Pull the holding clamp towards you, place your material between it and its frame, and release the clamp to hold
your material in place at the correct height.
Be aware that using the deeper bed and clamp limits your engraver's processing area to 8 inches by 5 inches
(200×125 mm).
Step 5. Close the cover. Turn on your control computer, open LaserDRW, and create or load your design. Make sure
the "Out to File" box is unchecked.
If this box is selected, the program will save your file instead of engraving it.
Step 6. Pull up the emergency stop button and flip the power switch to ON. Turn on your laser tube by pressing the
Laser ON/OFF button. To reduce the risk of electric shock, once the laser tube is on, try to to touch the
engraver with only one hand at a time. Check that all temperatures are at acceptable levels (see §3.4). Select
Engrave on the main toolbar and Engrave in the drop-down menu. The laser head should reset to its origin.
Step 7. Adjust the placement of your design to match your material. In LaserDRW, the origin is shown as the center
of the blue cross formed by the X and Y axes.
