Hi,
i readed everywhere that both version of the Octopus Pro v1.0 support Klipper :
F446 @180 MHz/512kb – support Klipper
F429 @168 MHz/1Mb – support Klipper + RRF
Considering the small difference in price i’m considering to take the F429 which seems to be more versatile but:
Are there possibile issue / more complex procedure to configure Klipper on F429 respect to F446?
F429 has a lower frequency, is that worse for Klipper or has no influence at all considering that there’s a Pi4?
For last i see on the BIQU page another (new?) version H723 (STM32H723ZE) with 550 MHz/512kb which is reported as “Best choice for Klipper with high speed printing, etc”
The SKR3/3 EZ will be the fastest for Klipper; there is an update in the works to take advantage of a feature in the STM32H743 that will make it the current BTT Klipper speed champion.

Thank you, i see SKR3 EZ, talking about the MCU that board has the same of the Octopus Pro i mentioned before so i figure that Octopus will be at the same level in terms of speed capability but, again, the point is that i don’t understand if i can use an SKR3EZ or an Octopus Pro with this MCU now “out of the box” using the same published procedute for the F446 OR instead is not yet usable and i need to wait some further implementation or i need more complex procedure to make it work.
I would like to take a good board but i don’t want additional configuration problem respect to what i have to do with a F446.
About the SKR3 has not the same number of driver and I/O so what’re the other improvement? maybe the EZ driver? About them i think that are cool but external TMC5160 HV from Mellow will be better considering the big capacitors, mosfet,better cooling etc, i’m wrong?
Sorry, i was editing my previous reply while you responded…Ok so, also Octopus Pro support HV drivers TMC5160 Pro as SKR EZ do. HV drivers are not supported only on Octopus V1.
Octopus Pro has also more I/O than SKR, i’m not able to use 1 SKR EZ for a Voron so need 2 board…i caan do it? may be but, what’s the advantage?
I never considered to buy an SKR EZ, i’m trying to follow your tips but i’m still not understand the benefits of using (at this point 2 board) SKR EZ over an Octopus Pro, and i still not understanding the solution to the problem i asked for =D.
With respect to processing speed, all of those chips are “insanely fast”. You shouldn’t have any realistic speed limitations with any of them. I’d choose the board based on the hardware features that you want (eg, number of stepper drivers, number of fans, voltage range, etc.).
Hi
I fiddled around a bit
It works for me with this setting
[*] Enable extra low-level configuration options
Micro-controller Architecture = STMicroelectronics STM32
Processor model = STM32H723
Clock Reference = 25 MHz crystal
Bootloader offset = 128 kib bootloader
Communication interface = USB to CAN Bus bridge ( USB on PA11/PA12)
CAN Bus Interface ( Can bus ( PD0/PD1))
CAN bus speed = 500000
