In addition to the question How can a force sensor automatically determine the Z-offset?.

Is there any well-documented 'auto z-offset' (DIY) upgrade available for 3D printers? I'm particularly interested in using a strain gauge and upgrading the Creality Ender 3 V2. But examples for adding this capability, using other methods or to other printers are also welcome because I can modify it.

  • Is there a rationalle behind the request, e.g. usually you do this once. E.g. I even don't ABL my printer for every print, just using the stored leveling surface. Does this relate to earlier questions regarding the frequent change of nozzles? Note that the option you are describing is a Creality development which they do not share with the rest of the world. – 0scar Dec 01 '23 at 13:47
  • Good question. The reason is that I sometimes switch nozzles with limited effect but also beds with either a thin magnetic PEI or thicker carborundum glass. It's not a big deal, but I like tinkering and automatic things. It's just a quality-of-life improvement. They don't share, but the concept seems essentially simple enough to implement, although I don't exactly understand it well enough yet to implement it. – Bob Ortiz Dec 01 '23 at 17:23
  • If you change the setup frequently that might be very handy. Maybe you could add that to the question. – 0scar Dec 01 '23 at 20:12
