paulkruger you ever have any luck? Mine was DOA and never heard a word. This business listed in Cleveland Ohio, is on my way to work. Edit: No, i'm not looking to cause any trouble. Would be nice to know if there was a source of them local. Based on what they say they do at this place, i...

If you get suppression MAKE SURE YOU ENABLE IT FIRST....despite it saying "enable" or "option", its apparently mandatory.

Lightning stalker! Very nice work! Is that Altium Designer you're using for the 3D renders? And how the heck are you soldering those SMD parts? I'm guessing there's very little for safety of the diode in this design? How is the current set? I know theres the trimpot, but is it set by putting...

Right, thats the new and updated one using a digital pot. I dont think its that complicated, the first schematic is surely simpler than what i posted. What i posted is what they originally were using. My only issue with that new one is, that digital pot is hard to solder! The second layout...

Cyparagon, They are. I've attached the old suggested schematic from PicEngrave. They use 2 counters and a resistor network. My use of the FPGA was simply to replace the 2 counters. I could also add things like reset, which they have on most counters. But i could even offer some digital feedback...

I do have a scope thankfully. Where are these at? i did some digging but couldn't find much. Also how small are they? I'm not the best at SMD components, hence why i had some more experienced guys solder up my Flexmodp3. Luckily its their job to do that stuff lol. The DAC is my own design...

The older one, with 2 BCD up down's, isnt that bad. The resistor network is required to get the different voltages between 0-5V, and they use 2 4bit counters because its pretty tough finding a single 8 biit up/down. Its actually easier since the machine steps are the clock source. If you're...

Hi Lighting Stalker, 2A max. This is just a single M140 445nm blue laser diode from DTR. The goal is greyscale picture shading on my CNC. Needs to have analog modulation. 0-5v is great, but, i know i could work with other voltage ranges.

I know exactly what you're trying to do. I'm in the same boat, but, my Flexmod doesnt seem to work. I'm a bit peeved about this. FPGA - Field programmable gate array. Basically, you design hardware via software. Theres only one major package out there for this, PicEngrave. But, realistically...

Just heard back from Junktronix. Says hes pretty sure the M140 diodes dont have photodiodes, which is fine. But told me itd be figure 9 in their data sheet that would do the right setup. So i think i'm gonna pull the trigger on this, unless i hear randomly for the good Dr about the flexmod.

Bionic, cool man. I would def want to use the photodiode feedback. I have one of DTR's 445nm blue laser diodes. I assume the unused wire is the photodiode? Also, any idea if these 445nm diodes are Type A, B, or C? Thanks

Guys. I come defeated by the Flexmod p3.3 It refuses to go into Gain current. No response from customer support...... i deal with industrial/Automation equipment for a living, so, this is right up my alley. http://www.teamwavelength.com/downloads/datasheets/pldseries.pdf Curious if anyone...

Curious what you are doing for a DAC. Im using an FPGA/CPLD over here

Alright guys, figured i'd stop hijacking one of the previous help threads. DKumpula has been great help on there (thanks man) But I'm stumped. I originally set it up as per instructions, and got the red led, just by placing a meter across the load, set to current (mA). Ok. As DKumpula...
