The old thread wasn't nice to Bbe as the issue had nothing to do with his drivers and I couldn't modify the topic title. So continuing my thread from here. http://photonlexicon.com/forums/show...9-issues/page8
We left off here:
Trying to drive the multimode red, green and blue diodes without overdriving them (too much) inside chinese brass housings attached to chinese 10 mm optical plate with heatsinks attached below it with fans attached to those heatsinks and the diodes overheat.
According to several other users and builds they shouldn't be overheating.
We tried to find the issue via deduction. First we checked the drivers for issues, then the power cables (different AWGs), then the signal source (5V USB, ILDA from RIYA Lite), then compared collimator lenses, then with and without Lasorb connected, then with different 12V power sources (a cheap chinese LED PSU vs lab PSU vs 12V APU battery), then different LPMs and found no difference. Still overheated and produced far less power then they should. I sent the blue to Bbe and he said he got a stable output (no overheating) after polishing the housing and cleaning some junk in it and the diode.
So if anyone is building their first high power one and is experiencing this issue you might find this topic useful.
Bbe, I just got your package. It was sitting in the postal office and they were saying I have nothing all this time. Today they gave me 3 packages, one was for me and 2 packages I realized were for completely different people. You get the idea how well they do thir job.
Anyway, time to compare your blue module with mine with the actual G2 lenses since you've applied better thermal paste and polished the surface and post my results.
By the way, have you replaced the power cables that goes from the driver to the diode with thicker red/black colored one or was that me?
