I just confirmed that when a model is placed in the slicer for example front center 2 inches from front.
When printed it is at rear center 2 inches from rear only rotated 180 but not mirrored.

@timcurtis67 If i invert my motors on Y the bed moves forward looking for home however the endstops for y home are at the rear of the printer Unless I mis understand invert...

@timcurtis67 Y endstop is at rear of printer, when y homes the bed is towards the rear of the printer.

@timcurtis67 In the web control, Z moves up with a Positive value from the head movement controls, X and Y want a - value to move away from home.

@phaedrux I'm using simplify 3d and the bed is set up for 300x 300y 300z same settings as with a mini rambo and on other versions or ramps with marlin.

Here is my specific issue at hand.
Running the Duet wifi my homing works well reporting back from the web console X300 Y300 Z0. Printer set up is a cartesian, bed dimension is 300x300.

Z endstop is at lower front left of bed, Y endstop is at bottom rear of printer, X endstop is on left of maching and travels with Z motion.

What is required so that models print the same as placed in the slicing app. I've never seen this problem before.

Any help will be appreciated.
