Checked that , is there something on the motor itself that could cause this. The board has been installed for a couple of weeks now. This is the second time this has happened to me with 2 different duets. I see at least one other thread on the same topic.

Ok – so the same issues happened again. the z-motors are messed up after a print (4 hours ) and one of the motors has a burnt pin. ( this is with the same motors but a different duet wifi). I am beginning to believe its me and not the duet. I had not touched anything on the duet and it has been printing fine for a couple of weeks. I guess it could have been a bad crimp but I don't really believe it. What else could cause the over current?

I will re-crimp the wires and see if the driver is ok.

Ok thanks I will recheck everything again tonight.

I verified that the motors work by using the x and y connectors.

No burn marks on the underside or around the stepper. I rewired it but now its not driving the motor at all. ( I also checked the motors on the other x and Y ) It has been working fine for about a month. Any other Ideas?

Thanks
Eric

You can see the burn mark here the crimps on the end looked good.

Do you think If re-crimp the ends it will be ok?

My Z motors are having some kind of issue. I left a print running last night and this morning the z axis would only run in one direction. I have 2 z motors and one of the z motors cables has a burned spot on the connector for the red and blue pin where it connects to the board (z1). Both z1 and z2 are having the same issue.

Previously I have had a issue with the fan VIN not working correctly I switched it to the 5 volt and it has bee working fine. I purchased the unit in January and have not had any other issues with it.

Any guidance ?

Hello,

I have a question about the 7 inch Panel. I see reference here:

https://miscsolutions.wordpress.com/paneldue/

that I need to solder the 3.3v jumper on companion board if you have the 7 inch Panel. I just purchased the panel and the companion board from https://www.filastruder.com and I did non see mention of it there or on the base wiki.

Is this correct?

Thanks
Eric Smith
