I will do that! Thank you!

Thank you very much bearer! We measured the resistance of both components

I purchased the board via filafarm on November 2nd, would this be applicable for replacement under warranty?

Yes, we would see a short-to-ground error in the web interface after the driver failed

Dear Duet3D Team,
we recently bought a Duet 2 WiFi and connected it to our Ender 3 V2 in order to upgrade it to dual extrusion. Everything worked fine except the stepper motor driver E1 which blew up immediately after addressing it (see picture below).

The second stepper motor we used is the same type as the one that came with the Ender. We checked both stepper motor and wires after the incident and couldn't detect an issue.
We used the RepRap Firmware Configuration Tool to update the config.g file for two extruders as shown below.

We are unable to detect the fault ourselves and are hoping to get some insights here.
Thanks in advance!
