Como voce solucionou ele?

Obrigado!



I have the same problem.

How did you solve it?

Thank you!]]> Renan_Popy RAMPS Electronics Thu, 24 Mar 2022 09:55:30 -0400 https://reprap.org/forum/read.php?219,867573,867587#msg-867587 https://reprap.org/forum/read.php?219,867573,867587#msg-867587
If so I have a vague recollection that they designed this board incorrectly..


From pins_MKS_GEN_L_V2.h and pins_RAMPS.h
#define E1_SERIAL_TX_PIN 20
#define E1_SERIAL_RX_PIN 21
#define X_SERIAL_TX_PIN 40
#define X_SERIAL_RX_PIN 63
#define Y_SERIAL_TX_PIN 59
#define Y_SERIAL_RX_PIN 64
#define Z_SERIAL_TX_PIN 42
#define Z_SERIAL_RX_PIN 65
#define E0_SERIAL_TX_PIN 44
#define E0_SERIAL_RX_PIN 66

But for software serial to work you have to use a "change interrupt" capable RX pins see [www.arduino.cc]
"only the following can be used for RX: 10, 11, 12, 13, 14, 15, 50, 51, 52, 53, A8 (62), A9 (63), A10 (64), A11 (65), A12 (66), A13 (67), A14 (68), A15 (69)."

If you check the RX pins above E1 is trying to use pin 21, which is not change interrupt capable.]]> Dust RAMPS Electronics Thu, 13 Feb 2020 18:42:44 -0500 https://reprap.org/forum/read.php?219,867573,867573#msg-867573 https://reprap.org/forum/read.php?219,867573,867573#msg-867573 Estou usando a placa MKS GEN 2.0 com drivers TMC2208 v2.0 e não consegui habilitar a segunda extrusora
