Feature Request - #define Z_DUAL_STEPPER_DRIVERS #127

Closed juliogdiana closed 7 years ago

juliogdiana commented 7 years ago

Looking to enable dual Z stepper drivers for Ultimaker when you have only one extruder.

Unfortunately my Z stepper crooked and i am looking to use the spare extruder stepper to control the Z axis.

I know it is possible on RAMPS 1.4 but I cant get it to work on Ultimaker board.

I have defined this on adv.h

define Z_DUAL_STEPPER_DRIVERS

ifdef Z_DUAL_STEPPER_DRIVERS

undef EXTRUDERS

define EXTRUDERS 1

endif

But I am getting error on pinout after verify

Any help will be appreciated

This isn't a feature request but a standard support question. Please ask support questions at the Ultimaker forum since more people there are able to help you.

The Z_DUAL_STEPPER_DRIVERS function seems to be broken in the Ultimaker Marlin. It's not a function we are planning to support and most likely will be removed from a new version. Easier change for you is go to pins.h and change the first Z-axis to use the pins from the spare motor driver. In pins.h change:

define Z_STEP_PIN 46

#define Z_DIR_PIN          48
#define Z_ENABLE_PIN       63

into:

define Z_STEP_PIN 36 // 46

#define Z_DIR_PIN          34    // 48
#define Z_ENABLE_PIN       30    // 63
