I found a couple broken wires going to the motor but I still can't get it to work. Now I can't even connect to the board. The light by the wifi antenna is not one and I can't get a COM port by plugging in the USB cable. The only wires that are on are the LED +5v and LED VIN.

I'm getting the same error now all of a sudden. My machine has been wired for several months. I've recently been getting anomalies in my prints, looks like not extruding enough on the border, could be layer height and have been trouble shooting. I swapped out the nozzle. Now I get this phase message when I try to home my Z axis. Here is my config.

Any ideas?

I don't know if they are brushless or not. They are 30mm 12v fans. Most of which I got from the filastruder company so I would think they would be compatible. I don't see anything on the 3pin mosfets. I think those are the little chips just above the outputs that have 2 little pins on one side and 1 pin on the other. Nothing looks charred or anything.

It doesn't look like my config file got posted. Here it is again.
config.txt

I recently purchased the Duex 2 and Duex 5 Expansion Board - Duex2 board for the Duet3d wifi. I now have 3 of the fan ports that have stopped working. Yesterday, I was watching one of the temperature activated ones and it just stopped and I can't get that port to work again. Ports 3, 5 and 6 are the ones I can't get to work. All 4 of my fans function when I have them hooked up to functioning ports. So the wiring for the fans should be good. I've changed my config.g file to point to the working ports up until number 5 quit. It's still in the config but I can't get the fan to work. It should start with the M106 command but it doesn't.

Here is a pic of my board.

here is my config file.

I have the mini differential IR Height sensor. I'll try removing those files and see what happens. I checked and they are there.

Ok, I see what you are getting at but I have my X- off the bed and I make sure my print doesn't try to extrude in the air.

So, that being said. Why does the head try to move past the end stop?

I don't understand what you are saying. Tool 0 is my left nozzle, but when it's homes, it would be at 0. Why do you say it would be at some negative value of 0? My right nozzle, Tool 1 would then be at 33 when the head is homed.

I reset my G31 to X0.0. I had been trying to see if it had something to do with the dual extruder. It still tries to go past my end stop. The sensor is over Tool 0 so when the head is homed, the sensor should be at 0 also.

When I use the G29 command to probe my bed, I get some strange behavior on my X axis. I think it may have something to so with my the way I have my X axis set up. It is a dual head printer so when X is homed, the left nozzle is not over the board. I have tried to configure that in the config.g file but I may not have it right.

When the probing starts, the head moves up to Z40 and X35. Then the X moves toward the endstop and tried to move past it. It then probes the bed but I don't think the X readings in Web Control are accurate. I had to reduce the right parameter for probing so the head didn't move past the end of the bed on that side.

When it's done probing, it tries to move past my X endstop again.

I do get a map, I haven not tried to print with it yet so I don't know how coordinated will line up.

I'm running with firmware 1.20. Here is my config.g file.
