Hi, the validation in this video is not 100% correct. You should zero encoders before going down from 1 mm to 0 mm and then check if the encoders stay at 0. The point here is to find out whether the platform is flat/not tilted and does not excert pressure on the glas by itself. The rest of the video is excellent
Yes, you are absolutely correct, looks like we did miss a step there. You should absolutely zero and check the encoders at 1 mm before moving the platform down to the basin glass and checking the encoders again. Thank you for letting us know!
