SKR V1.3 - TMC2208 dual z stepper problem. #148

Open bogachansengun opened 4 years ago

bogachansengun commented 4 years ago

I am trying to configure marlin bugfix 2.0.0 ( both from bigtreetech github repo an marlin github repo ).

If I configure like this ;

define X_DRIVER_TYPE TMC2208

define Y_DRIVER_TYPE TMC2208

define Z_DRIVER_TYPE TMC2208

//#define X2_DRIVER_TYPE A4988 //#define Y2_DRIVER_TYPE A4988

define Z2_DRIVER_TYPE TMC2208

//#define Z3_DRIVER_TYPE A4988

define E0_DRIVER_TYPE TMC2208

//#define E1_DRIVER_TYPE TMC2208 //#define E2_DRIVER_TYPE A4988 //#define E3_DRIVER_TYPE A4988 //#define E4_DRIVER_TYPE A4988 //#define E5_DRIVER_TYPE A4988

I have TMC Connection Error for Z2. If I configure like this ;

define X_DRIVER_TYPE TMC2208

define Y_DRIVER_TYPE TMC2208

define Z_DRIVER_TYPE TMC2208

//#define X2_DRIVER_TYPE A4988 //#define Y2_DRIVER_TYPE A4988 //#define Z2_DRIVER_TYPE TMC2208 //#define Z3_DRIVER_TYPE A4988

define E0_DRIVER_TYPE TMC2208

define E1_DRIVER_TYPE TMC2208

//#define E2_DRIVER_TYPE A4988 //#define E3_DRIVER_TYPE A4988 //#define E4_DRIVER_TYPE A4988 //#define E5_DRIVER_TYPE A4988

there is no TMC Connection Error and Z axis motors work but not syncnorised. I tried to adjust with

define DISTINCT_E_FACTORS

define DEFAULT_AXIS_STEPS_PER_UNIT { 80, 80, 400, 93, 400 }

But in this case I got compile error , too many parameters for DEFAULT_AXIS_STEPS_PER_UNIT

Is there a solution for this problem ? or is this a bug for TMC2208 ?

M122 output for two cases are below ;

First of all, the Z2 definition should be correct - using Z2 as E1 sound hacky to me. Have you set Z_DUAL_STEPPER_DRIVERS in the advanced config file? Where does the current settings of 580 come from for x, y and z?

Ofcourse I enabled Z_DUAL_STEPPER_DRIVERS . But does not work. I dont know where 580 come from but I think its default for TMC2208.

fhollermayer commented 4 years ago

I guess you've used the Ender3 example config as a base? That would explain those current values of 580. The second printout (#define E1_DRIVER_TYPE TMC2208 ;) can't be correct - there is a missing entry for E1, are you sure that everything was uploaded to the board as expected?

bogachansengun commented 4 years ago

Yes. You are right. I used Ender3 example file as base. I agree with you , second printout have missing info about E1 . I am sure all uploaded as expected. I think this is a bug of Marlin. I tried with TMC2100 today and result is same. :-( I am thinking about returning back to MKS GEN V1.4 :(

fhollermayer commented 4 years ago

As far as I know TMC2100's have neither SPI not UART capabilities, so what exactly have you tested in this regard? You have removed all debug jumpers (bottom left of the stepper drivers port array), set all UART Jumpers and removed every jumper below the stepper driver, right? Maybe try to switch your Z2 driver with X to make sure that it's not the driver
