Hi mate. Is it possible to get field weakening in your firmware?

PMSM firmware not reimplemented, separate controller for that and a bit difficult to flash since controller has to be taken out of the aluminum housing and potting from bottom of PCB has to be removed.

I did some investigations and was able to compile/flash/run code on the motor control MCU. Wrote an Arduino based programmer to flash the other MCU: https://github.com/danielnilsson9/78k0r-pgm

So in theory we have everything that is needed to reimplement an open source version of the motor control firmware but none exist at the moment and it is not something I am working on either...

There are some caps on the board rated for 63V so 72V not an option without replacing those at least.
