Need a bit of guidance

on this one.

I’ve been using my 110 lens on my 50w JPT fiber. Really like it. Was struggling with removing the powder coat on this particular blue, so I figure, heck let’s throw my 200 on it.

Steps per rotation is 12800 on this rotary. I tried to create a 10mm x 10mm square, and I get this crap. Those 2 silver blocks is what it did. The circumference is 85.3mm on this tumbler. It’s the only tumblers I use.

Did I change a tick mark somewhere and didn’t know it. It’s engraving using the Y axis like like the 110 was doing…

I’m lost at the moment… All I’ve done is change the lens to one with a wider field and deeper focal point.

Did you get the right lens correction loaded?

:smile_cat:

Lens Correction? Loaded? I knew there was something like that, when you don’t use a rotary, but not with a rotary.

All I did was go from 110 to 200 lenses.

I don’t remember even seeing that with my 110mm on.

I do remember seeing a video on that subject when your just laying a tumbler down on a jig, and not using a rotary.

I did find this.

I’ll watch it.

If you got these with your machine, hopefully they did a calibration for you… You should have some kind of file for that lens…

If you can’t find it, you should drop a note to your vendor…


I hope you loaded the configuration file from EZCad when you created the device…

:smile_cat:

Yeah, I loaded EZcad and copied the file for each lens over when I created the appropriate laser with it’s lens, and have them identified in the name. The thumbdrive came with 2 folders on it, representing the lens size. What has me scratching my head is I didn’t do any configuration for the 110. I slapped it on, selected the appropriate laser name based on the size lens I have on it, found the sweet spot using a aluminum biz card, documented the height for the lens, and done.

I throw on the 200 and I get this stuff.

Does it work OK without the rotary?

:smile_cat:

I tried the lens once on a coke can cradled similar to a vid I saw, and used LB cylinder correction. That was one time. Yesterday, was the 2nd time I tried this lens out, except it was on the rotary.

Use it on something flat to see if it’s doing what it’s supposed to be doing…

:smile_cat:

Will do. I did use a biz card on it, to find the proper height to use it. I can do that again, and see if I get a 10mm x 10mm sq.

I have an update on this.

My diameter of the tumbler changed within LB, and I didn’t notice it.
I ran it with the 300 lens on it yesterday evening an it was marking 10x10mm squares and letters with no problem.

Lesson Learned.

I think that’s part of where live and learn comes from…

At least you have it solved…
