Constructie cnc din lemn(Tego)

Si daca scoti arduinul din soclu in aer si te joci cu el asa, se mai deconecteaza ?

[bobinatorul]

Da asa făcea si inainte sa il pun in soclu.

Fara surse alimentare fara nimic.

Am crezut initial ca face microusb-ul figuri,am luat unul mai calitativ ,se si simte ca sta mai bine in mufa dar nici o diferenta.Eee cand merge cand nu merge.

Diferenta intre cele 2 arduino este ca cel cu probleme e negru cu microusb iar cel bun albastru cu mufa miniusb

Poate ca nu are legatura strict cu problema ta dar ...

 

Am citit ca pot fi probleme cu CH340 (din cauza la drivere software).

Am si eu un set de drivere CNC + Arduino (GRBL) si dupa ce am studiat mai mult am ales sa folosesc un Arduino Uno dar varianta care se foloseste de un AtMega16 ca si convertor USB-serial, iar la acesta am schimbat firmware-ul cu un firmware modificat pentru a elimina probleme.

USB to Serial transmission errors

• It has been found that both genuine Arduino boards, and clone Arduino boards experience occasional errors in transmission of data from the host computer to Grbl. The related errors could result in unwanted motion of the machine. The problem was originally discovered on a an Arduino clone that used a CH340G USB to serial chip, but the problem is also present to a lesser degree on genuine Arduino's and clones that use the Atmel 16U2 chip. There is no fix for the CH340G USB to serial chip. An updated firmware is required to eliminate the problem on the boards using the 16U2 chip.

• Clone Arduino boards using the CH340G USB to Serial chip experience occasional transmission errors and their use is at your own risk. There is no current fix for this problem on CH340G equipped boards.

• Genuine Arduino boards and clone Arduino boards using the Atmel 16U2 USB to Serial chip also experience occasional transmission errors and it is recommended that users re-flash the 16U2 chip with updated firmware. You can use the instructions here: https://www.arduino.cc/en/Hacking/DFUProgramming8U2 to falsh the new firmware, and the new firmware can be found here:https://github.com/AlexHolden/Arduino/tree/master/hardware/arduino/avr/firmwares/atmegaxxu2/arduino-usbserial Many thanks to user AlexHolden for taking the time to edit the firmware to solve this problem.
