    Hi,Thanks for the information.Yea, it sounds like it failed to connect to WiFI.I assume when you view the USB terminal output on boot up it says it failed to connect to WIFi?After pressing the button for more that 2 seconds were you able to connect to "Tracey WiFi Config" with a device and open the web page in Step7 ?

    Hi Eirwin,So I assume you got Tracey connected to the Wifi and the blue light is on?I assume that the phone or tablet running the Tracey app is connected to the same WiFi network as the Tracey device?

    Hi,the IP address is correct all right.Are you connected to the Wifi access point called "Tracey WiFi Config" on your laptop?

    Hi ErwinM5,Its explained in Step 7: Testing the Controller Board - Connecting to WiFIBasically after pressing the button for more than 2 seconds, you should see an access point called: "Tracey WiFi Config" on the list of WiFi devices.Connect to the access point and open a browser with URL: 192.168.4.1Than means -in the web browser -instead of putting a web address like www.google.com you enter: 192.168.4.1 Then you should see the web page in the picture in step 7.Let me know how you get on or what specific point you are stuck. Regards,

    Hi,I'm not sure exactly your are asking.The draw area is correct but where the assembly is placed is not, the right edge of the servo should be roughly at the edge of the draw area.The movement range of the servos is not correct, they should both be another 45 degrees anti-clockwise.Are you having trouble with the calibration process? You don't need to know all this stuff, you can just follow the calibration process in the instructable, its not too hard and you don't have to worry about these angles and stuff.Let me know if you need any more help.Regards.

    Hi ErwinM5,Yes you are correct in your pin assignments. It is confusing all right, I had to look up the Feather pin out's the the mapping is not obvious at all, I will add a step for this.Below are the pin out for the Feather:Top Servo: IO16Bottom Servo: IO0Lift Servo: IO12Button: IO14LED: IO13You might want to consider a different broad than the Feather if you are going to be designing a PCB; from what I can see it wont supply 5V and you will need an external supply.With the other types of ESP8266 break out boards, they can supply the servos and you can use a power bank etc.Anyway, hope this helps and good luck.

    Hi ErwinM5,It looks great, well done!Really looking forward to the drawings once you have your electronics.Let me know if you get stuck on anything or need help.

    Hi ErwinM5,I believe the Feather would work OK but there are cheaper options:https://www.amazon.co.uk/Klinkamz-D1-MINI-ESP8266-...https://www.amazon.co.uk/IZOKEE-Internet-Development-Wireless-Compatible/dp/B01N4OYOKD/ref=sr_1_20?keywords=ESP8266&qid=1564738129&s=gateway&sr=8-20Both of the above have built in USB for programming.

    Hello,and thank you for the kind feedback.Regarding your question about the Nano code and Bluetooth; I don't think there is any code available I'm afraid.Some issues I would see are:The Nano might be a bit slow at doing the needed calculations for translating the X,Y positions to servo angles.The Nano only has one serial port so I guess you would have to use software serial for the Bluetooth module and that would be more over-head.The Nano may not have enough RAM for the calculations needed - especially if you wanted to include the GRBL interface and Gcode interpreter. I do plan on releasing Arduino code that demonstrates converting an X,Y position to servo angles in the near future, perhaps you could experiment with that if you are experienced enough with Arduino coding..Anyway, thanks...

    Hello again Sembot,I just wanted to add; I seen you comments over on Cute Drawing Buddy, you have built a very nice drawing machine there -I assume based on Barton Dring's clone?Tracey will work with that assembly no problem, in fact it was the first build I used.Get a ESP8266 and you will have it going in less than an hour.Best of luck.

    It's a cool project. Do you think a Sine wave would be doable?
