Re: How to cut silicone liner paper multiple sheets

a vacuum environment will help but as yet I've never had any real success cutting multiple non metal sheet materials that aren't bonded together. One method that does give *some* result is using spray mount on the layers to remove any air gaps between them but even that isn't great.

Re: The problem of Mdf material cutter !

6mm MDF you will probably want to cut at the highest speed and lowest power that you can. Not sure what the bottom-out power on a 2.2kW resonator is, but probably extremely over-powered for MDF.

Re: Reviews on Argus laser machines?

Quite possibly this is the best small machine made in China at the moment.

Laser power decreases after some minute

Something strange happen in my laser cutting machine.
I have a 150w laser tube, it works fine but after some minutes of cutting at any power, it seems to lose about 30% of power, so I need to reduce speed or increase the power.
Someone experimented that? any suggestion?
Hope this is the right section
