Klipper on Duet 3 Mainboard

Luke'sLaboratory

I might have not explained correctly, There's an External Clocking Crystal on PB22/PB23 per the schematic (which was released after I started this project) - The build that I was flashing+using on the Mini5+ didn't set up the clock using an external crystal (or is it just called a clock?) instead using the internal clock. They have requested that I use the external crystal that's baked into the board as they believe it will aid in multi-mcu sync with better clock predictions.

I think they're going for "if its there, use it"

Good evening.

I am trying to run klipper on Duet 3 6HC.

Why, after applying the changes recommended by this link https://github.com/KevinOConnor/klipper/pull/4133/commits/0d5c6d3c029e68875c4adfe3cdc18913ec71bed8, after command make menuconfig, klipper gives an error, here is a photo of the error.

Thank you very much!

Hi - my PR is only for the Mini5+. it doesn't work at all on the 6hc yet.

@luke-slaboratory Hi, did anyone get around to getting the Duet 3 6HC board to work with Klipper successfully?? Ive been searching since last night on how to get this working just to try it out ... but no luck. Thanks.,

@rockydubb

I have two 6hc's on my desk right now in various states of klipper-ification. We're currently trying to figure out something spooky in the clock code - it initializes serial comms on UART1 correctly, but something goes haywire immediately after and it freaks out and stops talking.

Sorry, but we are working on it.

@luke-slaboratory Wow, okay great to hear you guys are working on it. Thanks for letting me know! I'll be looking forward to trying it out once its ready. Thanks for the update!

slaz

@luke-slaboratory Is there any chance that you got further on this? Would appreciate it lots. Thanks lots in advance for all the work you do

@slaz

I'm finally back up-and-runnning after moving my family across our state and getting started with a new job.

Progress was essentially paused until a little bit ago.

Sorry for the continued delay, life be busy

slaz

@luke-slaboratory First of all congrats on the new job hope it's something you like. No need to be sorry, family and personal things come first I can thank you for the work you do and can say lots of people appreciate it and we are glad that you work on this. Thanks for the update and will stand by and looking forward Stay safe

slaz

Hi @Luke-sLaboratory, me again bothering you. Sorry for it. Just wanted to ask if there is any more progress on this one? Can't wait for it. Thanks lots in advance

Luke'sLaboratory

@slaz

Needs a massive re-do, but it talks. Needs USB driver next.

slaz

Nice nice. That is amazing. Thank you lots for the update. You are doing so great. I will go back in my shell and keep waiting and hoping Much appreciated by the way

@luke-slaboratory This looks great! Kudos!
I just received my duet 3 board and wanting to run klipper on it..
Are there any news? Are you planing to contribute it back when done? (Like to offical klipper repo)

Also, if u need help with testing / porting i have some experience with other projects / code, maybe i can help out

@dxcx

There are people far smarter than me working on it right now - they'll be officially adding it when its ready.

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

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!
