1,Install and connect
1)need software as follows:
A: repetier, it’s the PC software to control the printer, slice and print the
Model
B: arduino, it’s the working environment of the firmware(marlin)
C: marlin, it’s the firmware, you need flash it to motherboard when you
Reset the height of the machine
D: others, you would need the other file like drivers, streamline etc,
When your PC cant recognize the board through USB
2)Connect the kossel mini USB port(arduino mega 2560), in device
Device manager, verify the COM port number assigned for the arduino
Mega 2560(eg.com15) as follow shown

If your PC could not connect the motherboard, need a step to install the
driver:
Unzip the “driver” in the software file, and install the file”dpinst-amd64”
if your PC is 64 bit; or install the file”dpinst-x86”if your PC is 32 bit, all in
all, ensure you could find the “arduino mega 2560” port in the device
manager
3)install “repetier” in your PC, the software of “repetier” has been
packaged in the SD card, you could install from there or download from
the internet(https://www.repetier.com/)
4)the other software of marlin and arduino only be used when you reset
the height of the machine, so it is need not for the first print
5)The height of the machine has be set already when it is out off the
factory, the highest position is decided by the limit switch block, we have
determine it’s exact position by the board fix item like the pic1, and the
lowest position is decided by the USB interface like the pic2, finally the
print height of the machine is determined by the two position, it is
285mm from the highest to the lowest

If you want DIY your printer’s height by yourself, you could change the
limit switch block’s position to rise or reduce it’s height, and you have to
reset the height’s value in the marlin, you could refer to the chapter 5

2,level the bed and auto-leveling
(1)test the function of repetier
1): install the repetier in your PC;
2): run repetier
language

Connect
Communication Port

3): printer settings
printer type:rostock printer(circular print hap)

Home X min; hone Y min; home Z max
4):home function
CODE: G28 or GUI:
Easy mode then input g28 and send

Then the three axis’s pulley will go up to the top until hit the switch
5)Control panel

6)Extrude and reverse
Type m302 before use this function

7)Move nozzle at x y and z axis

8)Preheat hotend
Control panel: adjust from there
Check from there(bottom of repetier)
Temperature curve

9)Info of operation
Check at the bottom

10)Info of coordination
MCODE: type m114 then check at the bottom
11)Info of limit switch
MCODE: type m119 then check at the bottom
Observation: x_max, y_max, z_max, z_min
Hit the switch= triggered
Not hit switch= open

(2)level the bed
1): input g1 z0 : the nozzle will goes down to the position which is very
close to bottom plate
2) adjust the springs to ensure the plate is leveled at three coordination
A: g1 x0 y-60 z0;
B: g1 x50 y30 z0;
C: g1 x-50 y30 z0;

A point:
adjust the screw, ensure the bed nearly touch the nozzle( there should
be a gap of a paper between the nozzle and the bed)

The same method at B and C points then the bed would be leveled
enough
(3)Auto-leveling
1) home the nozzle
