Cutting / Re: dotted/dashed lines

I've had some great success scoring paper by very carefully calibrating the power of the laser for the particular paper and card stock. See if this post helps: http://benboxlaser.us/index.php/topic,3144.0.html - There's a calibration G-code file attached in the thread that you can edit by hand to adjust the feed rate to suit your needs if you're familiar with a plain text editor.

T2 Engraving / Re: Multi Pass Engraving

I don't know if you would get perfect alignment with multiple images, backlash may not be constant so the result would be a "soft" or blurred image.

Zax, just FYI there have been a couple of posts on the Elekslaser Facebook group where someone's done a 2 pass engraving with the first pass on diagonal and the second pass on horizontal to get a deeper engraving using T2Laser. It looked pretty sharp from the photo.

Coincidentally a friend and I are  building a Lichtenberg wood burning rig with a microwave oven transformer in the next few weeks. Weíll just use the 2KV MOT out of that! (-;

The challenge that weíre mostly concerned with is finding adequately insulated wire rather than the actual wiring.

Iím looking forward to putting a solid ash lap steel Iím slowly building under the burner and seeing what happens.

@kibodwin Apparently the ď13min laserĒ comes with an annual maintenance visit from a technician to keep the machine in tip top shape as well. (-; I assume the annual visit is probably worth more than a K40...

John Trotto (forum member @jtice) shares his secret sauce for his painted laser engravings on YouTube here:

His tips and a jig that holds your coasters in place for accurate registration on separate engraving passes should be what you need.

Best,

Thanks @Zax for all your time and effort into making wacky Illustrator DXFs import into T2Laser properly. Now I can really go to town with vector designs. Iíve got in mind some experiments along the lines of Eric Standley (https://www.thisiscolossal.com/2014/08/eric-standley-laser-cut-paper-windows/) but donít know if I have the patience and time for it. Still got to finish that Illustrator to T2Laser tutorial first!

And thank you @ggallant571. It was a lot of fun to make.

Trouble Shooting / Re: X-Axis wobble
« on: July 29, 2018, 02:54:03 AM »
@KEtheredge87 - Are you running the two Y axis steppers using stealthChop or spreadCycle mode? I replaced my factory steppers with the Trinamic 2130s some months back and after fixing some thermal setup issues and jumpering them in standalone mode, I've been delighted with their performance. I run my X axis in stealthChop but my Y Axis using spreadCycle mode to give the steppers more torque. If I find some time this week, I'll measure the voltage settings on my 2130s and report back.

I'm running an older 2 year old Eleksmaker L7 board though instead of the Mana SE. I don't know if there's been any improvement in the stepper circuitry between the two versions. I use T2 Laser but there's are some custom calibration Gcode files I made to calibrate cutting through origami paper and card stock. Try that and see how you go with engraving/cutting squares if you have some non-white origami paper and card stock handy. The Gcode files use a constant feed rate, and step through power settings from 10 to 250 in increments of 10 and then a final square at 255. (It also puts a diagonal through the square because I use it to calibrate scoring paper for folding, without actual through-cuts.) I imagine Lightburn can load Gcode files directly to burn?

Download the set of calibration files from http://ianchia.com/images/laserart/Gcode-paper-and-cardstock-calibration-files.zip

Thank you @ThothLoki. (-: It was a thrill giving it to my friends and seeing their reactions as they read the words and realised the clock was made of up their lyrics.

Projects / Typographic designed LP Record Clock

That title's a bit of a mouthful.  ::)

My friends in the band Sumner released an EP earlier this year. I felt it important to celebrate their first EP release as a band so I made two of these clocks as a gift for them from the lyrics of their song ďLoverĒ on the EP (I find it fun to listen on listen on Spotify or Apple Music and read the lyrics on the LP at the same time). I designed it using Adobe Illustrator and prototyped it with cuts on cardstock using a A3 2W Eleksmaker. I went through a few iterations to find sections that didnít connect properly and sections that were weakly connected so I could add extra tabs that joined the letter forms.

The final design was cut from 3mm MDF with the local collegeís 60W Trotec Rayjet. Cutting through the 290x290mm cardstock took approximately 1h50mm with the 2W Eleksmaker. The 60W Trotec cut through the 3mm MDF design in 13 minutes! It was amazing watching the Trotec's laser head zipping around and cutting the MDF like a hot knife through butter. The final laser cuts were sprayed with a couple of gloss coats of black acrylic and a custom paper sticker label was designed by scanning an old Sly and the Family Stone album with some discreet Photoshopping to replace various elements.

(IMPORTANT NOTE: Do NOT cut or engrave vinyl records. It will create hydrochloric gas from the chlorine released which is highly hazardous to your lungs and also your laser.)

Zax has been helping me by dramatically improving the import of Illustrator generated DXFs into T2 Laser (currently in heavy beta-testing) and Iím slowly writing up a tutorial on how to create a design like this in Illustrator to import into T2L. Iíd like to note that Iím an extremely happy customer of T2 Laser based on Zaxís *excellent* customer support.

Big thanks also to Dougie Smith on a Laser Engraving Facebook group who shared a record design he made, which was the original inspiration.

That swanky thing is a prototype I just finished building to support pilot training. It's a Garmin G1000 training software control panel...

Very impressive Ralph. Thank you for sharing.

The forum is growing because of the number of posts being made each day and the number of uploads is taking up a lot of disk space. I have to keep upgrading to the next hosting package size (more $$$). If anyone cares to donate a one time donation it would be appreciated -- or -- make a recurring $1.00 donation each month would help as well.

Thank you...

Just paypal-ed you my contribution for the year. Thank you for your support and maintenance of these forums.

Best,

Thanks for arranging to get the attachments issue fixed Ralph. And what is that swanky image of? Something you made?

I'm still having problems with normal attachments on old posts.

This one for example: http://benboxlaser.us/index.php/topic,3280.0.html

I added img tags to point to my server just now so the post showed images but the attachments for various posts are still 404, for the images, the pdf and cdr files I posted.

Thanks for looking into it Ralph.

All the best,

- Ian

Hi Ralph,

On a desktop browser on the left of the post, all our avatars are still 404. Here's a link to your avatar for example: http://benboxlaser.us/index.php?action=dlattach;attach=7886;type=avatar

You're not doing anything wrong. The server's having some software issues that I hope Ralph the admin will attend to in due course.

(And thank you Ralph for hosting this box and all the maintenance that comes with it.)
