Thanks for alll your replies, i was too afraid to brush the burn out just in case it ruined my image but after reading your comments i gave it a try and it worked great... Thanks guys..
As far as a fan on my machine - no i don't.. Do i need one.? Do they help.?
YES AND YES...
A fan also stops the lens being dirtied up...and if the machine is in an enclosure you will need an exhaust fan as well...and if you cut stuff that gives off toxic fumes then you need and enclosure AND a good exhaust fan to exhaust OUTSIDE.
Fair bit of info on the forum about air ducting onto the work piece and ventilation.
