[BUG] Unable to invert extruder stepper direction #20259

Closed phil1horton closed 3 years ago

phil1horton commented 3 years ago

Switched out the extruder stepper for my Tevo Nereus with a Makerbase MKS Nano 1.1 mainboard using marlin bugfix 2.0. The original stepper has one gear that drives another gear to moves the filament. I switched it to a stepper that drives the filament directly so it requires that I invert the direction. I went into configuration.h and updated the following fields below to switch the direction and nothing changes aft boot up.

// @section extruder

// For direct drive extruder v9 set to true, for geared extruder set to false.

define INVERT_E0_DIR true

define INVERT_E1_DIR false

define INVERT_E2_DIR false

define INVERT_E3_DIR false

define INVERT_E4_DIR false

define INVERT_E5_DIR false

define INVERT_E6_DIR false

define INVERT_E7_DIR false

Did you tried clear the EEPROM with M502?

Hello Chip,

I updated the firmware in visual studio and loaded the MKS nano from a thumb drive, and watch the printer load that file. M502 not needed.
