What am i looking for, If you can point me in the right direction in plain English i can tell you.
Normally once it is close to the bed it simply turns on and that is it. Instead of Using the X stop switch you use this to home your printer. How ever the signal is very weak and your Led on your board (duet Wifi) only just flickers. So its ineffective.
Power to it is proved by a 5v USB line. As per on there site.
I have noticed you sell you own Led board and will look into that, seemingly every ware is out of stock of it. When will you be getting these back in ?
I don't think my Cr-10 can be called a CR-10 any more.
