        What is the fan voltage?

        If the fan was 12v and you had the fan jumper to 5v, the fan would be spinning slow because it's not getting 12v.

        If the fan is 12v and you set the jumper to vin and you psu is 24v the fan now has twice as much juice flowing through it which is sure to cause damage.

        To use a 12v fan with 24v vin you would need a buck converter to drop the 24v down to 12v for the fans.

        Can you post a photo of your board to see what might have been damaged?

          @Phaedrux I switched it all upto a previous version of my duet wifi which has no car fuse etc, the fan hasn't changed but you could tell that their was an issue with the 1st board to begin with... Everything on the older board works including the y axis. So who knows I may upgrade to the duet wifi with 3 fuses if all goes well and continue testing on this board

            Is there an option to send this board back to the team for a review and fix or atleast how would I go about doing the trace pcb checks

                It sounds like it's gone poof. If we could see if there is damage, and you can explain what does and does not work it might be viable for repair.

                  The 5v rail has gone since the WiFi doesn't switch on, the 24v power delivery doesn't work it's mostly the power delivery system, with issues on the y axis stepper driver nothing appears burnt other than the bltouch which ended with a slight spark and and is now burnt....

                  The fan works normally as when plugged that in to the previous release of the duet it worked as expected, I'm not going to use the burnt bltouch and have ordered a new one

                    Can't rate it enough how refreshing the duet wifi is, and for quality of life stuff its worth the cash, working with marlin was great but really everyone I go to the duet wifi difference is shocking, when I plugged my mp mini select 200 that printer was completely silent

                      Is there are sign of damage to the small square chip U3, which is close to the VFAN select jumper?
