Questions tagged [automatic-bed-leveling]

Use this tag for questions regarding the automatic leveling of the build platform.

The automation of the process of bed leveling is frequently used with some sort of a sensor to sense the distance to the platform; such a process is referred to as Auto Bed Leveling (ABL). These sensors scan the build surface to compensate for local or global surface deficiencies.

Weird bed movement when doing ABL (G29)

My printer recently started lowering the bed an additional step for every measurement on the G29 procedure. The only change I did, at least purposely is, adjusting the nozzle offset and MIN/MAX positions for X and Y because I installed the "Hero Me"…
