Model Orientation Flipped

[Jeremy Watkins]

This is a bizarre issue, but when I slice a model in Cura and save and upload the g-code to Duet Web Control, the model orientation is inverse to what is displayed in Cura. This is happening on my delta-printer if that makes any difference. Does anyone have any ideas as to what is going on here?

[Jeremy Watkins]

When I say inverse I mean in the sense of a lowercase "b" printed flat on the bed would print as a lower case "d". This is obviously annoying for prints that aren't symmetrical.

@jeremy-watkins That one "axis" has the 0 position on the opposite side the firmware was told. At least that what happens with a cartesian style printer.

It sounds that you have configured your printer to have a left hand coordinate system. You need to change it to a right hand coordinate system, which means that the +Y direction is 90 degrees anticlockwise from the +X direction when viewed from above. If it's a Cartesian or CoreXY printer, you can achieve this by reversing one of the axes. If it's a delta, swap the X and Y motor connections and endstop connections.

@dc42 Thank you, that sounds like an easy fix!
