Thanks Guys

Yes there is light, its a little dim but there is light!!

I installed the new laser power supply over the weekend and for some odd reason it just keeps blowing the internal fuse.
As soon as the power is turned on the fuse pops...

Its very strange, the wiring was exactly the same as it was before with the original power supply that kind of worked.

So another phone call to the supplier BuildyourCNC and they said they didnt know what was causing it but they would send another power supply.

Should be here tomorrow.

So fingers crossed, i will have an operational laser in the very near future!!!

I will be sure to post my victory dance when its all working!!

Cheers

Did you try hooking up a multimeter and measuring the current draw, or does the fuse pop too quickly after power-on?

The Fuse pops too quickly Alan.
This is a 220v power supply.

With the output disconnected, does the first still pop?

Hi Guys
It has been a while since my last update but i have been using the machine a lot and making progress with the laser side if things.

Well after a lot of fault finding a trying to figure out why the fuses were blowing every time i turned the power on i eventually took my laser power supply back to the supplier to have them test it for me.
I had two power supplies on hand both displaying the same issues.

I was happy to see that when we tested the two power supplies on the suppliers set up that they also blew the fuses, thismeans that my wiring is more than likely OK and it was faulty products.
We pulled a new power supply from their stock and tested that and it also blew its fuse!!!
They must of had a pretty bad batch!!

We decided to try a 110v version of the 220v supply i had an it seemed to hold up just fine so i took that home and installed it and Hey presto i have a working laser cutter!!!!

So now it was time to test the laser and figure out some power settings and feed rates for different materials.

All was going well and i had dialed in the settings for Dollar Tree Foam board and was moving onto 1/6th and 1/8th ply.

I decided to cut a few ballerina's for my daughter and noticed the power was dropping off after a couple minutes of run time.

Further tests also revealed that i could not cut through 1/4 inch Acrylic at the feed rates and power setting shown in their demo videos. I could also not cut through 1/8th or 1/16th plywood....
So after a phone call to the supplier it seems i also have a defective Laser tube.....
They have had a few occurrences where the laser tubes are nut fully filled with CO2 resulting in a lower power output.
They immediately told me they would send a replacement.

I have a new laser tube on the way it should be here this evening!

So finally i will be able to start production of my frames in the near future.....
Fingers crossed....


Even though i have had a lot of issues with the laser side of my CNC machine, some of them self inflicted, i must say that i have received top notch support from the supplier BuildYourCNC.com
They have been very helpful over the phone with fault diagnosis and are more than willing to help me in person when i got o visit their facility in Katy, West Houston.
I would still be very happy to recommend them if you ever decide to go the CNC router or laser cutter route.
In fact next year i am planning to try out one of their 3D printers.


I will be sure to keep you posted about how it all turns out.


Cheers
