T2 Engraving / Update picture help
« on: March 05, 2021, 03:58:29 AM »
Hi All,
I would like to update a laser engraving I did some years ago. It was not very good at the time and I was wondering if I could possibly update it ??
I have attached a picture of the work and the 2 pictures I was working with. I was wondering if the pics could be enhanced any way to make it less 'overall brown', I think I mean more contrast/ better definition ?? maybe not, I would like it a bit better looking.
I don't know if you can understand what I mean but I am sure someone will have suggestions to improve this laser burn.
take care and stay safe

@ggallant571, I don't think the original is etched. It looks as if it is a sprayed on paint finish.

@Zax, I have a friend that customises motor cycles and he suggests masking tape and a couple of fine coats of paint. I will do another trial  etch through masking tape and hand it to him to work his magic. If he is satisfied I know what to do.

This whole project has been a nightmare due to the fact I received the wrong information and material to start with.
Thanks again for the help

Thanks chaps,
I have finally caught up.
It is a piece of reconstituted slate (slate dust and resin) and does not etch like slate. It melts the top few thou of the stuff and then it solidifies again.
I have attached a picture of the front where he wants the etching to be placed and he has announced that he would like it to be white ?? the same as the picture.
Any ideas on painting it white 'like the picture' ?? I tried yesterday to etch through a covering of masking tape and painted it white and it worked fairly well but the acrylic paint seeped under the tape in places and looked horrific when I peeled it off.
Thanks for the help chaps.
take care

Thanks George,
The man is coming to see the results today. It is no fault of mine that this has not worked too well The material is NOT slate, it is reconstituted slate i.e. a mix of ground slate and resin. He can decide if he wants the results as is or take the piece away.
Strangely enough I had a call from someone, just this week, asking if I would etch a piece of slate with a Celtic Cross ??. I told them about the difference between the slate options and have not heard back from them.
Thanks for the offer to look at the setups, I think the piece is 380 x 255 with a picture on it and the etching needs to be restricted to a space at the top and the bottom. I run the raster twice and then the vector to make sure it's tidy, not sure that's the best way to do it.
Thanks again

I have finished trying what I can for the moment. I don't seem to be getting anywhere with this. I have attached the last 2 pics of what I have done. Pic_03 is the various results from an outline burn and various number of raster passes and Pic_05 is the result of trying to paint the design with white acrylic paint. I will give it a rest for now as I don't seem to be getting anywhere with this project.
Thanks for looking.
take care

Fantastic job. Wish I could do that.

Thanks George,
I have completely lost the plot and and have been too long away from the engraver.
I did this etch yesterday and it cut pretty deep but not what I wanted. I will have another go today (after advice from Zax) and will get it right.
take care

EDIT Pic_3 I have a vector outline that gives a nice neat outline and looks deep, I then enable Sketch (Filled) with a 0.2  gap in the Advanced Menu. and have run 2 passes in raster. This is what it looks like. This is the reverse of the slate so I have plenty room to trial my efforts. It doesn't seem to be very deep, just rough ?? and I would like to see it lighter coloured to match the picture on the front.
EDIT 2 I think the slate may not be slate as I think it is melting the stuff. It cuts a fine vector line deep enough but then when I raster it it seems to melt ??

I am trying to etch a piece of slate and it cuts a groove fairly deep. It doesn't show a white etch like I see on this site with pictures from the regular engravers

+1 for what ggallant571 said. Fairly simple to do but you will need some engineering knowledge (or just ask ).

Welcome Dean,
You are in the right place to have your setup verified. The guys (and gals) on here have given me their time and experience  many times and I am very happy with the results I have achieved so far.
Your setup bears a resemblance to mine but since I started I fitted Home switches and a gantry arrangement to clear  various wires out of the way and a tray (from the oven) I use as a jig for repeatability.
I'm sure there will be someone along soon to set you on the right road.
take care

Thanks Zax,
I will start here this morning and see what I can do.
I'm back. I tried the pics today and this is what I got on Birch laserply. Not sure if this is the best that can be done. I did try various speeds and found that the couple was best @850 mm/min and the group was best at 800. Maybe I could tweak somewhere else.

I have 2 pictures I would like to try and had a look at them today. I loaded them into T2 and both files were quite big, in fact I did one at 0.1 resolution and the programme asked me if I wanted to do that ?? Is there a simple way to etch these ??
Any help on how to start this is welcome.
