How does BLTouch auto level work?
The key difference between an inductive probe and the BLTouch is that the BLTouch sensor physically touches the bed in the leveling process. The inductive probe uses currents induced by magnetic fields to detect metal objects nearby, eliminating the need to physically touch the bed in order to sense it.
Should I manually level my bed with BLTouch?
Level manually before every print: Even though you now have an auto bed leveling sensor, it still helps to get at least a somewhat level print bed before each print manually. Then, the BLTouch leveling sequence will fine tune it to perfect flatness.
Is a BLTouch worth it?
First of all, BLtouch is not necessary as long as you use a flatbed. So if you have any problems with the leveling, BLtouch is absolutely worth it, especially if your bed is not conducive. If you want to choose bed leveling for your printer, BLtouch is the best option among different models.
Does G29 turn on bed leveling?
After a G29 bed leveling is automatically enabled, but in all other situations you must use M420 S1 to enable bed leveling. It is essential to include the command M420 S1 in the “Start G-code” in your slicer settings. If you have no bed leveling, or if there is no leveling data, then this command is simply ignored.
How do I know if my BLTouch is working?
In the LCD menu for BLTouch; select CMD:Self Test : BLTouch turns red, extends and retracts several times. In the LCD menu for BLTouch; select CMD:Extend : BLTouch extends. In the LCD menu for BLTouch; select CMD:Retract : BLTouch retracts.
How to speed up the bltouch auto bed leveling?
In Marlin firmware, the speed setting in between probes is found in Configuration.h: // X and Y axis travel speed (mm/min) between probes #define XY_PROBE_SPEED 8000 In TH3D firmware In TH3D firmware this speed is buried in the Configuration_backend.h:
How to speed up th3d auto bed leveling?
G-code G29 has a speed parameter: From below (TH3D firmware) can be seen that a value of 12000 mm/min will speed up and is generally safe to use. In Marlin firmware, the speed setting in between probes is found in Configuration.h: In TH3D firmware this speed is buried in the Configuration_backend.h:
How to set up Marlin for auto bed leveling?

How does a three point bed leveling work?
Three-Point: Probe the bed at 3 arbitrary points and apply a matrix to the bed’s overall tilt. Planar Grid: Probe the bed in a grid and (like three-point) apply a matrix to the bed’s overall tilt.
