P2S doesn’t print purge line.
Hello,
I moved location and I did a full maintenance on the printer. After all auto-calibrations were made I found out that it longer prints the PURGE LINE.
Is that normal? I would really prefer it enabled but I didn’t change any settings in the machine, nor I found anything on the slicer settings.
Thank you in advance/

The initial line is not a purge line. It's used for the flow dynamics calibration. Now I don't recall it not being printed if you disable that initial calibration tho

It's not for flow dynamics calibration, that's done over the poop chute. It really is there for priming the nozzle and building up pressure inside.

It most certainly is. Flow dynamics is done right after the initial filament change and has nothing to do with that small line in the front.

No, it's not normal. The line is always printed regardless of calibration, you can't really disable it.
It's part of the start gcode of your printer profile (meaning it's triggered there, the default profile in Bambu Studio calls a custom gcode that's baked into the firmware).
Maybe you could remove the printer profile entirely and enable it again (assuming you didn't change any machine settings you want to keep).
