So I have a 3018 Pro running GRBL 1.1, the USB connection is fine but I need to put this in the garage so need WiFi working.
I was planning on using LaserGRBL and adding the usual ESP8266 in “websocket” configuration (it can supposedly do that or I guess telnet with alternate hardware).
I went to LaserGRBL’s webpage and he gives a file “websocket.ino” which I guess is some kind of Arduino development file, I don’t do Arduino so don’t know.So I went looking around on GitHub and there’s an entity Nodemcu that has entire libraries of ESP8266 code, in fact they have it set up so you can select from up to 70 different modules, plus they have a nice binary file flash loader.
The problem is I don’t really know which modules GRBL 1.1 actually needs to have on the ESP8266 in order to make websocket functionality work.I tried “guessing” but I wasn’t getting anywhere (I can activate the hardware and see a signal from it but I can’t communicate with it).
Nodemcu hasn’t responded to my email yet, ESP8266.com hasn’t either and LaserGRBL simply REFUSES to provide support in any form!Can you point me in a direction where I can make progress?
I don’t know the architecture of GRBL, LaserGRBL OR websocket, and for it to be up to me to “reverse engineer” ALL of this source code JUST to complete the codebase for something that has already been thoroughly integrated and debugged just doesn’t seem reasonable or logical!
Thank you in advance.

Hi Jeff,
you must say what board do you have in your 3018, and you must know if It’s Arduino based or completely integrated.
When you identify the RX and TX pins you must follow this tutorial.
Bye Renzo -
Yes it’s Arduino-based.
Nobody showed me a detailed way to identify the board.
If it helps the “brand” is something referred to as CNCTOPBAOS and the machine is called 3018 PRO MAX.Yes I know about RX and TX being swapped between Arduino and ESP8266, and the ESP8266 running off 3.3 volts, I have that aspect “all under control”.
Another part that may help identify is the offline controller connector is 8 pins not 6, and it ships with “Candle” but I need the other program so I can use WiFi.
Is there some master reference where I could look up more of this myself?
I realize this isn’t “development” therefore not that interesting to you but my lodging conditions don’t allow me to run either the computer out there nor the CNC in here!Thank you Renzi.

OK Renzo (sorry I apparently spelled your name incorrectly, it was VERY late)…anyway it’s possible maybe you’re familiar with this code right?
(If I’m going to get someone to help me I want to try and ask for help with something they’re familiar with) So somehow it finally occurred to me what this guy LaserGRBL wanted me to do as he described on his websiteto get the websocket sketch built, and I did my darnedest to follow his instructions to the letter, but then I came up with these errors:

exit status 1
‘WStype_t’ has not been declaredMaybe you have some idea if I could still be doing something wrong? Or would you have a recommended fix? All I know is he says he’s not providing support, and I guess that’s fine but I would think if he takes that position the code ought to at least compile cleanly, so now what do I do?
