Basic Information:

Printer Model: FL-Sun QQ-S Pro modded for LDM/Clay
MCU / Printerboard: nRF52840/Seeeduino XIAO Sense
klippy.log

Fill out above information and in all cases attach your klippy.log file. Pasting your printer.cfg is not needed

Describe your issue:

There is no Klipper.log file (yet).

I’m trying to use the Seeeduino XIAO Sense as an MCU with Klipper, but I can’t determine which processor to target in make menuconfig. Does anyone know which of the following would be best?

( ) SAMD21G18 (Arduino Zero)
( ) SAMD21E18 (Adafruit Trinket M0)
( ) SAMD21E15
( ) SAMD51G19 (Adafruit ItsyBitsy M4)
( ) SAMD51J19 (Adafruit Metro M4)
( ) SAMD51N19
( ) SAMD51P20 (Adafruit Grand Central)
( ) SAME51J19
( ) SAME54P20

Also, has anyone attempted to use the IMU on this board for resonance shaping?

Hello @willpuckett !

If you have the board: What is printed on the MCU?

I’m not a developer but I’d guess this is not going to work. Each processor, e.g. STMxxx, SAMExxx etc needs to be supported in Klipper so that Klipper know how to deal with this processor.

This board uses a Nordic nRF52840 processor and this is not natively supported in Klipper and I doubt that it is so close to any supported one so that it would run.

@EddyMI3D the pick of the board with the casing removed:

@Sineos the board is a SoC with a Cortex-M4F and a Bluetooth/802.15.4 rolled together. I believe the processor side would be one of the SAMD51 or SAME51 options, but I’m not sure which…

Klipper does not currently support the nRF52840 chips. It is not similar to any supported micro-controller.
