Thanks Bob, I'll give that a shot on Sunday. I was thinking I should have the letters solid white for a clean transition between the background & the letters. I thought that if I had any gradiation, that it would come out looking like they did....
Medium is too fast for the letters you are doing I know how long slow takes but the speed the bit aproaches the edge of the letter is too fast and gives a bad cut. You can either endure the time or use the gradient to aid the transition.
Irestore; In my experience so far and using letters that have a gradient in them I always carve on the "normal" setting which I equate to medium speed. As long as your lettering has the slope , which gradually tapers down the letters don't really tear out, only when you are carving basically straight up and straight down letters seem to tear out on medium speed plus they are a bit fragile standing up straight out of the wood. I have attached these letters I just made using MS Paint and GIMP. Went to paint and made the lettering in size 72 with black background and saved the file. Open same file in GIMP and chose select all, then chose under filters Gaussian Blur which I gave a value of 10 and chose OK. Exported out of GIMP to my saved files as a .PNG file. When you open this, zoom in real close and you will be able to see the slope that is on the lettering.
I was working on a mother's day gift all weekend & didn't get to the test cut, will try it soon, but am confussed on which speed to use.
I was talking about when you use a gradient on the letters like Bob is showing you, that shoould fix your problem. The only way to use the letters the way you have them now is to make them much bigger and go slow, using the blur will give your letters a little more strength
Do you have a copy of the Gimp? if not get it and install it. The Gimp is free and is the next best thing to photoshop a lot of people feel its better because of all the free add ons, you can waste hours just playing with it, changing colors of grey will give you higher cuts for light colors and lower cuts with darker ones. The reason you want to blur the picture is the Cnc machine will make a smooth transition from one color to the next.
Granted sometimes you will want a sharp cut and you kinda get a feel for what it takes to do that with experience and wasted cuts.
Wasted cuts are not a total loss since you learn from it each time, I have had mine for about 8 months now and I can tell what my cut will look like before I make the cut and I just go put it in and let it go with no uh oh's but I cleaned out my whole shed's saved lumber before I got to that point. LOL
I've had my machine since last August and while using the supplied images worked real well when I wanted to do some different things I made what ended up as fire wood. All trial and error but eventually it will come to you, like turning on a light switch then you will be up and running with it.
no issues at all it moves in a diagonal direction just as planned and its made me some nice photo's. They have a free version with water marks for you to try out. I bought cut2d with it as a package for 249 and I use it with the slow setting and multiple passes so I don't overload the bit with the Y axis speed.
Ok, so this darn thing called "work" has been getting in my may lately & cutting into my woodworking time.....
Anyway, I am back & learning to use my machine again. I used a provided image CT-F021-0A.Frame to create the following carving. Notice in the close up pictures at the edges where the cuts weren't uniform. Any ideas on what would cause that? I didn't manipulate the picture at all.
