Question about ABL and BLTouch.

Question about ABL and BLTouch. I use hair spray on my bed and something I am wondering is how can ABL work with that? I would think that the ABL would just sit on top and the spray may be low in spots and adjust down to that level so simply doing a Z compensation would be a very bad thing as it would scrap into the glass in spot and in others would be what I need. How do people work with this since we want the print to go into the spray but not through the glass? https://reprap.org/forum/read.php?1,858036,858036#msg-858036 Sun, 09 Aug 2026 16:09:55 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?1,858036,858051#msg-858051 Re: Question about ABL and BLTouch. https://reprap.org/forum/read.php?1,858036,858051#msg-858051

Use a ABL method than can save the results to eeprom, and only probe when the bed it clean every now and again.

your argument is flawed

you probe it hits glass, takes a measurement, next probe hits spray, takes a measurement.. The average of these is always higher than the glass!

Good to know but the bed changes so is best to do each time. Average could be anywhere since the pray is never going to be dead flat.
