Klipper on Duet 3 Mainboard

flopo76

Hello,i flashed my duet 3 mini,for a Voron 2.4,but klipper not recognized uart adress for the driver 5 and 6 with !1 and !2 Work only first 3 driver uart_pin 1...2..and 3. Other drivers with !1 not recognized.

Pins for reference:

Driver Step Pins - 0:PC26, 1:PC25, 2:PC24, 3:PC19, 4:PC16, 5:PC30, 6:PC18

Driver Dir pins - 0:PB3, 1:PB29, 2:PB28, 3:PD20, 4:PD21, 5:PB0, 6:PA27

Driver Enable - !PC28

Uart addresses - 0:0 1:1 2:2 3:3 4:!0 5:!1 6:!2 | "!" is for inverted select pin

Thermistor Pins - T0:PC0, T1:PC1, T2:PC2

Vssa Sense:PB4 | Vref Sense:PB5

Current Sense resistor for drivers - .076ohm

SPI lines:{PD11, PC7} -> Shared SerCom#7, SPIMosi:PC12, SPIMiso:PC15, SPISCLK:PC13

Vin Monitor:PC3, uses 11:1 voltage divider

LED's - Diag:PA31, Act:PA30

12864 LCD - LCDCSPIN:PC6, ENCA:PC11, ENCB:PD1, ENCSW:PB9, LCD A0:PA2, LCDBeep:PA9, LCD Neopixel Out:PB12 (shared with IO3.out)

Neopixel Out - PA8

Serial0 - TX:PB25, RX:PB24 (USB)

Serial1 - TX:PB31, RX:PB30

SBC SPISS pin:PA6, SBCTfrReady:PA3, SerComPins:{PA4, PA5, PA6, PA7}

CAN Pins - TX:PB14 RX:PB15

Heaters, Fan outputs - {Out0:PB17 Out1:PC10 Out2:PB13 Out3:PB11 Out4:PA11, Out5:PB2, Out6:PB1} | Out6 is shared with VFD_Out

GPIO_out - {IO1:PB31 IO2:PD9 IO3:PB12 IO4:PD10} IO4 is shared with PSON

GPIO_in - {IO1:PB30 IO2:PD8 IO3:PB7 IO4:PC5 IO5:PC4 IO6:PC31}

Driver Diag - {D0:PA10, D1:PB8, D2:PA22, D3:PA23, D4:PC21, D5:PB10, D6:PA27}

Mux Pin - PD0

EXP headers only support 12864 LCD's

@flopo76 you need to invert the "select" pin, not the address pins -

flopo76

In this way?

[stepper_x]
#driver6 X in MOTOR B
step_pin: PC18
dir_pin: !PA27
enable_pin: !PC28
microsteps: 16
rotation_distance: 40
endstop_pin: ^PC31
position_endstop: 0
position_max: 450

[tmc2209 stepper_x]
uart_pin: PA1
tx_pin: PA0
select_pins: !PD0
uart_address: 2
run_current: 1
sense_resistor: 0.076

@luke-slaboratory is there a fork somewhere to participate in that development / testing?

@Luke-sLaboratory Hi Luke, did you manage to get Klipper working on the Duet 3 6HC board? Thanks!

@rockydubb

Just merged. Configs to come "soon"

eamaclean opened this pull request in Klipper3d/klipper

closed Add SAM E70 support #5366

@luke-slaboratory That's great news. Do you know if Duet Tool Board support will be included as well?

@dhusolo klipper doesn't support CAN-FD so I doubt it

For future travelers, I was one of the folks testing Alex Maclean's work. I haven't used the latest (time) but wanted to share my config as an example. Note it might have bugs, but hopefully gets you started: https://github.com/ibash/railcore-klipper/blob/main/ibash.cfg

The Klipper config is much more readable and user friendly than the RRF config. Just saying.

if you dare disagree with them they become an abusive angry mob

That's not different from many other aspects of our lives these days.

@arnold_r_clark well said, even though I'm coming into this thread a few years later. I actually paid someone on Youtube to do some videos about Klipper when it was first coming out. But it was hard for them to make a video back then, and klipper was in it's infancy.

Anyways, if you read this, I appreciate your honesty and intelligence.
