Do not put the knob with force as accurate combination is required. Instead, proceed attaching process again. * Make sure to turn off the printer power to separate/install the detachable extruder, proceed the work after temperature of extruder nozzle is completely cooled off. *. Mind possible scalding if the removable extuder separation/installation is unavoidable in high nozzle temperature condition. * Make sure not to install / separate detachable extruder with extreme force as it may cause the extruder part damage. * Printing in the case of detachable extruder is not properly installed to fixture part or removable setscrew is not tightened condition, may cause problem of the extruder installation or malfunction which make printing impossible. Make sure to install the extruder properly in prior to using the printer. * Make sure not to touch the extruder part or cause shock with wet hand as the extruder includes electric equipment. ① ②

46 11-2. Extruder maintenance Nozzle of the extruder is located at the bottom of the extruder and it is the part, which makes model as filament melts and comes out. Nozzle is the consumable part of the printer and can be worn out or filament carbonization leftover, impurities of filament might be piled up inside due to continuous nozzle use. Therefore regular nozzle replacement is required. However, in the case of improper nozzle control, several problems related to the nozzle can occur earlier than normal nozzle use period and it may cause poor printing quality. In the case of serious printing quality problem occurrence, the nozzle cover might be blocked and it requires the nozzle replacement. Regular nozzle cleaning is required for the nozzle continuous use with uniform printing quality. (1) Cleaning gear contaminants Turn off the printer power and pull out G_FAN from the extruder rear side. Be mindful that damage might occur in the cable pull out process.

47 Turn and separate the bolt from cover front in counterclockwise direction with wrench of 2Ø diameter. Be mindful of a gear fan, which is installed to the cover and separate the cover. Then remove all filament leftover and filament powder from the gear with the antistatic brush. Press the handle and clean dusts with antistatic brush.

48 The extruder gear can be rotated with D-gear of motion by turning the power ON in the extruder pullout condition. Make sure to rotate the gear pressing handle. In the case of cleaning with air compressor, quality decrease and equipment malfunction may occur due to powder insert to shaft. * Make sure to rotate the gear by pressing handle in the process of the gear cleaning. The gear abrasion may occur in the case of moving the gear without pressing handle. * Be mindful that equipment malfunction might be caused due to powder insert to the shaft in the air cleaning process. * Do not put conductive materials into cleaning part during the printer power is ON. It may cause equipment shock. (2) Cleaning of filament channel contaminants Basically, the extruder, which uses all provided material or mixes all materials are not recommended. Filaments have different property and temperature. Those differences may be accumulated slowly and they may cause serious problems. Even though the inside filament can be deleted in the time of using ABS during PLA use period, PLA ingredient may remain on a wall surface. Those filament leftovers are accumulated continuously and sometime they cause printing failure due to nozzle blockage (Below picture shows the phenomenon, which is caused by the filament mix.)

49 Make sure to remove the filament with tweezers, which is inserted to filament entrance of detachable extruder (3) Inside nozzle cleaning Cleaning inside nozzle is basically possible with filament loading. Clean the inside with nozzle control pin in the case of loading is impossible due to change of inside filament property caused by materials mix. Make sure not to push in forcefully as it may cause damage to inside. * Make sure to wear gloves as inside nozzle cleaning is proceeded in hot condition and be mindful of possible scalding * Make sure to work holding only plastic part of detachable extruder in hot condition. Metal part and rubber part are in hot condition. * Nozzle control pin is not required to be used often if it does not mix material.

50 11-3. Auto leveling interface part maintenance The extruder nozzle end part of Cubicon single plus touches interface part of heating bed and decides electric current applying necessity. Also, it recognizes the interval between heating bed and nozzle and adjusts bed height automatically. Therefore in the case of contaminants presence on heating bed interface part and nozzle end part, auto leveling will be failed due to poor electric current application. Make sure to clean contaminants for normal auto leveling operation. 3 points, which are indicated in red, in above picture, are used for auto leveling interface. The filament melts and puffs and it causes pollution in the process of auto leveling of heating bed auto leveling interface. Auto leveling failure occurs due to melted filament fixation in the case of not removing and neglecting pollution. Make sure to clean the interface part with tweezers or scraper in prior to printing. Above nozzle in the extruder picture is directly contacted part in auto leveling process. It basically proceeds cleaning it printing process, but it gets carbonized easily due to filament staining in printing process. Make sure to clean with a wire brush, which is equipped to an antistatic brush.

