The calibration requires to be set only for the first use. Operation steps: A4 paper Heated bed Leveling X: 20 Y: 20 Z: 20 0.06 mm 1 mm 10 mm Leveling X: 20 Y: 20 Z: 20 0.06 mm 1 mm 10 mm Press the "Entrance to 3-point leveling interface" button Place a piece of A4 paper on the heated bed Press the "3-point leveling mode initiate/Point recording" button to enter 3-point leveling mode, and the nozzle will automatically go to a position right above Point æ Press the "-Z" button to get the nozzle closer to the heated bed, and move the A4 paper back and forth at the same time. Stop just when the paper can slip with slight friction Leveling Leveling X: 20 Y: 20 Z: 20 X: 20 Y: 20 Z: 20 2 0.06 mm 1 mm 10 mm 0.06 mm 1 mm 10 mm Press the "3-point leveling mode initiate/Point recording" button to record Point æ, The nozzle will automatically go to a position right above Point ç after successful recording Do the same height adjusting and point recording steps to record Point ç and è. After successful leveling, the machine will home again and exit 3-point leveling mode 3 1 Note: 1. Please access to www.dobot.cc to download and upgrade the mainboard firmware! 2. 3-point leveling mode can only be entered with 3D printing head connected. 3. Only Z coordinates will be recorded, so all you need to do is adjusting the height with a piece of paper. 4. The recorded points will not be lost after power-off. But, once entering 3-point leveling mode, previously recorded points will be cleared automatically. 5. Friction status of the three points should be as uniform as possible. Pay attention when traveling the head downward, especially when the nozzle is getting too close to the bed. Even though the height detect protection will take effect and force the machine to go 0.06mm each press, the heated bed may also get burnt if you continuously move it downward without testing the height with a piece of paper. 6. A re-assembled machine should be re-levelled. 7 3.2 Set the Zero Point Zero point is the start point for the machine to print, which requires to be set only for the first use. Operation steps: Control Tools X: 20 Zeroing Y: 20 0 mm Z: 20 X: 20 Zeroing Y: 20 0 mm Z: 20 A4 paper Heated bed 0.06 mm 1 mm 10 mm 0.06 mm 1 mm 10 mm Press the "Entrance to control tools interface" button Press the "Entrance to zero Place a piece of A4 paper point setting interface" button on the heated bed Press the "-Z" button to get the nozzle closer to the heated bed, and move the A4 paper back and forth at the same time. Stop just when the paper can slip with slight friction Press the "Zero point updating" button to record the position of zero point. The machine will home again after successful recording Fine tuning: This function allows users to fine tune the zero of Z-axis according to bonding status of the first layer, in case the zero point is not satisfactory after standard setting procedures. For instance, if the zero point is too high and causing bonding failure of the first layer: X: 20 Zeroing Y: 20 0 mm Z: 20 0.06 mm 1 mm 10 mm X: 20 Zeroing Y: 20 0 mm Z: 20 0.06 mm 1 mm 10 mm Press " - " button to set a negative fine tuning value Press the "Zero point updating" button to fine tune the zero point with the value you set. The machine will home again after successful updating Note: 1. Only the zero of Z-axis need to be set and recorded. Zeros of X-axis and Y-axis are system default values and will not and cannot be changed. 2. Too high Z-axis zero position will lead to loose bonding at the bottom, causing the model falling off, and too low position will make it difficult to take off the model or even scratch the heated bed. Dedicated fine tuning is always required to obtain satisfactory first several layers. If the zero point is too high, please use a negative fine tuning value and use a positive fine tuning value if the zero point is too low. 3. Pay attention when moving the head downward, especially when the nozzle is getting too close to the bed. Even though the height detect protection will take effect and force the machine to go 0.06mm each press, the heated bed may also get burnt if you continuously move it downward without testing the height with a piece of paper. 4. The zero point will not be lost after power-off, so there's no need to reset it. However, the zero point may be deviated and needs to be reset after the reassembling. 5. If your printer prints in the mid air, the zero point must be wrongly set. After correct zeroing and homing, the coordinate of Z should be about 100. 6. Please be prudent with the "Zero point updating" button, pressing it will change zero point of the machine. If the fine tuning value remains 0, the operation will record current height of the nozzle as zero point. If the fine tuning value is not 0, the operation will update zero point of Z-axis using fine tuning value you set. 8 3.3 Install/Remove the Filament Operation steps: Control Tools Function T:25¥/ 200¥ B:25¥/ 60¥ Function T:25¥/ 200¥ B:25¥/ 60¥ Press the "Entrance to control tools interface" button Press the "Entrance to functional module control interfaces" button Press the "Preheat nozzle" button, and wait for the temperature to reach about 200ºC Press " " button until melted filament flows out of the nozzle Note: 1. In case filament need to be unloaded: preheat the nozzle to tartget temperature and pull the filament out. 2.

