Finally, after months of writing small sub systems, I can now fully print with ink.

It still has a whole heap of improvements left for now:

• I cannot upload code while moving (dependent on a few handshakes that are not in place yet) so I am limited to 1000 lines of inkjet per sweep. No jolly wrenchers for now :(
• There seems to be some off by one and odd even errors in both the Arduino side and the Python side. Also some ringing that I have a hard time placing where it comes from. Will play with the dials a bit once the code runs smoothly.
• The code still takes forever loading an image (though I do not care at this stage, might use something like pypy later)

• The head has a hard time properly starting, hence the missing lines (though it has been sitting drying out for over a month, it will be fine)

Next post should take less than a month this time.

(PS. Also think of the hilarious amount of effort I spent the last few months, essentially building a crappy 2D, black and white inkjet printer.)
