Hi, I'm building my first printer and I'm having trouble configuring the firmware. For the printer geometry section, should I put the distance from the endstop to the corner of the bed for the minimum boxes?

I asked on Reddit as well and I got answers that it's just the ground for the wifi module. False alarm

I just received my duet wifi and there is a copper wire soldered on the end of the wifi module going to the SD card slot. Is that supposed to be there?
