—— Michael May

received the device... smooth transaction definately work with them again

—— Steve Lent

Excellent packaging in wooden crate. Good communication with seller. Machine looks well built.

—— Gord Priest

The supplier is good, goods supplied completed as their mention and good packaging. Just for remember the expedion FedEx local very bad for delevering

—— sutrisno sarudji

Supplier is very good. We got the order with little damage due to transport(Courier) but they replaced by sending that alone and helped thru online

—— Balaji Rajamanickam

I have received my machine in good shape include software and instruction manual. that's very perfect!

Laser engraving machine operating instructions and troubleshooting methods

First, the workpiece

You can select the machining process is completed filing location , and use the software speed processing speed, strength and precision machining . As for image processing , but also a corresponding grid based system , the end of the frame to adjust the first output , to determine the position of the workpiece on the table , and then placing the workpiece , the workpiece according to the software put in output (printing ) and wait until the laser engraving machine to receive documents, engraving machine can be started after receiving the file to locate key march red ( red light positioning : open the cover before the formal process , press the start button for file output, the laser does not emit laser tube can be observed machining position is accurate, to avoid waste generated by positioning allowed ) , and then press the Start key processing.


( 1 ) When using the automatic measurement focus , pay attention to the automatic measuring rod must be tightened focus , otherwise the work surface to the top of the laser head and off the track.

( 2 ) Laser engraving machine at work, prohibit open the cover ( top cover and front cover ) , otherwise it will stop the laser emission , affecting processing quality.

( 3 ) When the workpiece must be open and blowing smoke exhaust equipment to prevent dust pollution focusing lens and reflector lens , otherwise it will affect the lens focus and reflection , and thus indirectly affect the processing strength and precision.

( 4 ) the processing of wood , when the paper artifacts, must pay close attention to processing speed and processing strength , to avoid too slow, too high intensity flame . Flame will damage the focusing lens , the light intensity of the impact of processing , precision , heavy machine will not be used.

( 5 ) For the initial user performs irregular workpiece when the red light must be positioned to determine whether the location is accurate machining , or prone to waste.

( 6 ) Processing of thin wood, cardboard and other deformable material, to adjust the horizontal deformation amplitude difference is less than 1 mm , the focal length is too large to avoid affecting the machining accuracy. To the processing of paper sheets fixed to avoid displacement occurs . When cutting the paper , especially the quality of soft paper ( rice paper , Mao Bianzhi ) , the first of its stacked 15-20 sheets soaked with water , after leveling , and then cut. This will improve efficiency, while avoiding the risk of burning due to the emergence of the material .

(7 ) for cutting , the workpiece holder to make more than 2 cm away from the work surface to avoid artifacts caused by the laser reflection back to damaged , resulting in waste.

( 8 ) Clean the lens and focus lens reflex : Two- finger pinch reflex lens , one hand with the photographic lens cleaning paper moistened with cleaning fluid and gently drag the lens surface , prohibit the use of finger pressure to avoid scratching the mirror ; or with a cotton swab dipped in the cleaning solution and gently wipe the camera lens to focus the lens until smooth .

( 9 ) is usually carved vector file , the resolution should be chosen higher (500dpi or 600dpi); Chen points carving documents should choose lower -resolution (500dpi rough mode or 300dpi). This sculpture will be good.

Second, common faults and processing methods

( 1 ) how to save time

In mass production with the specifications of the small size product ( such as 75X25mm badge ), X direction should be less than the maximum width of 300mm, so you can make the laser head to the opposite faster, thereby increasing speed. When carving a bitmap , may be appropriate to reduce the resolution to speed . In addition, the laser machining depth and power, speed is proportional to the power under the same circumstances , the faster the more shallow depth of carving , and vice versa deep, so it should be possible to improve the speed and power to shorten the time.

( 2 ) how to avoid waste

Standard configuration is generally laser engraving machine has red pointing device. Irregularities in the processing of the product , first observed with red light positioning engraving position is accurate, then the formal processing. For material not seen before , you should follow the power from low to high principle.

( 3 ) No laser machine

Check the cover, the front door magnetic switch and wiring loose , falling ( Shandong has a user , the night before the first day of work, the machine clean from the inside out , and the next morning found that the machine does not emit laser , the inspection is to rub the magnetic switch the machine off when the line is caused ) . Then check reflections, questions whether the focusing lens ( Beijing after a user to wipe lens reflex , no screws tighten , causing the lenses loose, causing no laser ) . If not the above reasons , you must contact the maintenance staff , please do not deal with on their own.

( 4 ) a large area engraving , cutting shades

This is due to the errors caused by the laser light path . As long as the light path alignment on the line ( at the time of purchase have specialized training ) .

( 5 ) engraved font distortion

A, if the head after the car badly worn pulley , causing the car head loose , replace the pulley.
B, if the Y -axis direction is not the same as the left and right sides of the belt tension , adjust the Y -axis to the rear hex screw tension consistent .
C, if the X -axis on the left side of the driven wheel wear , replace the driven wheel .
D, if the X -axis motor failure , replace the motor.
E, if the X -axis motor fastening screws loose pulley , then tighten the screws.

( 6 ) engraving machine carve , memory is bad or damaged. Reinstall the memory or replace the memory.

( 7 ) computer interface to be set to SPP

( 8 ) Data cable away from sources of interference

( 9 ) computers and laser engraving machine is best to use the same socket , to avoid potential difference.

( 10 ) Power sudden decay half of the laser tube failure, only returned for repair .

( 11 ) Power gradually decay

First, you should check whether the focusing lens reflex lenses and clean, the optical path is not correct . If there is no problem, promptly contact your service personnel.

( 12 ) When a large area engraving and cutting , appear as shades of cases the problem is not material . It must be the light path is not correct .

( 13 ) failure of automatic measuring stick coke

Mostly due to the flat cable connected thereto damage caused by the replacement of normal use .
