Questions tagged [homing]

For questions regarding the "homing" (positioning to a known location) of 3D printing devices.

The process of determining the location of a 3D printer nozzle in three dimension using a reference point (home location) is referred to as "homing". Homing should occur before every print and involves bringing the X, Y and Z-Axis motors to predefined limit locations (usually these are end stops). Pre-recorded homing data offset values determine the position of the build plate origin with respect to the end stop locations.

Use this tag for all issues related to or during the process of homing a 3D printing machine.

How to center my prints on the build platform? (Re-calibrate homing offset)

When I print large prints close to (but not exceeding) the maximum dimensions of the heated build platform on my Anet A8, the brim or skirt or the print itself is printed outside the heated bed, while there is some space left at the opposite sites.…

What are the pros and cons of using a BLTouch in place of a limit switch?

This is about practicality. I'm hearing that people are using their BLTouch not to adjust the Z offset, but as the limit switch for the machine! Why is this so? What are the pros and cons of using a BLTouch (or any touch sensor for that matter) in…

Ender 3 V2 ignories Z-axis limit switch

My shiny new Ender 3 V2 seems to ignore the Z-axis limit switch, when I print a model. It moves the nozzle so far down, that it scratches on the bed and destroys the nozzle. However, when I use the Auto Home function it lowers the nozzle until the…

Why the Ender 5 Pro can't remember the axis position or cant move back to home anymore?

I am completely new to 3D Printing. I got my first printer a Creality Ender 5 Pro yesterday. My problem I did shutdown the printer without the axis being in home position (X: 0, Y: 0, Z: 320 instead of X: 0, Y: 0, Z: 0). I thought this should be no…
