gcode interpreter esp8266

thingiverse

I modified the GCode Interpreter from https://github.com/alx/reprap-arduino-firmware/tree/master/GCode_Interpreter to work with ESP8266. The Arduino Gcode interpreter now supports only 2 motors on pins D0-D3 and D5-D8 for Byj-48 unipolar steppers. After investigating and fixing some bugs, you can view the source file for further details. I compiled the program using the Arduino IDE with settings: //Arduino flash: DIO Flash size:16M Reset method:Nodemcu Upload speed:921600 Erase Flash:All flash contents I disabled thermocouple support and Z-axis, but it's easy to re-activate by utilizing free pins with 74HC595, 74HC164D, or ECC chips. Currently, the program only works on a serial port at 250000 bauds. You can use GCodeSender from Chrome at https://chrome.google.com/webstore/detail/gcode-sender/ngncibnakmabjlfpadjagnbdjbhoelom?hl=en and test with this gcode file: https://sites.google.com/site/esp12wifi/3d/test.nc. If you don't want to modify or compile the code, or don't have Arduino IDE installed, you can use the Flash Download Tools from Espressif at https://www.espressif.com/sites/default/files/tools/flash_download_tools_v3.6.4_0.rar to upload Gcode_interpreter.bin from the zip file included here. You can also find a flasher tool on the Espressif website at https://www.espressif.com/en/support/download/other-tools, and follow the images to set up the flashing tool. I recommend erasing memory first before flashing. I'm using this Gcode Interpreter for my low-cost foam cutter CNC Costycnc. Currently, I use a modified Arduino Grbl 0.8c for working with 28Byj-48 unipolar steppers at http://www.costycnc.it and https://www.facebook.com/costelcnc/.
