Enter as much information about your CNC hardware and software as you can - it makes it easier for everyone to know what you're talking about then.
These PDFs show how to replace the mirrors on the versalaser.

TIP - keep these mirrors clean at all times using the provided cleaning fluid and 'cotton buds'
If dust and smoke build up, then the mirrors get hot, burn and even crack

Replacing the mirror is straight forward. However, if there is no magnetic attraction it is not being held securely. Why should the mirror be demagetised? Can we have a new one please?

Please note:

There is heat build up in the mirrors and lens when the laser is being used.

If the mirror or lens are marked with smoke or material that has been cut then the heat build up increases and can burn or crack the optics.

Never clean the optics shortly after running the laser :!: :!:

If you put cleaning fluid on a hot lens or mirror it will crack or craze :(

It is best to clean the optics when the machine has not been used for at least 30 minutes.

If the optics apear to be clean leave them alone :!:

When cleaning with a cotton bud just roll the bud over the optic once. Do not use the bud more than this as you could scratch the surface with particals that have been picked up.

I have learnt all this from experience and cotton buds are a lot cheaper than a new mirror or lens :oops:
