I purchased an LED DC 100mA meter for my laser cutter when I got my X7 just getting around to hooking up meter
Four wires - red, black, green and blue. Anyone know where they go?

Re: Instructions to hook up LED DC 100mA meter
I guess you also have a datasheet for it.. probably one wire is the +5V(red?) one GND (Black?) one current in/+ (Blue?) and one is Current out/- (Green?)
Check your info..
Then connecting it:
If your LPSU has a +5V connection you can connect the Red(?) wire with that. The Black(?) GND goes to the LPSU's GND. The current in(+) goes to the lasertube Kathode (Near the laserbeam-exit) and the current out/- goes to the LPSU return wire (often a thin blue or red wire)..

Don't recall getting a data sheet? Can I find it online?

Re: Instructions to hook up LED DC 100mA meter
I think he found out already.. The colors i mentioned are OK.. I found a picture of it and indeed, i was right..
So:
Red: +5V (can be retreived from the LPSU/+5V)
Black: GND (can also be retreived from LPSU/GND)
Green: IN- (goes to LPSU returnwire)
Blue: IN+ (goes to Lasertube/returnwire)
When this meter comes with a Shunt-resistor (normaly with a very small value, maybe even 0,1 Ohm) you have to place that between the Green and Blue wire
