TMC2130 - Marlin 2.0.9.5 - RAMPS 1.4 - Error: All HIGH

Hello:

I'm trying to get my shiny new TMC2130 drivers configured with SPI on my RAMPS 1.4 controller. I'm installing Marlin 2 for the first time with VS code and Platform.io. I've gone through the configuration with single Z-axis. M122 yields this:

Driver registers:

I'm using the default configuration pins for RAMPS 1.4 (pins_RAMPS.h)

  #define X_CS_PIN                            53
  #define Z_CS_PIN                            40
    #define TMC_SW_MOSI                       66
    #define TMC_SW_MISO                       44
    #define TMC_SW_SCK                        64

Any help is appreciated.

You need to add a wiring harness to enable this. Ramps was not deigned for smart stepper drivers, so you need to add wires.

You can usually detect a SPI compatible board if it has the DIAG slots for the extra plugs of any SPI stepper driver. This would usually be an incompatible board:



And this would usually be a compatible board:



Spare yourself the trouble of buying an incompatible board! The wiring is a mess! Buy a compatible SPI stepper driver board to begin with, like the RAMPS 1.4.4 (DIY) or one of those great boards that come with everything on them.

I personally would look at boards from MKS Makerbase. They have a great product selection.

You just need something like this

@Dust if you forget to remove the jumpers underneath the driver modules - which are invisible in your picture above - then the signals will be overwritten to a constant HIGH because of the MS strong signal feeding! Once again, spare yourself the trouble, please.

@The_GTA

You are mistaken. .

Take a closer look at the MS pins on the stepper driver in the above example



The pins only face up! They are not connected to the ramps MS pins.

@Dust: It just shows how complicated your proposed workaround is! I am not mistaken because the user is facing a problem and I just described what the reason for his "All HIGH" message may have meant! It just shows how complicated your proposal is and I don't think that pushing that onto DIY people is a good idea! It is like giving people obviously complicated situations just so they run into problems doing them. If you buy a board that is SPI compatible to begin with there is no funny wiring business. The process is well documented and tested. You cannot plug a wire into the wrong spot (unless you put the thing the wrong way round, in which case you have other serious problems of understanding). You get better cable management. You get better space for installing a cooling fan extension above your printer board. Think about it!

I do have a harness. A photo of my wiring is attached to the original post as TMC2130-SPI.jpg. I made the path of the wires as clear as possible.

@The_GTA: Good suggestion about an SPI enabled board. I may give RAMPS a little more effort as I'm invested in it ATM, but a good option nonetheless. There are no jumpers installed for the drivers.

Did you try this with 12v enabled?
As TMC stepper drivers need this (even to talk over uart or SPI)

And 12v needs to be turned on at the same time or before 5v, not after 5v is active.

@Dust: Thank you! That was key info. I also had to swap a TCM2130 with another channel. Looks like I may have damaged a board.

I now get clean communication, but I cannot get motor motion. I'm enabling with M17 and then G0 X5 Z5 F100. That did it with Marlin 1 & A4988s. Do I need to do something more with my new setup, or do I still have something awry?

disable #define SOFTWARE_DRIVER_ENABLE

These driver use an IO pin

I'm in business.

@Dust: As as followup, I assume that something in the M122 report tipped you off that my SOFTWARE_DRIVER_ENABLE was incorrectly configured. What was it?

Thanks, everyone!

@dlamet

Nope.

I've just seen those symptoms many times before and knew to check if that settings was enabled in the configs.
