That could explain why the lava drive 4 or 5 did not do that. You're stating that since I've grounded the diode at the diode ot heatsink point of the aixiz module, this is somewhat different than that of the lava drives 4/5? Odd, I've used atleast 5 of these boost drivers and had a couple made and sent to me hot by jayrob. They ALL had case negative. I'm at a point, unusually, where I'm challenged
Yes it's different than Flex.
First allow me to apologise for ruining your sale and this thread.
Then, you need to disassemble the laser ad immediately stop using it.
If you read the MicroBoost manual, you will find that it's different from FlexDrive in one crucial detail -
There are no common points between input and output. FlexDrive's negative connection is continous. MicroBoost's is not.
If you shorted the case pin and any other pin of your diode, you are exeptionally lucky it made it out alive. A member (well, noob) here once destroyed $400 worth of diodes (2x 12xBR back then) because he shorted case and negative pin of diode. No feedback loop was made back to the driver which simply kept boosting the power.
Disassemble laser, connect case pin to the negative input ONLY, and have negative to negative and positive to postitive properly wired if they are not already.
Positive input is made via spring.
That's a case negative build.
If you want case positive , solder spring to negative input of driver and case pin to positive input.
Better idea is to use a contact switch board like in Cree C6 case, where the battery hits only the contact board and not the driver - hence, diode's pins, which can bend and break.
EDIT- addendum, two CR123's work ? I do not think so. You most likely bricked the driver and it's directly connecting the batteries to the diode. Read manual:

That's 5.8 V MAXIMUM input voltage, otherwise magic smoke comes out of chips there.
It's a good chance that it already did. Test your driver first, before doing anything else (except complete disassembly of laser).
If in need of moneys, try selling the host alone. It's a kickass host.
