Rollers are not locked, brackets are
wobbling
Adjust the eccentric nut under the
bracket, lock the eccentric nut so that
the bracket does not wobble.
The laser stand extends too much
that causes the laser to shake.
Raise the laser to let it as close to the
top as possible to reduce laser wobble
When the engraving picture is small,
the line is not straight
You should slow down the engraving
speed, this will reduce the laser
shaking
