I bought a NDB7875 from DTR a couple of weeks ago. I am using it for laser engraving. I needed the extra power over my M140 to speed up some of my engravings. 7875 is the 3w everyone else seems to use because of it's relatively low divergence for a 3w / 9mm. Emblazer (laserblade) uses them as...

Several of us are looking to use DTR's new 6 watt diode for full gray scale engraving. The issue is with the standard lenses G2, 3 element, and J-Tech lenses can't get it focused small enough. Right now it only gets to 0.3mm / 0.012" and we need it to focus to a minimum of half that to be usable...

Hey I have one of DTR's 2w M140's already mounted in one of the standard copper modules. I mounted the module in one of Z-bolts heat sinks. What I don't know is, what is a safe temp measuring from the copper module? I left 1/8th of an inch of the copper module peaking out of the heat sink so I...

I am trying to get my Flexmod P3 (Interlock) setup for my laser engraver. I have 2w M140 from DTR. The issue I am having is the FM goes into protection mode if I go over 1A. I am using a dummy test load 6 diodes and 2w 1ohm resistor. I am measuring mv across the resistor to get the ma. I am...

I wanted everyone to know that Innolasers has Flexmod P3's in stock and is shipping them now. I ordered mine yesterday and it has shipped already. I am am sorry if this is the wrong place to post it but I can't post to the buy, sell, trade yet and thought people would really want to know.

Hey all, I am in the process of making 2'x3' laser engraver. I bought an m140, housing, and G2 from DTR. I plan on doing the 8 bit laser engraving which mean I have to have an analog/ttl driver, but I am having issues getting a hold of a flexmod P3. They seem to be sold out and on back order . I...
