6 some important command
Controling the printer by repetier,after opening repetier,choose right port and click connect. The
repetier interface is like this
open “command bar”where we can input command.Click Easy Mode open command bar，can
input command in command bar.
Then click Toggle Log,The information bar appears below the repetier interface.can read info
about printer in information bar.
(1) g28----all axis go home
In the repetier letters are case-insensitive,G28 also can be used.but in simplify3D,only can use
capital letters .The other command is the same
Send g28,in delta 3D printer all axis rise and hit limit switch ,then stop at the highest position.
G28 is same to this icon
(2) m114----check the current coordinates of the nozzle
input m114 and send ,can see the current coordinates of the nozzle in information bar.
This coordinate is the coordinates of the nozzle after the home,z axis coordinate varies according
to the maximum height set by each person
(3) g1 x_ y_ z_----move nozzle to targeted coordinate
For example ,input g1 x20 y20 z20,the nozzle will go to coordinate x y z(20 20 20)
After we send this command ,we can view coordinate of nozzle now.
It’s ok to move only one or two axis
Eg:
g1 z0—x and y keep previous coordinate,z coordinate arrive to x 0,this arrive the lowest bottom;
g1 x20—y and z keep previous coordinate,x coordinate will arrive to x 20;
g1 x20 y10—z keeps previous coordinate,x coordinate arrive to x 20;y coordinate arrive to y 10;
g1 y15 z30—x keeps previous coordinate,y coordinate arrive to y15; z coordinate arrive to y 30.
(4) M119----check the status of the switch.
The switch status is important directive,when meeting the motor moving problem,can check the
switch status to search problem.
When hit the switch,it shows TRIGGERED;if not touch, it shows open.
When send g28,the nozzle will go home,then send m119
It show:
x_max TRIGGERED
y_max TRIGGERED
z_max TRIGGERED.
Z_min open ( this is autoleveling switch )
If the nozzle is at the middle air,not hit any limit switch,all four switch show open.
It show:
x_max open
y_max open
z_max open
Z_min open ( this is autoleveling switch )
(5) m302----manual control extruder motor
Before manual control extruder motor ,need heat nozzle to targeted temperature and can melt
filament.this step is to prevent the extruder run at cold status, then input 302.
Important note:if use M302 code, must guarantee the nozzle temp reaach 175℃。
If can not reach 175℃，the extruder can not run. !!!
When heating the nozzle ,first input m302 and send ,and then click extrude,we can see extrude
motor run ,and filament come out from nozzle(if you have installed filament)
(6) g29----Auto leveling command
g29 is to control auto-leveling,input g29 and send ,the nozzle go down and touch bed with dozens
of points.then can print directly(after using g29 don’t use other command).
2 Leveling and printing
1 the max printing height
The max printing height is one important data,when assembly printer, we provide two key
points, if do as we design,the max height will be 315mm, even have small error,fine tune can help
solve.
When out of factory,we have flashed firmware to board,the max printing height is 315mm.if the
limit block and plate is not assembly as we design, need set the new max height, in later
chapter,include guide how to set up the max height and flash firmware.
2 two important key points
1 first key point
The distance between aluminum top and limit block is 45mm,the turbo fan can help you confirm the
distance.
2 second key point
The M3*20 screw to fixed the platform must arrive to the lowest bottom and fixed to the tightest.
if the key points are not done as this,the max height will not be 315mm, the nozzle maybe hit
the platform first,and you also need confirm the max height and change max heigt in firmware,then
flash to board.
3,Auto-leveling
1,check the tightness of the screws; it determines the sensitivity of automatic leveling.
To A,the m3*20 screw can not fixed to the bottom,can press the switch is ok.to B,the spring can not
too loose or too tight,the nozzle should bounce up smoothly,these two points can be adjust in any
time.
2,send g28,help the nozzle go home.
3,send g29 and the nozzle will goes down and touch the plate by 36 points.
4,when printing,if the first layer can not stick on the platform well,we advice you adjust the three
screws on the platform, to make small adjust,can help you get a good effect. The auto-leveling and
adjust the three screws can work together when printing.
4,Start printing
Important Note
A,when use switch power supply,If your country AC voltage is 220V,pls choose 220V;if
it’s110V,pls choose 110V,there is one adjust button on the switch power supply.
B, when heating the nozzle or printing,for the fan which cooling heat sink,guarantee it
working,if not,pls stop heat and print.
