Is my Trigroilla Board fried?
Hey guys,
I´ve spent days now trying to figure out why my Bltouch on my Anycubic i3 mega suddenly had issues of only working sometimes and now not working at all as it keeps interrupting the X Endstop.
Previously I´ve "installed" the UART Mode but it looks like sth. bad happened when I resoldered the Bltouch to the subboard or when i soldered the pins for the UART Mode (Im not new to soldering, but when i did all that i rushed it and wasnt double checking so i might have bridged sth. by accident)
Ive come as far as to find out that my X_Min and X_MAX seem to be bridged, which shouldn´t be the case imho, but im not 100% sure as Pin D2 and D3 are both configured as pullups.
Im super confused and even ordered a new Bltouch thinking that one was broken, reflashed the firmware with KIUAH (im on Klipper) but now im afraid i somehow accidently fried my board.
Would someone be able to let me know if X_MIN and X_MAX are bridged by design in anyway?
(I also followed the board lanes and sadly noticed the bridge on the 2 pins on the atmega chip as well)
I´ve cleaned everything and dont see any obvious damages on the board so im a little lost.
Maybe I dont see the easy solution anymore, so any other help is greatly appreciated to avoid buying a new board.
Thanks in advance.
