Open luca920 opened 2 years ago

luca920 commented 2 years ago

I am trying to set the board to have dual Y axis, but am struggling in understanding how. Which config lines should I modifiy?

ebraiman commented 2 years ago

Look in pins file for marlin for pins_BTT_OCTOPUS_V1_common.h You might need to rename something like ...

define Z_STEP_PIN PF11 // MOTOR 2

define Z_DIR_PIN PG3

define Z_ENABLE_PIN PG5

ifndef Z_CS_PIN

define Z_CS_PIN PC6

endif

define Z2_STEP_PIN PG4 // MOTOR 3

define Z2_DIR_PIN PC1

define Z2_ENABLE_PIN PA0

ifndef Z2_CS_PIN

define Z2_CS_PIN PC7

endif

To Y2.

Hi @ebraiman, thank you for the answer. I will try.

just to be clear you mean that I should change the block (in this ase I think the one I like) like so:

define Y2_STEP_PIN PG4 // MOTOR 3

define Y2_DIR_PIN PC1

define Y2_ENABLE_PIN PA0

ifndef Y2_CS_PIN

define Y2_CS_PIN PC7

endif

is that right?
