gcode interpreter esp8266

I modified https://github.com/alx/reprap-arduino-firmware/tree/master/GCode_Interpreter arduino gcode interpreter for working with esp8266.
Can command only 2 motors byj-48 unipolar on D0-D3 and D5-D8.
I find and i resolve some bugs ... you can see in source file.
Program is compiled with arduino ide with settings:

//Arduino flash:DIO Flash size:16M Reset method:Nodemcu Upload speed:921600 Erase Flash:All flash contents


I disactivate termocouple support and axe Z ... but easy can be activated ... if find some pins free if use 74hc595 ,74hc164d ,ecc



Actually program work only with serial port with 250000 bauds.
You can use gcodesender from chrome https://chrome.google.com/webstore/detail/gcode-sender/ngncibnakmabjlfpadjagnbdjbhoelom?hl=en
and this gcode file to test firmware https://sites.google.com/site/esp12wifi/3d/test.nc

If you not want modify and compile the code or not have or not want install arduino ide ... you can use https://www.espressif.com/sites/defa
