AC Heater flicker light when heating up the bed.
In the heater section of Klipper printer.cfg add below code, this should reduce or remove flicker.
pwm_cycle_time: 0.02
Save and restarting configuration and try bed heater again.
Back up Klipper Configuration
Once printer is calibrated we highly recommenced saving your configuration locally to your computer, as configuration saved onto raspberry pi sd card is not always reliable and depending on SD Card you may loose your configuration due to SD card corruption or failed sd card.

Neo-Pixel Wiring Guide:
Hot Mount Y-Rails (How to improve bed variance)
- Confirm screws on the Y rails are tight.
- Home and QGL
- Move toolhead to the center of the printer, add some Z height to make easier to access the rail screws
- Loosen all the Y rail screws except for the 2 center screws
- Heat soak the chamber for approximately 1 hour to ~55C
- Turn off the bed heater and extruder heater
- Re-tighten the Y rail screws from center outward to the ends of the rails (be careful not to burn yourself)
- Move the toolhead back and check the 2 center screws to make sure they are still tight
- Home and QGL
- Run Mesh
