BenJackson wrote:As I mentioned that sounds comparable (75IPS) to the low-end Epilog. What is your acceleration profile? You need enough overscan on each side (0.5 * v^2 / a) to hit top speed before the engraving starts, so 2m/s is only useful if you are able to use accelerations of something like 200,000mm/s/s. That would mean you could hit full speed in 10mm. That's 20 g's.

Greolt wrote:Acceleration was about 20,000mm/sec/sec or 2Gs. How much is my acceleration distance at that?
Greolt wrote:But would not the limitation be how fast the laser can turn on and off?