After setting parameter according to the next page, click Slice to generate Gcode file. View the details of the slice: Click the drop-down list on the upper middle corner of the interface and select"Layer view"to view the details of the slice. Layer view Layer view PREVIEW Slice 11 Description of key profile settings: æ Layer Height: For the height of each layer of printing, smaller value will produce finer surface, but cost more printing time. Suggested range is 0.05 to 0.3, not exceeding 3/4 of the diameter of the nozzle. MOOZ used 0.4mm nozzle, means not exceeding 0.3. ç Wall Thickness: For the printing thickness of the outer surface of the model, the setting of 1.2 indicates that the outer surface will go three rounds, since the width of each round equals to the diameter of the nozzle, namely 0.4. è Top/Bottom Thickness: Determine the bottom/top thickness of the model. é Infill Density: Determine the filling density of the internal grid of the model, generally set at 15% or less. ê Printing Temperature: Need to be set according to filament type. Suggested value for PLA is 200~210¥. ë Build Plate Temperature: Need to be set according to filament type. Suggested value for PLA is 60~70¥. ì Travel Speed: Travel speed should be set no greater than 40mm/s, otherwise the Z linear actuators may lose some steps when traveling downward from home position too fast and cause zero point deviation. í Support Placement: If the model has any hovering part, the option must be switched on. Generally, "Everywhere" indicates that support can be added on the model itself. If you select "Touching buildplate", it indicates that support can be added only between the print platform and the model hovering position, not on the model. î Build Plate Adhesion: "Brim" indicates that a few layers of outer ring should be added on the bottom edge of the model so as to prevent warping. And "Raft" is used to get the whole model raised by adding a raft-like base on the bottom when the heated bed leveling status is not satisfying. ï Spiralize Outer Contour (i.e., vase mode): Only the outer surface and the bottom of the model are printed, and continuous spiral lift will appear when printing the outer surface, which can improve the surface quality, but has requirements for the model, and that is, the model can only have one outer surface and can not be hovered. Note: 1. Hover the mouse over the option, and the corresponding hint will appear. 2. Right-click anywhere within the parameter setting area, you can "Configure setting visibility". 3.

For gradient mixing mode, the gradual color changing process will follow the CMYK chromatography in general. You can use image-editing software, Photoshop for instance, for accurate color configuration. Note: The principle of color mixing is only for reference. Due to the non-real-time and uniformity of color mixing, the color of actual printing will be slightly different from the theoretical setting. 1.

A maximum of 4-color switching is supported Apply the configured mixing scheme Estimated result Note: 1. If only one color block is configured and the others are left empty, the whole model will print with the very one color you configured regardless of the height parameter. 2. If you only want to use one or two of the three filament rolls, always set percentage of the filament you don't want to use to 0 when configuring. 3. Due to the uniformity of color mixing, there will be a partial gradient transition between actual layers. 13 2.

Make sure the machine has been properly leveled and zeroed before executing any Gcode files. We strongly advice you to check if the zero point is suitable by moving the Z coordinate to 0 manually and test the friction status with a piece of A4 paper. 2. After printing finished, please wait until heated bed cools down to ambient temperature. Place a knife or spatula under the print and apply a small amount of force to remove it. Do not try to drag or pull the print off, otherwise the heated bed sticker may swell and result in severe unevenness. Note: 1. The U disk or microSD card format shall be Fat32 with the capacity not greater than 32GB. 3. Applying masking tape before printing can greatly reduce risk of getting the heated bed sticker scratched!

