Next Steps

Phase 1: Stepper Motors

Do full wiring diagram for Arduino with RAMPS with TB880 stepper drivers
Assume 4 motors driving each axis at 1A each and 24V - are the stepper motors in D3D BOM good for 24V?
Use USB power for Arduino
Do not plug in the power to RAMPS - can it be powered only by the USB power via Arduino?
Connect the TB880 with up to 4 stepper drivers each
Use 24v power supply for stepper motors - can the usual steppers handle 24V?

Phase 2: Resistive or other Loads via External Relay

Use AC heater pad so the bed heater is not relying on a DC power supply. This can be done with an external relay activated by the normal RAMPS heat bed output - [1]
Heater pad - [2] - but any load can be used for testing the relay heat power, such as a light bulb or electric heater.

Phase 1:

Phase 2:

Use Lulzbot Cura
Use RAMPS + external TB660
Connect 4 motors to one TB660
Run them with cura
That's it - if we can run 4 steppers with Cura, RAMPS, and 1 TB660 - we can then drive a CNC Torch Table.
