Add support to ET4000+ (AT32F403 mpu)

[dinosauria123]

I try to run Kalico on EasyThreed k7 (ET4000+ board with AT32F403 mpu).

I did some workaround (select 20K bootloader) and I could run kalico and the printer was connected to moonlaker.

However, I can't move any axis ( motor didn't running).... It is the same as I choose STM32F103 on Klipper.

Any helps appreciated.

Kalico seems to work on EasyThreed k7 (AT32F403 MPU).

You need to edit kconfig to enable 20kB bootloder. printer.cfg almost the same for MKS Robin Lite except rotation distance.

The problem is EasyThreed K7 doesn't have x-y axis limit switches, it is difficult to homing (xy=0) setting.

I would like to add x-y limit switch. My printer.cfg is attached.

Homing override is needed when you use without xy limit seitches.
