2Nd Mirror Alignment; 3Rd Mirror Alignment; Lubrication - Omtech PRO 2440 User Manual

6.4.3 2nd Mirror Alignment

After ensuring the laser is well aligned between the 1st and 2nd mirrors, check the alignment between the 2nd and
3rd mirrors. Repeat the steps and adjustments above, taking care to use the tape on the mirror's frame and not its
surface.

6.4.4 3rd Mirror Alignment

After ensuring the laser is well aligned between the 2nd and 3rd mirrors, check the alignment between the 3rd mirror
and the workbed.
1. Place a piece of tape across the bottom of the laser head and press it onto the nozzle with some force. This will
leave a ring mark that can help you check the accuracy.
2. Tap to fire the laser. If the laser is not centered through the laser head, adjust the 3rd mirror's set screws accordingly
as above. Test again until the beam is well aligned and retighten the nuts on the set screws.
When the laser is well centered along the entire path from the tube to the workbed, your laser mirrors are all correctly
calibrated and (assuming they are clean) performing at optimum efficiency.

6.4.5 Lubrication

For best results, clean and lubricate the engraver's guide rails every two weeks. Turn off the laser engraver. Gently
move the laser head out of the way. Wipe away all dust and debris along the X and Y axis rails with a dry cotton
cloth until they are shiny and clean. Do the same with the Z axis screws reached from the bottom left access door.
Lubricate both the rails and screws with white lithium grease. Gently move the laser head and X axis to distribute
the lubricant evenly along the rails and raise and lower the bed to distribute the lubricant evenly along the screws.
