Yes ive tried the x on both high and low and get no response from switch when I run m119

Have been trying to get endstops working. I have both z and y is order but I cant get y to operate tried switching wires switchs and strait up unplugging it.... could the onboard resistor b dead?

Yes all was working fine. I was working on calabrating The motor hit the endstop and it didnt trigger then pop and the 12v was gone

I have ramps 1.4 but I plugged in a new 12v ps and it is working.....

i recieved my prusa i3 pro b. built the kit and was in process of calabration when the y access motor bound up making a pop sound and power supply stopped working. is there a fuse on the psu? or is the supply burnt?
