Hello all engravers, I am at my wits end with this horrible problem that my department has been working around for months.
First off, we have 7 Epilog Laser Helix machines, all 50W, all relatively new (under 6 months), only 2 of them can print thick filled logos.
The other 5 machines seem to produce striped results like so:

The only way we've worked around it is by using the Auto-Focus feature, adjusting the focus to -80 and -90 and running at a very high speed of 50-55.
Now all the techs at Epilog highly suggest not using the Auto-Focus feature and urge us to use the Manual Focus Gauge, however when we do this, our results come out either streaky or bronze/golden instead of solid and black.
Epilog has had us do many many tests but to no avail. These tests include aligning the laser, tightening our optics, engraving at low dpis and high dpis, checking the resolution on our CorelDraw and matching it with the dpi on the machine, lowering speeds, manually focusing and manually adjusting the focus up or down, switching rotary attachments.
We've also tried printing a 1inx1in block at 75dpi on a piece of acrylic to compare it to the lasers that the techs are using. They haven't gotten back to us about any solutions unfortunately.
The engineer that works with our company has checked the voltage to make sure they are all pumping out 220-240. He has also checked the fans and other mechanical aspects of the machine such as bearings, railings, belts, etc.
Has anyone else run into problems like this?? It seriously feels like our company is the only company in the world that has these issues seeing as I can't find anything closely related to this.
Any help would be very much appreciated. We are suffering at the moment seeing as we have a large order with a rather thick logo that can only be printed on 2 of our machines.
