I just noticed this article, dated 20 Jan. 2021, 9 days ago as of this writing. This may be exactly what I need.
I think that may be a repost or something because ive definatley seen that
maybe they changed some wording or something.
Well, I’d not seen it before, so it’s al new to me.

Finally had some time to do this.
But I added another step and put the nozzle into the correct position, touching the nozzle to the sticker. Then I added cards and gauges until I could measure the actual gap.
What should have been 1mm was actually 3mm. That could explain a few things.
Then I went through the steps to adjust it to exactly 1mm. I’ll let you know how it works now.
I’ll also mention - credit cards come in different thicknesses. Some are less than .5mm
Use your digital caliper (What? You don’t have one??) and check the thickness of your cards. I finally found a credit card that is .85mm and together with one of the Snapmaker rulers, got exactly 1mm.
And THAT’s what I used to adjust the height of the sensor.
nice. i dont think it requires extreme precision, as long as it isnt too far away though.
The last step with the calibration card is what tells the SM the difference between the height being sensed and the actual nozzle height. It just needs to be close and better to err on the side of too close than too far.

My suspicion is that the further away the probe/light is away from the plate, the more variability/lesser accuracy in the measurements.
