So I have a Wanhao Duplicator I3 V2 that I came back to after I broke a few parts trying to clean it, and one of the main issues it now (it worked fine earlier) has is that the X limit switch has a delayed activation. You press it, and then 1 second later, the printer registers it. I have ruled out the switch, it's fine. Most of the info I have to go on is that it seems like it could be a broken/fried pullup/down resistor.
Is there some good way to fix this? Thanks!
