Summary:

As you engrave, debris such as smoke and dust land on your focal lens, building up a layer of residue over time that absorbs laser beam power and can stain the lens permanently. Eventually, this lost power will affect your machine’s precision and throw off your laser settings. To keep your device running at its full potential, we recommend inspecting and cleaning the optics system once a week and replacing the mirrors or focal lens as soon they get damaged.

How to Select the Proper Focal Length:

A lens with a shorter focal length (1.5"–2.5")  has a smaller focal point to provide sharper details for high-resolution images. A longer focal length (usually up to 4") has a larger focal point and extended depth of focus (or focus tolerance) which is better suited for cutting applications. Also, keep in mind that using longer focal lengths subtract from your workbed’s Z-depth.

absolutely must buy perfect for dogs. I have a large black lab and he has had so much fun with us.
Size: Large Size 3, Color: White-Blue
I have to say that my dog would be considered an aggressive tower. However, this ball has stayed intact. I love that it comes with the pump. It’s extremely functional very soft for catching can be cleaned. Very easy easy the quality is exceptional. Very functional does have a bounce. I can say he has had so much fun with this since it’s getting it for his birthday on 11/11 I highly recommend this product and would definitely buy again.

Perfect for keep-away
Size: Large Size 3, Color: Red-Blue
I purchased one of these for my pup and he has a ball throwing it up in the air and chasing it. Handy for something they can play with alone.

Good toy for dogs
Size: Large Size 3, Color: White-Blue
Bought this for our husky. Thought it would be bigger but it’s a good size for her. She has not managed to tear it apart after having it for a few months.

Puppy proof!
Size: Large Size 3, Color: White-Blue
Purchased the blue ball. Puppy loves to carry and shake the ball with the strapes in her mouth. Lots of bite marks but hasnt popped it. We bought 2. She plays in her fenced in yard with them. Fun to throw and kick around.
