With some help from my friend Harold I have now stripped down the ROBO to it’s bare essence. Gone are the Arduino and RAMPS board, the power supply, and the rat’s nest of cable tied wires underneath. All the wires are now brought to the top where they will go up to the location of the circuit board. I’ll make a custom circuit board complete with simple, elegant, and powerful circuits like a linear power supply and the custom stepper and heater controllers all based on the humble and affordable ATtiny85 8-pin processor (with Arduino programming). At this point I’m interested in running the wires to the top where breadboarded circuits will drive the system. Oh, video on this is here: https://www.youtube.com/watch?v=EjHkdPAdm2Y.
Harold says “It’ll never work again”, half joking and half serious – I say otherwise. What do you think?
