Engraving on cotton

Postby Willy Ivy » Thu Nov 17, 2016 8:07 pm

Keith mentioned something about opening another thread on engraving I think on cotton.
I got out my old practice jeans and t shirt because I needed to know this myself as my first machine burnt up and I have not tried with this one yet.
Besides I have spent many more hours working on the second machine than I have using it. Back to the drawing board with all my projects.
Anyway this is what my machine looks like it would be till I get more time to play. Speed of 300 and power of 20%.
Numbers below the engravings are speed and power.

Yes Willy, It really depends on how heavy the material is. The trick is to burn as much as possible but NOT through the material.
That is a nice sample board for one to choose from.
Mine ended up as 13% @ 450 with the medium thick Apron from Michaels. I had a small cut at 14% @ 400

Well, I washed and dried the Apron that was engraved. This is the result.
Guess I am like the people that try to register using a name like Joey45Kicker.
I never read the instructions - "DO NOT MACHINE DRY" !
Huge shrinkage and all the engraving fell out. Not sure if it was the engraving or the washing or the drying, but an Apron MUST be washable! Will try on the other two and see what the result is.

Yeah that's what my tshirt looked like also the first time I wiped something with it after lasering it with 18 & 20%. 15% ok but more tweeking on mirrors and square will probably make that percentage lower again.
Now that wedding #1 is done, trying to get all bugs out of this laser and relearn this one.
Notice I installed v8.01.18, did not see .19