51 11-4. Heating bed maintenance The heating bed is a floor, on which printing material is formed by melting and extruding filament. The heating bed gets polluted easily by filament or filament pieces, which is melted and attached in the formation process. In the case of continuous printing in polluted condition, contaminants sticks at formation too, and it causes pollution of formation or poor formation attachment to the heating bed in the printing process. Make sure to maintain the heating bed in tidy place before and after printing to prevent poor printing quality due to printing material pollution. ① Remove filament leftover of the heating bed, using tools such as tweezers, scraper or a brush. Be mindful of heating bed surface damage in a tool use process. Lamination gets peeled off due to surface damage and it causes poor printing material sticking. ② Filament leftover or filament sign on the surface of heating bed in formation process may not be removed easily. Make sure to remove those serious pollutions wiping as if melting with right amount of high purity acetone. * Make sure to use only high purity acetone for the heating bed cleaning * Some stain may be seen on the heating bed surface. You do not need to concern on this matter as those stains usually occur in lamination process and do not effect to the heating bed property. * The heating bed lamination usage period depends on user’s printing habit. * The heating bed of Cubicon single plus can process printing without using kapton tapes in appropriate temperature in the case of printing our company’s ABS/PLA. However users can purchase and use kapton tape depending on their printing habit or printing model. In the case of melted filament printing method, contraction may occur if melted filament is hardened and it may lead to printing floor bird-caging. Contradiction can be improved depending on printing temperature condition or heating bed adhesive strength or slicing option change. Most of contradiction phenomenon occurs often and contradiction difference occurs based on contradiction degree. Make sure to consider a design method, which can disperse contradiction force in 3D model designing process. * Do not use solvents other than aceton for the heating bed as they lead to lamination damage. * Make sure that aceton shall not stain onto other objects in the time of using aceton for heating bed cleaning as it may lead to the product damage. * Make sure to use aceton in well ventilated place and be midful of aceton maintenance. (Make sure to follow safety regulations, which is written on aceton package) * Do not use a wet tissue as abluent ingredient of some wet tissues may lead to heating bed lamination pollution. * Do not seprate or force the heating bed for formation pullout as it may lead to heating bed malfunction. * Auto leveling is adjusted with unlaminated bed part. Make sure to remove foreign substances in prior to printing.

52 11-5. Filter replacement Purafil accelerator, HEPA filter, clear filter, which consist of triple structure of deodorizing filter is used for filtering out contaminants, which occurs from a printer of FFF type in Cubicon single plus. Contaminants of the clean filter may cause not only poor filter performance but also filter fan operation interference and lead to the product malfunction. Do not cleanse polluted clean filter. But replace it with new one. Replacement period of the clean filter depends on the product use environment and user’s printing habit. Generally, it is recommended to replace the clean filter every six months. Make sure to install the clean filter to a case in appropriate direction. Inappropriate installation may lead to poor filter performance and a fan malfunction. 11-6. Rubber brush & wire brush replacement period and method Heat resisting rubber cleaning brush and wire brush are attached to the left side of heating bed for cleaning the end part of nozzle. Make sure to remove filament leftover as it may cause secondary nozzle pollution. Those two brushes are consumable products. Therefore, user can replace those products through designated A/S center in the case of product damage. Replacement period of nozzle cleaning brush is when the brush cannot function properly due to filament leftover and the brush replacement is required in this case. Continuous brush use without replacement may lead to auto leveling failure and nozzle shock. ① Press fixture to the bottom part of rear socket and pull out socket Bottom part fixture Pull out ② Take out the bed by pulling it up ③ Rotate and untie the bed in 2Ø wrench counterclockwise direction.

53 ④ Untie in 2.5Ø wrench counterclockwise direction.  Replace a brush in complete separated condition. * Make sure that bed temperature is cooled off and its power is OFF in prior to proceed work. * Make sure to wear gloves in separation/installation process to prevent hand injury as the bed is fixed with extreme magnet force. * Assembly is the vice versa of separation. 11-7. Firmware update User can download the firmware from Cubicon homepage and install new version of the firmware. (1) Firmware installation by cubicreator Setting –Install new version of the firmware after selecting updated firmware and a file to install. (Refer to the cubicreator manual for detailed information.)

54 (2) Firmware installation through USB memory Create ‘Firmware’ folder in ‘Root’ folder of USB memory. Copy UI file and new version of firmware into ‘Firmware’ folder. Select firmware icon of ‘Setting’ after inserting USB memory to Cubicon single plus. Firmware update starts, once ‘Download’ button is selected. Make sure to initialize after firmware update completion-rebooting. Initialize process takes no more than 1 minute.

