When Left is Right and Right is Left

[wetsparks]

Having a problem with the above. I slice a Left Handed print but on the printer it prints out as Right handed and the same for a Right handed print, prints as a Left handed one!!

I've tried altering the controls in Options but it doesn't seem to make any difference. The printer is an Arduino / Ramps 1.4 dual head set up.

Under Process Settings => G-Code check your "Flip build table axis" settings

Thanks for the reply. I've played with that setting this morning and all it does is change the hand that is viewed, but makes no difference to what happens at the printer. It is still reversing the hand that is sent to it. Could this be a Marlin issue? If so any ideas where?

So originally, you said that the way the parts looked in the software and what was printed on the machine were backwards. So if you toggle the "flip build table axis" option for the Y-axis, that will fix that. So at that point, the parts should look the same in the software as they do when they are printed.

Now if you still think that is backwards from how you want it, then at that point, you have to go mess with the firmware, because that's what determines what direction the +Y axis is. There's options in the firmware's configuration files to invert the axis movement directions.
