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 / 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!

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.

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?

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

A3 Eleksmaker used to engrave leather goods.

The standard feet only raise the frame around an inch from my workbench. So if I want to engrave say a handbag, there is insufficient clearance to slide it beneath the frame. I'm using four soup tins to prop up the frame, but I would like a more stable solution, ideally a set of modified feet. Has anyone got any suggestions? Thanks very much. Mike.

T2 Engraving / resizing logo
« on: May 14, 2017, 02:06:30 AM »
Question from an absolute novice...
I'm trying to engrave a logo onto a piece of leather. It's a jpeg file, size in mm is about 120mm square. I want to enrgrave it at around 15mm square. So I open the file in T2Laser, and I use the 'Output size' option to reduce the size in mm, keeping the aspect lock on. Problem is, my logo then becomes totally smudged/blurred and unusable. If I use the 'auto trace' option on my logo, and then try to resize, the logo reverts back to being a solid image, rather than a traced outline.
Could someone give me some idiot-proof advice on how to do this properly please? Thanks very much!

T2 Engraving / T2Laser setup tutorial
« on: May 13, 2017, 03:29:53 AM »
Just assembled my Banggood A3 2500 laser engraver, but I'm having problems getting it to work properly. Tried Elekslaser software but it wouldn't install properly on my Win7 laptop. Then tried Benbox but couldn't get the laser head to move more than around a square cm.

Now trying T2Laser. The UI is great, easily superior to the other two. I've done the firmware, but now I'm stuck. The belts seem to be nice and tight, and when I move both axis slowly by hand, they are smooth. But when I use the directional arrows via T2Laser, the laser head moves in a very jerky way. Even if I just try to move the laser head axis on its own, the other axis moves slightly too, producing a small zig zag pattern. I can't see a 'start' or 'burn' etc button anywhere, and I seem to be a long way away from actually engraving images. 

Can anyone give me a point by point beginner's guide, or some tips on how to test that everything is working properly. I eventually want to be able to engrave text onto leather patches. Thanks very much.