55 11-8. Firmware recovery Cubicon Single Plus has the function to recover previous firmware to prevent any possible problem in firmware update process. (1) Operation method Keep pressing ‘Reset’ button after the printer power is OFF. Keep pressing ‘Reset’ button for 20 seconds after the printer power is ON to recover previous firmware recovery. Touch LCD reset and rebooting means successful recovery completion.

56 12. Trouble shooting * The printer hardware problem can be solved by initializing through {Setting > Function > Initialize} or through firmware update. * Printing quality can be different depending on printing condition or cubicreator option setting in G-Code process. Therefore make sure to check quality using different printing condition or option. It is important to inspect problem source clearly in the case of equipment problem occurrence. Make sure to film of modelling file (STL), hfb(hvs) file, related problem picture and video to provide for customer support. 1) USB memory data is invisible.  Cubicon Single Plus supports only formats in FAT32 form file system.  Cubicon Single Plus supports only English named files. In the case of file names in different languages, letters may break or it may seem as empty blank. Therefore make sure to change file name from other language to English for proper use.  Printing might be interrupted in the case of including characters such as “.“ in file name. (System recognizes “.“ from back as filename extension)  Only *.hfb and .hvs files are visible on LCD screen of Cubicon Single Plus. Make sure to check if a file is copied properly into USB memory.  Printer may recognize up to 255 USB memory files. Make sure to arrange files in proper quantity. 2) USB memory data cannot be printed.  Make sure to check if selected files are in G-Code of *.hfb , *.hvs filename extension. Only sliced G-Code (*.hfb , *.hvs filename extension) files can be used by cubicreator in Cubicon Single Plus. G-Codes, which use different slicing programs, cannot be printed and they may cause equipment damage.  USB memory data might have been damaged. Try to remake and use remade G-code file.  Printing cannot be processed in the case of improper implementation in memory copy process after slicing by using cubicreator. Make sure to use the cubicreator and check if related G-Code is proper to use. G-code is improper to use in the case of abnormal printing channel, which is shown as G-Code.  Slicing might have been gone wrong through the cubicreator due to improper 3D model. Import original 3D model from the cubicreator and check if there is any problem in slicing or G-Code transmission normality. Use special 3D model inspection program and check any possible problem of 3D model.  There might be a problem in USB memory data storage due to security program of PC or virus. Take appropriate measures for soling problem after inspection and try again. 3) Printing cannot be proceeded due to PC and USB cable connection. Check if there is any problem in PC and printer USB cable connection.  Check if Cubicon Single Plus driver is installed to PC properly. . Check if PC problem is related to virus and reinstall driver after solving the problem.  Connection problem may occur due to communication problem of PC and printer. Try to reconnect USB cable or rerun the cubicreator or turn OFF and ONN rear power button. 4) Printing cannot be proceeded due to PC and WIFI connection  Check if PC and the printer are connected to identical router. Use the printer and PC in places, where WIFI is well connected.

57  Connection interruption may occur depending on a wireless router model.  Try to initialize the printer setting or turn OFF and ON the printer power.  Refer to 22P for detailed information. 5) Filament cannot be extruded with the nozzle.  Check if the filament is a genuine product. Some filaments have different temperature condition from other genuine filaments and problem may occur in extruding process due to those filaments’ serious temperature change. Serious temperature change may lead to the extruder malfunction. The printer malfunction due to non-geniune filament use is excluded from complimentary A/S.  Check if the filament supply is normal. Untie and rearrange the filament in the case of problems such as the filament twisting in a spool or untied filament. It is highly recommended to untie and rearrange filament as twisted or untied filament may cause continuous problem.  The filament nature may change from its original nature due to pollution such as humidity or dust. Such filament use may cause malfunction such as extruder blockage. Use opened filament as soon as possible and keep the filament in fixed condition in the spool using plastic to prevent the filament from humidity/dust. Make sure to keep the filament only for short period.  Check if supplied filament is not too thick or not too thin either. The filament in 1.6~1.9mm diameter shall be used for accurate filament supply in Cubicon Single Plus. Using too thin or thick filament may be inserted to equipment and it may lead to equipment malfunction.  In the case of inside extruder filament gets twisted or caught in equipment, extruding cannot be processed due to extruding problem. Make sure to separate detachable extruder and remove problematic filament. Inside extruder twisting problem may easily occur in the case of filament of low printing temperature. Twisting problem can be solved by adjusting inside equipment temperature to low degree.  Check if detachable extruder installation is proper. Error message may occur on LCD screen in the case of problem occurrence.  Check if filament in use and the printer extruder temperature are proper.  Replace damaged nozzle. The nozzle is consumable product and can be replaced through A/S. 6) A model is not attached to a floor (heating bed) and is detaching.  Check if filament is genuine product. Some filaments are not glued to the manufacturer’s heating bed and it may cause equipment malfunction in printing process.  The filament nature may change from its original nature due to pollution such as humidity or dust. Those polluted filaments may be glued to the heating bed poorly. Use opened filament as soon as possible and keep the filament in fixed condition in the spool using plastic to prevent the filament from humidity/dust. Make sure to keep the filament only for short period.  Remove contaminants from heating bed. General wet tissues may cause damage to heating bed lamination. Never use wet tissues for heating bed.  Check if filament in use and heating bed, extruder temperature condition are proper. The heating bed use in Cubicon Single Plus can be glued well if only it can maintain proper temperature condition with filament in use. And the temperature condition can be different depending on printing environment.  Check if the heating bed attachable area is not too small or formed floor is not irregular. Use a floor supportive material option in the G-Code formation process or slow down the first layer printing speed to solve the problem.  Use proper tape if required. Applying special heat resisting tape such as kapton tape to heating bed in accordance with formed model or filament type, might be helpful for a model attachment. Corner

