Wondering if support for this chipset can be built? The Anycubic Kobra and Kobra Max both use these chipsets but they seem to be unsupported as of this time. Thanks.

Morning. Scrolling through the comments I couldn’t quite determine. I just purchased an anycubic Kobra this month and would like to get killer running on it. Not really comfortable modding the board. Has anyone got a profile working that doesn’t require modding ? Thanks I’m advance.

Hello again Klipper friends. I’ve managed to get a kind of proof of concept working of Klipper on the stock Anycubic Kobra. This should work for the Max if it has the same issue. It’s going to take a little more to develop, but I would like anyone interested to reply or post here with offers to test…

Hello, i am posting a link to my github repository about the ender 2 pro with the HC32 mcu board. Hope it helps [image] GitHub - ChubbyBunny1/Ender-2-PRO-Klipper-HC32: Klipper firmware for the Ender... Klipper firmware for the Ender 2 pro 3d printer with the HC32F460PETB MCU - GitHub - C…

Cool! Can you provide source code or is it just a build from Steve?

For anyone still interested at this point, HC32F460 support has been merged in to mainline. You just need to provide a config now. I’ve opened a PR at WIP: Support broken TMC boards on the Anycubic Kobra by Jookia · Pull Request #6091 · Klipper3d/klipper · GitHub in hope of getting my fix in mainli…

Hi, by my tests PB1 is the control pin almoust sure . For the sensor pin if I define PB2 debug query_probe returns message “probe: open” (even if its closed) , If I define PB11 returns “probe: trigguered” . the only debug command that works is pin_up and trigguers pin to go up and down. pin_down an…

What board are you using? The actual control pin depends on the board. On mine, assuming the diagram I was looking at was correct, it is PB2. I confirmed it with a multimeter and I think I ran an additional test to confirm that it is PB2 in my board’s case. Either way it looks like a PWM issue both …

I´m using the original creality board on the Ender 2 Pro also with the HC32 mcu as you. On mine if I put PB2 as the control pin and PB1 as sensor pin absolutely nothing happens…

It’s possible that in your case, with PB2 configured as the sensor pin, sending the pin_up command also causes Klipper to check the pin status via the sensor by pulling it up momentarily (if PB2 is configured to require enabling a pull-up resistor on the pin) which could cause the CRTouch to interpr…

Sorry for the topic spam, but I’ve closed the PR and opened this thread: How to support the Anycubic Kobra boards?
