K40 new power supply wiring without DSP upgrade
Posted: Sun Oct 30, 2016 3:30 pm
I purchased the following LO Power supply to replace the stock one. I have looked at the forums and not seeing any wiring diagrams to see how I would do this. I am currently not upgrading to a DSP controller just replacing the power supply. Since the LO power supply does not have a 24v supply I have a separate 24v unit. I am not excited to wire it and have the machine blow up on me so I am asking for assistance. Attached is a photo of my old PSU.

The connections on the old PSU are:
1st block of 4 is
1) to ampmeter
2) Ground
3) to main power on/off switch
4) to main power on/off switch
Block of 6 is
1) to laser on/off
2) to laser on/off
3) TTL to laser test button
4) GND to laser test button, purple is joined to it and goes to potentiometer/rotary left
5) IN to potentiometer/rotary middle
6) 5V to potentiometer/rotary right
last bock of 4 is to M2Nano board
1)24v
2)Ground
3)5v
4)L
The new power supply has:
FG AC AC TH TL WP G IN 5V has Ground in back of PSU
I have tried following the diagram in this link as a guide. But I am just not comfortable turning the machine and have it go up in smoke.

So here is what I am was thinking maybe someone can verify my connection
New LO PSU to (pin) connection on Old PSU
ground/negative back of psu to mA Meter
First set
FG >>> Ground
AC >>> (3) power on/off
AC >>> (4) power on/off
Second set
TH >>>
TL >>> L(M2Nano board) & (1) laser on/off
WP >>> (3) test button & (2) laser on/off
G >>> (4) test button & (4) potentiometer
IN >>> (5)potentiometer
5V >>> (6)potentiometer & ((5v)M2Nano board))
M2Nano connection
24v >>> to POS terminal on 24v PSU
G >>> to NEG terminal on 24v PSU
5V >>> to 5v on LO PSU
L >>> to TL on LO PSU
Thanks in advance if you can make sense of the above and able to give me feedback.
