The current probe does not detect glass just metal. The auto leveling is fine just the the detection that doesnt work. Some people use a FiFix and this does work but I wanted a more permanent solution so I replaced the existing induction sensor with an Infrared one.
I wanted an alternative sensor that would work on glass and if possible would fit within the main body of the print head. After some research I found an IR sensor that gets good reviews for accuracy and is small. It is 3.3V or 5V and logic high when triggering so I knew there would be some wiring issues but it’s small enough to fit on the right of the nozzle replacing the existing sensor and the right side fan duct. I think the right side fan duct doesn’t work well ( its removed in the new he…
Eventually wrote up what I did.
I have written up the process I followed to replace the existing proximity sensor with an Infrared sensor so that the print head will level on glass. I have included a wiring diagram for the new cable thats required and STL’s for the two new parts that need to be printed plus a load of pictures that should make the process more obvious for anybody else that might want to give this a try.
Happy to take any comments or clarify anything thats not clear. If somebody does look at this and sanity c…
