The sensor works indeed better than the original sensor but only partly. It is nearly light independant. Really funny. I put a really bright light source under the sensor and it was still able to detect the height. I only had a difference of 10 digits with light on and off.

You can use both a Z switch and a proximity sensor if you want, just use M574 to enable or disable the switch. You could also set up macro files to change the Z probe trigger height to handle different bed surfaces. You may find the trigger height varies less if you put black paper under the glass, or paint the aluminium heat spreader black.

I put the paper down under the nozzle and moved it slowly down until I barely could pull out the paper.

I noticed the values, entered it and the skirt looked awful.

Besides that: We live in the 21st century so I demand from my printer to do this automatically.

Besides regarding my Ormerod 1 the bed leveling seems to change for some reasons but I do not exactly why. One possibility could be if you remove a part and it stucks somewhere and a screw is not 100% tight you may get twisted rods.

Besides the additional costs for a MK3 aluminium heated bed to a MK2B or MK2A is less than the cost for the glass if you would like to have a good glass (borosilicate).

Did you ever tried a FLIR?

I do not believe that the heat is spreaded exactly the same high all over the bed you will have hot spots or you need a damn good insulation which overtakes this job.

... The second problem is that the manufacturing process of this kind of glass does not guarantee that this glass is even. To be 100% sure you need borosilicate glass which starts at 6€ for our printer.

Unluckily a FSR is a little bit expensive.

That means the E0 is switched with GND instead of 3.3V like it is common using Atmel microchips?

Thanks for the answer. I wanted to be sure as I was not aware of it until then. I saw it of course but I did not noticed it. Normally you switch with the positive voltage except for the Atmel processors. But I like the idea. And I also fully support that normally the NC contact is used.

Hello Dave,
there is one simply reason for doing this for Atmel processors: They have an internal pullup resistor so if you use GND as switch contact you do not need an external pullup or pulldown resistor.
