BIGTREETECH Octopus V1.1 is a very powerful motherboard with 8 stepper driver support, so this motherboard can control up to 8 different axes. This feature is especially suitable for multi-colour 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 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.
