Re: BLTouch Auto Leveling Sensor

have you guys noticed that if your bed is already pretty level, auto-bed leveling does nothing? I wanted to get my bed pretty level to start then have the BLTouch do the fine tuning, but it doesnt do the fine tuning. If you deliberately un-level your bed, do you see the Z-axis move when you print? ...

Re: BLTouch Auto Leveling Sensor

Z_HOME_BUMP_MM in Configuration_adv.h Marlin apparently uses the same value for all Z-axis moves, whether they're homing or bed probing. Oh man . . . thank you for this. I was having the same issue where the z-axis wouldn't retract all the way down before the second (slow) probe occurred. Everythin...

Re: BLTouch Auto Leveling Sensor

I finally got the BLTouch working. It was a bit of a learning curve for me, but now that I know what I'm doing, I could probably do it in an hour or so. The steps will vary somewhat depending on your particular M2 revision. Mine was purchased in 06/2015, and was upgraded to a V4 extruder. It has the...
