Laser Output

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

@Macwolf thats the same as PSU type 1 shown in the wiring diagram on the page I linked you to earlier (https://github.com/TeamGloomy/LPC-STM32-RRFUserConfigs/tree/master/K40 CO2 Laser - SKR 2 - ESP - paulg4h) so it would be wired in the same way i.e. to heater ground

@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

[jay_s_uk]

@Macwolf to the "L" connection like the PSU type 2

[Macwolf]

@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]

@Macwolf which others are you talking about?

[Macwolf]

@jay_s_uk

[jay_s_uk]

@Macwolf do you see those connected anywhere on the PSU type 2 to the SKR2 board?

[Macwolf]

@jay_s_uk no only these control the tube

[jay_s_uk]

@Macwolf ok then. so you just need to connect the "L" connection to the duet. You will need to connect a ground connection, like on PSU type 2, to your power supply powering your duet
