Where to get help with alignment!


One of the most important maintenance skills is alignment.

Alignment is the process of ensuring that your tube mounts, all your mirrors and your focusing lens align to give you optimal beam strength and focus. If the beam is badly aligned your laser cutter might not be able to cut through material cleanly, might be underpowered or might have uneven angles in the kerf (the removed material) at the edges of your cuts.

First do a quick alignment test like in this video:

You can run a similar test to check the downward alignment through your focusing lens.

and for comedy rather than for help this video animation with a computerised voiceover, the graphics are helpful to illustrate what’s going on in your machine… sort of the machine with no box around it. Video by Alex Meng.
