Arduino card mega 2650 bricked

[g4l0up]

Hi everyone,

i'm new, i get a witbox 1 ( 3D printer ), but i bricked it on cura by not finish a firmware, now i'm stuck because i can't reinstall the fw,
i installed arduino ide, try to reset or i don't what. but im not a pro.

So i need to get my card detected by cura software as before.

I'm not familiar with your witbox 1 or with cura.

1. Do you get error messages when you try to flash the firmware? If so, which ones?
2. Do you have links to user manuals for the printer and cura?

Is you Mega still recognised by your operating system?

Your problem does not indicate a problem with the IDE and hence your topic has been moved to a more suitable location on the forum.

hey ty for answered,

i have this ( in picture )
board info :

upload info :

bootloader info :

so i can't use the board as i want, and also the board is connected to an another card but i don't think it's also a mother card part, only the mega 2560 need to be recovered

manual in french
Cura software

and when a plug in my pc i have com3 ok but i don't know how to know if is still recognised

The VID and PID indicate that your board has a FTDI serial-to-usb adapter; see https://devicehunt.com/view/type/usb/vendor/0403/device/6001. It's unusual to find Megas with that chip but not impossible.

The fact that you get a COM port when you connect it indicates that Windows recognises it.

It's a bit much for me to dig through a French manual, sorry for that. I can't promise when I give that a try.

Hi @g4l0up. There is a known bug in Arduino IDE 2.x that can cause uploads to fail with this "Access is denied" error if you try uploading to a board using an FTDI FT232R USB chip while the Arduino IDE Serial Monitor or Serial Plotter is open.

A port can only be used by one process at a time, so Arduino IDE must automatically close the port in Serial Monitor and Serial Plotter during an upload, automatically opening it again after. For some reason, that juggling of the port control is not working with boards that have the FTDI USB chip.

If that bug is the cause of the problem you are having, the workaround will be to manually close the port in Serial Monitor/Serial Plotter before doing an upload. Please give that a try and then let me know if you still have the error while uploading:

Serial Monitor

1. Click the X icon on the "Serial Monitor" tab in the bottom panel of the Arduino IDE window to close the tab:
   
2. Upload the sketch.
3. Open Serial Monitor again if needed (by clicking the icon on the IDE toolbar or the Tools > Serial Monitor menu item) after the upload is finished.

Serial Plotter

If you have the "Serial Plotter" window open, the procedure is a bit different from closing the Serial Monitor connection:

1. Close the "Serial Plotter" window.
2. If the "Serial Monitor" view is not already open, select Tools > Serial Monitor from the Arduino IDE menus to open it.
   ⓘ We must do an open/close cycle on Serial Monitor as a workaround for a bug in Serial Plotter
3. Click the X icon on the "Serial Monitor" tab in the bottom panel of the Arduino IDE window to close the tab:
   
4. Upload the sketch.
5. Open Serial Monitor and/or Serial Plotter again if needed after the upload is finished.

Please let me know if you have any questions or problems while following those instructions.

Merci pour votre réponse j'essaye ça ce soir, cependant je ne suis même pas sur du croquis à installer, c'est pour une imprimante 3d witbox
