Polywood , Auggie and sugar
Posted: Thu Feb 11, 2021 11:00 am
Hello everyone .
As i say in some post , engraving on polywood it is realy tricky.
Why that ... couple of things i notice during time .
Well , ploywood is very different , i mean what you engrave today on same type
of wood will dont work tomorrow with the same settings.
I notice wood react so different on different moisture .
I keep my , on a chamber where the RH is strict controlled (is tobbaco chamber) but even like that
will dont work all time the same . Maybe you need couple of try until you got a good ressult.
Trying to find a good sollution , i mean something "stable" that didn't work. Depend to much where the wood grow ,
wet or dry place ,chemical soil components and many other things can made it " non standard type"
So .. looking when my wife made kookies i realise the sugar keep it in high temperature
will change the collor in " linear " way , or... almost .
I say to made a test , i put some sugar in boiling wather and after cool down i apply on polywood
surface with a brush . I clean with " absorbant paper " i dont know the word in english
and i let it dry for 30 min.
And i start to engrave some old photo.
Well the result wasn't to bad , because the photo was made with my phone
from a " paper photo " and after engraved.
And i made two test on different type of polywood , that normaly need 2 totaly
different power , speed ...
They come almost the same .
Now i let a piece of polywood on very dry place and i will made a test with sugar
after is very dry to see if will be any difference . I notice when the polywood is very dry
to get the black level the laser will go to deep. Make sense anyway.
I will post here soon the polywood will be dry.
.....edit later...
The white dots on small picture are normal, the picture was made when snowing agressive .
Thanks
Bobby
