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.

@T3P3Tony many Thanks is OUT 6 in the documentation

Hello, I have a Duet 3 XD and the "Laser, VFD..." connection is a mystery to me. How is this pin addressed? Is it an "OUT"? Unfortunately, it is not mentioned anywhere in the documentation.
Thanks

Hello
duet has a scanning Z probe on offer, my question about the product is, can you use it as a "Z-endstop"? otherwise there would be 2 probes on the print head. one for bed mesh and one as an end stop.

Thanks for the answers, meanwhile the highest value is 0.3mm, I drove off the top of the top plate

with a dial gauge, the Y rail is at 1-2/100. the bed is warped from the middle of 3/10.

Thanks Markus

@deckingman hence the question of whether the bed is crooked or something else, the Y rail (CBC) is mounted on aluminum, according to the height map the aluminum should be warped. if it's not the bed.
