My father and I recently just built a RoStock Max V3 printer from SeeMeCNC. We finished it and were very excited to power it up and get it going. We checked the connections and plugged it in, and the controller didn't turn on. I watched a video suggesting that a 5 amp ceramic fuse had been shorted, so we ordered some more and replaced them. Still nothing. The extruder lights are on, the motherboard is showing a red and green light, all the fans turn on, power supply light is on. It seems that everything EXCEPT the controller is working. Can someone help me out with this?

what version... in particular what controller do you have?


Duet?



or RAMBo?


If Duet you do have the sd card in the sd card slot? as it needs that to work.

I have the RAMBo board.

I just remembered that we got it fixed. Thank you for your help.
I fixed it by changing the orientation of the connectors of the controller to the board. The pink stripe needs to be on the left when facing the board.
