Review on KeeYees Professional Printer CNC Tutorial by Marco Hubbard

Revainrating 3 out of 5

Bent pins, broken USB connector

Really bad quality boxes. The pins are bent on both boards. The USB cable gets stuck in the board and cannot come out without the help of a screwdriver. Only 32kb doesn't fit on an atmega328P-U so I'm tossing it in a drawer while I wait for another project.

Pros
  • ★ Stable Performance ★ The A4988 driver chip has low power consumption and does not get too hot during operation. The performance is more stable than DRV8825 chip.
Cons
  • Crumpled packaging
