Hi Gang, anyone around?
My Epilog gives me a darker mark in stainless than the rabbit.
Epilog is about 11 years old and 25 watt.
Rabbit is 6 months old and 80 watt.
Epilog is at 300 dpi, Rabbit at 600 dpi.

Dan,
So Brian's problem would be a function of the lens optic and the beam quality (size and shape) from the tube? I assume a better lens would help possibly, and far more expensively a different manufacturer of tube?
Hope you are doing great Dan!!

900x600 80watt EFR Tube laser from Liaocheng Ray Fine Tech LTD. Also a 900x600 2.5kw spindle CNC from Ray Fine. And my main tool, a well used and loved Jet 1642 Woodlathe with an outboard toolrest that helps me work from 36 inch diameters down to reallllllly tiny stuff.
In a nutshell, yes... though to be honest, I didn't expect such a marked difference in power density between a 25W RF and an 80W DC. It sounds like there's room for improvement with the DC setup.

Lots of room Dan, rise times on Chinese DC is terrible, pulse rate isn't much better as standard. Get into the SLC and suchlike from GSI though and they easily outperform most of the western RF units but at £20,000 for a 200 watt unit they damwell should
On a profiler the difference between RF and Chinese DC is worlds apart, RF are much closer to single mode where are even the better RECI etc DC tubes are are multimode
It pretty much works out that a 40 watt good RF will outperform an average Chinese 80 watt easily.
cheers
Dave
You did what !
Thanks Dave!
That was interesting, and adds more thoughts to ponder on while I wait to buy something.
Actually, I should be cussing you for adding more thoughts to ponder!!! <friendly grin>

I included mode in my "focal ability" answer (well, in my mind I did ), but I hadn't considered pulse rate for this. I simply figured without a TEM00 beam (DC tube), the ability to get a sharp focal point (i.e., high power density) was severely reduced. Still, at 80W I would have figured on the sheer raw power would be enough to heat the area enough, the "pixel" would merely be oversized/blurry.
