New machine on the way

[PAULRO]

Hi Al, that's impressive,
my son has signed up to buy a glowforge ( a waste of time and money i think)i'm hoping to change his mind so i'm researching options for him. he has a fledgling architectural company started and wanted a laser for model building. i finished a course in cnc/laser cutting sometime back and can see the potential for model building. the course did not include any maintenance or optics setup so i'm wondering is it much of hassle? any info would be greatly appreciated. also is there a chiller required for the tube. and if so , is it supplied? i seem to remember a water chiller to cool the laser tube on the course i did ( trotec laser, lasersaur laser) . i heard that a air jet is also required to stop the material from catching fire, is this true? i spoke to a laser owner near me and he uses an air jet on the material being cut to prevent fire. last but not least , is there an extraction method for the fume supplied? sorry for all the questions but i'm trying to get as much info about the machine you bought because it looks a bargain and i am putting together a costing to convince my son.
