How to set home offsets in Marlin firmware?
View the current offsets with M503. If EEPROM_SETTINGS is enabled, the home offsets are saved with M500, loaded with M501, and reset with M502. M428 sets home offsets so the current position aligns to the native home position.
How to enable automatic bed leveling on Marlin G29?
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. After a G29 bed leveling is automatically enabled, but in all other situations you must use M420 S1 to enable bed leveling.
Where is the leveling data stored on a Marlin bed?
If you find that the leveling isn’t very accurate, use M48 to test the accuracy of the bed probe. After a G29 the leveling data is only stored in RAM. 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.
Is the bed leveling still off after a reboot?
After a reboot, and a G28, bed leveling is still off, and i need to turn it on manually. Additionally, after doing G28, G29 L1, G29 A, G29 S1, M500, the leveling on/off item disappears from the menu until the next G28.
How to manually set home position in Marlin?
In configuration.h, line 866 (on Marlin RC8), remove the comments (by deleting the “//” at the beginning) for each axis you want to manually set a position for. Then enter your desired value by replacing “0” with where you want your home positions set: // Manually set the home position. Leave these undefined for automatic settings.
How do you set an offset on a home?
Use M206 to apply a persistent offset to the native home position and coordinate space. This effectively shifts the coordinate space in the negative direction. See examples below. The current position is adjusted to align to the new home offset values.
Is it possible to change the z offset in Marlin?
But it is possible to do it with software. You can not only change the Z offset in the slicer or in the configuration of Marlin, but also with G-code commands. The “paper drag” method is perfect for determining the correct Z level.
