coreflake1/guppyscreen v1.3.0-OpenKE

v1.3.0 — OpenKE

on GitHub

What's new in v1.3.0

Touch calibration accuracy, WiFi reliability, file browser fixes, UI polish, and a full wiki redesign.

Touch calibration overhaul

• 3-tap averaging — each crosshair now collects 3 taps and averages them, reducing finger-position noise by ~1.7×. Combined with improved symmetric crosshair geometry, total accuracy is ~2.2× better than v1.2.x.
• Reset Touch Calibration — new button in Settings → System Info to re-run the 9-tap wizard at any time (e.g. after changing display_rotate).
• Double-rotation bug fixed — calibration data is now stored in pre-rotation space; coefficients survive orientation changes correctly.

WiFi panel — reliability improvements

A full audit of the WiFi connection flow:

• Network scan now waits for the list to stabilise (up to 5 rounds) so all nearby networks appear
• Auto-scans on first open — no need to tap Scan manually
• IP address only shown after layer-3 is confirmed (gateway ARP reply), not just association
• Password eye-toggle to reveal/hide while typing
• Saved-network connection now shows "Connecting…" feedback
• REASSOCIATE used when switching networks — no reboot needed
• Various race conditions and guards fixed

Factory reset improvements

• USB emergency factory reset — works even with a black screen or dead SSH: create an empty file named emergency_factory_reset on a FAT32 USB drive, plug it in while powered off, power on. The printer resets itself and reboots to stock.
• New Reset Options submenu in Settings → System Info combines Factory Reset and Reset Touch Calibration in one place.
• The factory reset service (S58factoryreset) is now deployed by the installer automatically.

File browser

• USB files now load full metadata (print time, filament) and thumbnails via metascan
• File selection was blocked for USB files — fixed
• Debounced refresh prevents double-taps from corrupting the list

UI polish

• Dialog buttons: safe action left, destructive Confirm right in red — consistent across all dialogs
• LED panel: scrolls correctly when 3+ LEDs are configured; binary LEDs get a toggle instead of a slider
• Fan panel: scrolls correctly when 3+ fans are configured
• Numpad: backspace-to-dismiss now works reliably
• Console: capped at 100 lines, Klipper temperature spam filtered
• Print status: spurious scrollbar artefact removed
• Exclude object: polygon outlines + accurate point-in-polygon hit-testing; last-object cancel shows a clear "Cancel print?" dialog

Logging

• Default log level changed from debug to info — logs now last weeks instead of hours
• warn level added to the dropdown in Settings

Installer / uninstaller

• Uninstall now correctly removes S58factoryreset, restores S50dropbear if backed up, and cleans up rc libs
• reinstall-creality.sh removed — use installer.sh uninstall instead (they were identical)

Wiki

Full redesign for v1.3.0 — restructured around a clear user journey, every setting in every screen documented for newcomers, six outdated pages retired, and the first-layer calibration guides split into logical A→B steps.

Upgrading

Run the installer again — it's safe to re-run on an existing install:

sh -c "$(wget --no-check-certificate -qO - https://raw.githubusercontent.com/coreflake1/guppyscreen/main/scripts/installer.sh)"

Or use the on-screen updater (Settings → Update) if you're already on v1.2.x.
