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 check it I will post on the Facebook site.
