RUMBA32 is a brand new control board from Aus3D! RUMBA32 relies on Marlin 2.0’s 32-bit support, which is rapidly evolving, so documentation and configuration settings may be subject to change.Please make sure you are comfortable following the instructions in our getting started guide before purchasing RUMBA32.
— There is a small fault in the current batch of boards that means the SPI-mode for TMC stepper drivers will not work correctly out of the box.This requires a small mod with a soldering iron for each socket being used with an SPI -mode stepper driver.We can apply this mod on purchase if you plan to use SPI drivers.If you have purchased a board previously, we can provide instructions on the mod or can organise a return to have the modification made.Please see our mos instructions(pdf)or contact us for assistance.—
They’re great-plenty of stepper drivers, heater/fan channels to spare, and they’re built like a tank.Their biggest weakness Like most other printer control boards, they’re 8-bit.Built around the same ATmega2560 that powers RAMPS, there are limits to what they can do and how quickly they can do it.These limits are a function of the CPU speed (16MHz) and the available memory (256K flash, 8K SRAM) of the ATmega2560.These specifications limit how many features you can enable, and how quickly you can run your printer-but now, RUMBA32 is here to erase those limits!
It has been taken the tried and tested hardware design that is RUMBA+ and upgraded it with a new processor:an STM32F446.Boasting a 180MHz clock rate, 512Kb of flash memory, and 128Kb of SRAM, all built on a high-performance ARM architecture.RUMBA32 isn’t just a little bit faster than RUMBA+-it’s an order of magnitude faster.If you’re after a control board that will be set to handle cutting-edge firmware features now and into the future, RUMBA32 has you covered.
We’ll say it again-RUMBA+ is a tank.It’s sturdy and capable, and because firmware support is so mature, it’s always dependable.
RUMBA32 is a 32-bit control board that doesn’t force you to change your whole printer to suit it.Like RUMBA+ and RAMPS, it supports common character and graphical LCDs.RUMBA32 supports standard stepper drivers, like the A4988, DRV8825, and so on, but it also features added SPI driver support:just change the jumpers underneath any driver and you can use SPI-based stepper drivers, like the TMC2130-no extra wiring required! RUMBA32 is a 32-bit control board that runs Marlin 2.0- so if you’re looking for a performance upgrade that will feel comfortable and familiar, RUMBA32 is it.
