I wasn't able to find any reference to this project here, but wanted to ask if anyone has tried it, or if not looked at it and decided not to try it.

On our machines, this software would move the dynamic motion calculations from the Rambo to the Raspberry Pi (Octopi). The software on the Octopi would process the G-Code, produce accelration, deceleration, smooth direction changes via look-ahead processing and so forth. It would do a better job at this than the Rambo becuase of the greater processing power in the Octopi and presumably (?) because of more sophisticated mathematics and architecture.

The firmware on the Rambo is flashed to a form which seems likely to be pretty dumb, basically it does the movements without any processing itself.

The advantages of this setup are listed on O'Conner's github site.

I have twelve other projects underway and won't be able to get to this probably until February, but wondered if anyone else had looked at it.

I'm looking at this as well. there is also a Pi hat available with SMC2130 drivers on it.

looks like an interesting option for upgrading the stock hardware
