Geeetech Rostock mini G2 & G2s pro Quick Starter Manual

Please

DO NOT

rush to start your first printing after assembly, as this is a DIY kit,

some parameters of the printer may be different from each other, you need to modify

the firmware according the the real situation of your printer.

You are advised to read through the whole set-up instructions step by step to get a

whole picture of what you will be doing and stick to our instructions before you start

with your printer. Do not skip any details.

1 How to modify and upload firmware.

In the following set-up process, you will need to modify and upload the firmware by

yourself, so, first of all, let’s start with the firmware compiling and uploading process.

1. Download the firmware here:

Firmware for Delta Rostock mini G2 &G2s pro

2. Connect GT2560 to your PC with a USB cable

install FTDI drive. Usually it will

install automatically. If not you need to install manually.

download the FTDI driver

here

.

3. If there is nothing wrong with the hardware of board, you can find COM port in

device manager. But every computer has different COM watchword, you need check

by yourself.

4. Unzip the firmware, drag all the files into Arduino IDE.

I use Arduino1.0.5)

choose

Board\Arduino Mega or Mega2560

and selects

ATmega2560(Mega2560)

as

default Processor. The order cannot be wrong. Selects the COM port you find in the

device manager.
