Marlin tutorial for installation BTT EXP-MOT V1.0 with TMC2209?
Hi! im trying connect btt exp mot with tmc2209 for a 2 x carriage but give me a error, need a tx and rx pin? please have any tutorial? thanks
Do you see on the bottom of the boards, you have pinout marked and on exp-mot look for Exp-mot | M1RX<->1.21 | SKR 1.4 | M2RX<->1.19 | | M3RX<->0.28 |
Its talking... but when i try to move motors they just buzz and nothing else. if anyone has idea what that is about. oh stepper drivers are ok I tried them on skr board and stepper motor also works
oh and pins txt so you can se what is diferent

the same problem here, maybe a conflict with LCD or SD support?? Just Motor2 working properly, motor1 buzzing and motor3 not working
Hi JJare, i have the same problem and find a workaround for me. In the file src/HAL/LPC1768/spi_pins.h
original: /** onboard SD card / //#define SCK_PIN P0_07 //#define MISO_PIN P0_08 //#define MOSI_PIN P0_09 //#define SS_PIN P0_06 /* external */ #ifndef SCK_PIN #define SCK_PIN P0_15 #endif #ifndef MISO_PIN #define MISO_PIN P0_17 #endif #ifndef MOSI_PIN #define MOSI_PIN P0_18 #endif #ifndef SS_PIN #define SS_PIN P1_23 #endif #if !defined(SDSS) || SDSS == P_NC // gets defaulted in pins.h #undef SDSS #define SDSS SS_PIN #endif
my version: /** onboard SD card / #define SCK_PIN P0_07 #define MISO_PIN P0_08 #define MOSI_PIN P0_09 #define SS_PIN P0_06 /* external */ #ifndef SCK_PIN #define SCK_PIN P0_15 #endif #ifndef MISO_PIN #define MISO_PIN P0_17 #endif #ifndef MOSI_PIN #define MOSI_PIN P0_18 #endif #ifndef SS_PIN #define SS_PIN P1_23 #endif #if !defined(SDSS) || SDSS == P_NC // gets defaulted in pins.h #undef SDSS #define SDSS SS_PIN #endif
If the MOSI_PIN is not previously defined, then the compiler take in the original code the MOSI_PIN from P0_18 (on the EXP-MOT there is first motor step pin) and the MISO_PIN is used from P0_17 that is used from the third motor on the EXP-MOT Board., and the second motor is running normal.
I hope this will help you.

o mesmo problema aqui, talvez um conflito com suporte a LCD ou SD?? Apenas Motor2 funcionando corretamente, motor1 zumbido e motor3 não funcionando
I'm with a similar problem I put the Z2 in the E1 but when I trigger the engine it is buzzing (signal that this with high amperage) only I below the amperage and continues buzzing, I tried to do by marlin, in TFT, in trimport but to no avail. if I find out anything I share

I hit the same issue and although the above didn't fix it for me it did lead me down the right path, in configuration_adv.h I had SDCARD_CONNECTION connection set to LCD not sure if this is default, but that was causing my extra steppers to not move, so simply setting it to be "#define SDCARD_CONNECTION ONBOARD" then corrected the issue. and if you are interested where the values are being set it's within the Marlin\src\pins\lpc1768\pins_BTT_SKR_common.h line 131 ish. essentially setting it to be the same as Gruenbacher, but in a cleaner way that avoids conflicts when building (which I had)
hopefully that additional info is useful :)
I got this fully working for my setup now, https://github.com/sjporte93/BTT_skr1.4Turbo_BttMotorExpansion if anyone is interested, it does have quite a few custom things set, hopefully all should be explained in the readme.
also reading up, the buzzing motors is usually a sign of off wiring? are you swapping wires when you test it on another axis and it works? I would try swapping the two middle pins motor side on the connector, if you still have that issue.
I did this setup but I'm having a little problem. the application would be to use the M1 for Z2 M2 to Z3 the M1 is working properly but the M2 does not work the engine is as if it were with the wires reversed (that is not the case)
I've tested everything and just missing a detail that I imagine may be the problem.
what value did you put in config.h in Serial port 1 and serial port 2?
