Pinnacle m series

[kycolt]

I found someone who is selling a Pinnacle m series 25 watt laser. According to this person, he paid close to $17k about 5 yrs ago. He has a lot of extras with it. He has used it very little he says. His price is $6800 or best offer. Can anyone give me any advise concerning this laser?

Hello,
Ask seller about following:
WHEN this laser was manufactured?
Type of tube? Is it Synrad or other (during short time this laser was manufactured also with Coherent tube which is NOT OK)
Mirrors and lens? New or old? If old - could you with powermeter (special device to measure laser power - must have laser equipment dealer, possible rent it) measure power
AFTER LASER
AFTER 1 MIRROR
AFTER 2, 3, 4 MIRRORS
AFTER LENS - ON TABLE
In this case you will have clear view of HOW MUCH POWER YOU HAVE and is it enough to work your materials.

Ask pictures of VECTOR TABLE and ENGRAVING HEAD.
Ask about autofocus - is it working or not?

Is this model with USB port?
Be ready that even NOW everything is OK with tube - you will need refill in next 2-3 years.
