Can anyone help me how to install this? 
I installed that on my machine, what’s the issue ? I can help if you tell me what exactly you are having trouble with
I posted my Laser head , i really wanted to know how to attach this stuff on this.
Can you recommend any air assist for this?
There are lots of tapped holes on the mirror and lens holder on your open head design. To mount the traditional head, you need an L bracket with holes on the vertical surface to attach it to the machine and one on the horizontal surface to install the new head. I’m happy with my open head design, so I haven’t converted. I’m sure someone has made a conversion bracket somewhere.
