General Discussion / Cleaning and maintaining laser engraver
« on: December 12, 2020, 02:24:56 AM »
I've been using my Banggood A3 engraver for over four years to personalise leather goods. Usually everything just works, but this year the controller on/off button has started to fail, and sometimes I have to fiddle with it for a good few minutes before I can get it to switch on. I've started using the wall socket switch to power up/down instead of the controller button. Also the X axis makes an unpleasant grinding noise, and I occasionally get bits of dried carbon dropping down from the X axis and onto my work. The 2500 laser head seems fine, but two of the top screws have corroded (my workshop gets pretty damp this time of year). I've bought a new controller and once work gets quieter I'm going to fit this and give everything a good clean. Has anyone got any recommendations about how to clean and lubricate these machines? WD40? Light oil? Any bits I should replace when I take it all apart? Thanks!

T2 Engraving / Re: Loss of resolution
« on: September 12, 2020, 11:05:51 AM »
I think Iíve solved this now.

I went back through my workflow, and I found that if when I typed in the text of my engraving on my word processor, I shrank the page magnification slightly, then followed all my usual steps as stated above, the engraving came out just slightly bolder / blacker.

So at least I know my laser isnít failing. I cleaned the laser with a bit of white spirit too. No muck came off, and the glass seemed to be spotless.

I think my laptop and word processor both updated recently, and thatís what caused this problem. But itís sorted now. Thanks for your help gents. Zax Iíll definitely have a think about the steps youíve recommended, but as I said, if it does what I need it to do then Iím happy to just leave things alone.

Yes there is an oily smoke, and no I have never cleaned the laser - but I will do that today! Thanks.
I know this is a daft question, but what should I use to clean it?

Hi Zax. Honestly, after lots of trial and error with your software a few years ago, I know how to do what I need to do - engrave my customers names on leather - but otherwise I haven't got a clue. I don't know what raster engraving or vector feed rate means. I type the words into a word processor - I use the snipping tool to cut a rectangle shape round the words - and then I open the image file in T2. I definitely haven't changed any of my settings.

Are you seeing anything in the photo of the lighter engraving that would make you think my laser is failing? Do they fail gradually, or suddenly? It looks to be functioning exactly as normal.

If the laser isn't failing I think the answer is probably going to be the quality of the leather. I use oiled leather, similar to old style biker jackets, so it could just be that I've bought a batch thats been over-oiled, or perhaps the manufacturers have used a new type of vegetable oil.

Thanks again for your help.
Mike.

T2 Engraving / Loss of resolution
« on: September 11, 2020, 03:33:01 AM »
I haven't made any changes to my regular settings, but my engravings appear to have become faded, and they lack resolution.

I engrave onto leather. My lettering is usually about 18mm high, and my laser is set at 3000 / 0.05 / horizontal.

You can see the difference in the two images attached. One engraving from a few months ago is much blacker than the other from a few days ago. This faded appearance has happened on my last five or six jobs. It possibly coincides with a Windows update. It might also possibly be to do with the quality of my latest batch of leather, but I'm just not sure.

Is my laser failing maybe? Or can anyone recommend adjusting a setting that would give me better resolution?

Thanks!

Don't worry Zax, I've got it, I was looking in the laser controller menus rather than the image menus.

I'm all working properly now, thanks as always for your quick reply and help

Hi Zax. Just remind me, how do I select Centre (Start Point) ?

T2 Engraving / Home button glitch
« on: May 28, 2018, 10:06:57 AM »
I just changed my computer, and I'm running into some very small problems, most of which I have been able to fix.

One problem which is really bugging me, and I know there is a simple solution, is that my laser doesn't home properly. I skips up to the right, and lasers away from where I want it to.

Ive manually centred my laser, then right clicked the home button, but it just keeps skipping to the wrong place on my bench.

Could someone tell me, in laymans terms please, how to fix this?

Thanks so much. Mike.

Yes, I'm using your Grbl 1.1e.
I'll enable the dynamic laser power option and report back.
Thanks for the replies!

T2 Engraving / Linear edge fringe burn
« on: March 26, 2018, 02:34:29 AM »
Hi all. I use by Eleksmaker A3 to engrave leather goods.

I use linear mode, which seems to cause a slight burn at the extreme ends of each engraving. You can see in my photos, the left side of the letter M, and the right side of the letter i are both darker than the rest of the engraving.

I can eliminate this by using diagonal mode, but that causes my machine to vibrate and as such I lose definition.

Can anyone suggest how I can eliminate this fringe burning but keep linear mode?

I'm using an ancient battered old laptop, so presumably that's the problem, although before today's update it did the job fine.

YES! That fixed the problem, thanks very much Zax I really appreciate your service.

I'm hopefully about to get very busy with my engravings, right through to February. I need to have my setup ready for work without hiccups, so do you think you could revert to optional updates, at least during this busy period?

Thanks again man. Mike.

Hi Zax.

I've never set up a profile, just done lots of test runs and small adjustments till I got everything set up perfect. I definitely haven't changed any settings myself today, the speed and res are both exactly as they were.

I guess I'll just have to start testing / adjusting again, but it is strange that the job time estimate indicator is now so inaccurate..

T2 Engraving / Latest update causing problems
« on: October 26, 2017, 05:33:16 AM »
I just had my T2Laser update install itself automatically. It didn't give me the option to accept or decline.

Now my laser is operating very slowly, so much that it's burning through my leather products. I was literally in the middle of a job, so the first engraving was fine, the second engraving, done after the auto update, and with no alteration in settings, took forever and burnt my product (a now ruined hand made wallet). I've repeated the first engraving, again with all settings identical, and it too has burnt through. A 1m.30s job took around 8-10 minutes.

I've turned everything off and on again.

How do I reverse this latest update please?

I'm on V1.5c, Win7, and my laser setup is mechanically sound
