I'm running a 6-year old epilog 35-watt mini and need to do some volume etching and cutting of 3/16" acrylic. Layed out my first test sheets, using the full bed size of 12x18. Etching ran fine, finishing in about 15 minutes, then it went into cutting mode (speed 4/power100/5Kmhz). Ran another 25 minutes, about 3/4 of the way through the job and shut down...Oops? Didn't reset for at least 1-hour, so I came back in the am and rebooted OK.
Epilog tech was helpful in identifying probable cause of shut-down as power source over-heating. Sounded right as both power supply and tube were hot, but not excessively so. They suggested adding more air flow the area to reduce the problem.
My questions to the Forum:
- Does it sound right that system would overheat after what I think is so short a run? Are my expectations wrong?
- Should I lower power and make 2 passes to reduce power output on system?
- Anyone have suggestions on running air flow into tube area to keep temp down?
- Other ideas are always welcome.
Thanks.
