Duet3/RRF vs. SKR Pro/Klipper

Interesting..

I was looking at ordering the S6 board, but it is giving an MX or XH Connector choice, but I, nor Googling can seem to work out what the difference is..

Do you mean like different board versions or like different connector types on the board? I think the XH conncectors are those white ones with 2.5mm pitch where you can connect eg. the steppers or the thermistor.

Yeah I think MX is some random connector type. I'll go with XH.

Just gotta press buy now..

Do you prefer Klipper to RRF?

I only encountered two things that Marlin does better in my opinion: configuring the TMC 5160 drivers and controlling ST7920 based (or emulated) display. But you can configure each TMC setting manually in your klipper config file without recompiling and I am currently working on solving the second issue

How did you configure your TMC Drivers btw?

I was thinking about going massively overkill and using TMC5161 as the top spec drivers, in case I decide to do crazy stuff later on.. Wonder if that will cause issues..

I've gone Fysetc S6 with TMC5161s and going to run Klipper and OctoPi with a touch screen.

Here is how I configured my steppers:

Code: Select all

[tmc5160 stepper_x]
cs_pin: PA15
sense_resistor: 0.075
interpolate: True
run_current: 1.1
hold_current: 0.4
spi_software_mosi_pin: PC12
spi_software_miso_pin: PC11
spi_software_sclk_pin: PC10
driver_IHOLDDELAY: 10
driver_TPOWERDOWN: 128
driver_TBL: 1
driver_TOFF: 3
driver_HEND: 2
driver_HSTRT: 4
driver_FD3: 0
driver_TPFD: 0
driver_CHM: 0
driver_VHIGHFS: 0
driver_VHIGHCHM: 0
driver_DISS2G: 0
driver_DISS2VS: 0
driver_PWM_AUTOSCALE: True
driver_PWM_AUTOGRAD: True
driver_PWM_FREQ: 1
driver_FREEWHEEL: 0
driver_PWM_GRAD: 14
driver_PWM_OFS: 36
driver_PWM_REG: 8
driver_PWM_LIM: 12
driver_SGT: 0
driver_SEMIN: 0
driver_SEUP: 0
driver_SEMAX: 0
driver_SEDN: 0
driver_SEIMIN: 0
driver_SFILT: 0

But I honestly have forgotten which microstepping I set. I thinks is 16. But I have no idea

I am really curious how both the board and the stepper drivers will perform. I would go for the stock TMC settings first before trying to set the register contents manually. Maybe your steppers and drivers work better than mine.
