Summary

My son requested a red puzzle from Santa this year. His favorite color is red and he loves hearts, so this was our solution. 
The engravings are deep with a speed of 50 and power level of 70. 
The cuts were the default M1 3mm basswood cut settings. 
This was a combination of my design and a puzzle file from Mr. Richard found here: https://projects.xtool.com/howtos/1737

Mr. Richard, you do great work sir. Thank you for sharing and inspiring us all.
