Zyrus Etcher Bill of Materials

------------------------------------------------------------------------------------------------------------------------------------------------------

Electronics:

Printed Circuit Board: See "Zyrus_Etcher_Board_MK2.1.zip" and upload to a service such as JLCPCB for manufacturing. Should cost around $30. Note this is the most current version, but does require a couple 'bodge wires'. I plan to update this board to not require bodge wires; this will have a different version number.

Note: Typically the stepper drivers come in packs, but any TMC2208/2209 RAMPS compatable driver will work. Using the TMC2208/2209 drivers for their 256 microstepping along with their high efficency (no cooling fan required). UART communication is not used.
