My first practice carve

This is the first thing I have put together and carved out. Not much thought went into it other than trying not to break anything. I wanted to do something that used multiple bits, tool paths, and…

I used:
60* 1/2in Vbit on the stars, the lettering, and the emblem. I think the feed was 40in/min plunge 15/min - stepover .06 - stepdown .1 - rpm 15000

1/8 flat endmill on the stripes (pocket) and the circle (profile) I think the feeds and setting were about the same. I’ll have to look at my laptop later to see.

After using the probe and hitting start, the router went straight to the first star (bottom left) and burrowed into the wood and spoil board. Don’t know what I did wrong there. Then I used some paper to reset zero at the bottom left corner and hit start again. This time it went to the same spot but was acting like it was carving the star. It went on to carve the rest just fine. Well, I say fine but I really don’t know what that Is yet. There was some light sanding along the edges of the cuts that needed to be done and the center of the stars looks messy.

I changed the bit and started the stripes. First I did a profile of the stripes with a 1/8. I was planning on clearing what was left with a 1/4 but I forgot and just did the whole thing with the 1/8.

Can anyone think of anything I should have done instead? Is there a better way to do the lettering where the tool marks from the point are not so pronounced? Maybe a smaller stepover…IDK…?

@Swinly What cam software are you using to create your toolpaths?

Carveco Maker and using UGS

The piece is 12x21in I will most likely in a day or two flip it over, stain it and do another one to see how it turns out.

@Swinly It’s nice work, despite the glitch. I can’t help you with Carveco. Others here use it and can likely reply to your questions. In VCarve, stepover is not used for V bits as you are not using them to clear out pockets or do 3D carving, where stepover determines how clean things are. The depth of the carve is determined by the distance between the lines that you are carving between. That is if you are using a vcarve toolpath. You can use a v bit and a profile toolpath, in which case, you set the max depth and the number of passes to get there. I suspect it’s a bit different process in Carveco, judging from previous threads.

I can tell you that I have found that it frequently results in cleaner v bit carving by running the same toolpath a second time. Mark Lindsay, on his Youtube channel put me onto this and I find it does work.

When I setup the toolpaths I did it in sections to simulate a larger project with many different paths. During a pretend bit change I forgot to load a new toolpath and ran the same circle profile cut a second time. It didn’t register with me until you mentioned it but it did make difference.

I think it turned out great for the first one and the tool marks gives it character

Thanks

Well I flipped it over, stained, and went at it again for a bit this evening. Lesson for the day is to make sure that the clamps I do use are actually tightened down. Shortly after I hit start the board spun free.

Ahh yes, the Joys of CNC…wait until you hit a metal screw or clamp, or break a bit (especially that slightly expensive 1/32 bit to do a specific job), or forget to put the magnet on your collet when using the probe - talk about scaring the crap out of you…now where is that stop button…Carve looks fantastic, by the way.
