Liaison USB CURA vers JGMAKER magic

[Alain_D 3]

Avec un câble USB, j'arrive à piloter avec Pronterface les axes de l'imprimante (et sûrement d'autres choses que j'ai oublié de tester), mais impossible d'établir une connexion entre CURA et l'imprimante, je dois passer par une carte SD pour imprimer.

Cela ne me gêne pas plus que çà, l'imprimante tourne quand le PC est éteint, c'est bon.

Mais j'aimerai quand même bien comprendre pourquoi CURA ne "voit" pas l'imprimante alors que je n'ai aucun souci avec Pronterface.

J'ai essayé avec différentes version de CURA sans succès.

USB support in UltiMaker Cura is considered legacy.
UltiMaker does not recommend using direct USB.

Ok, I understand that and I don't want to use the USB cable, but I would like to know why it doesn't work.

I like to understand why (and how) things works or not...

It doesn't work because the code base to maintain it has not been updated in years.
Changes in windows, linux and macos operating systems have happened  and UltiMaker Cura was never updated to compensate for the changes..
Additionally 3rd party manufactures use dozens of different chipsets for communication with USB and UltiMaker Cura was never updated to interface with those.

Lastly - UltiMaker has not made a new 3d printer with a USB client port on it since 2016.. and even back then UltiMaker realized its not a viable way of 3d printing and was already saying dont use it on their own printers.
Because UltiMaker has not made a printer that used USB printing in so long they have not put any effort into updating USB support in UltiMaker Cura.
Only other way updates for USB support would have been added is if the community contributed code updates for it.. which has not really happened either because everyone from the community that helps with the code,  knows using USB to print is a horrible idea.

So - Your chances of USB working or not is a flip of a coin.. and even if one printer works different one might not.. and even if it works on one computer it might not on a different computer.
