Help me I think my endstops stopped
-
@adalton5683 IO_1 and IO_0 are also similar and it looks like theyre on a different buss. I think im going to swap out the molexes for 5 pin ones and move them over there. that should tell me if 5 and 6 are blown. from the docs they only can take 30V. I def didnt put more than on them or whatever that goes to them so idk how that happened if so.
ill check back in 15 with if I caught the board on fire yet or not.

@adalton5683 So.... I noticed also that my Zhigh endstop isnt working either. idk wth is going on.
I swapped over to IO_0 and IO_1 for the endstops and reconnected and they are still no go. I ran back through the config.json and reassigned them and rebooted.
nada
any help would be amazing. I cant really wrap my head around the idea that 2 seperate busses (or at least I think it is) IO_5/6 and IO_0/1/2 are both toast. Buuu my BL touch on IO_4 is still happily working.
are any of you guys people that know the actual circuit diagram like how th eauxiliares are routed, protected etc. like say it overloaded does that go back to the fuze or just poof?
do I have options to hook up to if I smoked the IO bus? aaaaand well I already bought another board im just really sad about it I really expected more out of the resillency of this board from all the hype on them and I cant even get it to a first print. And im an electrical engineer(who sucks at circuits) but still this shouldnt be this hard. or fail electrically out of nowhere.

So ......
I had that Z highend endstop wired up right and was checking it. well I think it may have been wire wrong and it was taking that entire bus to ground. only with the 3.3 v so no harm no foul and thus I swapped the wire and now im working on all endstops.
god I hate circuit analysis. Give me PLCs and controls all day over this. haha I wanna design and pay people to put it together.
BUT... now to the reason I actually started this thread. (no it wasnt the endstops that happened right when I was posting so I edited.
My issue: My bed is all outta wack like orient-wise. Ive went through how to get a mesh bed to work and it always fails or doesnt generate a mesh.
Here is my coordinates when my nozzle is perfectly over the bottom left of my bed and
ignore z height its perfect with however I set up my probe offset.(2.5 I think)
But when I go to the opposite end of the bed MAX(X,Y,Z) I get only to
heres my config.g

Where is the nozzle when the endstops are actually hit?
If the nozzle is off the bed edge then you can set the axis minimum to a negative value such that 0,0 is right at the corner of the bed.
But I don't understand how you have negative values at the bottom left corner if your endstops are at min and set the axis to 0.
