32 bit controller under 100$ and marlin

Is there any 3D printer controller which is 32 bit and have extrenal stepper drivers (support TMC2208) and support marlin and multi colors printing?

RADDS + Marlin4Due might work, but i have no personal experience with this combo.
There is also a brandnew Ramps board in the pipeline, which should work with 8bit and 32bit controllers.
Don't know if it launched already.

... I'm using RADDS with ArduinoDue (Marlin4Due firmware) and RAPS128 stepper drivers for my private machines -- and an "industrial" variant (+24V I/O-pins with optocouplers and 0-5V/0-10V analogue voltage levels) on the comercial machines ... but it's more than 100$ ...

What is that board called? is it a Linux CNC with a MESA card? If not, does the 0-10V mean that it supports torque/speed control servos?

... it's "our own" CNC-controller, called GT1002 and composed from an ArduinoDue-shield (which uplevels the 3,3V to 5V with optocouplers and the DACs from 0-3,3V to adjustable analogue outputs with up to 0-10V) and a BOB with 24V signal level and 4 sockets for dropin- or connectors for external stepper drivers:




It's either integrated in our machines or available as separate box - [gie-tec.de]

Why do you insist on Marlin, when RepRapFirmware offers so much more on 32-bit boards?

RuRAMPS4D is IMO the best low-cost option: [reprap.org]

I'd vote duet Maestro - its' basically a duet wifi but cheaper. It supports everything you want except marlin. Im going to guess you want marlin because thats what you're used to? But RRF is much better on 32 bit controllers and I personally thing its much easier to setup and use.

I think the Maestro is actually going to slightly break your budget but in the long run will probably be cheaper because you wont need octoprint / raspberry pi as well

Meh, the price is close enough now i just bought a Duet Ethernet.

You just have to decide, can I trade off a few rolls of future filament for a nice 32 bit controller?

I don't want a forced sub $100 32 bit board, let it happen naturally.

What are we talking here, it's $150 US if you buy straight from Duet. I paid a little more from a local reseller.

Life is too short, how long are you going to wait to save $50 bucks? It could cost $50 in shipping alone if you to buy a board and had to get steppers from separate locations depending where you live.
