machine_centre_is _zero = True, has bugs for print tower location (Cura 2.3 and Cura 2.4 beta)

[Dagnall 0]

Although this bug has come up in another topic,

I thought i would start a new simple topic just to record this bug so the developers can sort it.

The Print tower position is incorrectly shown when machine_centre_is _zero = True

The image below shows a print tower at 60x,40y (as it set it in the dual extrusion positions tab).

BUT, the greyed shadow in bottom left quadrant, just below and to the left of the printed items, is where Cura "thinks" the print tower is for slicing. Placing items here causes slicing for that item to be stopped.

Obviously the print tower locations have not accounted for 0,0 offset to the middle of the printbed when "machine_centre_is _zero = True"

Cura will not accept negative values for the print tower, so obviously it does not properly recognise the effects of "machine_centre_is _zero = True"

The Json I used is just the Ultimaker_Original_Dual_Extrusion, but with these changes:

 

"platform": "kossel_platform.stl", "machine_center_is_zero": { "default_value": true}

 

I found this in 2.3, and reported it, but I was hoping that 2.4 might have corrected the bug, but its still there....
