clicking ok. I did restart and the same problem persists. I also can't see the right side or bottom of the 1024 screen set screens.
thanks

My most common (and expensive ) error is forgetting to reset the Z axis to zero after a tool change. I've forced myself to double check it every time before i run a part program. I shouldn't admit - but I will - that after an accidental e-stop loses my home position i sometimes just manually jog to where  zero on the part should be, reset the dros to 0 and run.
