Robin E3D with EXP-MOT3 #121

Closed countcobolt closed 3 years ago

countcobolt commented 3 years ago

Hi all, is it possible to use the EXP-MOT3 on a Robin E3D? I use EXP3 for my standard Ender type screen, so exp 1 & 2 are open. What files need to be modified in marlin? Using 2.0.6.1 from this branch. I would like to use this to

  1. Add an additional extruder
  2. Separate my Z-steppers so I can use G34 for levelling.

kind regards

  1. If you use MKS EXP-MOT3 on E3D, you need's use EXP3 interface
  2. You need set it. For example： You need use X2 axis： A. Configuration_adv.h file: enable #define X_DUAL_STEPPER_DRIVERS B. pins_MKS_ROBIN_E3_common.h add pin define（On M1） 
    #define X2_ENABLE_PIN  PC1//BEEPER
#define X2_STEP_PIN  PA4//LCD_EN
#define X2_DIR_PIN  PA5//LCD_RS

Stupid Question, but where do I then set up the LCD display?

If you must connect your lcd on e3 board, you can use MKS EXP-MOT3's M3 interface image

sorry to keep on asking stupid questions, but I only see EXP1 & EXP2 on the MOT3

Hi all, do you mean : if you need to use exp3 you CAN NOT use the lcd or can? Sorry not clear to me
