Hey folks, I recently finished my Lowriderv4 with the Jackpot and it’s been working like a charm without issue. Today when I went to home my machine the y1 endstop never triggered. I validated all my connections. I also validated that my connection to my motherboard worked by putting my y1 header o…

Wanted to follow up on this because I had my final expendable pin go into this state where it is stuck in a triggered state with the light on. Is this a full board replacement, or can I just swap out the ESP with a new one? Thanks!

Your pins should not go bad. What endstops do you have plugged in? Any chance of static issues? I have replacement components that I can solder on, but this is odd. The first board to have pins go bad after the fact.

I have every endstop with the exception of X attached. I won’t say there is 0 chance of static issues, (since ESD ghosts and all), but I have grounded my entire setup. Since this appears to be unique to me there must be something about my interaction with the board causing this. Might just buy an ES…

Let’s see a picture of your board wired up. Do you have your Vac hose grounded? If you want to send your board in I can replace the endstop components to fix it pretty easy.

Here are a few pics. Yes, I have my vac hose grounded as well as my fan. What does that repair process look like? Is it something I can do at home? If not, I am down to send it in! [IMG_0168] [IMG_0169] [IMG_0171]

I do not! That is the ground wire from my vacuum. I attached it to the metal rib to the ground port on the board.

do you have a reference you can point me to for conducting the repair? The guns don’t seem to be that expensive and I’m all for trying something new and acquiring a new skill

Here is the component that gets swapped out. [PXL_20251027_202110435]

Well, that would make sense. my intentions were good :joy:
