I am having an issue with prints set on the right side of my printer bed. I have leveled the bed, have a BLTouch and used a bed visualizer just to try and get it manually as level as possible. You can see the problem on the right piece side of this print where the filament was not laid flat and has many "humps" unlike the left piece side of the print that printed smoothly. Any idea what could cause this on an Ender 3 Pro and how to go about fixing it?
Your bed level according to the sensor and reality is changing between the time of probing and the time of printing. There is not enough info to determine exactly where the problem is, but the possible causes and solutions are most likely:
Bed or X-carriage is mechanically loose: ensure all axis and parts of the printer are tight, including the hot-end mount
Bed temperature changes have affected the bed level: ensure the bed is at operating temperature during all manual and automated leveling
Sensor is not reading correctly across the entire bed due to the magnetic sensitivity of the bed or hot-end heating elements: either enable the PROBING_HEATERS_OFF compile-time feature in Marlin or disable the bed and hot-end heaters immediately prior to the automated bed leveling procedure using the code:
M140 S0; set bed temperature target to zero
M104 S0; set hot-end temperature target to zero
then turn them both back on to your desired temperature immediately afterward probing using the same M104 and M140 command syntax to their respective desired temperatures
