介紹
A compact all-in-one controller board for RepRaps with one extruder head, optimized for mass production.
The point of RepRap is to make itself, of course. But sometimes people just want plug-and-play RepRap electronics so they can concentrate on the other aspects of the machine, or just because they are more software or mechanics oriented than electronics oriented.
Melzi is designed to be a complete set of RepRap electronics that should be very cheap to mass produce. It was originally based on the Arduino Leonardo and is named after Francesco Melzi, who was Leonardo da Vinci's pupil.

Melzi Version 1.0 (Ardentissimo)
The Melzi V1 used a ATMEGA 644P microcontroller, and 4 x A4988 stepper drivers. However, problems with the routing of the fine tracks on the PCB quickly became apparent, which made them hard to make reliably. Often thermistor readings are inaccurate, or fail.
BEWARE! Some cheap online sellers still sell this version of the Melzi! See 'How to get it' list lower down this page.
Melzi 1.0/2.0 eBay Hybrid
Most listings online for "Melzi 2.0 1284P" or "Melzi V03" (as above) actually use the 1.0 board schematic, including "Melzi Ardentissimo" lettering and A4988 steppers like the 1.0, but use an ATMEGA 1284P microcontroller like the 2.0. Firmware for the 2.0 will work on these hybrids.
