Can guys recomend a different firmware other than Marlin that incorporates auto bed leveling? My marlin auto bed leveling is so unpredictable. I’m using an inductive sensor. One print it’s perfect the next print I’m crashing into the print bed.
Could it be your sensor? I am using marlin 1.0.2 with a servo. And it is rock solid. The only time I have an issue is if I change something on the Z axis.
@Keith_Applegarth I guess it could be. I’ve purchased another sensor but have yet to test it out
However I can link my printer with repetier and get consistent readings time after time
Having a spare is always good. And double check your wiring. A dirty or intermittent connection can cause all sorts of squirrelly problems.
Also, where are you pulling marlin from. I think @Scott_Lahteine said that the newer version has some issues with it
My version of marlin is from 2014
I can check to see exactly what version it is when I get home
@Mark_Rehorst I have a prusa i3 and I agree with your point, however I would still like auto bed leveling to work correctly
One thing to watch out for is that if there’s any plastic on the tip of the nozzle it will hit the bed before the sensor triggers and it will just keep driving downwards. I always heat the hot end before the auto leveling so the plastic is soft and doesn’t push down the bed.
Another idea. Could it be my slicer causing the issue?
Possible, but not likely.

Are you sure it’s inductive? I was using a capacitive sensor for a while and it was much worse than the inductive one I’m using now.
This is the sensor im using
I made a discovery. i tried repetier firmware and didnt like it so i switched back to marlin a auto bed leveling worked perfect. Question: Does G29 store the bed measurements and try to reuse them? Is there a Gcode command do delete this stored info and start every print brand new just like i reflashed the firmware?
You add the offsets to the Marlin firmware in the configuration.h file. Then add the G28 and G29 to your start code. It then stores it just before the print.
Ok that’s what I do but after a few prints it starts getting squirrely. Is there a way to erase that stored memory after every print
Would M502 be the correct command?
@nick_durrett Are you providing enough power to your sensor? I had an issue with my printer never having the same Z offset from day to day and it drove me nuts. It was caused by supplying only 5v of power to it when it needed at least 6v. I rewired the power to the sensor via Tom’s Guide on Auto Bed Leveling (Tramming) and the Z offset been exactly the same ever since. The only time it needs to be changed is if I have changed something on my bed or carriage.
