Configuration and Safety

• Backup EEPROM/settings before flashing.
• Verify correct motherboard, MCU, and pin mappings in firmware configuration.
• Thermal safety: enable and test thermal runaway protection, sensor type matches hardware.
• Motor/current and stepper drivers: ensure microstepping, current limits, and driver type match board firmware and hardware.
• Endstops and probe config: confirm homing directions and probe offsets.
• PID autotune, acceleration & jerk—safe defaults and progressive tuning procedure.
• Firmware size and features: ensure build fits MCU flash.

5. Troubleshooting Common Issues

• The screen stays blue or black:

  • Ensure the firmware matches your specific motherboard (SKR vs. Generic).
  • Try a different SD card. 3D printer bootloaders are notoriously picky about SD cards; smaller cards (4GB-16GB) generally work better than 64GB+ cards.
  • Make sure the file is in the root of the SD card, not inside a folder.

• Touchscreen stops working after custom firmware: The Ultimate Guide to Two Trees Sapphire Pro

  • If you flashed a custom Marlin build but kept the stock screen, the screen firmware might be incompatible. You will need to find the specific screen firmware files that match your custom mainboard firmware, or revert to stock mainboard firmware.

• Thermal Runaway Error:

  • If this appears immediately after an update, it usually means the new firmware has the safety feature enabled, but your heating cartridge or thermistor is loose. Check your hotend hardware before blaming the software.

Issue 3: “No Printer Connected” When Using USB

Cause: Serial port incorrect or baud rate mismatch.
Fix: In Configuration.h, set #define SERIAL_PORT 2 and #define BAUDRATE 115200 or 250000. Configuration and Safety
