PART LIST

MAIN PARAMETERS

ASSEMBLY

1. Install the frames After assembly of frames
   Note:
   The position of each frame cannot be changed.
   The countersunk head pore (the enlarged part) of Y-axis front profile faces inside.
   
   1. Install the frames
      Screw M5*20 x 4
      The countersunk head pore of Y-axis front profile faces inside. And the graduated side faces up. The profile scale is used to measure the sizeof the engraved object.
      

1. First you need to install the frame while you don't need to tighten the screws;
2. Make sure all profiles align.

2. Install the foot pads
   Screw M5*10 x 4
   1. Push the foot pads in. First tighten the screw M5*10 in blue area, and then ighten the screw M5*20 in green area
      Screw M5*20 x 4
   2. Finally, tighten the M5*20 screws in red area. Note: Please follow the steps above to tighten the M5*20 screws.
      

Check whether the POM wheel of the left and right parts of the Y-axis fits the profile and whether the movement is smooth and there is no jam

Note:

1. It is the most appropriate position to feel a little friction between the POM wheel and the profile when rotating the POM wheel.
2. If the wheel rotates in the air and does not fit the profile, the eccentric nut can be adjusted clockwise from the direction of the screw head with an open-end wrench.

4. Adjust the X-axis beam to make sure it is parallel with the front and back frame.
   Note: When installing, please make sure that the X-axis beam is parallel to the front and rear beam profiles. You can use the rectangle on the scale for auxiliary adjustment. Without parallelism, the Y-axis will be difficult to move and affect the engraving effect.
   

6. Install the bellows holder and Fixed-length column holder
   

7. Install the motherboard box
   

8. Install the bellows
   

WIRING

Note: Incorrect connection between X-axis and Y1 motor line will lead to abnormal movement.

ADJUSTMENT

REFERENCE OF MATERIALS

For engraving:

For Cutting:

Note:
The energy value is set to 500, and the laser intensity accounts for 50% of the power. The energy value is set to 1000, and the proportion of laser intensity to power is 100%. The larger the energy, the faster the speed can be set. The above parameters only for reference. Due to the different properties of the materials, please adjust the parameter values according to the actual situations.

ADJUST THE FOCUS

TTS-55 PRO

Focus adjustment before engraving: Before engraving, the focus need to be adjusted. The focus needs to be on the surface of the engraved object. It can use a fixed-focus column for auxiliary adjustment. Place the fixed-focus column between the engraved object and the adjustment block, and rotate the Z-axis lifting module to make the laser module stick on the 1st steps of the fixed focus column.

Focus adjustment before cutting: (Be careful of damage to the laser hood by impact)
Before cutting, the focus needs to be in the middle of the fault of the engraved object, so according to different plate thicknesses, the corresponding focus should be set, and the Z-axis lifting module should be rotated to adjust. Assuming the object is 2mm, use the 2nd step of the fixed focus column; The object is 4mm, using the 3rd step of the fixed focus column; The object is 6mm, using the 4th step of the fixed focus column.

TTS-10 PRO

Focus adjustment before engraving: Before engraving, you need to adjust the focus. The focus needs to be on the surface of the engraved object. The height of the fixed-focus column is 23mm. You can use the fixed-focus column for auxiliary adjustment. Place the fixed-focus column between the engraving object and the adjustment block, and rotate the Z axis. The lifting module makes the laser module stick to the fixed focus column; the laser module and the engraving object keep 50mm, and the adjusting block and the engraving object keep 23mm.

Focus adjustment before cutting: (the laser module protective cover needs to be removed)
Before cutting, the focus needs to be in the middle of the fault of the engraved object, so according to different plate thicknesses, the corresponding focus should be set, and the Z-axis lifting module should be rotated to adjust Assuming the object is 2mm, use the second step of the fixed focus column, and keep the adjustment block 22mm from the engraved object. The object is 4mm, the third step of the fixed focus column is used, and the adjustment block is kept 21mm from the engraved object

GRBL INTRODUCTION

1. Software Downloading
   LaserGRBL is one of the most popular DIY laser engraving software, which can be downloaded in LaserGRBL website http://lasergrbl.com/download/ (The installation package is also available on the TF card from the manufacturer or USB flash disk). Brief introduction: LaserGRBL is easy to use. However, LaserGRBL only supports Windows system (Win XP/Win 7/Win 8/XP/Win 10). For Mac users, you can also choose LightBurn, which is also an impressive engraving software, but it's not free. And this software also supports Windows system.
   Note: The engraving machine needs to be connected with the computer during engraving, and the software of the engraving machine cannot be turned off.
2. Software Installation
   Double click the software installation package to start the software installation and click "Next" until the installation is complete.
   

3. Language
   Click "Language" on the menu at the top to select the language you need.
   

4. Load Engraving File
   Click "File" and "Open File" in turn, as shown in figure 8.1, and then select the graph you want to engrave. LaserGRBL supports files in the formats of NC, BMP, JPG, PNG, etc.
   

5. Set picture parameters, engraving mode and engraving quality.
   
   1. LaserGRBL can adjust the sharpness, brightness, contrast, highlight and other properties of the target graph. We can preview window effect during adjustment, and adjust the effect to your satisfaction.
   2. In the engraving mode, "Line-to-line Tracking" and "1Bit Shaking" can usually be chosen;"1Bit Shaking" is more suitable for carving grayscale graph. Please Choose "Vector Diagram" or "Center Line" if you need cutting.
   3. Engraving quality essentially refers to the line width of laser scanning. This parameter mainly depends on the size of the laser spot of the engraving machine.
      Note: The recommended engraving quality range is 12-15. Different materials have different reactions to laser irradiation, so the specific value depends on the specific engraving material.
   4. At the bottom of the preview window, the graph can also be rotated, mirrored, cut and so on. After completing the above settings, click next to enter the settings of engraving speed, engraving energy, and engraving size.

6. Set engraving speed, engraving energy, and engraving size
   1. The recommended engraving speed is 1000, which is considered to be a relative appropriate value after repeated experiments. Of course, you can increase or decrease this speed according to your preference. A faster engraving speed will save time but lead to the decline in the engraving effect. Slower speed is the opposite.
   2. In laser mode, there are two instructions: M3 and M4. M4 instruction is recommended for engraving in "1bit jitter" mode, and M3 instruction is recommended for other cases. If you have only M3 instruction on the laser, please check whether the laser mode is used in the GRBL configuration. Please refer to the official instructions of LaserGRBL for GRBL configuration.
   3. Choice of engraving energy. Choose it according to different materials.
   4. Finally, set the size and click the "Create" button to complete the setting of all engraving parameters.
      

Save GCODE file
Click "File" in the menu at the top of the software interface, enter the drop-down menu, and select "Save".
