Laser Engraving & Cutting Control System Manual

5.8 Frequently Asked Questions

5.8.1 Processing file can’t be download to the controller

The memory block of the controller might be damaged and it should be formatted.

5.8.2 PLT figure can’t be engraved

The graph is unclosed or overlapped. Please use the ‘Check Data’ tool to check if there are such occasions.

5.8.3 Size of the output of engrave/Cut is not the same with the graphics

Please adjust the ‘Pulse Unit’.

5.8.4 When engraving, the edge is not in order

It is mainly caused by the backlash. You can adjust it like this:

a). Draw a rectangle, set the 0.5mm in ‘Laser Engrave’ and ‘Engrave Step’. Theoretically, the engrave result will be okay,

that is, edges of the odd lines will be in order and edges of the even lines will be in order. But odd lines and even lines MAY

NOT be in order.

b). Open ‘Set Engrave Options’. There are different processing parameters for different speed ranges. But set values in the

‘Backlash’ are all 0 (zero). You can set the value according to the actual situation, both negative and positive.

c). If you require a better engrave result, choose one direction laser on. Un-ticking/un-marking the ‘Bi-Dir’ will do. But this

will decrease the process efficiency.

5.8.5 Axis doesn’t move (TRUCUT CONTROL MOTHERBOARD)

A). Set direct voltage 5V by a multimeter. Measure the voltage between PUL and GND. An example with the Y-AXIS:

Press up or down button. The normal value is about 2.8V. If it is not, the controller is damaged. Please change the

controller. If the normal value is 2.8V, step on.

b). Change the OUTPUT TERMINALS of the two drivers, and press up or down button. If X-axis is right, then the Y-axis

motor is damaged. Please replace Y-axis motor. If X-axis does not move, then Y-axis driver is damaged. Please replace

Y-axis driver.

5.8.6 Axis can only move to one direction (TRUCUT CONTROL MOTHERBOARD)

Set direct voltage 5V by a multimeter. Measure the voltage between DIR and GND. An example with the X-AXIS: Press

the left button, followed by the right one, to see if there are changes in the voltage (higher than 2.8V or lower than 0.8V).

If not, the controller is damaged. Please replace it. If there are changes in the voltage, check if the driver is okay.

5.8.7 Laser always off (TRUCUT CONTROL MOTHERBOARD)

a). Set direct voltage 5V by a multimeter. Test the voltage between LAS and GND. Press ‘Laser’ on the control panel to

see if there are changes in the voltage (higher than 2.8V or lower than 0.8V). If there is no change whatsoever, the
