Post Vector notches when scribing code.

Sandy and others,

I finally have some time off this summer to experiment. I am working with a vector file that seems to have uploaded and is drawing fine. However, every second or so (when the new line of code is sent to the arduino), the pen stops, then continues drawing. This pause in the drawing process creates dots at those steps if using a felt tip marker or pen.

My question is, can I somehow export all of my vector image and machine specs from Controller to a txt file of some sort that I can then load directly to the Arduino on the flash card? I assume the flash card will eliminate this pause (and jerkiness) as it is drawing vectors.

Any comments would be appreciated! Thanks!

Yep, that's the point of the SD card slot! The new comms is faster, but the sd card is still the fastest.

What you should do is build your whole command queue in the controller, making sure that the first thing you put in it is a "set home" command, and all your vector move commands afterwards. So you'll have "C09,4497,4497,END" (or something like that) right at the top of your queue.

You don't even need to have the machine connected, but either way you should have the queue paused so that the commands don't get sent right away.

After your C09... will be the thousands of commands generated when you press "draw vector". Go onto the _Queue_ tab of the controller, and click "export queue", and save it onto your SD card, with a name that you will recognise. Remember the SD card can only do DOS 8.3 filenames, so a maximum of 8 characters long.

So save that queue, then eject the SD card, and put it into your polargraphSD, label side down. Restart the polargraphSD, and when it's back to the menu, first lock the motors using "MOTORS ON" on the touchscreen, and then select "DRAW FROM SD", and then scroll through the files on the SD card to find the queue you just saved, and just press "DRAW THIS FILE".

good luck!
