Thank you for drawing these assembly shortcomings to our attention. Please advise the Duet serial number - sticker on MCU - so we can identify the board and raise these issues with the assemblers at once. We would then like to replace your board with a new one and return it to the factory as detailed evidence of unacceptable practices. Please email firstname.lastname@example.org so we can set this up.

RE: Duet WiFi with external antenna
This is possible - we can get a batch of Duets assembled at the factory with the ESP07S module instead of the ESP12S, so no reworking will be required and the full warranty will apply. Please email me at think3dprint3d (at) gmail (dot) com so that we can discuss quantities, timing, etc.
