How often do you level print bed?

You can get away with leveling the bed every 5-10 prints depending on how stable the bed is and how careful you are when removing the finished prints from the surface. In order to stay on the safe side, it is advisable to level the bed before a large print (15 hours or longer) to ensure that it doesn’t fail mid-print.

How to enable auto bed leveling on a 3D printer?

To enable auto bed leveling, we will need to edit the profile for your 3D printer. If you are using a new printer for the first time, you can download the stock Simplify3D profile for your machine by going to Help > Configuration Assistant from within the software.

Is there a way to auto level a printer?

Running Auto Bed Leveling can be achieved in multiple ways. If your printer is already connected to Pronterface, run the G29 command and the Printer will start probing the bed. If you installed the custom screen firmware, then navigate to Menu -> Movement -> ABL and touch the ABL icon. This will go through the same leveling process.

What’s the best way to auto level a bed?

Bilinear Grid: Probe the bed in a grid and apply mesh-based compensation. Best for an irregular bed. Unless you know you have a very flat bed, you should always use AUTO_BED_LEVELING_BILINEAR. And if you have an LCD and enough program memory, you should also enable LCD_BED_LEVELING to add a Bed Leveling sub-menu to the LCD.

How do I reset my bed leveling settings?

You have to use M500 to save the bed leveling data to EEPROM, otherwise the data will be lost when you restart (or reconnect) the printer. Use M502 to reset the bed leveling data (and other settings to defaults). Use M501 to reload your last-saved bed leveling from EEPROM. This is done automatically on reboot.
