Cartographer3D + display_connector - screen freezing during scanning

[oley83]

Hello,

after update cartographer-klipper (old plugin) to cartographer3d-plugin (new plugin) and display to v0.0.0-147-gfc843263-inferred during scanning display freezing in scanning view.

With AI help I changed a few lines of code in the display.py file:

Oryginal:
elif "Beginning rapid surface scan" in response or "Touch home at" in response:
# Rapid scan mode (Eddy/Cartographer/Beacon) - these probes don't send
# "Adapted mesh bounds" or "probe: at" messages, so we handle everything here
self._rapid_scan_mode = True
self.bed_leveling_probed_count = 0
self.bed_leveling_last_position = None
self._bed_leveling_complete = False
# Reset leveling_mode for KAMP during printing
if self.current_state in ("printing", "paused"):
self.leveling_mode = None
logger.info("Rapid scan mode detected - using simplified visualization")
current_page = await self._get_current_page()
if current_page != PAGE_PRINTING_KAMP:
self._loop.create_task(self._navigate_to_page(PAGE_PRINTING_KAMP, clear_history=True))
self._loop.create_task(
self.display.update_kamp_text("Scanning bed surface...")
)

Changed:
elif "Beginning rapid surface scan" in response or "Touch home at" in response:
self._bed_leveling_complete = True
self._rapid_scan_mode = True
return

Now display don't freeze during scanning.
There is probably some error in the display.py file
