After upgrading to Marlin 1.1.8 I noticed the printer doesn't run the auto leveling process it did in the past right before each print.
Instructions said to remove the bed leveling gcode, do I need to put it back?
You only need to level the bed every now and then with the firmware update. You can do this by going to the gMax Tools menu and selecting level bed. The mesh will now save and can be used over and over.
If you adjust the BLTouch, you will need to perform a babystep z at the beginning of the print. The babystep will be temporarily saved until the printer is powered down. You can permanently save the babystep z by going to Menu>Control>Store Settings. You will hear a beep sound to indicate that it is saved.
