Offline G-Sender

[harinderbhinder]

I found this repo for offline grbl controller
https://github.com/LEKN-TECH/G-Sender

I'm using grblhal on custom board using stm32f401
Right now i'm using motors(XYZ) and limit switchs
what pins i can use to connect arduino(Tx, Rx) with stm32f401
so i can run machine offline

It depends on your map file - these are the pins currently supported (up to 3 ports can be defined). An example.

If the offline controller is of the "man-in-the-middle" type you will have to switch to UART comms instead of USB, if not enable MPG mode and use a switch for the switchover signal - or modify the the offline controller to send the switchover command character.

@terjeio can you please help me to fix
i'm using STM32F401CCU6

[env:blackpill_f401cc_uni]
board = blackpill_f401cc
board_build.ldscript = STM32F401CCUX_FLASH.ld
build_flags = ${common.build_flags}

See Inc/my_machine.h for options

-D BOARD_STM32F401_UNI=
-D USB_SERIAL_CDC=1
-D SERIAL_PORT=1
lib_deps = ${common.lib_deps}
lib_extra_dirs = ${common.lib_extra_dirs}

nothing changed in my_machine.h
nothing changed in stm32f401_uni_map.h

if i enable MPG_ENABLE=1 then its asking for mpg mode pin
but i updated my offline controller code to send : 0x8B
void setup() {
lcd.init();
lcd.backlight();
lcd.begin(16, 2);
pinMode(upPin, INPUT_PULLUP);
pinMode(downPin, INPUT_PULLUP);
pinMode(selectPin, INPUT_PULLUP);
pinMode(cancelPin, INPUT_PULLUP);
Serial.begin(115200);
if (!SD.begin(SD_card_Reader)) {
lcd.setCursor(0, 0);
lcd.print(F("Card Error!"));
while (1);
}
Serial.write(0x8B); // Enter MPG mode
delay(100);
lcd.clear();
lcd.setCursor(0, 0); lcd.print(F(" Harinder"));
delay(2000);
sendCodeLine("$10=0");
showMainMenu();
}

See the description in my_machine.h, you will want MPG_ENABLE=2 to use the toggle command..

@dresco @terjeio now my offline line is connected using
-D SERIAL_PORT=1
-D MPG_ENABLE=2
I added this code : Serial.write(0x8B);

its moving motor but after sometime
can you please check my offline controller code

if i move x+ its moving but if again click on x+ then its not moving
means its moving only once for same command

[terjeio]

can you please check my offline controller code

I may do later - I have to clear my inbox first.

Can i run file from offline controller using MPG mode?

Yes. Details here for how to switch.
