T2 Engraving / Re: Feed rate - units question.
« on: June 28, 2020, 12:30:28 PM »
I have (i think it is 2.5mw) blue diode laser and wanna cut cardboard stencils. From my experience, best paper for cutting stencils with blue diode laser is a red paper. red as a color. it cuts very easily and no burn marks. when i played with the settings, for that specific laser i had to stay with 300 feed rate (which is quite slow) and 255 power. but it works. I just needed to know what units T2 uses.
Thank you!

T2 Engraving / Feed rate - units question.
« on: June 28, 2020, 01:32:03 AM »
I have tried to find in what units is the feed rate, but wasn't very successful. Is it mm/min, or mm/meter? or in inches?

And what would be good max speed and max acceleration for a3 eleksmaker diode laser please?
Thank you in advance!

Got those files Ian and will run some tests soon!
Thank you very much.

P.s. That art you have created is VERY inspiring!

Pity I cant see your photos Ian :-/ Any other website where are they available?

Btw I have tried more white papers. Matt photo paper, artistic white success. I can live with that because I want that laser for stencils. Colored paper works for me.

So. I have mentioned before that I got some colored cardstock. Now I know what was causing those unfinished cuts...White paper. Damn you white paper!
Yeah. No idea why this laser has a problem with even matt white paper.

Best results : 300 speed, 150 power, vectors

1 red cardstock
2 navy blue cardstock
3 black
4 green
5 cyan

White, gray and all the very bright colors were useless.


Maker space? Hmm..dont know. have to do some research. I just bought my very first soldering kit and I am SLOOOOOWLY learning things about electronics :-)
Anyway. I got 165g cardstock in different colors and 195g synthetic translucent Yupo paper. It feels like very thin Mylar. Not saying that it can withstand solvents, but looks like great material for stencils. Gonna give it a try and I will post results. Crossing fingers.
Have a nice weekend guys!

p.s Was anyone able to download Ianchia's test files? Still getting error 404.

I Thought that there is already some small plug and play laser controller board or just a bunch of cables you just connect together...apparently this is not the case.
I need to have the skills you guys have but unfortunately I dont have them.

Thanks for all the help. I appreciate it!

How many wires between the controller and the laser module. I have 2, 3, and 4 wire fixtures.
Ggallant can you please take a detailed picture(s) and post it? I would really appreciate that.
Thanks a lot!

The laser driver is the constant current source for the laser diode, it's internal to the laser module.
I see. Hardware thing. Nothing I can do anything about.
Wondering what way can I connect the laser unit to its own power source and to the controller board at the same time? Do I need some very specific cable(s)?

@Zax that laser driver - are we talking about software which can be reinstalled? If yes I will do that. And the dynamic power mode was off.

@Ianchia no worries we all are busy :-) thanks a lot for response. Can you post a pic of how you connected your laser to that pc power supply? Would love to see that. I have one spare atx supply at home so I would try that. And I will definitely try your calibration files!

Ok. I got brand new power source 12V, 5A and I have done 3 tests. 2x engraving of the 2 pictures and 1x vector cutting. As you can see on the pictures, engraving went well. Haven't noticed any skipped lines or unfinished engraving. But when it comes to vectors, laser just keeps doing that unfinished stuff. Gonna get multi meter tomorrow so I can adjust all the currents. I would appreciate if you guys can give me some photo which would show how to measure current on this particular controller board and what should i actually turn / move.
Thank you so much for all the help and patience!

p.s. Regarding those vectors - circles in the left bottom corner have been made in T2 laser as a sketch. and the mask is the same file I have used for the very first test.

I have created the same thread on two diffrent forums. I saw that Zax (and many of other people) are active on both. I hope you dont mind that folks. Thank you very very much guys for all the help!

Cutting / Re: My "pin table" for eleksmaker
« on: July 16, 2018, 02:42:38 AM »
Hey Ian!
Yeah I love that pin table! absolutely no burned marks on opposite side of the paper. But I have to increase amount of push pins for more detailed jobs.
Btw do you have any idea what could be the problem with my laser as I have described it in this thread please?,3308.0.html

The numbers are from T2 laser under "help" menu under "samples" - feed rate test, power test etc.
the mask file is attached

Cutting / My "pin table" for eleksmaker
« on: July 15, 2018, 07:31:53 PM »
Just wanted to share my idea of a pin table I have made recently. Size of the metal sheet is 40 x 30 cm, and have used 200 push pins from staples.
