Seems like all I can get is Brown and White with grey scale my second day with the laser
Photo edited in LB (hd photo phone makes it look horrible)
I tried burning a greyscale i found on here and all i produced was deep brown cut where black should be and over half of it not burned at all.
5.5 diode laser sainsmart
Power 60%
Min power 7%
Speed 900 mm/m
250 DPI
Which version of GRBL, and are you using “laser mode”? ($32=1) If not, grayscale will be impossible because the controller will pause constantly.
What kind of wood?
I would suggest going faster (try 1800 mm/min) and increasing the power to 80% or so, which might help. Grayscale is harder to dial in, dithering will give you better shading with less effort.
Grayscale will take some tuning to find parameters that work. I recommend starting with a simple gradient and running small samples with different settings to see what gives you the best results, then move up to pictures.
I started that last night on a paint stirstick. With no luck but ill give your settings a try!!
What should min power be set to?
For a diode, 0 to 2%, likely. Different woods react differently to lasers, so the settings you arrive at for a paint stick will work perfectly on more paint sticks, and little else. 
Test with the wood you plan to use. Basswood and alder work really well, as does maple. Birch is decent, and cheap.
Thank you tons! I bought your camera too. You guys have great support and sure i could go on Amazon and order something cheap but bc of your support i want to support you! Thank you again!
