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?

[zhangxueyou]

There is a fuse for ramps1.4. What is your board type?

[darxide]

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

[zhangxueyou]

From your solution, we can conclude that something wrong with PS. Did you connect the PS correctly before?

[darxide]

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
