Geeetech Delta Rostock mini G2 Operator's manual

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.

4 Most of the code you need to modify is in Configuration.h . More details on this
later.
Find the value you need to compile according to your printer. ( we will elaborate
which part of setting you need to change later one by one). Upon compiling, you can
upload the firmware to your control board. Simply click and to upload.
( Note: You need to disconnect the printer to Repetier Host before uploading).

2 Printer preparing
1. Bed leveling
Put a level meter on the bed when adjusting the 3 screws of the bed to check if it is
level.

Or you can use the such a cube use a reference height about 10mm to make sure that
each top of each bed mounting point is the same after tightening the wing nuts.
Simply place a 10mm cube next to the bed (not under!), and tighten the screw till the
cube rightly fill gap between the bed and the base plate. Take out the cube and repeat
for the other two mounts.

* To protect the bed and the nozzle from crashing, please attach a piece of tape on the
bed.

3 Printer setting
Step1. Connect the USB to your Rostock mini G2 or G2s and power it up. You can
see the LED lights and fan come to life, you may be able to hear the motors idling.
Step 2. Open Repetier Host and ensure that you have a valid port selected for
communications. To do this, simply click “Printer Settings” in the upper right-hand
corner to bring up the printer settings menu.
If you don’t know what the parameters mean, just hover your mouse over the item,
the explanatory note will prompt up. As shown below:

Step 3. Choose the Connection menu to select the COM6 port and the Baud rate
250000. Click OK to continue.

If you can not find the COM port, you can check the device manager to see which
port it is).
If you still cannot find the port, please re -install your USB driver here.
Step4 set the printing speed. And un-check the disable the motors after job/kill.

Step5. Set the number and the offset of the extruders (offset only need for duan
extruder printer),choose the nozzle size and different colors for each.

Step6 Choose printer shape. This is very important. Choose printer type as Rostock
Printer (circular shape) and set the following parameters
Home X: 0
Home Y: 0
Home Z: Max
Printer Radius: 100mm
Printable height: 200mm ( this is the corresponding height in the firmware,
remember to modify this each time after you change the height in the firmware)

Step7. Write the script 1,2,3,4,5
We will use this script as shortcuts later to move the print head to the corresponding
point. For each point, keep the Z as 2.
For G2 or G2pro:
○
1(0, 0, 2) ○ 2(0,50, 2) ○ 3(43.3, -25, 2) ○ 4(-43.3，-25, 2)
For G2s or G2s pro:
○
1(0, 0, 2) ○ 2(0,63, 2）○ 3(43.3，-2, 2) ○ 4(-43.3，-2, 2)
So we can set the following script.

Apart from the above 4 script, we need to add the fifth code to keep the print head
staying in the air and will not creep down the rods.
Script 5:
G0 X0 Y0 Z180
M84 S0
When you click the script icon, the print head will move to the corresponding test
point as shown in the following picture.
Code
G2 or G2pro
G2s or G2s pro
Script1:
G0 X0 Y0 Z2
G0 X0 Y0 Z2
Script2:
G0 X0 Y50 Z2
G0 X0 Y63 Z2
Script3:
G0 X43.3 Y-25 Z2
G0 X43.3 Y-2 Z2
Script4:
G 0 X-43.3 Y-25 Z2
G 0 X-43.3 Y-2 Z2

Write the script 1,2,3,4,5. Here we take the G2 & G2 pro as example.
Script 1: G0 X0 Y0 Z2

Script 2: G0 X0 Y50 Z2
