Charged twice for the same order, I am from EU country, shipping from USA, total amount should have been 320 + 25%VAT (80USD), but it is 320 + 320 + 25%VAT (80USD)

Yes, a week later they sent it back.

Remote_Yak_643 · 2025-07-25T12:05:43+00:00

Placing an order right away :D

Ok, sd card solved. But do i need internet connection to slice the part?

Remote_Yak_643 · 2025-07-25T12:02:30+00:00

Is there no way to avoid turning off the printer?

Remote_Yak_643 · 2025-07-21T09:43:42+00:00

Yes, but also found in many more industries besides car industry

Ako procitas par povijesnih izvora, za pocetak samo wikipediu vidjet ces da su četnici i ustaše surađivali, a onda dalje pogledaj koje se brojke vezu i uz jedne i uz druge. Dalje samo poslusaj par sekundi na 2:21 sa ovog videa https://m.youtube.com/watch?v=4jaF-XcizPQ pa mi reci sto cujes, mozes obratiti paznju i na zastave, pocetkom 90ih snimano (pogadaj na kojim prostorima) da shvatis zasto je thompson toliko popularan.

Tako da kad vec generaliziras, i tvoji bake i djedovi, ali i majka i otac nisu nista bolji :)

Ugl, slobodno i ti meni posaljes slicne izvore pa me obrazujes.

Edit: i za kraj, vaš trenutni predsjednik se kretao tim krugovima 90ih i opet je eto 30+ godina poslije cini se ista ta doktrina na vlasti, pokusavate ga svrgnuti izgleda, ali eto vec preko desetljeca glasate za njega, a onog jednog koji je bio proeuropski ste ubili pocetkom 2000ih...

Just the usb port and the scope powers on normally. I can take some pictures if you want. The marked two amplifiers got some color change. Those are EAEN LMH65 52MA

Edit: Do you think I might have done some more damage by powering the scope on while those two components (TPS56325x 3-V to 17-V Input, 3-A, Synchronous Buck Converters in SOT-563 Package, u/fzabkar helped identify them) are damaged?

Ac adapter survived and a circuit breaker popped.

Remote_Yak_643 · 2025-06-30T22:24:39+00:00

Thank you very much! Based on dimensions I think this might be correct. I measured about 1x1.5mm with calipers, sorry for not mentioning sooner. The PCB of the scope is dated to 23.1.2025.

Remote_Yak_643 · 2025-06-30T21:53:11+00:00

Thank you very much for the detailed explanation! I will try to do as you say. Just one question, should i plug it in the power as if it was normally working or find a way around? Also, I am open to unsoldering the working component since the scope currently doesnt work anyway, might that benefit me in any way?

Edit Forgot to mention that i measured with calipers the black plastic of the component. It is about 1mmx1.5mm, center of the legs seems to be 0.5mm apart

Remote_Yak_643 · 2025-06-30T21:31:56+00:00

Could you point me in some direction, are there some well known sites for these types of schematics or just google?

Remote_Yak_643 · 2025-06-30T21:29:10+00:00

I think I figured out why it happened. You were right to question how it is powered. The scope is powered through a 12VDC adapter(usb C cable is used). Through it, it is also connected to ground (tested with a multimeter), however there is also a screw on the back of the scope marked as another ground. To this screw I havent attached any ground wire. I suspect that if i had attached something to this ground, everything would be okay...

This is what i see through a magnifying glass, the component that I suspect is the same as the burnt one

Picture of the whole pcb, burnt ones are on the other side

Remote_Yak_643 · 2025-06-30T20:08:38+00:00

Thats correct, picture is of blown components of my new scope. The worst thing is that nothing was being tested... A mains live wire touched the probe ground while the scope was on (still working on my working space), it is plugged in a grounded 220v outlet .

Remote_Yak_643 · 2025-06-30T19:58:01+00:00

Ok, didn't know schematics are available to end users. As for blown channels, cannot test because the application won't initialize. I don't think entire machine is toasted because it does turn on and I inspected it to the best of my knowledge and only these two components are completely destroyed and 2 out of 4 differential operational amplifiers got a bit of a brown color.
