About Your Machine

Main Parameters:

Assembling the Machine:

• Installation of master control box: Place the master control box with the port facing up.
• Installation of bellows mounts: Use M3 X 6 screws.
• Installation of X-axis End Stop: Use M3 X 6 screws.
• Installation of Laser module: Attach the laser module.

Set up TTS-20 PRO:

• Bellows fixing: Secure the bellows to the seat with a cable tie.
• Adjustment of X-axis parallelism: Ensure the X-axis beam is parallel by loosening the screw at the bottom. The package does not include a ruler.
• Adjustment of timing belt: Lock the timing belt fixing screws on one side, pull the timing belt tight on the other side, and then lock the side screws. Check that the timing belt is hung on the X-axis motor.
• Adjust the focus: Adjust the engraving/cutting height using a fixed-thickness plate.

Machine Wiring:

Connect the X-axis motor cable, X-axis limit cable, and Y2 motor cable. Ensure proper wiring for Y2 motor pair, Y-axis limit, and laser module. After wiring, push the machine to move and check for wire interference.

Honeycomb Panel Introduction:

Use honeycomb pins fixed in the corners of the material to prevent buckling. Note: Stainless steel may deform with heat, making honeycomb pins less stable.

Stick non-slip sheets to the aluminium sheet: Confirm the position of the anti-slip sheet on the honeycomb board and apply it. Be mindful of the honeycomb board corner protection.

External auxiliary accessories can be added (included only in some packs): Heightening kit, Rotary module, Engraving Material Pack.
