Have a read through this post which may be of help to you, finishing plays a major part with these from what I have read on the forum. Don't expect to get great results just by using someone elses settings, there are far to many factors that play a part. Try a small test area & be prepared to tweak the settings a bit to get the best results on your own machine :lol: :lol:

opps, helps if you post the link :oops: :oops:

MikeJohn,

Also, you need to resize your pic and not use this one as this is a low resolution photo. You need a high resolution photo to begin with for it to come out a lot nicer than what I had to work with.

I'm a long way short of being an expert as I have never been able to get good results with Photovcarve (keep meaning to try again) but it would be a good idea for you to post what you intend to use as a substrate for cutting.
The advice you get if this is to be machined in wood may well be different to advice given if this is to be a lithophane machined from something like corian :lol: :lol:

As Tony has said you need to start with a high resolution image, BMP or Tiff is better than Jpeg if you can find one :lol:

Thanks folks. I did not think that it could be a lithophane. Sorry about that. But someone might enjoy trying it as a lithophane.

I was going to cut it in timber. I have no idea what timber yet. Lots of folks in the US use maple, but our maple is different in Australia.

I did a try using the trial software, so it has watermarks in it somewhere but here is my try - see pic. It is just cut on some scrap marine hardwood plywood.

I did it at 0.08 deep. 120%. 90 degree vbit. 33% line angle.

I just roughly painted it and sanded the surface for the trial.

How do I improve it?

I re-sampled the image to 300 dpi in gimp.

That is not too bad of a first attempt. Now to get all the paint off :lol: After cutting did you use some sort of finish before painting? I like using water base paints. After I put it on I immediately wipe off excess so I can reduce the sanding needed. Sometimes I can get almost all the excess of without sanding, others I give a 2nd coat to. but rather do this then sand it all away.

What sort of finish do you use before painting?

some use shellac, some use a coat or two of poly. It stops the paint from bleeding, that's one reason I use water base paint.

What I don't quite understand is, do you use water based poly with the water based paint? Would not the water based paint be a problem on the oil based poly otherwise?

Thanks

I think I should be more specific.

I have this poly http://www.feastwatson.com.au/consumer/ ... tails/1512

and this stain http://www.feastwatson.com.au/consumer/ ... tails/1520

I just can't see how I seal with poly and then stain with these. I doubt the stain will do well on the poly.

Should I just toss these aside and go waterbased with poly and stain or paint?
