This proyect is actually the final proyect of my studies. Wasnt intended to be here, and i wanted to present another proyect, but seing i dont have time to present 2 proyects at the same time, i thought... what can be the worst that can happen? So... here it is
The idea is to control a V-plotter with the esp12e, a board with the esp8266 in his heart. There already exists a prototipe. I will upload some photos tomorrow, and i guess i will start digging code at some point this week or the next. If this proyects goes to Internet of usefull things... maybe? Probably not, but hey....
I am not used to write my progress, but i will try my best.
The kicad files. There are at least 3 or 4 versions of the board. I dont think u should use any of these for making them in a pcb House. They are prototipes, and have one pin in the 74HC595 WRONG. I will end making a real FINAL VERSION

NodeMcu code. Needs Acrobotic ssd1306 library (will change in the future, i used it for tests), WiFiManager library (great library, maybe i will change somethings), and the usual esp8266 and C libraries
Well it has been a long time ago since the first and last post... I usually dont document my progress over something (even if it is a great idea, i know). I jst write my thoughts on a sheet of paper, and try to put them in practice. The thing is... i already ended my degree and got a 9 in this proyect, which is quite nice... But it is still far from finished
At the begining the idea was to make a vertical plotter that could connect via WiFi, using Telnet (in this case, but there is a good reason for that: Pronterface can use Telnet) or another comunication protocol. But after building the board, and programing it for a vertical plotter i realised... it could just work for any plotter anyone wants...
The idea of conecting the esp8266 (ESP12E, in my case) with a 74HC595 to the servo and to the Polulu stepper Motor drivers came from here (hackaday). Someone had the idea to make a 3dprinter with a esp8266. I dont know why they stoped doing it... They had proveed that it could be done....
Anyway. This proyect has becomed INTERNET OF PLOTTERS. Still a silly idea. But i cant see anyone anywhere trying to do it.
I will upload the arduino for the esp12e (nodemcu code) and the kicad files, here to hackaday... I have to say... it works. But it has too many flaws (for example: diagonal movements are not calculated right(still dont know why)). I stoped working a month ago in the proyect (I have a lot of things to do), but i will continue. Everything is explained inside... for anyone that wants to give it a shot. But it is in spanish (sorry..., when it is ended and i have tested it, i will put everything in github, in english)
