First large engrave project: Harry potter fans

I have been very intimidated by the learning curve involved the cnc shark process. I have had my unit for a little over a year and finally dove into a large project for my grand daughter, who is a Harry Potter enthusiast. I have learned a lot from this project. It is 36in x 22in made of pine. Next time I will try a hard wood, the sanding of the soft fibers in the pine is an unending task. but my grand daughter will love this on her wall in her soon to be done Harry Potter themed bedroom, a birthday surprise.

Nice job, it looks great. For your next one, you might experiment with creating a V-carve path and using a V bit to see if you like that effect, too. It would be perfect for a design like this.

I have a smaller scale one to do. About a quarter of the size. I will give your suggestion a try.

That's a really nice project. Thanks for sharing. While I don't work with pine, I do work with other softwoods at times. There is a different in outcome using a down cut vs up cut end mill and the amount of sanding. IDK if you were using a down cut or not, but you might try that in the future to see if it helps you.

I was using a tapered spiral ball nose 1/16th diameter

Ok - but I assume you are using a pocket toolpath for some/all of this?

I did a profile for the perimeter and an engrave for the meat of the project

Well it worked for you and in the end that's all that matters. It seems like a lot of material and run time using a 1/16 BN. Another approach might've been a pocket toolpath - and use a clearance tool as well. Endmill use might've cut down on some of the sanding. Thanks for sharing the project!