C,when first printing or when you are not familiar to the printer.we recommend you not
set Reverse filament,to avoid the nozzle block. And when you are familiar to the printer
and understand it well, you could make the advanced settings.
D,we recommend you use the software “Repetier”when printing,it’s intelligent and
efficient.
E,the temperature is a important parameter, for PLA filament, the working
temperature is 200℃-210℃, you could adjust it,and the temperature should not too
high.too high temperature maybe lead to Nozzle clogging.
1 Feeder filament
Before printing,connect USB and power supply,then feeder filament.
2 Slice
The 3d printer only can Identify g-code files,so need slice first,transfer the stl file to g-code file.
3 slice setting
when first printing or when you are not Familiar to the printer.we recommend you not set Reverse
filament,to avoid the nozzle block.All these stting for 0,it mean not reverse filament when printing.
When you are familiar to the printing work,could add to set the reverse.
The above pictures only show some key parameters setting when slice, about more info about the
slic3d software,pls go to the link as follow.
http://manual.slic3r.org/intro/overview
4 printing
Complete sliced,could start printing,click the “Start print”,will print the model, the panel display
printing progress.
3 Marlin and max height
1 Arduino
The marlin is the printer program which run the printer,it’s also named firmware.
Arduino is an working environment for firmware, only installing the arduino on PC,then can
open marlin and flash program to board, if you are not familiar with the software,pls don’t change
any parameters,thank you.
2 Marlin
1 Open marlin
open marlin, if it’s compressed file,must unzip it.
find the icon green color,this format is “ino”, click and open it in arduino.
2 settings
Firmware could only be upload succeed when the settings like the above
Go to tools > board >arduino mega 2560
Go to tools > port, select the COM port
Go to tools > programmers > USBtinyISP
3 Upload Firmware
Click the 上传（Upload）button to upload the Marlin Firmware Sketch to Kossel Mini Controller
Board. Once upload successful, message “Done”.
pls disconnect repetier when flash firmaware !!!
3 confirm the max Height
The max height is so important,so it’s good to know how to get it.In order to help understand it
soomthly, we give one example here,now the max height in the board is 270mm,this is Initial
data,need confirm the current.
1 find data and change
Open the marlin /Configuration.h
Editor > search
Search for “#define MANUAL_Z_HOME_POS”
Notice: 270 is the height of the machine,Replace it with 310.
Then upload,pls disconnect repetier when flash firmaware.
You could Check the progress of the upload from there.
When it read finished, the upload is succeed.
2 test and confirm
Connect printer to PC
Home the axis’s pulley(input g28 on the Manual Control)
All axis will go up to the top position after that
Send m114 to check the Z axis’s coordination
As you could see The Z axis is 310mm at this time（record as A）
Send ”g1 z40” to let the nozzle down to the position higher than the plate about 20cm
Then Down the nozzle close to the plate manually by 10mm，then down 1mm every steps until it
nearly touch the plate，(put a A4 paper between the nozzle and the plate）down the nozzle by
0.1mm carefully until the nozzle touch the paper would be OK
There should be a A4 paper gap between the nozzle and the plate at this time
Input m114 to check the coordination of Z axis again
The height of the nozzle is 11.4mm at this time（record as B）
The right height of the machine could be figure out with A and B:
right height = A - B
310mm-11.4mm=298.6mm
Disconnect repetier and open marlin/Configuration.h
editor—search：#define MANUAL_Z_HOME_POS
replace 310 with 298.6 then upload,and it’s successful to change the new max height from 270mm
to 298.6mm,the current max height is 298.6,this is only one example.
4 Offline printing
1 load the model
2 slice
3 Export Gcode file
4 Copy
Copy the Gcode file to SD card and insert the SD card into LCD
5 Printing
See “print from SD”,choose it and press
See the Gcode file”test model”,choose it and press,then start printing
5 Heated bed
if use PLA filament,no need open heated bed.
If use ABS filament,need open heated bed, set the heated bed temp 85-100℃
Must connect heat bed line to board heated bed sensor to board.
If use repetier to control the printer, can see heated bed choose,can set heated bed temp.
If can not find heated bed choose,only show as the follow pictrue
Pls open the firmware,find the word “#define TEMP_SENSOR_BED 0”,Modify 0 to 1,then be
“#define TEMP_SENSOR_BED 1”.after this,flash the firmware to board again,then can see the
heated bed choose.
6 Problem and advice
1. The computer can not install arduino and other software
this situation often occur in the windows10, you can download Arduino1.6.1 online, pay attention to
the correct version.
