Thanks for the input.
I was interrupted by a flue but now the is MCU developement board sent for manufacturing. I opted for the cheap shipping so we will see when it arrives.
Heres som draft specs of what I have in mind:
ARM mcu(ATSAM3S2A)
USB
4 stepper motor drivers, XYZE (A988)
3 endstop inputs, XYZ
1 PWM extruder heater driver
1 Fan control output
1 driver for external FET(bed)
2 temperature monitor inputs(thermistors)
20V max supply voltage
Emergency stop
Software controlled motor current setting(digipot)
Unused pins on headers
Have I forgotten anything?
Do you think it would be a good idea to have an on board serial flash as file storage?
