BIGTREETECH Octopus, V1.1

BIGTREETECH Octopus is a very powerful motherboard with 8 stepper driver ports, so this motherboard can control up to 8 different axes. This feature is especially suitable for multicoloured printing and tool changers, for the use of different tools / modules such as different 3D print heads, laser engraving, laser cutting etc. All fantasies and ideas of modifications can be realised.

The mainboard is compatible with Klipper, Raspberry and Marlin open-source software.

180 Mhz ARM-Cortex-M4 CPU

BIGTREETECH Octopus V1.1 uses a 32-bit chip from the ARM Cortex-M4 series STM32F446ZET6 with a core frequency of 180 MHz, which offers enough power to realise even the most demanding applications and ideas.
