I hope everyone is doing great!
I'm trying to get some lamacoid (aka lamicoid or engraving stock) to properly engrave. I have bought some trotec engraving stock (almost $100 a sheet) but I am not getting any good results. I have a 90W Chinese laser. I'm trying with approx. 300mm/s speed and 15-20% power.
The problem I am having is that the dust that is being produced from the engraving is contaminating what has already been engraved and cannot be easily wiped or cleaned. Here are some of the things I have tried:
1. I have tried engraving from bottom to top (as apposed to from top to bottom) so that the suction takes the dust away from the already-engraved surface, but that did not help much.
2. I have tried doing a couple of passes of lower power (as apposed to one pass) to take care of the contamination. That seemed to help a little but I still need to scrub the sign afterwards.
3. I have tried a lot of different cleaning materials to scrub the contamination off, but that doesn't bring out the crisp back color. It is also not feasible to clean each sign made.
P.S. I have tried a few different color combinations and the problem is persistent (I have tried silver on black, black on white and blue on white).
P.S. This engraving stock is made to be lasered (not the CNC stuff).
What do you guys think of this problem? has anyone faced the same issue?
Thanks in advance!!
