Hello folks, yeah right. I am missing some current on my driver. :). After I killed my DVD diode while engraving filled areas (30min-1h constant power) @ 300mA I ordered a new LPC 826 from Odiforce. (+ copper module) Before I plugged it onto the driver I applied my test load. The driver in...

Nice to read. Had the same questions. They are now nearly all answered. Compnents: LPC-826 Copper module Aixiz housing Aixiz Glass Lens Adj Driver 80-500mA The copper module might be oversized for this red diode but I killed my old DVD burner diode @300mA. I guess the internals are molten. So...

Wow this is an answer ! Thank you !

I would rather stay with those SCC DVD burner or LPC-826s. Just my opinion. But about my question above ? Could you tell why I fried my diode ? 1) I drove it at 300mV/300mA for long and excessive area engraving. 2) I maybe could have re-plugged the laser diode to the board without prior...

I have another update in that matter. I made several test runs with different feed rates. See pictures You might wonder why I havn't finised the test series. I drove the diode with 300mV / 300 mA. This is a bit to much for a DVD burner diode I guess. Found out that this kind of diode is...

UPDATE: I reduced the engraving speed to <100mm/sec and from the first looks of it that fixed the false lines. The areas are now perfectly engraved. I guess I could put the metal board with its magnets back in.

Yeah Cyparagon, I guess the relay really is a problem. I will try to replace it with a FET. Onther thing I did not mention. As work surface I replaced the wooden board I had first with a trimmed piece of metal from an old pc case. I used neodynium magnets to hold the work piece in place. The...

I am a bit overwhelmed by the abundance of drivers here. The above driver should work without flaws but my built doesn't. However the shield has an external driver connector. Maybe using this jumper I could try another driver. I already built the one from Life long experimenter - It can be...

Thank you DTR. I just finished a test run with a 1uF cap. Didn't fix it. I although put a folded aluminium layer between the shield and the arduino. Isolated with two layers of duct tape on each side. This did not fix the problem either. I guess I have to rebuild the shield. Maybe some...

The speed varies from 50mm/sec (engraving) to 500mm/sec (feed). Those numbers are quite theoretical I think because 500mm/sec are pretty fast and the actual movement speed seems to be below that. Anyways these are the software settings and the caligrated values are pretty acurate. This is an...

wrong forum sorry !!! could someone please move this to the "Drivers" subforum ? I skipped over it. Sorry

Hello folks ! I recently have completed my laser engraver with an dvd burner diode. It runs at 300mV blabla. But I have a problem with it. The driver is made by groover. This is the schematic and the layout. However I have some issues. And I guess it is because of the driver. I mean how I did...

Take a look at this indie game. Its free. I nearly shit my pants. So did the guy in let's play video. It is german but you can tell by the sound of his voice what he feels. This is what I call scary SCP-087 - The SCP Foundation Let's play: Let's Test SCP-087

I cleaned this thread up and did what you suggested. Sorry for rushing in.

Hello all. I made a liverwursted start here so I am trying to iron this out here :) . My name is Sebastian. I am from germany. I am aka ianmcmill on the internets. I am studying chemistry and english. Before I worked as a chemistry laboatory assistant. Some day I will be teacher. Hopefully :)...

I am sorry. Gonna clean this up.

Hello guys ! Sorry. I Don't know if this is the right forum section. I recently finished my Frankenstein Laser Engraver/Cutter made from old PC junk and put together a tutorial. I stumbled over a tutorial about how to build a laser engraver out of dvd drives. This build has been talked about...
