Application Version

4.13.1

Platform

win10

Printer

custom fff

Reproduction steps

Not sure, see the attached project. Combing is set to off.

Actual results

I can't tell if this is an issue in arachne since it uses so vastly different pathing so I'll post this just in case.
Nozzle visits a point without doing anything, before continuing to next area.

I think it's due to monotonic ironing order being enabled. Looks like it's travelling to where it thinks the ironing will start but then the monotonic ordering kicks in and it goes off elsewhere.

[printingotb]

Yep, doesn't happen if I turn off monotonic ironing.

Hi @printingotb thank you for your report.
I think this is related to the other issue related to Monotonic Ordering you reported a while a go: #10824 and we have a ticket on our backlog related to the travel moves with monotonic. I will link this ticket as well.
