Change the start point of layers in S3D?

[Matthew Neesley]

Simply3d has this IRRITATING habit of changing layers EXACTLY where I don't want it to.  For example, in the attached image, I DON"T want the layer change to happen on the circular edge/face.  Anyone know how I can stop this from happening? I want it on the flat face.  I have tried changing the "Start Points" setting to "closest to 0,0" or even "25,0" but I can't make it happen.  Any helpful advice?  Thanks in advance!

If you want S3D to start/stop each tool path in a specific spot it CAN do it to a point.

In the Process, go to the "Layer" tab. Lower right corner you'll see the box with the title "Start Points" Select "Choose start point closest to a specific location" and enter the X Y values where you want it to happen. I recommend you orient the object so it's real easy for it to put it where you want it such as a corner, if on a long plane don't expect it to work consistently in the same spot..I sometimes add another object like a column and move it to  the spot where I want it to happen and get it's XY location just to be sure I'm oriented correctly. I then remove it. You can also verify it in the preview by looking carefully at your tool moves at the layer change.

I know it isn’t S3D, but I’ve been playing with the latest version of Prusaslicer (v2.3), and have found they have an awesome “Seam Painter” function where you can paint where you want your layer start or end points to be on all or any part of the model. Where you don’t paint, it follows the global settings you have selected (such as aligned to the sharpest corner, random, etc.). You can also paint with the other mouse button to identify where you definitely don’t want the start/end points to be, to make the system find somewhere else.

They also have support painter, which works more or less the same way, but for supports, and is probably the best implementation of this idea I have seen.
