Marlin 1.1.9, TMC2130 V1.1, no movement

Hi,

after fighting a 32-bit Chinese controller for a year it finally decided to even blow some mosfets, so I now upgrade my printer to a simple RAMPS 1.4 on 24V with TMC2130 V1.1 drivers. Should be nice. I set everything up, all sensors and the hotend are working. Now I need the axles (and the extruder) to move. But they refuse.

I went through the Configuration.h (besides the usual settings for endstops and CoreXY and such), starting at line 540:

 * Stepper Drivers
 *
 * These settings allow Marlin to tune stepper driver timing and enable advanced options for
 * stepper drivers that support them. You may also override timing options in Configuration_adv.h.
 *
 * A4988 is assumed for unspecified drivers.
 *
 * Options: A4988, DRV8825, LV8729, L6470, TB6560, TB6600, TMC2100,
 *          TMC2130, TMC2130_STANDALONE, TMC2208, TMC2208_STANDALONE,
 *          TMC26X,  TMC26X_STANDALONE,  TMC2660, TMC2660_STANDALONE,
 *          TMC5130, TMC5130_STANDALONE
 * :['A4988', 'DRV8825', 'LV8729', 'L6470', 'TB6560', 'TB6600', 'TMC2100', 'TMC2130', 'TMC2130_STANDALONE', 'TMC2208', 'TMC2208_STANDALONE', 'TMC26X', 'TMC26X_STANDALONE', 'TMC2660', 'TMC2660_STANDALONE', 'TMC5130', 'TMC5130_STANDALONE']

In Configuration_adv.h, from line 1081:

/**
 * To use TMC2130 stepper drivers in SPI mode connect your SPI pins to

 * in your `pins_MYBOARD.h` file. (e.g., RAMPS 1.4 uses AUX3 pins `X_CS_PIN 53`, `Y_CS_PIN 49`, etc.).
 * You may also use software SPI if you wish to use general purpose IO pins.
 *
 * You'll also need the TMC2130Stepper Arduino library
 * (https://github.com/teemuatlut/TMC2130Stepper).
 *
 * To use TMC2208 stepper UART-configurable stepper drivers
 * connect #_SERIAL_TX_PIN to the driver side PDN_UART pin with a 1K resistor.

It seems weird to me the enable is false, I don't think it should. But I don't know how to fix that.

I used no jumpers on the RAMPS board (hence the low number of steps per mm you can find above) and I removed the pin following Dir and Step (with the little gear) as I read somewhere that should help. I can easily solder them back, I just heated the pin and pushed it up.

Where to look next? All help is appreciated, I just want to have a reliable printer again after a year of many longer prints failing.

Hugo

Its not talking SPI correctly

how exactly have you wired the SPI bus and to where?

config shows your using TMC_USE_SW_SPI

but that conflicts with pins 44 and 64 below

#if ENABLED(TMC_USE_SW_SPI)
  #ifndef TMC_SW_MOSI
    #define TMC_SW_MOSI    66
  #endif
  #ifndef TMC_SW_MISO
    #define TMC_SW_MISO    44
  #endif
  #ifndef TMC_SW_SCK
    #define TMC_SW_SCK     64
  #endif
#endif

perhaps your using physical SPI port, in which case you should disable TMC_USE_SW_SPI in Configuration_adv.h

Hi,

thanks for the quick response. I have soldered the SPI wires from the drivers to the pins on the connector for the LCD screen:
SDO on the drivers to port D50 MISO
CS goes to the before mentioned ports D40, D41, D44 and D64
SCK on the drivers to port D52 SCK
SDI on the drivers to D51 (MOSI)

I just changed this in the Configuration_adv.h following your comment:

   */
  //#define TMC_USE_SW_SPI
  #define TMC_SW_MOSI        D51
  #define TMC_SW_MISO        D50
  #define TMC_SW_SCK         D52

Taking out the standard pins and defining where they really are.

I uploaded, Marlin rebooted and I got this from M122:

Well its now talking, this is a start.

Do the drivers work if you reset your board without removing power? (reset button) The chip requires its power to be stable before it sees 5V on VCC_IO pin from arduino. There's a chance that 12V on your power supply stabilizes after the processor's power is already up and that will reset TMC2130 settings to defaults.

I wonder why 'Enable' stays false. Is that correct? I changed it:

// For Inverting Stepper Enable Pins (Active Low) use 0, Non Inverting (Active High) use 1
// :{ 0:'Low', 1:'High' }
#define X_ENABLE_ON 1
#define Y_ENABLE_ON 1

#define E_ENABLE_ON 1 // For all extruders

So now it says true:

But still no movement.

microstepping is set to 256 should be 16... (I suspect this is default as you have asked for an illegal option, 1 microstep and Interpolate)

from configuration_adv,h

This is good.
#define INTERPOLATE true // Interpolate X/Y/Z_MICROSTEPS to 256

why is your microsteps set to 1? all these should be should be 16
#define X_MICROSTEPS 1 // 0..256
#define Y_MICROSTEPS 1
#define Z_MICROSTEPS 1
#define E0_MICROSTEPS 1

I just thought the same thing, while eating my pasta. I changed it to 16, changed the steps / mm settings accordingly, and fitted the 3 jumpers under each driver. Nothing changed. But then I put the ENABLE_ON all back to 0, and we have movement! It all moves the wrong way so I need to invert some motor plugs, but it moves. Thanks!

