I've attached a schematic that I thought I attached yesterday.

I figured this out! What I was doing wrong was the following:
When I re-flashed the device for nodeMCU I used an executable modemcu firmware programmer. It seemed to have the binary file included? Perhaps I setup this incorrectly.
So, I used a different application.ESP8266 Flash Downloader. I had to download the binary file:
https://github.com/nodemcu/nodemcu-firm ... latest.bin
After I re-flashed I pulled the GPIO Pin out of ground and reset the ESP.
I then used ESplorer to Upload my LAU script. This time it went past 22% and all is good.
Let me know if anyone needs help on this.
A guy on Youtube did a great video on the nodemcu flashing:

I have my circuit on a 2x8cm through hole prototyping board which includes the USB type A male header for power, and a 5v to 3.3v reducer. Also headers for the UART board to put into and a breakout header to go to my prototyping board which takes out all the ESP-01 external pins. As I said previously, I've also got a 220 uF capacitor between VCC and GND.
But glad to hear that you've got it all working fine.

Please see my Developer FAQ for Q&A on nodeMCU Lua before asking a question here that's already been answered. This and the other official documentation should be your first reference for developing Lua Apps

After playing about with direct AT commands I've opted to flash the ESP8266 module with lua. Downloaded the ESP8266 flasher.exe, clicked on flash and away it went until it closed the com port. Following a tutorial page I downloaded the ESPlorer v0.1 build 206 (http://esp8266.ru/esplorer/). I cut and pasted the sample code that allows you to control a lED or two from a web page into the GUI and opened the com port. Having named it as init and clicked on the save to ESP it trundled away, noth the blue LED on the ESP device and the TX/RX lights on the FTDI adapter flashing away until the window in the applicatuions stated DONE. Duration 7785ms - com port closed - Success.
I closed the port and opened up a terminal window (I use Termite). However when I restart the ESP device (with or without the GND link for GPIO in place) the open I get
I've reflashed the device and tried sending the Init code - each time the same results - What am I doing wrong. Obvioulsly Lua is installed as I get that message stating the build etc... but why is it that the program won't run ?
