This thing is great as long as you get the Lightburn (or other software) settings right. The settings come with device on a printed sheet.Tip - It doesn't do as well with tumblers that aren't the same circumference top to bottom. This is the majority of tumblers. You can easily make yourself a jig in Lightburn. Take the outer circumference of the top of tumbler and create a circle the same size in Lightburn. Then take the outer circumference of the bottom of the tumbler and center this circle inside the other in Lightburn. Then cut this out of plywood. You will get a ring to put around the bottom of the tumbler to hold it parallel to the laser. Put this ring on before putting it on the rotary. Sometimes a little tape (duct, gorilla) will give extra assurance that it stays in place.

I first tried some of those cheap stainless tumblers from amazon that have a tapered and even slightly curved shape to them. Once I figured out that you had to change the GRBL setting $101=50.381 when using this thing, it actually worked pretty well.One trick I figured out is - tumblers like those I mentioned, on a roller like this one, it might help to wrap several layers of painters tape at the very end of the roller where you don't want the cup to move from when rotating, as well as putting something to keep it from moving the other direction (I literally used a heavy flashlight). This keeps what you're engraving positioned correctly on the X-axis and you're likely to get much better results.As a starter roller, with some fiddling to get things level to the laser head, this is a really nice device.

Outstanding price and performance

OK. So when it says 99% compatible. If definitely does not mean compatible with Full Spectrum laser. Their P series engravers take a cannon plug insert that is definitely incompatible with the Longer friction roller.It came as ordered & was pretty nice but needs an accessory to connect their plugs to a cannon plug insert.

It works it's not the best I would definitely recommend a chuck rotary to anybody looking to get into this.

I made a picture of my grandpa on his old Harley and I swear you can see the chrome shine. Follow me for more reviews to come… thank you I love mine.
