Hmm, nije nemoguce, mozda je to neko vec radio, potrazi malo.
Za taj DVB-T2 sigurno koriste one iste IC koje imaju i u RTL-SDR a za to ima SW.
Pokusaj iskopati informaciju koji chipset IC ima unutra.

Ova prigušnica se vrlo lako može prepraviti na vodeno hladjenje ...

CNC router VCT4030R , sa komandnim modulom  RichAuto-A1X i softverom UcanCam 10.5 neće da radi dobro.
Krug izgleda ovako. Kontaktirali smo proizvođača par puta, bem li ga šta će na kraju da rekne. Ima li neko pojma
o ovom problemu? U protivnom ništa od prednjih ploča.

Ili problem sa drajverom, "prokliza", mozda je prebrzo podesen, mora da se proba vise puta na razlicitim koordinatama i sa razlicitim Feed rate.

Nisu to luftovi, mada i oni umeju praviti probleme.

To pre liči na problem sa motion controlerom na toj mašini.
Koliko se sećam kada je Branko kupio tu mašinu, bilo je reči o USB konekciji prema PC.

Upravo u tim USB kontrolerima može ležati dosta problema, jer se upravo u njima
vrši konverzija G koda u Step/dir impulse prema drajverima.

Velika većina tih USB kontrolera je "nedoradjena" jer to što moraju da izvrše nije ni malo lak zadatak.

***

Mach3 je recimo prešao dug i trnovit razvojni put da bi na kraju bio "sasvim upotrebljiv" softver bez nekih
posebnih grešeka u radu. Mnogo je bilo medjuverzija i revizija dok se nisu popravili svi bagovi ...

Mach3 je u izvornoj varijanti predvidjen za LPT port, i to tako radi bez problema.

Već kada se na Mach3 prikači neki USB motion kontroler, koji tada preuzima svu interpolaciju na sebe
Mach3 ostane samo kao "go" ekran koji šalje putem USB konekcije linije G-koda , a ti kontroleri dalje na sebe
preuzimaju "sav posao".

I eto problema, ako nije USB kontroler uradjen kako treba. Imao sam priliku da vidim neke USB kontrolere
za Mach3 koji nemaju akceleraciju i deceleracijuz prilikom kretanja motora i niz sličnih propusta ...

***
Naša domaća firma iz centralne Srbije je skoro izbacila na tržište jedan takav USB kontroler za Mach3.
Nadam se da su sve uradili kako treba, inače će imati dosta reklamacija ...


===
Branko, ne mogu sa sigurnošću tvrditi štra je kod tebe uzrok, ali vrlo je moguće
da imaš gore opisani problem.


Postavi tvoj g-kod od tog kruga da ga pogledam.


P.S.
Kako izlaze recimo kocke, jesu li one pravilne ?

Krug na CNC je isto sto i XY prikaz na OSC, vidi se "linearnost" i krug je zanimljiv slucaj sto ima dve ose fazno pomerene koje idu od min do max i natrag i tu se menja feedrate od npr 1000 do 0 pa zatim promene smer pa opet ubrzanje.
Kroz takav raspon "frekvencija" ima jedna mala "crna rupa" ili rezonatna ucestanost motora i to da ne verujete uvek je tu gde najvise problema moze da napravi, u toj tacki motor prokliza i ne moze da se predvidi gde ce i koliko da ode, ode "random" 23 koraka i tome slicno … Dakle probaj prvo smanjiti feed rate. Da li kontroler moze brze ili sporije to moras da ustanovis, ako "baguje" stalno pri bilo kom feed rate onda postavi G-CODE da proverimo sta je stvarno zadato da se nacrta?
