Basically in the Arduino software i selected the wrong board so it was connecting, the correct board for the seeeduino is Arduino Duemilanove w/ ATmega 328.

After sorting this out, everything has worked fine, the beast is alive!

Just need to sort out a slicker lasercut gondola to get the accuracy of the pen up. I also may need to order some spare sprockets (I’ll email you about this at some point no doubt)

One more thing, thanks for updating the instructables, its helped a lot!

The forum is a better place to look for a hand, but first of all, have you managed to get the polargraph_server code uploaded to the arduino? That’s the polargraph_server_a1.ino code file you can get from http://polargraph.googlecode.com/svn/embedded/trunk/polargraph_server_a1.ino.

Follow the instructions at http://www.instructables.com/id/Polargraph-Drawing-Machine/step8/Electronics-Arduino/ if not. If so, then that’s more of a puzzle, because to upload it, you need to have your serial port working, and if that’s working, then you should be able to watch it with the port monitor. I would get it working, and broadcasting “READY” in the arduino environment first before worrying about getting the controller to connect to it.

Cheers!

This is Bob from Instructables. I was the guy posting all the questions over there. I just wanted to let you know I tried out this version and I can open images OK now. Thank you.

I’m still waiting on my stepper motors and other stuff, so it will be some time before I can actually test it all out for real. Thanks for everything! Can’t wait to start getting some drawings done 🙂

thanks for sending me those parts in the post! I’m almost there I think ( I hope!)

I’m having a few issues with the software at the moment, Everything seemed to be running smoothly, but on the Polargraph controller (_zoom) it says “polargraph not connected.”

I believe I have all the folders and elements in the right places in arduino, but when i click serial monitor no information comes up. Would you know why this is?

I’m afraid I’m not the greatest with coding etc but have scoured the internet for answers and had no luck (im not really sure what im looking for!) so any help would be really appreciated.

all the best,

Rory

PS. Sharpie Skull 895- is seriously awesome, I need to get drawing!

The vector drawing is just incredible, I did the most imposibly complicated image today, took just over 12 hours to complete and it was only A3,came out absolutely perfect, not a line out of place.
