so an update and my review after installing the lasertree 20W verses the seinci 7W. Installation was simple just need a connector to connect the PWM wire from slb to lasertree driver board. I mounted the laser to the mounting plate (just had to drill 2 holes) that came with the seinci laser, I also had the magnetic laser mount from sienci so it is very easy to put laser on and off.
I have the longmill 48 x 30 with slb.
Cutting with the seinci laser is not a viable option whereas the lasertree cuts very well and cleanly. You do need air assist and speed during the cut is essential. I cut 1/8inch birch ply at 6000mm/min in 1 pass, also did 1/4 maple ply in 2 passes at 6000mm/min. So in this category there really is no comparison.
Engraving. Seinci laser engraves quite well. Testing on cherry lumber doing a line engraving and text I get good results on dip 4, 30% @ 1500mm/min with g2 lense. Laser tree gave a better end result @ 6000mm/min and 10% this is probable due to a smaller dot size though I have not checked. The upside apart from better quality engrave is the increase in speed.
Photo engraving for seinci laser I get excellent results with 3e lense, dip 4, 100% power @3500mm/min. Tested atkinson, newsprint, dither, and jarvis all were very sharp between 70 and 100% power with best results @100%. Laser tree was nowhere close with a speed of 6000mm/min and max power of 5%. The issue being color gradient due to having to set the power so low. If speed could be increased more of the range of power of the lasertree could be utilised which would give more color variation.
In conclusion if you want to use a laser to cut go with the lasertree but if engraving especially photos the the seinci wins hands down though I suspect that the lasertree 10W would be a better option for the longmill and the 20W if you have the altmill.