2. The computer cann’t installed the drive
first enter the device manager to find the port item, double-click the unknown device port (unplug
the motherboard, the port disappears, connect the motherboard, the port appears, the port is the
printer port), click the 'update driver' button, then click find the driver software the computer ', and
then in the' Browse 'to find your driver address, the next step, that’s ok.
If you connect the motherboard and computer, in the device manager port, nothing did appear,
there may be a problem with the motherboard, please contact us
3.marlin upload failed
Marlin toolbar configuration may be wrong, the board (2560), processor (2560), port (2560),
programmer (USBtinyISP) need to select the right
Repetier connection is not disconnected
Arduino don’t be installed on right location ,don’t be installed in C drive
arduino version wrong, the correct version is 1.6.1
4.repetier interface nozzle temperature is 0, the display shows "MINTEMP"
Nozzle temperature sensor / white line in the motherboard slot inside the loose, another direction
to tighten
may be the nozzle temperature line / white line is broken, measured with a multimeter,the
resistance is 100K, you can also insert the hot bed temperature Sensor into the nozzle temperature
sensor slot to check.
5. There is no heating function for the hot bed
There is no heating function for the hot bed at the repetier interface, or 0 for the repetier hot bed
Modify marlin parameters on the hot bed and then upload (refer to the instructions attached)
6 hot bed can not be heated
if temperature sensor can not read the temperature hotbed can not be heated, you can use a
multimeter to check the white line is normal or through the exchange of the nozzle white line test
if there is a problem with the power supply you can not heat the hot bed ,then you can detect
whether the power supply output voltage is 12V by a multimeter or whether power indicator light
shine (the premise is to ensure that the customer's state voltage is 220V)
may be a hot bed is broken, hot bed directly connected to the power supply to check whether it
can be heated
motherboard may be a hot bed slot is broken, with a multimeter to detect whether the voltage is
12V
7. The hot bed can be heated but not reach the specified temperature
Under normal circumstances can be heated below 100 degrees, and can not be more than 100
degrees is the power of the current / power is too small, you can recommend customers to change
a greater current / power, such as 12V / 30A
very low temperature can not reach, such as 50 degrees, 70 degrees, 90 degrees this is the hot
bed problem, can directly connected hot bed and the power to detect.
8 Motor does not operate or does not work properly
When enter G28 ,there is motor not working / the shaft does not rise, it may be the axis above /
corresponding to the limit switch is broken, manual closing switch input M119 If repetier the
following information bar always shows "triggered" /don’t display "open" Then this switch is bad, or
use a multimeter to test whether the switch on the motherboard slot has a 5V output voltage
can ask the customer if the other machine function is normal, such as G28, fans, heating head, if
only g28 can be used, other instructions can not be used, may be using a different version of the
repetier, the correct version is 1.0.6
LED indicator on the board does not shine, does not light show the motherboard no voltage ,so
may be the motherboard problem
measure the output voltage of the power supply, if the output voltage is 12v ,that is normal,
there is no output voltage or output voltage is low will cause the motor does not work.
motor vibration, a lot of noise, this is because the motor voltage is not right, you can measure the
voltage on the motherboard port, 0.5v is normal, you can also measure the power supply output
voltage, the output voltage will cause this situation.
Extruder does not work, in the repetier interface, you need to enter m302. If the extruder does
not turn during printing, there may be no voltage on the motherboard port, or the motor is broken.
If you are not effective you can re-upload marlin
9. Leveling issues
If auto leveling starts in mid-air, it is because the auto-leveling limit switch is not plugged in or
broken. Input M119 Check repeteir information bar z min switch status, open normal / triggered is
not normal, may be effector are not flexible ,After switch be triggered can not be rebound to the
initial position of the effector, switches may be broken (regardless of whether the switch is triggered
or not "Triggered" means the switch is broken
If when leveling you found the center of hotbed is higher than around, because the nozzle is
not caused by the surface movement, you can modify the marlin to change the curvature. See the
leveling tutorial for more information
10. Printer filement are not discharged
may be filement in the nozzle blocked, then open the nozzle to inspect
It may be that the filament are stuck in the extruder, check if the filament is too wide to cause the
filament can’t pass through the extruder.
Check whether the extruder is working normally, and at the same time, feel whether the
consumable at the feed inlet is in.
Check repetier parameter configuration (please refer to instruction manual)
11.If there problems with auto leveling and nuzzle collides to the hotbed, you can adjust
the two screw on the effector as follows:
