Z Seam manual input ignored....

[StealthPrint]

When I try to manually set the Z-seam location when I slice the file it is ignored and preview shows the seam at a corner as it would when selecting "optimized"

I'm trying to calibrate pressure advance. File is a 100mm cube, 1.2mm walls (0.6 nozzle). Trying to generate the seam in the middle of a side of the cube. No matter what combination of X/Y values I input they are disregarded. It simply selects the closest corner to the X or Y coordinate that I select.



I tried moving the X coordinate 10mm at a time, once I input a value beyond the middle of the wall (X>250), the retraction location jumps to the right corner of the model, anything less than the middle (X<250)

Yes, it lands at the nearest corner. If you want it to land in the middle of the flat surface, there needs to be a discontinuity in the STL file. I've added a tiny groove on a flat wall to force the zipper to land in the center.
