This is the test I run on every new wood species and often on several to test what I want to actually use. but this first test runs the engraves at twice the number noted and then comes back and makes the cuts at the numbers noted and then cuts off the piece at two passes at 125 all full power.
Watching closely while it is done allows me to put a wet cloth on after it cuts in the case where it starts to make charcoal,this is the Zebrawood piece after sanding it as the cut is deeper and burns more where it hits previously cut places (in any case, not just this wood)…
I ran another test on an unknown wood I suspected was Zebrawood but I re-arranged the cut sequence to do the engrave first and then the cut for each different setting and doing the final cut before the last two. in this way, there was less time for the charcoals to burn,
It was zebra wood and it cut through with two passes at 125 for a 0.275" piece
Of perhaps more interest by cutting across the engraves first, it hardened the wood on each side and the engrave only cut 1/3 of the total distance for fresh wood!
This could be why multiple passes are not as effective at cutting as the first pass.
