Laser Pointer Ripped off

Community Laser Talk
1

Got my new rotary attachment in today. In the process the laser head was returning to home position and I had to quickly remove a tumbler. It ripped off at the connection points on the laser pointer circuit board.

I taped up the two bare wires and made sure they weren’t near each other. When I went to fire the laser for a test, the red/black got hot and started to melt further up inside the heat shrink…

Do you HAVE TO HAVE a red dot laser for these to work? Not sure why those to wires got hot to be honest…

You don’t need it to operate the laser unless the wires are now shorted.
If you follow the wires back to the electronics area, you will probably find they go to a small box with a lot of holes in it. That would be the low [5v and 24v] power supply. WITH THE POWER OFF and unplugged. Disconnect the wires, and tighten back the screws for those wires.

Thanks for the info. I’m trying to find a replacement. I know how to solder, but this is really, really small wires that connect to the laser circuit board.

Appreciate the feed back.

Small wires, yes! I also learned that the wires, from China, are frequently aluminum with a copper coating for soldering. So if you scratch the wires during the stripping of the insulation, there is very little copper left for the solder to stick to.

There is some flaw in how you have this setup. There should never be this kind of issue… The Y axes shouldn’t be moving… are they?

You’re taping them back together resulted in a short between the supply and ground… The short caused excessive current to flow and the wires just couldn’t handle it.

If you know how to solder you should have soldered them and you would’ve probably seen there was a short… :face_with_spiral_eyes:

I haven’t had a laser red dot pointer since about a month after getting the machine… I took mine off, guess I’ve never missed it on the CO2. Would be lost without it on the fiber :crazy_face:

When I first read this, I thought someone had stolen it… Ripped off is a slang term for it being stolen from you or by you…

Good luck

Well, hello there Mr.Jack. Hope all is well. Na, I just put tape over the 2 ends. I didn’t tape them together…I’m not that brave… :wink:

Anyhooooooo, I just did another test, and it ran fine as is. Still looking for a replacement though.

On the CO2, I found the led to be more of a headache than it was worth…

Any lens positional change or length of lens, you have to re-adjust it…

Didn’t work out well for you either :crazy_face:

I’d like to throw this in the mix. Setting up my steps per rotation on my new rotary. Got it. Created a 20mm x 20mm box, and it’s on the money. Lovely

However; for what ever reason, I cant get engraving to look good either fill or line. The font is Arial. The word is “You”.

I have my layer set to 00. Power 40, speed 30 just to test. Where should I look to fix this?

When I do a fill, it truncates part of the last letter as well.

The pictures appear as if the mug is slipping on the rotary. Do you have a chuck or wheeled rotary?

Are your speeds in mm/s?

I don’t know of any reason that fill wont’ work… The controller doesn’t really seem to know if you’re using a rotary or not.

Do you get any warnings from Lightburn about anything related to closed objects?

Hello there Mista C

Come to find out it was my job orientation that was the villian. Jason from mansfieldcustoms helped me with it. I also had to change my steps per rotation from 4100 to 2000. It was only then that I could draw a 20x20mm square and it measured out correctly.

And on the line engraving, he thinks it nothing more than a speed issue. He thinks if I slow it down, that should work out as well. I have to tweak the Line Interval some more though.

But I think I might be there.
