Trouble Shooting / Burn issue
« on: January 13, 2021, 12:52:07 PM »
I'm using an eleksmaker A3. It has been everything and more than I could have hoped for when I bought. I'm also using T2laser to drive it. T2 has also been a joy to use. Suddenly I'm getting a tail, a shadow, or an overburn on my designs. I've cleaned and tightened the belts but I'm still getting it. Open to suggestions as to what may be causing it. Could it be as simple as reducing power?
thanks for any thoughts

T2 Engraving / Suddenly T2 won't load
« on: January 06, 2021, 09:16:43 AM »
I've been T2 for a few years with no issues. Today when I tried to load it I got an error message

If I tell it to load I get the home screen but whenever I try to do anything I get this error message.

I think it may be related to a driver I just installed but not sure. A CH340 driver. I tried disabling the driver but still get the same errors. I have not tried uninstalling the driver. Appreciate any help or suggestions.


Assembly Help / How hot do stepper motors get?
« on: March 25, 2018, 08:11:22 AM »
On my rotary machine I have two motors on the y axis, the axis I use to rotate the work piece. The x axis, which drives the ball screw to move the laser back and forth has one motor. The two rotational motors get warm but the x axis motor gets too hot to touch. Is this normal and/or acceptable? If not, I think I have two options, get a beefier stepper motor or invest in a 3 axis mana se and put two motors on the ball screw as well. I want to keep two motors for the rotation because eventually I'll be turning some larger work. Any thoughts or suggestions or do I just not need to be concerned?


T2 Engraving / Create a dxf to equal one rotation on a rotary axis?
« on: March 18, 2018, 05:29:36 AM »
Is it possible or would it be possible to create a dxf in Inkscape that would equal one rotation on the rotary axis? I remember from using the eggbot extension in Inkscape that's what I did.


Projects / 2nd cryptex
« on: March 17, 2018, 10:14:35 AM »
Here is the second cryptex I've made with the rotary engraver. This one has a five ring code and I changed the pattern for border rings. I like the look of this one much better.  FWIW, each border ring was burned twice to get the pattern dark enough and to take out some light spots. It's simply amazing to me how repeatable these little stepper motors really are. The rings are maple and the end caps are walnut.

Projects / My first project from a rotary machine.
« on: March 10, 2018, 01:38:16 AM »
I'm a wood turner first and am excited about what a rotary axis can do for me. This is my first project and one that's been in my mind for a long time. This is a cryptex from the movie, "The Davinci Code" It's the prototype and I'll work on fit and finish before making one for each of the grand kids for Christmas.


General Discussion / Inkscape question
« on: March 08, 2018, 10:34:45 AM »
I use inkscape to write pretty much everything I burn. After creating a document I often outline the document with a square, no fill, and yellow line color. That allows me to control how the dxf imports into T2 and I know exactly what the burn area will be. Been using this method for several months with no issues. Suddenly when I now do that, one, a few, or all of the elements in my drawing also turn yellow when I save as a .dxf  When I click on the elements before saving the lines are listed as black but  still save as yellow. I don't know if this is a bug or something I've done to cause this.


T2 Engraving / Rotary axis question
« on: March 05, 2018, 12:35:49 PM »
I'm still learning the nuances of using a rotary axis and I have a question. My patterns haven't been coming out exactly right, it seems they are either just too long or just too short.
I wanted to do a test line around the circumference of a cylinder. I had a piece in my machine 62.12mm in diameter. Pi*diameter tells me the circumference is 195.0568mm
I then opened sketch and created a document x-axis=30mm as that is my laser axis but doesn't really matter for this. y-axis=195.0568mm which rounded to 195, not a big deal I think.
On the laser control screen under rotary axis, I entered 62.12 for the diameter but it tells me the circumference is 195.156mm.
What am I missing?


Assembly Help / Adding a pull down resistor to a ttl laser board
« on: February 27, 2018, 03:22:48 AM »
I posted this in a new thread because I thought it might make it easier to find in a search. I want to be perfectly clear I understand exactly what to do. So I want to solder a resistor across the two pins I have circled on the TTL board? To my non electrical mind that seems it would cause a short. 


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.



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


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

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 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.
