@jay_s_uk no only these control the tube

@jay_s_uk

@jay_s_uk and the others there are more connections like 5v, p+ gnd ......where are these connected to the duet board?

@jay_s_uk yes that's true, but there is no line from the contacts to the board and I don't want to try until it works

@dc42 my power supply is from the same manufacturer as the tube I have a diagram, but the description is in German

@jay_s_uk
Out 1 is now the output for the laser, it doesn't deliver a negative signal, does it?

further connections are needed.

1. 5V for TH

2. ground

3. I simulate the cooling.

where exactly should I connect these cables to the power supply terminal

@jay_s_uk
A technical question: How much frequency does a 40W CO2 laser tube need? In your example, is the Q value 5000? Or does that not matter.
I am new to this area and am wondering whether I am implementing it technically correctly. There were no operating instructions included, neither with the power supply nor with the tube.

M452 C"! Laser" R255 Q500;
no change. or how to use the negative output

the Duet board is configured, I use a CO2 tube. A "tool" is configured, see Config, but there is a problem, when I start up the machine, the laser is active!!!
I use the active high input on the laser power supply.

@jay_s_uk Thanks, I didn't know that this source explained it.
