Firmware Setting (e.g. Marlin firmware)
Please update the firmware in the following order:
Step 1: Copy the file below and overwrite at the Marlin folder. <== e.g. default
Marlin-bugfix-2.0.x\config\default\Configuration.h
Marlin-bugfix-2.0.x\config\default\Configuration_adv.h
Step 2: Look at the Configuration.h at your previous firmware and edit Configuration.h at Marlin.
Step 3: Check your 3D printer works well.
Step 4: Please install your BLTouch.
Step 5: Edit Configuration.h and Configuration_adv.h like below.
