X5 Mini maybe X stop blown

Smothieware on a X5 Mini

My X stop seems that it may be blown on board…

even with the home switch unplugged the x is being triggered I can’t get it to go low inverted the pin in the software no change,

Is there a way to check the board and maybe replace what could be blown?
if not I guess i’ll have to replace it…

every thing else seems to be working…

Thanks gary

Not really answering your question but…
You could change the pins in your config and use the other endstop input for X and see if it works. Use X-min if you’re currently using x_max and vise versa. If it works you wouldn’t have to buy a new board at least.

I tried that also. Thanks

I got it working seems like it was bad optic switch I tried two with the same results no x home
they both looked ok red power led lights up blue led lights when triggered but no x signal
so I tried a 3rd optic switch and now its working, go figure 2 bad switches…

Thanks gary
