Hi,
I am trying to upgrade my 5th gen for more power, installing a second PSU (for now of 60w).
I took a look at the PDF for the 90w update and the unofficial wiring diagram from scatterplot (really apreciated!) and I was pretty confident I could do it so ordered a 60w PSU from aliexpress

I received it and (no surpris) it look different from the pictures and the product description.

The description showed a PSU with 2 set of connectors (3 and 6 pins) and a red and white wire to connect to the laser.
I received one (MYJG60s) with 4 and 6 pins connectors (L-,FG,AC,AC and H,L,P,G,IN,5v) and only the red wire for the laser.

Sure is a very noob questions, but the white wire is the return wire for the laser as far I know. In the confirguration I received it should be connected to the L- pin, is correct? as is in the original 40w PSU.

Thanks!

Did it come with a hookup diagram or anything? It's kinda hard to say totally 100% for sure. You may want to ask the seller for a manual or something, or see if you can find the manufacturer online and ask them for a manual.

Here's my total guess on the hookups:

L-: Laser ground
FG: Frame Ground, used for both your AC input and your laser frame
AC/AC: I don't know how your AC lines are wired in Spain but it's probably the input power, two different legs

H/L: High and Low signal input connections to use if you have an active high or active low signal from your controller. I can't remember what RE is off the top of my head.
P: Probably the protection circuit
G: Control ground
IN: Power level control signal
5V: Output of 5V for control pendants or panels or something?

It's worth noting that the 6 pin connector appears to be the same as the one I have but with slightly different letters- mine was HL, TL, WP, G, IN, 5V, but I bet they do the same thing. I'm not at home right now but if you want I can take a picture of how mine's wired up later tonight.

Laplace,

I created an unofficial wiring diagram for my GEN 45W you can find it here

Hope this helps

Thanks a lot for so quick anwsers.


They send me a generic diagram. https://ae01.alicdn.com/kf/HTB1W8FPNFXXXXciXFXXq6xXFXXXe.jpg But it do not show other connectors my PSU has and shows a dedicated return wire not present in the one I received.
The pins meaning as more or less clear. Also I think I know how to connect most of them
But in the Unoficial wiring (and checking my machine) the return blue wire from the negative side of the laser goes to the control board and after a orange wire goes from the wire to the F- connector in the board.

In the 90w upgrade PDF the return blue wire from the laser goes again from the tube to the board but in this case the orange wire goes to an specific return wire (not a connector) in the PSU (which only have FG,AC,AC connector)

Thats why I think it should be connected to the F- in the case of the 60w PSU

But the chinese suplier after a lot of mails sending me the same incorrect diagram said that the negative wire from the laser must be connected to FG, but I simply do not trust they really knew (after how they answered my first mails)

I believe the blue wire going to the RE board and back to PS via orange wire is how FSL is measuring and displaying
the tube power in mA.

The stock power supply from FS has a 24v supply in the same case for stepper motor power, most replacement generic supplies don't have this extra set of taps.
You will need a separate 24v supply in addition to the generic supply

I am keeping the original 40W PSU for the 24V and 5V.
My idea is to install a second PSU only to power the tube, as is done in the official 90W upgrade kit.

Well. It worked!!!

I just installed the second PSU and at maximun power it gives an output of aroun 24mA compared with the 14-15 mA or the 40W one. Also nothing exploded or set on fire so it looked a success.
I tried with my old 40w tube that was dying anyway and now I will order a new 60w tube.

If everything keep working together I will made a better description of how I connected everything.


Thanks for your help, the wiring diagram and feedback allowed me to try this.
