Best all around board

I got this as a gift and used this in my Zero G mercury 1 build, and it is outstanding. Love the flexibility for 48volt steppers, 8 steppers, and all sorts of sensors over usb or CAN.

does the job

using in my trident. no issues so far. easy setup for my first build

Great controller

Love the Octopus Pro. Flexibility to shift into 48V at a later time. Unit has been rock solid for over 1600 hours of printing.


This is one sweet board, so sweet we carry two versions of it. The Octopus Pro has been boosted to 60V! Perfect for an all out, or future proof build.

The key difference between the 446 and the 429 variant is the 429 has an upgraded board (SMT32F429ZGT6) with 1M memory vs 512K with the 446.
