Marlin: Ramps 1.4 with all TMC2130, dual Z steppers, only one is moving.

Created on 21 Apr 2018 · 12Comments · Source: MarlinFirmware/Marlin

Description

I've got a Ramps board populated with TMC2130 drivers, I enabled Z_DUAL_STEPPER_DRIVERS in config as well as X, Y, Z, E0 and E1 as _IS_TMC2130
unless I understood it wrong this should automagically sync movement on Z and E1(as a Z2)
but that doesn't seem to be the case.

M122 reports all drivers to have stealthChop enabled (they don't with 12v rail off, so I take this as a confirmation SPI comms are hooked up and working 100%)

Steps to Reproduce

Enable X, Y, Z, E0 and E1 as _is_TMC2130
Enable Z_DUAL_STEPPER_DRIVERS
Compile and upload
Expected behavior:
When moving Z I expect both to move in unison

Actual behavior:
Only the stepper hooked up to Z moves.

Your settings are wrong and why is disable HYBRID_THRESHOLD?

Configuration_adv.h

#define HAVE_TMC2130
#if ENABLED(HAVE_TMC2130)  // Choose your axes here. This is mandatory!
  #define X_IS_TMC2130
  //#define X2_IS_TMC2130
  #define Y_IS_TMC2130
  //#define Y2_IS_TMC2130
  #define Z_IS_TMC2130
  #define Z2_IS_TMC2130
  #define E0_IS_TMC2130
  //#define E1_IS_TMC2130
  //#define E2_IS_TMC2130
  //#define E3_IS_TMC2130
  //#define E4_IS_TMC2130
#endif

pins_RAMPS.h

add this code

#ifndef Z2_CS_PIN
  #define Z2_CS_PIN        -1 // Change PIN
#endif

Once you've figured out the right settings, be sure to test with the latest bugfix-1.1.x (and/or bugfix-2.0.x) branch, as these are more complete than previous Marlin versions.

Okay, thanks to the changes suggested by Ludy87 and thinkyhead I have the z2 axis working.
now I struggle with X axis not moving, it holds the motor in places but I can't move it... I think maybe the socket is fried, moving the TMC drivers around it's the only one not working and when it holds the motor it gets really hot.

anyway in regards to Z2 maybe have better comments on how it works in the config section and maybe leave the

#ifndef Z2_CS_PIN
  #define Z2_CS_PIN        -1 // Change PIN
#endif

inside pins_ramps.h

Change the pinout according to your board.

-1 is a placeholder

Ludy87 on 21 Apr 2018

of course I did, I am not that dumb ;)

it's working now, but I've managed to fry one of my tmc2130 boards, guess I'll use ordinary DRV8825 for extruder :/

many thanks to all for this awesome configurable/customizable fw

Frying boards is par for the course in RapRap-land! It's good to have a box of spares.

I am having a similar issue with dual Z steppers, only one is moving. I used the same config, on 1.1.8 and this bugfix branch. It worked on the 1.1.8 version but not on the bugfix branch.

I have uploaded the config. http://gofile.me/4eAyF/nTw0xIep7

The problem on 1.1.8 was with XY homing otherwise I would have not switched.
