My 1390 Triumph came with PHCad and PHSoft laser software, which from what I've seen from screenshots is just re-badged "Laserworks". FWIW the PHsoft is a newer version that never works right...but that's another story.
Anyway- the machine and software came loaded up with a max Y-axis speed of 300mm/second and X-axis max of 500mm/second. I found out that I can speed things up by changing the machine parameters in the software. So far all I've done is moved the X-axis speed to a max of 700mm/second. I've tweaked the backlash at that speed and I get nice rastering results. The only negative I've noticed is the increase in the left and right edge overrun. At 700mm/sec it's more than an inch- no problem as long as I keep what I'm engraving farther than the overrun distance (or I get "not enough space" on the machine readout)
I'm curious as to the ACTUAL max speed this machine will go. Haven't had much time to experiment further.
I'm also curious if others have sped up their machines, and how much?
