Laser Path Alignment - Omtech USB3020A User Manual

5.3 Laser Path Alignment

Having a proper beam alignment is important for the machine's overall efficiency and the quality of its work. This
machine went through a complete beam alignment before shipping. When the engraver first arrives and about once a
week during normal operation, however, it is recommended that users confirm that alignment is still at acceptible
levels and that the mirrors and focus lens have not shifted due to movement of the machine.

You will need to place a piece of tape at each stage of the laser path, marking it to confirm that that stage remains
correctly aligned. When it is not, you will use the laser tube's brackets or the screws on the back of the misaligned
mirror to correct the problem. Once the provided tape runs out, we recommend masking tape as it is easy to manage
and use.
Performing a beam alignment can expose the operator to small amounts of radiation if performed carelessly.
Please follow these procedures correctly and always take caution when performing a beam alignment.
Perform a beam alignment at low power levels. 8 mA or 11% should be sufficient to leave a clear mark without
igniting the testing tape.
