Upgrade the Raspberry Pi (hardware) in the controller?

Hey quesohusker,

@quesohusker

Wow. Thanks. I’m pretty savvy, but even that seems beyond me.

Possibly, but someone that can build onefinity-firmware from the sources can easily achieve it and mount a Raspberry Pi 4 into the Onefinity controller (with modifying front plate to accomodate the swapped Ethernet and USB ports) on a recent Raspberry Pi OS (64-bit) SD card image.

What it looks like is that the original BB controller is pretty much locked into what is there now, and that the future of Onefinity is the Elite series…updating the classic and pro line controllers probably isn’t worth it as I’m sure they will be phasing them out over the next several years.

I don’t think so. First, the buildbotics-derived Onefinity controller has an unbeatable price and it is a complete and capable 4-axis CNC controller.

Second, there is still the original Buildbotics Controller that is under development. It evolved a bit (What’s new in Buildbotics 1.0.2, What’s new in Buildbotics 1.0.0) since Onefinity forked the system and it has now a 15-pin auxiliary I/O port which allows to use external stepper drivers and stepper motors, e.g. closed-loop steppers or servos. See here for details.