58 contact point which is auto level shall be attached with exposure. Make sure to calibrate tilt offset as thick as tape thickness.  Check if the heating bed lamination has not been damaged or the heating bed bending is not serious. Replace heating bed in the case of heating bed lamination damage or serious heating bed bending. The heating bed is consumable material and can be replaced through A/S. 7) A part of the model, mostly floor border detach from the floor.  Refer to “6) A model is not attached to a floor (heating bed) and detaching” and take appropriate measure.  The problem can be solved partially with option such as inside fill density in G-Code formation process.  Material contraction from heat melting printer is the main reason. Adjust printing condition (extruder, heating bed, printer inside temperature) or use less contracted materials. Contraction can be improved somewhat depending on material. However model modification is the most effective method for contraction improvement, which appears by filament solidification as natural phenomenon. 8) The middle of model is cracked.  This is caused by contraction of the material caused by printer using the thermal melting method. Adjust printing condition (extruder, heating bed, printer inside temperature) or use less contracted materials. Contraction can be improved somewhat depending on material. However model modification is the most effective method for contraction improvement, which appears by filament solidification as natural phenomenon.  The problem can be solved partially with option such as inside fill density in G-Code formation process 9) The model does not detach from a floor (heating bed)  Wait until heating bed cools off sufficiently. Forceful pull out may harm the heating bed. The model is attached onto the floor in the heating bed printing process of Cubicon Single Plus. The model can be detached easily, once the heating bed cools off after printing completion. Proper temperature for the model detaching is different based on the filament and model model and environment.  In the case of heating bed cannot be detached after heating bed cooled off (cold temperature), try to pull out the model by pushing its floor part with flat ended object.  In the case of continuous model leftover fixture to the heating bed, the model cannot be detached from bed as it is attached to fixated leftover. Make sure maintain the heating bed surface tidy.  Replace the heating bed in the case of heating bed lamination damage through A/S. 10) The model is printed partially or it is not printed at all or it is printed abnormally.  Refer to “5) Filament cannot be extruded with nozzle.” and take appropriate measure.  Check printing model and G-Code. Problem may occur in G-Code formation process in the case of abnormal model. Modify model and try again.  Problem may occur in printing due to printed model and stanchion interruption based on model or stanchion in use. The problem can be solved in the case of slicing method change (slicing option adjustment or direction change).  Remove contaminants from inside nozzle.  In the case of continuous problem occurrence although proper model, the nozzle shall be replaced by A/S.

59 11) Printing cannot be processed due to auto leveling failure.  Check if environmental vibration affects equipment in auto level process. Auto level may fail in the case of vibration transmission to equipment.  The printer proceeds auto level of bed in prior to print. The printer stops printing in the case of auto leveling failure (automatically proceeding for several times) due to some reason.  Make sure to maintain auto level contact point continuously.  In the case of continuous problem occurrence, replace extruder cleaning brush or heating bed by A/S.  Auto leveling may fail depending on temperature and filament difference in non-genuine filament use. 12) The presence detection sensor of filament is not operated properly.  Make sure to check supplying filament’s diameter is 1.6~1.9mm in prior to use it.  Flexible filament such as TPU may malfunction due to filament pressure to supply detection sensor. Make sure not to use filament supply detection function in this case. (Setting > Function > Filament Check “Off”)  The filament detection sensor may get worn out due to continuous use as it is consumable material. Replace the presence detection sensor through A/S. 13) Operation stops in printing process.  Check power supply. In the case of continuous problem occurrence take a photo or video of problematic part and use A/S.
