BTT TMC5160T
Gday guys,
I just received some BTT TMC5160T. I have never set them up before. I am reading they only work on SPI and not on UART like the tmc2209.
I have bought a Vcore 3 500 combo from RR.
Here's what I came up with x for instance:
[tmc5160 stepper_x]
stealthchop_threshold: 1
run_current: 1.6
[tmc5160 stepper_x]
cs_pin: x_uart_pin
spi_software_mosi_pin: stepper_spi_mosi_pin
spi_software_miso_pin: stepper_spi_miso_pin
spi_software_sclk_pin: stepper_spi_sclk_pin
run_current: 1.6
driver_TBL: 2
driver_TOFF: 3
driver_HEND: 0
driver_HSTRT: 6
I don't have any issue with the x,y,z1,z2,z3 but I can't find any configuration for the extruder in the RATOS config.
Do I need to change physically the jumper from UART to SPI on the octopus board?
Thank you

All of the 5160s have to have all of the jumpers while your 2209s for z or extruder have only the single jumper

Hello @chicken, are you saying the 3x Z's and the extruder can work on UART and the x and y work on SPI?
Yes if the Zs and extruder are using 2209s. That is typical what most people do. There is no advantage of running 5160s on those. I think there are even some disadvantages but don’t know off the top of my head. My VC3 and VC4 are configured with both sets of drivers like that.
I have 6x 5160T so I may as well use all of them
Oh right, so, only x and y on SPI (5160) and the rest can stay on 2209
Interesting
Thank you, I am going to test that now !
Yah leave the z and extruder on 2209: good luck
Everything works that way ! THanks @chicken - Now onto calibration ! Cheers mate
your welcome!
what printer are you building?
the build is a Vcore 3 500 package from RR
