Spiral Z-Hop can carry nozzle outside of printable area

[MiniMook]

OrcaSlicer Version

1.8.1

OS version

Windows 11

Additional system information

Ryzen 7 5800X 32GB RAM

Printer

Voron Trident 300mm

How to reproduce

1. Load up an object with less than 1-2mm of clearance from the edge of the printable area. I was printing stealthmax parts from https://github.com/nevermore3d/StealthMax on a 300mm Trident
2. Slice using the configuration Printer Settings -> Extruder -> Z Hop Type set to "Spiral"
3. Print file

Actual results

After a couple hours in you may get an automatic print cancellation with the error similar to:

Move out of range: 127.384 -0.033 2.662 [14001.338]

Defining a negative Y value, which is obviously bad.

Expected results

Printer should complete the print without issues.

I would suggest using G2 or G3 for spiral wipes moving towards the center of the bed, rather than always a G3

I thought I had the same issue but could not reproduce it.

A print failed at the shown layer in the z-hop spiral. With a Move out of range: -0.019 263.662 23.287 [140557.543]

But only a small part of the print but at the same exact position worked just fine.

Current best theory is, that the skew correction I use causes this. The part is so close to 0 that this small change from the skew causes the problem. Assuming you are using klipper, this should solve it. Thanks to Mikl Schmidt for this!

position_min: -1.5

I also have shrinkage compensation enabled for the material. This also makes the part bigger.

Confirmed. I added the position_min and ran the same gcode again and it worked without problems.
