i'm so confused. I do G28 to home. Then I do a paper test and get a z-offset of say -2.4. So I run M851 Z-2.4 To set the offset. Then I run G29 To run the ABL routine, which gives the printer a grid to adjust to. Now I start my print job and it is printing in the air. How much in the air? I'm guessing 2.4mm. OK, so the offset should have been zero? So I do M851 Z0and run the job agaiby bcsteeve - Firmware - Marlin

Are capacitive proximetry sensors accurate enough with glass ? Is it possible the capacitive sensor is actually getting reflections off your alluminium bed. Sure they are. Inductive wouldn't be (well, it would be, it wby bcsteeve - Firmware - Marlin
QuoteRoxy You may be running into this issue: The reason for the flaw is not currently known. You might want to switch to a different bed leveling system until this is fixed. Yeah, that sounds like what I'm experiencing. FYI Linear and Bilinear both have the "effect". I haven't tried 3 point and my system (CR-10) can't handle UBL. At least not without some serious feature trimming (I trby bcsteeve - Firmware - Marlin

I'm having a frustrating experience. First off, things have gone well for a long time. But I changed my print surface so I had to run the ABL routine again. I have it set to Bilinear. My bed is pretty flat as it is, but I have it ABL anyway. Now with my new print surface, I'm less level (go figure), but I figure ABL will correct. However, when I print... the left side is tight and the rightby bcsteeve - Firmware - Marlin
