TH and TL weird behaviour with power supply and lasercad.

[pannaus]

Hi guys.
I have a X7 connected to a 150W powersupply and a 150W laser tube.

I had the setting TTL Level on: Low Level effective, but the TTL wire from the PSU was actually plugged in the TH. Altough the display on the power supply indicated A 0, meaning everything was fine, when I tested laser from the X7 panel, the laser would fire but would not stop when i unpressed the button.

Thanks to some info found here on the forum, I checked the PSU diagram and found out that the TTL was on TH and not on TL.
So I unplugged the TH and plugged the wire into the TH, leaving the LOW LEVEL. The laser now behaves normally, but the display on the power supply shows L 0, meaning it has no laser connected which is false as the laser fires and works perfectly.

Any suggestions?

Thanks!

It would help if you told us which power supply you have. Make and model.

And, if it's working correctly, do you really care?

I just dont want to screw something that' s all
The model is myjg 150w. That's all there is written on the psu.

Also, do u know if it's possible to set um/pulse lower than 1 on laserCad?

Thanks!
