...I checked the bed level, and one corner (X200,Y200) is low by more than one mm. I'd like to correct this, only I don't know how I can set correctly this particular angle as there is only one screw in the middle of the Y axis and the other angle is set OK... Does this means the bed is bent? What can I do about it?..

If your smooth rods is twisted you will always end up with one corner low or high (if your glass is perfectly flat that is) - the fix is to adjust your acrylic end parts, here's an old posting about it
While we wait on (for) a functional auto-probing...:

Ho, sorry Dave I hadn't seen your answer.
And reading it I realize I hadn't the right rod in mind as I was talking about the Z axis
I have replaced the X axis arm by an aluminum version and I suppose it would be a good idea to have the end plates as well. But honnestly I don't know how to find these (for the arm I ordered it from this forum actually).

Erik, what problems are you having with the auto bed compensation? The 4-level probing scheme can compensate for twist in the rods (and it does on my Ormerod)Quote

- although it is better to eliminate the twist as much as you can.

To get accurate readings for bed levelling the sensitivity to ambient light is not too important because that should remain constant between readings and you are only looking for the differences in heights, not the absolute heights. However significant differences in the texture or colour of the bed at the various probe points will affect the accuracy no matter what sensor you use.

I have the Ormerod 2 4-wire sensor.
Just the other night I didn't think about it and run a Z homing with my desk 20W hallogen light on. I really thought something was wrong with the printer for a few seconds.
The printer is on the side of my desk, a windows is just 50cm away so I wondered if sunlight (ambiant, not direct, but still could matter) could light some corners more than the others.
Anyway I'm just being curious, the bed is pretty much level now and the IR sensor seems relevant (and autolevelling doesn't seem that much important with the level I have right now).
Thanks
