E1 question[SOLVED]

in marlin or where ever how do i change the 2 z and put it on e1 instead of having one driver sharing the load can have them both seperate?

Are you saying you want to run the two Z motors off of separate drivers?

Although that would be technically possible, I doubt that it's a configurable option. Seems to me that would be a significant change to the firmware. Besides, don't you need E for your extruder?

i found this lulzbot yes becasue my z driver get hotter than others on 0.4 vrefand i have e0 and e1 and only going to have one extruder so it is possible going explore the link abit more

if i un-comment this like i have done will this allow me to use e1 as one of my z

do i need to do anything with the bold bit

// A single Z stepper driver is usually used to drive 2 stepper motors.
// Uncomment this define to utilize a separate stepper driver for each Z axis motor.
// Only a few motherboards support this, like RAMPS, which have dual extruder support (the 2nd, often unused, extruder driver is used
// to control the 2nd Z axis stepper motor). The pins are currently only defined for a RAMPS motherboards.
// On a RAMPS (or other 5 driver) motherboard, using this feature will limit you to using 1 extruder.
#define Z_DUAL_STEPPER_DRIVERS

#ifdef Z_DUAL_STEPPER_DRIVERS
#undef EXTRUDERS
#define EXTRUDERS 1
#endif

"in marlin or where ever how do i change the 2 z and put it on e1 instead of having one driver sharing the load can have them both seperate?"

you need to configure your pins.h find your controller board number in that list and change the E1 pins to match the Z pins and voila. you will stell use E0 For extruder and e! for second Z driver. I have mine configured this way, works great

solved i just uncommented #define Z_DUAL_STEPPER_DRIVERS

I want to do something similar but use the E1 to drive the Y axis, any suggestions?

Solved my own question there, I changed the pin definitions in pin.h could be an alternate solution to the previously solved problem also.

Sorry for resurrecting an old thread but I'm trying to do this and need a bit of clarification.

If I read you right below, this is what you mean to do (in the pins.h file)?

My Z pins currently read like this:

#define Z_STEP_PIN 46
#define Z_DIR_PIN 48
#define Z_ENABLE_PIN 62
#define Z_MIN_PIN 18
#define Z_MAX_PIN 19

And my E_1 pins currently read like this:

#define E1_STEP_PIN 36
#define E1_DIR_PIN 34
#define E1_ENABLE_PIN 30

So, I should make my E_1 pins read like this?

#define E1_STEP_PIN 46
#define E1_DIR_PIN 48
#define E1_ENABLE_PIN 62
#define E1_MIN_PIN 18 (add these lines?)
#define E1_MAX_PIN 19 (add these lines?)


OR, If I just un-comment the Dual Stepper command in my Configuration_adv.h file (change this; //#define Z_DUAL_STEPPER_DRIVERS to this; #define Z_DUAL_STEPPER_DRIVERS) will I not have to mess with the pin change above and it will automatically know I'm using the E1 socket to drive the second Z motor?

I'm on the same train.

By now, uncomenting #define Z_DUAL_STEPPER_DRIVERS gives me an error:

Configuration_adv.h:165:4: error: #error "You cannot have dual drivers for both Y and Z"


And I don't have the dual Y enabled

Its strange, i done the same and works like charm for me, no errors at all.
First what Marlin you use, what arduino ide?

Okay, solved this.

Added the Z2 pins to the rumba definition in pins.h.

What did you add to pins? i'm stumped on this.

@Mawright89

I added the following code to the RUMBA section in pins.h:

// Added by ePoxi
#define Z2_STEP_PIN        26
#define Z2_DIR_PIN         25
#define Z2_ENABLE_PIN      27

Can you help... Just wondering what file you uncommented the line?
Is it Configuration or Stepper?

Thanks.

Configuration_adv.h, line 146 if you are on the latest version of ErikZalm's stable branch. Other branches may have it at a different line but it should be around there if they are recent and include the feature.
