Currently my 3D printer starts all projects from the lower left corner of the heatbed. I want to change the default setting to make the center of the heatbed the default position.

However, I have not found any documentation on how to do this. Can you help?

    $\begingroup$ Why you want to do that, please explain, that makes no sense at all. Your project starts where you slice it. You can change it, but you need to change the firmware. And if you have done so you need to change the settings of the slicer also. $\endgroup$

    $\begingroup$ Isn't this set within whatever sliver you use, and the position of the piece on the bed? $\endgroup$

    $\begingroup$ Technically, Recalibrating Home-position may answer your question: you re-define 0 as the central bed position via trial and error, and need to swap the slicer to treat center of bed as 0 (which is a machine setting in cura) $\endgroup$

    $\begingroup$ My initial comment was meant to ask for an explanation why you want to set the origin in the middle of the bed, this is absolutely unnecessary, but you can do it. It is most certainly not a duplicate as it requires the firmware to be differently setup, e.g. use define BED_CENTER_AT_0_0. Only when this is set the firmware will work with half size bed length and width as you now need half bed sizes to go in positive and negative direction. Also the slicer needs to be adjusted for a center bed setup. This needs to be reopened, comments cleaned and the OP to add some additional info. $\endgroup$

You don't need to change the printer.

Usually, the front left corner of the build plate is the origin (for 98 % of all printers, and certainly this printer), or (0, 0) coordinate. When you slice and object in the middle of the build plate, it should be printed in the middle. If not, if the print is built treating the center of the bed as (0, 0), and prints at an offset of that location, than you have your slicer incorrectly configured. Make sure not to setup the slicer to treat the center of the bed as the origin. If you change that, you will be able to print where you slice it on the plate.

There is absolutely no benefit to make the printer bed center the origin, you are facing an incorrectly configured slicer.
