PrusaSlicer World Coordinates

Do you know the X & y world coordinate values for the bed center on beds 2 thru n? 

I use the world coordinate values for bed center a lot. I know that x=125, y=125 are the bed 1 center values....

Has anyone determined the bed center value in the world coordinate system for the additional beds?

Thanks. 

PrusaSlicer world coordinates in mm for center of beds 1 thru 9 for MK4 are as follows in the format of bed# = X, Y

1 = 125, 105   2 = 820.9, 720.9   3 = 472.95, 720.9   4 = 125, 720.9   5 = 820,9, 412.95   6 = 820.9, 105   7 = 472.94, 412.95   8 = 125,  412.95   9 = 820.9, 720.9

RE: PrusaSlicer World Coordinates

I don't know off the top of my head, but you can figure it out yourself. Open Prusa slicer. Add a primitive shape (doesn't matter which). Select it, copy to the clipboard and paste 8 times (or increase the instances to 9). Drag one of each to all 9 beds. Cycle through each bed and use the Arrange current bed tool (upper tool bar, 4th icon from left or keyboard shortcut "D") to put each object on the center of each bed. Then just select them and copy the x/y coordinates. I did this for C1+ and found at least for that printer bed shape (probably very similar to the MK4) they aren't on even mm increments. For example, the center of bed 6 appears to be 824.81,429.9.
