Arduino Nano Problems

Using Arduino Programming Questions
1

Using NANO with W7 64bit system.
Wrote CNC program using examples. Compiles OK and uploads OK. Then I wanted to check HW using G-Code Sender. This does not work. GCS is version 2.0 Error message is GBRL not finished loading All day same message. I used high 115200 Baud rate and tried 9600 baud rate. (Yes I am New as well.) Ijust want the program to work. I tried Java and the bat file for GCS to no avail. Audrino Nano is up and running.

I need help

You have to provide a huge amount of more detail if we are to be able to help.

If this is a CNC program that you created yourself from scratch as an alternative to GRBL then I wonder if you have included whatever GCS expects to receive when it communicates with GRBL?

Additional Information was requested. GCS was used also before uploading my program to the Nano, but it still did not work. I am wondering if I need to dump all programs from the Nano first? What program do I use to do this or must the CNC program be loaded as well. What other information is needed ? I will try anything.

Thank Robin for your information. Still having problems but I need general help with this forum.

How do I go to just my messages without having to go thru my personal update stuff. Just to note, I am a 100% Disabled Veteran (now at an ancient age).

You have not provided any additional information. You seem just to be asking more questions.

For example I asked what program you have uploaded to the nano - is it a CNC program you wrote yourself?

When you upload any Arduino program it automatically overwrites any previous program.

When you ask "What program do I use to do this" I don't know what you mean by "this".

When you ask "must the CNC program be loaded as well" you don't say what program is already on your nano (or what CNC program you are talking about).

Maybe it's time to go back to basics. Why are you not using GRBL?

Robin,

Thank you for your reply,

  1. Arduino NANO
  2. I just switched to the https://github.com/MakerBlock/TinyCNC-Sketch
  3. Compiled it (OK)
  4. Uploaded OK
  5. Nothing runs.
  6. wanted to use an image. Did not work. Someone said to use the "G-Code Sender" SW
  7. Does not work no matter which version. Error message says "Grbl has not finished booting"
  8. What am I doing wrong and where do i go from here?

Your github link does not work!

Here is the Github link: GitHub - MakerBlock/TinyCNC-Sketches: Arduino sketches for the Tiny 3-Axis CNC and drawing robot

Your Github link lists several programs. Is it correct to assume you are using the program called TinyCNC_Gcode.ino ?

There seems to be absolutely no documentation for the project - which is the best reason I can think of to steer clear of it.

Because there is no documentation I am only guessing about the following ...

I suspect the program is not designed to work with GCodesender. There seems to be a Processing program in the Github link for sending data to the Arduino.
