I'm not downgrading for anybody Keith
You did what !
Dave,
I wish a Kern Laser was a downgrade for my shop
I really love my Trotec but It would be awesome to be able to vector cut steel sheet, half inch thick Corian and glass..........

Steel's ok to do Keith but the cost runs compared to organics are crazy, a LOT more competition as well from mid industrial shops. A lot of end buyers don't quite grasp if you are pumping £27 worth of oxygen or Argon through the nozzle per hour then their job isn't going to cost £15 per hour
Must admit though, stainless is a giggle when you start making the smaller items that have always been made of wood out of steel
best wishes
Dave
ps: Matt...ummm NO
You did what !
Matt, you're saying you have different focal lengths for 300dpi vs. 600dpi? Is this because of the machine you're using? I operate a Kern Micro (150W) and a Kern100
I'm not familiar with this setting recommendation.
No, we just have a 2.5" lens. It looks like the beam spot (or its effective size) from our laser is less than 1/(300dpi) ~= 0.003 in wide, because if I engrave wood at 300dpi I can see ridges left between passes. There isn't anything in the settings sheet about this—it's just something I've had to figure out myself. The beam width and quality (both determine the focal spot size) for our 400W laser is likely different than yours.
