Ok so I need to move somewhere else where there is strong socket able to handle a lot of amps to make sure if its low current the problem?Originally Posted by mixedgas
I still dont want to admit its alignment.. The packaging could not be better. A lot of bubble wrap and foam around..
@ mixedgas, The extensions is pretty long i can tell. Yes. i have a DDM with battery( 9V ). The psu has serial number 8325 and Model. 2214B-40MLA.

Hi Steve, this laser was in great shape before shipping, made 3-5mW even at idle.
His circuit breakers can't handle the inrush current of the PSU, which is why I suggested the extension cord to try and keep his breaker from tripping. It worked, but now all he's got is plasma glow.
At home I had used an extension cord to get 240v into my garage and it worked fine there. Wish I could be there to troubleshoot it myself.

Just a thought,if the seller was running it fine with 240v in his garage and buyer is running it (trying) from 120v,could this be a possible problem?
Assuming his washing machine outlet is 120v.

Is the PSU set for his input?

The mains in Greece are <240 V, maybe 220-240 dont remember, so i set the psu to HI. However, before plugging the laser i did test the psu and forgot to turn it to HI. Should I worry about the psu about this? Maybe I should try at LO?Just a thought,if the seller was running it fine with 240v in his garage and buyer is running it (trying) from 120v,could this be a possible problem?

Hi,not understanding your reply,here is my suggestion,anyone correct me if wrong,,,
1. check outlet wiring for proper voltage,polarity,ground
2. check for same results at end of ext. cord
3. VERIFY correct PSU input setting
4. correctly construct an interface to control the PSU via the port on the front of PSU
5. try again?
I'll go look again at your jumpers but I think something is missing.I have a 2213 system with a crude but working interface control that was replaced with the digital control,I'll see if I can find it to see if it matches your connections.

If this helps, the main i am plugging the psu reads 223-225 Volts.. and the psu is rated 200 V max at LO and 230 V min at HI

I would think it to be a problem as the MIN. hi input is not reached with no load.
Curious as to what the measured line voltage is when trying to run?
Sounds like the PSU is maybe starving? Probably not good for the PSU.
I would find a place with proper line voltage and current to test,thus ruling out any guesswork on the issue.

at the end of the extension cord, the voltage measures ~228 V
I mean, the ratings are right between the LO and HI modes

Go to a friends house with your argon and see if they get >230v from their wall socket, Plug it in and see if that input voltage is your problem

The pinouts are the same for 211x models. What differs is the calibration and output voltage of the low current PSU. If your controller only consists of pots and switches it will still work.
Silvershot, if you can't source enough voltage at your own home then I'd go with TTerbo's suggestion and try it at a friends house.
My shutter suggestion over at LPF is probably not the problem!
