How to change print start point/coordinate system origin

PuddingBaer91 · 23 Oct 2018, 10:59

Hi there,

i successfully upgraded to my new duet wifi and it is awesome. It is worth every Cent

Okay if i home my axes the Printer will move to the left front Corner where my endstops are. But for homing z it will move to the opposite corner (right back). Prints will also start from the right back corner. I found out that the coordinate System origin is the right back Corner. But for me it is better to match the coordinate System origin with endstop Position so zero is Zero (Logical). Is it possible to change the location? Is it also possible to let the Printer home z at another Location for example at the bed center?

Thank you

I'm glad you like the Duet! See https://duet3d.dozuki.com/Wiki/ConfiguringRepRapFirmwareCartesianPrinter#Section_Homing_files and https://duet3d.dozuki.com/Wiki/Centering_the_bed_or_setting_the_bed_origin, then ask again if you need to.
