@bearer said in Repair servive in Europe/Germany?:

Allegro A4403GEUTR-T 5v

Hi Guys,
I think I am a step further. I took of the damaged part from the pcb with preheated pcb and some non-celan flux. So far so good. I've ordered now some replacement and I now I am not shure how to orientate the new one. Is that a flatened corner marked on the pcb which should be on the same spot of the replacement?

@bearer didn't checked that befor, it works with usb connected, think it's a good sign. So do I have to replace only the marked part? Is it possible to do it on my own. Where can I get this part from?

@insertnamehere thx for the info, didn't know that

Hi Guys, I destroyed one of my duet 2 WiFi. I shortened ground to something, I found a damaged component on the pcb as you can see on the picture. Is it possible to repair?

Best Regards Cai

@dc42 I'm an idiot and so fucking stupid. It was 100% my bad. I upgraded directly to the latest release 3.01-RC4 and skipped the step to first upgrade to Version 3.0.

Now it seem to work perfekt. Temps are correct.

It's so embarrassing. Hope you all can forgive me. Sorry for taking your time.

@dc42 I measure excactly 3.3V on all three channels and temp stay on 2000C. Do you have a presumtion what the Problem could be?

@dc42 I measured a value of 1.1-1.2 ohm and I still get 2000°C readings with just USB power applied.

@Bakak @dc42 I don't get it, what fuse can I measure and what should the value be?

@droftarts I'm using the latest release of ReprapFirmware 3, upgrading was the first thing I did. All other things works just perfekt.

@Danal with unplugged sensor it also shows 2000

@dc42 what could I do to test, what is the problem?

Thanks to all so far
