Wireless stepper control
thingiverse
Migrated existing code from Dan Royer so users can now make their things wireless. Sample usage at https://youtu.be/Ii7Cn1PlVFY and with two axes at https://youtu.be/OLvL4guifRU. What you see below the CNC shield is not an Arduino UNO but a Wemos D1 board at http://www.prometec.net/wemos-d1-esp8266-wifi/. The plan is to use this to replace the Arduino UNO in my 4xiDraw at http://www.thingiverse.com/thing:1444216. Code includes a trapezoidal speed profile like GRBL. Users connect to it using password "0123456789" which can be changed in the source and using netcat -u 192.168.4.1 9999. SSID and password can be adapted to fit your wifi network, then figure out the IP address obtained by the board. Servo control has been added, use M3S(microseconds) command to set that pulse width for servo output on pin (pulse Z) D14. A sample capture of the output is provided in case you want to see the timing details of the thing. More up-to-date code can be found here: https://github.com/misan/ESP-stepper-servo/.
