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"…

Levelling Data Exception on Ender 3 V2 Neo

I was having problems where the nozzle was shaking on my Ender 3 V2 neo, so I tightened the screws holding to where the nozzle was mounted (which were quite loose), but then when I tried to print something, I got the error: "Leveling data exception,…

Monoprice MP Mini Delta adding glass bed

The bed adhesion is going from already mediocre to unusable. So I got my glass plate. With my previous printer I really liked printing PLA on a 60 °C alcohol-cleaned bed. The problem that I am having, is that the auto-leveling procedure fails. The…

First layer disaster: auto-leveling the bed. Need guidance

I have been printing on and off for years. Generally, I have had no issues until recently. Upon thinking back I don't think I used the Z-offset at any point and only manually leveled my Ender 3 S1 Pro. I'm not sure if it's material or me, or both. I…

Why is the Z probe offset easily adjustable in the printer UI, but not the X/Y probe offset?

I should mention that this is my experience with Marlin. I can adjust the Z offset all I want in the UI, but not the X/Y offset. If you reinstall the probe, I've heard you may need to adjust the Z offset (makes sense, you might not mount in the…