If the issue is solved after unpluging the heating rod socket, please check if failure is caused by short-circuit of heating rod cables. Refer to Section 4.4 for maintenance. A : Check if the heating rod and heated bed are reversely connected. 4.3 3D Print Functional Module Failure Q : Able to heat nozzle, but unable to reach target temperature A : Check if the temperature sensor falls out of the heating block. Refer to Section 4.4. Q : Abnormal nozzle temperature, displays "0" other than ambient temperature A : 1. Check if temperature sensor cable is connecting to the correct socket properly. Refer to Section 4.4. 2. Use the spare temperature sensor to decide if the failure is caused by faulty temperature sensor. Refer to Section 4.4 for maintenance. Q : Unable to preheat the nozzle Q : Unable to extrude filament normally Q : Under extrusion, too little filament is extruded during printing A : 1. Check if nozzle temperature displays normally. 2. Check if the heating rod cable is connecting to the correct socket properly. Refer to Section 4.4. 3. Functional module is damaged. 4. Heating rod is damaged. A : 1. Check if the extruder motors are working normally. 2. Refer to Section 4.4 for maintenance. 3. Please do not mix-use filament of different type or brand. A : Carbonized material will accumulate in the nozzle after long time printing. To keep the print head in good condition, we suggest you clean the nozzle after every 1kg filament printing by applying the cold-pull method: Remove all three quick pipe connectors from the print head, then heat nozzle to 200~220¥, use your hands to feed filaments into the three channels simultaneously until all three filaments flows out for 5~15s. Stop heating and wait until nozzle temperature drops to 90~100¥, then pull out the filaments, in this way, the carbonized material may be pulled out together. Remove the bulged end and be ready for the next cold pull.You may need to perform the cold-pull 4~5 times to get the nozzle fully cleaned. 18 4.4 Maintenance of 3D Print Functional Module In case of clogging issue, leading to slipping or step losing of extruder motors: Please preheat nozzle to target temperature, press down the plastic part of the quick pipe connector 2 and remove the corresponding bourdon pipe 1 . Remove the swelling end and reinstall it. If the clogging issue is not solved by reinstalling the filament: Please refer to the last Q&A in Section 4.3 for maintenance of the nozzle. In case of replacing the PTFE pipe 5 , please screw off the quick pipe connector 2 and filament barrel cap 3 after heating nozzle to target temperature. Note: No need to disassemble the print head further to fix clogging issue. For replacing nozzle 16 or temperature sensor 9 , please follow the steps below: Remove the fixing screw of heat insulation block 7 , take down the whole print head from the triangular piece 17 . Loosen the fixing screw of heating rod 8 , for replacing the heating rod & temperature sensor suite 9 . Warning: Please follow the steps above to replace temperature sensor. Fitting area between the nozzle and filament barrel is sealed with sealant during factory assembling. Please do not try to loosen the filament barrel fixing screw . In case of replacing the nozzle 16 , please screw off the old one with a plier or wrench. You may need to heat the nozzle to about 160 first. Fit a new sealing gasket 16 into the groove of the nozzle, and tighten them on the heating block as hard as you can to prevent oozing issue 9 . Note: The sealing gasket is disposal and mustn't be reused. 1 Bourdon pipe 2 Quick pipe connector 3 Filament barrel cap 4 Filament barrel 5 PTFE pipe 6 Filament barrel cooling fan 7 Fixing screw of heat insulation block 8 Heat insulation block 9 Heating rod & temperature sensor suite 1 2 3 4 5 6 7 8 9 10 10 Heating rod fixing scew 11 Filament barrel fixing screw 12 Blower cooling fan assembly 13 Blower cooling fan support 14 Blower cooling fan support fixing screw 15 Heating block 16 Nozzle + sealing gasket 17 Triangular piece 11 12 13 14 15 16 17 19 Parameters Overall Dimensions: 350 * 325mm Adapter Input: 100-240V~50/60Hz, 1.8Amax Adapter Output: 12V~10A Main Material: Aircraft-grade aluminum Operation Panel: 3.5' LCD touch pad 3D Printing Nozzle Diameter: 0.4mm Layer Resolution: 0.05~0.3mm Nozzle Temperature: 250 Max.
