GCODE it's a machine language that's a series of instructions coded to make the machine do certain orders. As far as we know, it's commonly used by 3Dprinters and CNCs
You can perform individual movements via terminal or the cnc.js allows you to upload a bulk of GCODE files. (that's a plain text file)
Those movements are better explained in the link but in this case we have to set some commands to make sure that everything goes smooth.
As I commented before, there is a servo motor with a plate. You should be aware (using both cameras) of the state of the plate so you don't break anything.
So, the commands we had to use
This sets the machine to Absolut coordinates mode. (G91 it's to set relative coordinates from the point where the machine is) This is important because all the commands that says "go there" need a frame of reference.
This sets units as milimiters. Because we don't use imperial system here. M3tric 4ever.
M280 P 1 S 90
Remember that servo I've mentioned before? You better do, because this sets up the position of the plate so you can actually can touch the sand. Now, what exactly this command does it's to say hey, to the servo motor 1 to set into the position of 90 degrees. You have to make it before the next command.
This calibrates the home for x, y and z. This is important because maybe there are any kind of mismatch between where the machine think it is and where actually is. This reduces the error to thero. If you're on a hurry you can only set G28 X Y to skip the slowest part of the Z calibratiion.
Now we're set to go.
Wait. We have to TRANSLATE A DRAWING INTO GCODE. And we're recording this. HALP
### Setting a drawing into gcode.
Ok, that day I freaked out a bit just because my internet connection wasn't good enough so I had some problems. First we need a drawing. If you have one but you need to vectorize it you can check out the week2 because [I have some info for you!](http://fabacademy.org/2020/labs/barcelona/students/david-prieto/assignments/week03/#vectorizing-images
In my case I have already a drawing that I made in illustrator so it was _already_ vectorized. Yay.
This is the physical version:
