Taper Warp. Tumblers and Round Logos? One Size Does Not Fit All. Thunder Laser BOLT. 026 4K

I have come to the conclusion that you Gord are a Rennaisance Man. You're into so many different things with different teachings or methods. Very enjoyable to watch. Take care young man. God Bless.

[@LaserNUG]

Cheers Jerome! and thanks very kindly. :)

Good morning early Gord. Great video and interesting too. You're doing a great job getting all that figured out. Whose the boss? I'll write you. Stay safe and keep up the good work. Fred.

[@LaserNUG]

LOL! Morning Fred. Carol has to give it a thumbs up for sure. :)) Thanks - look forward to it. Have a great day!

[@RossOnTheLand]

So helpful! Excellent experiments,

[@LaserNUG]

Morning Ross!

[@nancyr8377]

I love your videos. It's like I am talking/thinking to myself! Always helpful.

[@LaserNUG]

LOL! Morning Nancy! Thanks - Have a great day!

[@nancyr8377]

on a 3.125" skinny, 5% on a 2.5" logo worked perfectly!

[@LaserNUG]

Thanks for sharing it Nancy! It is helpful for me and will be for others too. :))

Gord, all you're asking for mathematically is to convert chord length to arc length. Use this online calculator to account for the horizontal stretch of the logo. Whether or not you see it as skewed is completely dependent upon the ratio of the mug diameter to the logo width. You only need to enter 2 values into the calculator. Enter the diameter of your mug for "Diameter" & enter your original, unskewed logo width for "Chord Length." It will automatically calculate everything else. The "Arc Length" value is your new, stretched logo width.

Good morning and thanks very much for the idea. I will take a look at this today for sure. Cheers!

[@timwarren5021]

Thanks very interesting how the different settings (measurements) make the Logo look difference never would have thought about it.

[@wtfbuddy1]

Nice video Gord - you have it down pat, my eyes aren't the best to notice the aspect stretch of 2% to 5%, good to have the Boss to check the work lol. I think I'm ready to send you a email. Cheers and have a great week. Pete

[@LaserNUG]

Morning Pete! That would be great - thanks!

[@thesplinteredfinger]

Gord, thanks for all your research! Just subscribed to your channel. I like the way you explain things. Question for you, are you using the 30 watt Bolt and a 2 or 2.5” lens? I have a 80 watt Boss. I’m surprised at your settings 600/70. Everything I’ve read uses 400/40. Have you tried running slower? Thanks!

[@LaserNUG]

Good day and welcome - thanks for subscribing. I am using the 1.5" - yes , I saw that others offered that and started at 400mm as well a couple months ago, but over time testing different settings, I went from 400 mm to 600 mm now with excellent results (as shown). I still notice that similar to 400mm setting, some colours need either more or less power (sometimes I use 80% power) or a little extra cleaning - but 600mm settings are coming out great. Yes it is a 30W Bolt. Let me know how it works out for you. Thanks again and good luck!

[@mikekowal4944]

Professor!!! Great teaching skills😊 thanks!.. Is little Gord working with you ?

[@LaserNUG]

Good morning Mike! Hey, can you email me at gordpotter55 at gmail dot com. Thanks!

[@frankfarklesberry]

Interesting problem that I wouldn't have even anticipated. I'm impressed by the software's capability to deal with it, although I assume this challenge came up early in the development. Hey, looks like you have more tumblers now than we do. My wife the marketing communications expert gets free tchotchkes like this sent to her every month. No more cabinet space for them. LOL

[@LaserNUG]

LOL! Cheers Stan!

[@RonaldDean-eq2cb]

Hi G.P. Just a suggestion have you thought of maybe measuring where you are going to engrave and say it’s 2.5 inches make it 2.5%? I know nothing about it but I thought about it while you were speaking

[@LaserNUG]

Morning Ronald. That is interesting. I was thinking about seeing if that math works out. But have not put pen to paper. It might work. I know a couple of folks move the decimal over from the diameter ( ie 3.2" diameter, they use 0.32 and add it) but their results still look like the top and bottom of the circle looks flattened to me. Thanks Ron!

[@Oldmonstrosityshop]

So it looks like there is a formula between the diameter of the round logo and the diameter of the cylinder being engraved. 7% for big logos (closer to the diameter of the tumbler) looks good. The smaller the logo the smaller the stretch required if at all. Thanks for this 🙌 just a quick question - on a taper, is your focal height in the middle of the logo or at the biggest diameter of the object you’re engraving?

[@LaserNUG]

Good morning - that's a good question - I focus around the middle of the design area ( not necessarily the biggest part of the design) but more to the middle of the height of where it will sit

[@kerrieglasgow4076]

Thank you so much for this video! I have my library downloaded in LB for the Bolt....but all I have is "tumbler engrave". Did you have to input Powder Coat on your own? Thank you!!

[@LaserNUG]

Hi Kerrie. You bet! I did add it. And as I continue finding new materials settings, I have been adding them to it as well. That way I don't have to search back through my notebook. LOL. I have not added an Art library yet but will be adding it soon. Have a great weekend!

[@wojo6567]

They need to word it as measurements of the design area, not the length of the tumbler or item being engraved.

[@StevenTindell]

It looks like you have added 10% to the width, then the taper warp is adding a bit more. Why did you add 10% first?

[@LaserNUG]

Morning Stephen. Great question. I tested the circular logo several times with and without taper Warp. If i don't add the width increase, even with the Taper Warp, the circle still would not look like a circle so I still have to add a % to the width. Test it out (Taper warp with and without the added width adjustment) and let me know how it turned out for you. Have a great weekend!

[@StevenTindell]

I added 5% with warp, 6% with warp and 0% with warp and we came to the same conclusion. The Boss and I both liked the 5% but 6% was close.

[@LaserNUG]

@@StevenTindell Good stuff Steven!
