Purchased a used china laser some 7-8 years ago and been on that "learning curve" every sense!
Got the unit, a 60 watt china model with a 12x20 bed. Done a lot of "upgrades" to it in the last few years, new AWC708c controller, HV power supply,tube,hour meter and the like.
Reason for getting a laser was to add to my life long hobby, R/C aircraft, and cut parts for new models and repairs
I am now over 70yrs young and still looking for ways to make the machine better all the time and hopefully glean some new knowledge from other peoples experience with their lasers. Seems one never stops learning about these things!
We live in southeastern Ohio in a rural area and enjoy this area very much.
