Oh, thank you, that's what I will do

Hello Duet 3D team !

First of all, I would like to thank you for your (huge !) contribution to the world of reprap.

It was suggested to contact you on the duet3D page for technical informations.

I've bought a mini IR differential sensor board from duet3d on the 16/11/2017. I've been using it with pleasing results since then. I plan to switch to the smart effector that I also bought, and to use the mini IR differential sensor board in another printer. It seems to have a very strange bug. The board now triggers 40mm above bed, very unreliably, and then, have a second good triger about 1/2mm above bed.

I made a video of the problem https://www.youtube.com/watch?v=4zzD7JafLWY

I previously contacted David on the reprap forum and told me I should ask for a replacement...

I'm not sure the forum is the best way to do this, but it was suggested on your website to use the forum rather than email...

Anyway, I love your products

Clément
