I'm working on getting my printer to make simple movements. To test some simple movements I added some simple GCODE to move in a straight line on the X and Y axis. But for some reason, my printer thinks it has to move a huge distance before it does that (See the Green line on the page). The GCode is pretty straight forward so the issue isn't there. Next i thought that the printer configurations werent centered at the origin but i can't seem to find where this would be stored.

Does anyone know what could be going on here?

My GCode is super straightforward, it should just move down and make a cross. For some reason it wants to move left a looooong distance first

maybe try a G28 as the first command to home the printer?

I don't have my end stops configured yet, so I won't be able to home :/

What positioning mode is set by default?

G90        ;absolute positioning
G91        ;relative positioning

Try to set your slice starting location to 0,0 if you are using a delta printer. I had the same issue when I started printing with mine. Some slicer assume you have rectangle printing bed and starts to print at the center (i.e. 70,70), causing out of bound errors.