Hugo

Because of the speed limitations I would like X and Y to go to 8 microsteps as those motors are 0.9 degrees, but I'll figure that later... Now first switch the motor plugs and tune eveything so I can print a new spool holder that just snapped off...

Hugo

Well, some progress was made but not everything is working.

- I cannot extrude. Everything is up and running, it seems, but the stepper motor of the extruder won't turn. I also see upon start-up that Marlin echoes to Pronterface: "Filament settings: Disabled". But I don't know where to enable them.

- Another problem is that the communication with the TMC2130s is not stable. I start the printer (and check with M122 that all enables are false) and run G28. This works sometimes, sometimes it doesn't. X and Y homing works, sometimes Z does as well. If Z homing fails, it is due to the Z and E enables coming back true, when M122. If it didn't fail here, then I ask G29 and during this operation it fails. M122 shows some enables have changed to true and everything stops. Resetting the printer works. I am now putting on a 1,5A step-down converter instead of the lonely LM7805 I soldered to the back of the Arduino Mega, hoping this will give a better / more stable 5V. Although the LM7805 should give 1,5A, too, and it is not really warm, I just hope this will fix something...

Hugo

Nothing seems to fix the rather random problem.
- I lowered the currents (maybe it overheats...). No change, but I'll leave it low as the machine moves nicely.
- I changed from 16 to 8 microsteps (BTW, you don't need the jumpers. You can leave them off and define the microsteps in the configuration_adv.h. And off course correct the steps / mm in the configuration.h) I hoped it would make the processor less busy.
- I tried disabling stealth chop, more noise no solution. Turned it back on.
- I tried disabling TMC_DEBUG (M122) no solution, turned it back on.

I'm at a loss, now, the enabling is set to true fairly randomly, from not starting Z-probing on G28 to completely finishing G29. Somewhere in between it changes Z enabling to true which stops it. And E enabling is set to true (starts at false as it should be at startup) at any random move.

I am considering replacing Z and E with 4988s, just to be done with it. But I think this should work, somehow. I am not the first to use these things, right?

Cheers,

Hugo

Well, that was a boring afternoon. The issue of the extruder is fixed, I fitted a different stepperdriver and now it works. I also think I know the enable issue is not an issue. Marlin keeps enable at false, until you call for the axis (or extruder) to move for the first time. Then enable becomes true and it all works.

The issue now comes down to the homing failing. I made a little gcode printfile and ran it from SD, as I feel the computer communication also burdens the MEGA's processor. The hotend heats up, Z moves, X and Y are homed, and then the Z should start homing but it doesn't. It comes back with "Homing failed" and I need to reset.

I also tried homing all axis individually, moving 10 mm away from each sensor before homing the next axle, but it keeps failing on the Z.

All thoughts are welcome, Iwill now change the topic title if I still can.

[EDIT] I'll start a new thread as this is a new issue that I think is not 2130 related.[/EDIT]

For reinit tmc2130spi after psu return power to tmc you can Insert in top of startup g-code:

;poweron
M80
;M502 - factory reset to enable-steppers
M502
;M501 - Restore Settings to enable steppers
M501

or another way:

M80
M906 ... (from M501)
M569 ... (from M501 if exist)
M913 ... (from M501 if exist)
M914 ... (from M501 if exist)

it solved the problem in my case.

2DEV: For tmc2130spi requires modification code in restore_stepper_drivers. (called from power.cpp and M80_M81.cpp)

Hello, I have a similar problem (I am using just TMC2130 SPI in X and Y axis)
My M122 log is:

 Driver registers:	X = 0x80:0C:00:00
 	Y = 0xFF:FF:FF:FF

And my config_adv is:

  #define TMC_USE_SW_SPI

  #define TMC_SW_MOSI       51
  #define TMC_SW_MISO       50
  #define TMC_SW_SCK        52

I have tried the X axis alone and it gives no error and the motor moves. Then with Y axis and I get exactly the same error . Lastly the Z axis and the extruder alone and they work (even swapping betwen the two drivers that I have).
I have also changed the Y axis CS PIN to some of the free ones but I always get this error.

Any help would be appreciated

The errors on Y are all due to SPI communication not working...

Driver registers: X = 0x80:0C:00:00
Y = 0xFF:FF:FF:FF

FF:FF:FF:FF means it is not talking correctly... so any errors displayed are just nonsense.

pop the Y driver into X and see if it works there. If it does you have a wiring issue on the SPI pins on Y, check all 4 of them
if it doesn't, dead stepper driver (bad soldering or just dead)

"I have also changed the Y axis CS PIN to some of the free ones but I always get this error."
what pins? you can't use d0 or d1 as that is really rx0/tx0

I have tested all drivers on X axis and they work perfectly.

Further investigation has lead me to conclude that the problem is related with MISO pin. If I have all pins connected the board is still on, but once I connect this pin I get the error I mentioned, The same happens if I just connect MISO, I get the same error.

Obviously I have tried with another pins, instead of default D50, but I always get the same error.

Also I have tried it in 3 different boards and I have done the wiring twice, so that´s why I still think it is a Marlin related problem... but honestly I don´t know

Why are you changing the MISO pin ? if its works on X it should work on all of them.

all tmc2130 drivers are connected to the same MOSI, MISO and SCK lines in parallel.
The only thing that is different is each driver chip also has is own cs line

On a ramps the defaults are as follows.
#define X_CS_PIN 53
#define Y_CS_PIN 49
#define Z_CS_PIN 40
#define E0_CS_PIN 42

These you can move around without issues.
