Request: Testing Klipper with Fabrikator Mini V2 / Malyan M100 (STM32F070 or maybe STM32F103)

[3DSTB]

It would be very interesting to verify the possibility to use klipper with these machines. Unfortunitely i can not test it since i don't have such printer. I'm not sure, if it is possible tp flash the firmware via USB or maybe over the SD Card (which is maybe not reversable?).
I already found some informations:

It would be very nice to see a success.

It should be possible to port Klipper to a wide variety of micro-controllers. It's a bit of work to do each port though, so I suspect this wont happen in the short term. If you're comfortable with embedded development, feel free to port the code and submit it.

Cheers,

Hi Kevin,
thank you for your reply. There is another person working with the printer. He is reversing the board layout:
printerBoard.sch.pdf
The original file is here:
https://github.com/goran-mahovlic/stm32Board/blob/master/kicad/printerBoard.sch

I just asked him:
goran-mahovlic/stm32Board#1

The z axis on the printer uses the unipolar stepper driver ULN2003 which works different than a bipolar driver. Is it possible to support unipolar drivers in klipper?
Some code examples for Arduino and a schematic are eg here

Here is a python script for the ULN2003

Interesting. It will require someone with the hardware, development expertise, and desire to do the work necessary to bring it up though.

It doesn't appear there is active development on this, so I'm going to close this for now.

fyi, the 'monoprice mini select' (aka malyan m200) uses the same board, that malyan calls 'mm32'

there is a http://wiki.malyansys.com/doku.php?id=developer_guide_for_mm32_platform

[tablatronix]

Did someone pick this up elsewhere?

[KevinOConnor]

Klipper now has good support for the stm32f103. I suspect the "Malyan M200" would not be difficult to get running with Klipper. However, I don't know of anyone who has attempted it.

if need be , i have a spare motherboard of this type available for someone to try implementing this
