Thread: Cermark Dishwasher Safe + Yeti Laser Settings

  1. #1

    Question Cermark Dishwasher Safe + Yeti Laser Settings

    I'm 99.9% sure Cermark is dishwasher safe correct? I have used Cermark on my license plate which I've had for 6+ years through NE winters so I'm pretty sure it won't wash off in a dishwasher.

    Also, does anyone have suggestions for Yeti powder coated Rambler Colster settings? I have a 35 watt Epilog & was thinking of using 100% power and 75% speed. Your thoughts??...

    100 power for sure but I would scale back the speed to 20 or 25. I run all of my Cermark at 600 dpi as well.

    When I use Cermark on the Yeti stainless steel tumblers I use 10% speed. Are you saying I should use 20% to 25% speed for the powder coated ones without the use of Cermark?

    Sorry, I mis-read your post. Yes, I use a higher speed on powder coat than on Cermark. Try 20%.

    As far as Cermark being Dishwasher safe, yes it is. However, correct me if I am wrong but I believe Yet's and other double-walled vacuum sealed drink coolers are to be hand washed and not put in a dishwasher. I supposed it has to do with possibly breaking the vacuum seal between the walls. If the vacuum seal is broken then the insulating properties (and thus performance) suffer greatly.
    Thanks,

    I had no idea how tough the powder coating is on the Yeti's. I have a 35 watt laser so that could be part of the problem. I'm engraving @ 600 dpi, 100 power & 8% speed (first pic). I tried 6% but oddly enough the engraving was even worse (see 2nd pic). All I can figure is that it may have been out of focus. I've auto focused one of the coozies and kept it at that setting. It's almost as if each one may need to be auto focused since the thickness of the coating may vary slightly?...?

    Are the JDS Polar Camel tumblers any different? Do they have a thinner coating to them?

    For me the Yeti black is the easiest of the powder coated finishes. I get a consistently good result with one pass at 100p, 27s, 500 dpi. My machine is 45 watts and is a fast machine in the raster mode. I use a cleaner and Magic Eraser after engraving.

    Wow, that's amazing! I'm totally bummed these didn't come out as good as yours. I autofocused each one after I did a few with not the greatest results. Still didn't matter. I used my rotary attachment and double checked that the mug was level which it was. Given your settings and machine I'm wondering if my laser tube is on it's way out as it's almost 13 years old.

    Do you think I used too slow of a speed (8%) which caused melting or bleeding? Is that even possible with a powder coating?

    Not likely with 35 watts

    Then perhaps my tube is on it's way out.

    I know there are laser meters but I believe there is also some test and math formula to find laser output. I thought I read something either in Engraver's Journal or A&E about this formula within the last few months. Does anyone know what I'm talking about or have a link to the article? I tried doing a search on both websites but didn't find anything.

    I wouldn't use/trust auto-focus, Just your your gauge for focusing. See if that makes a difference. I pulled my auto-focus plunger out of my Mini, years ago.

    I was afraid to engrave a 2nd pass on these since I was using the rotary attachment. I've tried re-engraving with the rotary attachment before but it didn't line up properly the 2nd time.

    I've called my customer & told him I wasn't as happy as I thought I would be with the end result so I'm not charging him as much as I had originally quoted.

    I guess I'll have to buy one & experiment.

    I have noticed that cutting through 1/8" thick plywood has been problematic and I am giving a little more power on cutting & engraving plastic as well so I'm wondering if it could be my laser tube.

    You may have a tube issue but there is definitely a big difference in powder coating, as everyone else has said. Even if your laser was putting out the full 35 watts you would still have trouble. I have an 80 watt machine and it takes multiple passes to get a clean mark on powdercoat. The alignment issue on your rotary is a separate problem - do you have the hot-dog roller type or cone type? If hot-dog then you'll never be able to do multiple passes, if cone then you should.
