Next Steps

Phase 1: Stepper Motors

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

Phase 2: Resistive or other Loads via External Relay

  1. 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]
  2. Heater pad - [2] - but any load can be used for testing the relay heat power, such as a light bulb or electric heater.

Prototype Cost

Phase 1:

  • RAMPS - $5.82 [3]
  • Arduino - $12 - Not CH340 bootloader
  • TB660 - $8
  • Power Supply - 24V - $21 - [4]
  • Stepper motors - $8 each for a pack of 5

Phase 2:

  • Relay - $8
  • Heater pad - $20 for 1000W, or DIY via nichrome wire.

Test

  • 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.
