EleksDraw / Mana se drivers
« on: February 04, 2018, 05:41:37 AM »
I have an eleksmaker A3 with the nano controller. I'm trying to build a new machine and the controller I have for that is a mana se. Do I need to install different drivers for that controller?

Custom Size Frames / Building an eggbot type laser
« on: January 15, 2018, 08:08:05 AM »
I'm a wood turner and I want to build a machine loosely based on the eggbot chassis, the fabrication on a prototype is nearly done. I can handle that part of it just fine. The electronics is way out of my comfort zone however. I have ordered this laser

I have also ordered these stepper motors which I believe will be sufficient for what I want to do with this machine.

A while back I ordered what I thought was the same controller that's on my A3 machine but after a little more research I'm not sure if it will work for me. It's this one.

I'm not sure if this is exactly what I want, if it's not, can someone tell me what controller I'd want to order? A link would be greatly appreciated.

Thanks

Is there a tutorial on adding home position switches to an eleksmaker A3 machine. Seems as though I've seen discussions but didn't find anything

Thanks

T2 Engraving / Something I'm doing wrong.
« on: December 02, 2017, 03:54:28 AM »
I've gotten pretty comfortable creating dxf files with inkscape and importing them into T2 laser but suddenly I must be doing something wrong. I found a website that will create mandalas and let a person save them as an svg file. I thought this was great because I use that format all the time. So, I created a simple mandala, opened in Inkscape, manipulated to suit me and saved it as a dxf. Opened t2 laser but it doesn't see the file. My computer sees it as a dxf, delta cad sees it as a dxf. T2 laser doesn't see it at all. I thought ok, copy and paste it into a new file, save it and try that, nope, T2 laser doesn't see it. Even if choose *.* it still doesn't see it. I've tried opening it in deltacad and saving it, nothing seems to work. Appreciate any help or suggestions.

The website to create the mandalas is  http://mandalacreator.com/

Here is the file,

Laser Modules / A side by side comparision
« on: April 16, 2017, 05:42:29 AM »
 I'm still contemplating upgrading to a TTL unit for my A3 machine. It's my nature to pretty much wear something out before I make a purchase as I like to be as informed as possible when I decide to buy. I'm still not entirely clear on just what advantages upgrading will give me. Has anyone done a picture or graphic using a "regular" laser and then the same picture using a TTL unit?.

Laser Modules / Upgrading to 2.3watt TTL
« on: April 08, 2017, 05:52:09 AM »
I have the A3 2.5W and have been reading that a TTL unit would be a better option. Banggood has http://www.banggood.com/445nm-2_3W-2300mW-Blue-Laser-Module-With-Heatsink-For-DIY-Laser-Cutter-Engraver-p-1105563.html?currency=USD&utm_source=criteo&utm_medium=cpc&utm_content=all&utm_campaign=electronics-US this one. Is it a good option? How difficult is it to incorporate into my machine? I DO NOT understand all I know about what I want to do. Any thoughts or advice welcome.

T2 Engraving / How critical is distance?
« on: March 11, 2017, 06:25:37 AM »
 I'm sure this must've been discussed before but a quick search didn't find it. Very little of what I do is perfectly flat, most times there is a gentle curve and I've not had a problem. I have plans to to etch patterns on items with more exaggerated curves though, think bowl or wooden vase. I can see my focal point moving as much as two inches or so. How much can the distance change before the burn deteriorates significantly?

T2 Engraving / Seeing the starting point with the "veiw" option.
« on: February 11, 2017, 05:48:03 AM »
I have been happy with the version of t2 I originally purchased so I never upgraded. I was reading the thread about rotating a dxf and decided I would go ahead and install "wales." It was a nice surprise to see the red dot in the middle of the view screen. For someone like me nearly always engraves something round and uses center start it's a big plus. It lets me see how much clearance I have around the center. Important because I usually have a knob or something placed there. Thanks!

T2 Engraving / Inkscape question
« on: January 29, 2017, 11:46:14 AM »
I am burning simple graphics, think line drawings, with some text added. The text is from an extension called Hershey text. I'm burning on maple, cherry, and/or walnut. My settings are for fine resolution and the size is approx 66mm X 66mm. If I burn once the text looks good but the graphics are a little light. If I reburn, the graphics look good but the text is not as crisp as with just one burn.

Using layers in Inkscape hasn't really worked for me or that would be the obvious solution I think. I had the thought to create the file, delete the text,  and save it to a dxf and call that file_a . Then to do the same thing but delete the graphics instead, save it to a dxf and call that file_b.  It seemed to me that everything should/would stay in place and I could burn either file to suit me. It doesn't work, both the graphic and the text shift position some and the burn doesn't look the same. I typically use "center start" and when that didn't work I tried "center start>absolute. Neither one worked for me. Any suggestions?
Thanks

Spare Parts Sources / 2 axis stepper motor controller
« on: December 09, 2016, 03:19:18 AM »
Is this the controller that comes with the 30X40cm and other laser engraver kits? If a person were to build a machine from scratch is it a good place to start? Would it handle a nema 23 motor?

Other Software / Something I don't understand
« on: November 30, 2016, 04:40:46 AM »
Most of what I've been engraving is basically a wooden disk about 3" in diameter. With that in mind, when I'm creating a graphic and/or text in Inkscape I set my document properties to 66X66mm or just over 2.5". That way I know anything within the border will be engraved. After editing, I save the file, first as an svg and then save it again as a dxf.  However, when I import the dxf into T2laser the size  always comes up as something over 160mm. Not a big deal at all as it's easy to resize for engraving. Just curious though as to why the size changes like that.

Other Software / This is an inkscape question
« on: November 20, 2016, 10:21:34 AM »
I've been drawing something I want to engrave with inkscape and part of it is text that follows a path. I can do all of that ok but when I export to a dxf the text changes from solid to outline. As yet, I haven't figured out how to keep it solid, anyone know how to do that? I do have black selected as the fill in the fill and stroke dialog box.
Thanks

T2 Engraving / Question about text overlay
« on: November 08, 2016, 06:55:33 AM »
I have a png I've been burning on my mason jar lids. I've been trying to add some text with sketch plus and it's arc text. I would like to wrap the text around the bottom of the image and that's how it looks when I send it to the laser. When it burns however, the text is in the middle of the image. I am using center point start for the image. Haven't figured out how to change that yet.

T2 Engraving / Engraving a bee hive pattern

Is is possible to do an image like this?



I have been desaturating it in gimp and then choosing grey scale to burn. Not getting results I'd hoped.

T2 Engraving / Don't know if this qualifies as a bug.
« on: November 02, 2016, 04:19:00 PM »
I think not but it's something to be aware of I think. I was playing at burning some more lids today. I am using an old laptop to run the machine and had it set to sleep after an hour. Wasn't paying attention, the computer went to sleep and the program stopped executing, except the laser stayed at full power. When I noticed, it had burned a hole through about 3/8" of material. I don't know what the implications are but is that possibly a dangerous scenario?
