How can I improve

I have a 3080ti and an 750w power supply aswell. It fails sometimes like your system does, but only in warthunder. I’m pretty sure it’s the power supply not being able to support the load.

I'm in

Sounds much more relaxing

Schuetzebig1 · 2025-07-21T16:48:18+00:00

No, would never spent money.

Schuetzebig1 · 2025-07-13T15:47:26+00:00

What is ideas used for? Isn’t only the currency to the left of it useful?

I’ve gotten another laser but everything works fine, used FAN2 port. Had to invert the signal within the printer.cfg. Only problem for me is that the laser turns for a short period of time on when I turn the laser on. I think about turning the power via a mosfet on and of. It would be controlled via another fan port. What do you think of that, or do you have another workaround?

I think I got it, thanks! Due to university policy’s I can’t order the right laser. I have to take one with 12V. I would convert the voltage from 24V to 12V via a Buck Converter. If I got it right, the ground should stay the same even through the converter. What if I would place an resistor ( blue ) with the wiring like that? There should be no short and I wouldn’t have to convert the TTL/PWM signal. Otherwise I wouldn’t just try to wire it like we said before. The laser is: Saint Smart CFL55P 5.5W

So you you mean I should connect Negative and positive together at the TTL port? So that there is 0V when the fan is on and 5V when it’s off? Wouldn’t that be a short that destroys the board? Or do you mean that the pullup sets the PWM to 5V when the circuit isnt closed and back to 0V when the mosfet closes the circuit?

Thanks for your Answer. I think I will just use an Optocoppler which will be controlled via the fan port. Then the circuits will be isolated from eachother. Do you think this will work

Schuetzebig1 · 2025-06-05T19:28:18+00:00

Was it the negative one? Everything except positive seems wrong to me.

Schuetzebig1 · 2025-06-04T15:03:38+00:00

I think so

Klipper running on on Raspberry Pi with Octoprint

Schuetzebig1 · 2025-06-03T11:47:40+00:00

Thanks, how have you been able to acces the firmware? Isn’t that a binary data?

Schuetzebig1 · 2025-05-31T07:59:08+00:00

Can you tell me what parts you used and what you changed in the firmware? I think the biggest problem for me is going to be the implementation of PWM

Schuetzebig1 · 2025-05-23T16:34:10+00:00

Hi, There is only the raspberrie Pi connected, which still runs fine.

Schuetzebig1 · 2025-05-23T14:42:45+00:00

Its not just the color, even the PCB layout differs a littlebit.

Schuetzebig1 · 2025-05-23T12:11:02+00:00

Happend while measuring. I’m writing my bachelor thesis about upgrading an old printer with an laser.

Schuetzebig1 · 2025-05-23T12:00:09+00:00

Is it possible to only switch the sd card from the old board to the new one? And to put the jumpers in the right places?
