T2 Engraving / Multipass on DXF file?
« on: August 31, 2019, 10:08:48 AM »
Hello all,

I am trying to make some small tags for my mom, and it is essentially some clipart and text on a piece of leather.

I would like the image and text to just get 1 or 2 passes, or a slower pass, for example,

Then the edges and some circle (holes for thread) to get multipasses and be cut free. 

Essentially the sketch Plus (Overlay) function,  but it doesn't seem to work on a DXF import.

I hit AutoTrace, and click outside the art, but nothing turns red. 

I would also like to set up the colors = cutting speed fuctionality, but I have no idea how to adjust those settings and assign a color.

Thanks all. 

I'll attach images once I get to work and can dig them out of gmail.

T2 Engraving / Laser runs off the side
« on: August 23, 2019, 04:10:09 PM »
Hello again all. 


I've had t2 laser for a few years now but I'm still a newish engraver.


The biggest issue that has kept us from really engraving is the laser running off the engraving area, and the motors grind against the strap, trying to keep going.

I have the eleksmaker a3, which t2 identifies as a 300x 400 work area.


However something else must be wrong because the laser still tries.

I would like to set the laser at the lower left of the art work, not the canvas, so I can start the project where the work is going to be.


I have set the origin 0,0 where the laser is at, set the lower left as the origin in settings, hit start for the small test square, and zoom it goes off the grid.    I hit the emergency stop before it can damage my motors.



Any help finally solving this would be greatly appreciated.   I will measure the actual workspace and go through the adjustments tab and check on the 80 steps per mm default once I'm off work.


Texting from a cellphone, please forgive the brevity.

T2 Engraving / Staining wood
« on: December 22, 2017, 01:15:08 PM »
Hello all. 

I've been pumping out Christmas gifts with my laser and I really owe it to the help I've received from everyone here.  Thanks for that!

I was wondering if we could finish off the wood with stain before the engraving in order to get more contrast, and also how to seal off the wood post engraving? 

I am thinking probably clear polycoat?

So far everything I've done has been left raw.   

I just did some leather cutting, and then sealed it with Leather Waterproofing spray (for tennis shoes).   Made me curious.

T2 Engraving / Timed Pause command
« on: December 17, 2017, 02:13:17 PM »
Hello all.   I've done a few test jobs on plywood, and with Christmas around the corner, we are thinking about trying some initials and logos and such on some handmade gifts. 

I have noticed that some image engraving and such have job times over an hour, and I've read somewhere that these diode lasers need to rest for 10 minutes every 10-15 minutes. 

So I have 2 questions really....

A)  Is that true?  For a passive cooled A3 setup (No upgrades, no forced air cooling or anything not included.)

B)  Is there a way to pause T2 every 10 minutes for 10 minutes, and then have it auto-resume?   So far I've been using the egg timer and the "I'll go pause it if you get up and resume it" negotiations with the spouse.

C)  ... bonus question, I've been searching these forums for information on leather engraving, and all I've found are the 3D printed feet to fit a purse under the laser.   I was wondering if anyone had suggested settings for engraving logos into leather, and any pictures of results?

Thanks in advance for all the help!

Trouble Shooting / Stepper motor not catching the rubber tread
« on: July 07, 2017, 05:09:07 PM »
Hello all,

First post but I have been trying to absorb all the information here over the last few weeks. 

Finally my Elekmaker A3 arrived from Banggood.com, and it's been assembled.   Currently running the trial version of T2.

The upper motor spins, but the rubber tread just rests on top.   

In order to get a demo to cut, my wife pressed down on the tread before and after the motor, to provide proper tension, and everything worked fine. 

We slowed down the speed to 250 from 1000, to give the treads more time to catch.

We have tightened the tread anchors at least 10 times, and they do not visibly slip when the motor starts to skip, but the slack in the tread is obvious.   

I am afraid to tighten the anchors more than we have already, but the tread seems to just stretch out more and more rather than properly engage.

Thanks in advance for any help.
