T2 Engraving / T2 pop out window for laser control
« on: August 30, 2019, 08:16:03 AM »
A keyboard input was posted many moons ago about how to get T2 pop out windows to open in the same place everytime?

Does any know the keyboard input for that on windows 7? Would work on dual monitors where the pop out window would open on a secondary monitor?

Google was not much help with this question

always impressed with your work and creativity

as mentioned color affects the abilities of the laser.

Etching anondized aluminum (black) was one of the first things I did with my 2500mw eleksmaker; high power and slow speed.

Forget the 16V, too low for a 12v input. I suggest replacing it with a 25V or 35V cap.
Same value is ok, but look for a 105C low ESR cap if you can, preferably a decent brand.

Although not totally needed in this case as the supply also has caps and the input should be well regulated, however it is fed by a switch mode so any noise escaping the supply will be high frequency, then it has multiple switch modes running off it so it needs a low esr and since it is supplying multiple motors with high frequency pwm signals has substantial AC needs, so a good cap here eliminates a lot of noise from the entire system.

There are two cap on the mana se board, could both be replaced with 24v or higher?

3D Printer Software / Malrin for monoprice printers

@Zax  This is posed to you as you appear to have the aptitude and know-how.

What would you require to create a marlin based firmware for the monoprice line of printers, if you were interested in creating a firmware to be released to the general public

Engraving / Re: Engraving Anodised metal

Hi guys,

I was wondering if anyone had any luck with engraving anodised materials?
I am designing some coasters out of anodised aluminium with personal foto's or logo's.
After testing with blank anodised aluminium (not colored) i didnt have much success.

Settings used:

laser power 255
feed rate 1000
resolution 0.1

Software: T2 Laser

Laser: blue laser module 16W from bangood https://www.banggood.com/16W-Laser-Engraving-Machine-Can-Engrave-Metal-Powerful-DIY-Metal-Printer-Engraver-220x250mm-p-1280615.html?rmmds=search&cur_warehouse=CN

One of the first things I did was etch anodised metal. It worked out nicely.

Power = 255
Feedrate = 300 - 400
Resolution = 0.1

Then this may make sense.

First mirror I laid it on my burned MDF board and the burns on the board came through.

Put it on top of a white sheet of paper, and got those lines.

Placed it on a piece of ply and it looks MUCH better.

Having it running at 2500 diagonally and its looking smooth.

I have complete about 10 laser jobs on mirrors.  I keep the mirror about 3mm off the surface of the table. I think what is happening is what I will call a double burn - where the laser is burning two surface. Try place scrap pieces of craft plywood or coins to keep the mirror off the table.

Also read up on adjusting the current limit. BTW - plugging it in backwards will fry the device. Don't ask how I know >:(

I thought it might be the current, but I have had the current set on the X for over a year now, will check it again.  As for backwards...well, uhhh Of course I did not put the one pictured above in backwards, never, absolutely could not have did happen.

Good news is it is a relatively cheap easily replaced module. I keep a dozen in stock

I think I will have to do that same, get a some for backup stock

I remember reading in a model mag,   a chap advising people buying RC  transmitters to give them a good shake.  remove the back..turn upside down and shake again..... AND  watch the bits of wire and solder fall out from the board inside!!.....
Mind you..it depends in your case where the board was stowed...it might have picked up moisture...and POUF!!

I do not think moisture would be an issue, as I am in a dry climate.  For swings and round-abouts, I connected two drivers to the board, plugged in the USB - got the green light. Plugged in the power, turned on the power to the board, and within seconds the X axis drivers IC was so hot to the touch that is almost blistered my finger.

Any ideas on what would cause it to over heat within seconds of receiving power?

So hooked up an 2 axis mana board that I had not used for about year. Plug everything in, all lights are good. Start to smell what smells like a computer that has been running for a long time. The smell gets stronger...something inside tells me I should be worried. The smell gets stronger and a little because I cant figure what it is ....... POOF
