Like everyone, I like making things. I'm currently a computer programmer by trade, which I adore, but I like building physical things when I can. I like pottery and lino cutting and photography, and I love the seaside, and the smell of hot solder. I have a few years of formal design training and design a small range of 3D printed jewellery, and a couple of other products I'm behind.

    The error is nothing to worry about - just an old command that doesn't do anything any more.

    Well, like every arduino program, it runs setup() (https://github.com/euphy/polargraph_server_a1/blob... as soon as it boots.You could put your pre-set list of commands at the end of that procedure.Remember though that you need to calibrate the initial start position of the gondola before any movement will work though.This is usually done using the exec_setPosition() procedure (https://github.com/euphy/polargraph_server_a1/blob... but there's no reason why you can't just copy those commands into setup().Remember the coordinates system that the machine uses internally is distance from points A and B (left-hand spool and right-hand spool), and the units are motor steps.

    You'd need some way of building the set of instructions that would form the text (set of coordinates to move to, lift pen up, put pen down etc), and once you have those it'd be quite easy to sequence them.A series of changeLength(...) commands.

    Ok, "this point falls outside the machine" and "line not on the page skipping it".These both mean either:Machine is not set up (do this with "upload machine spec")orHome point is not set (do this with "set home")or both.Every time you change the machine size, or motor settings you must "upload machine spec".Every time you turn the machine on, you must "set home".When you say you "almost made all the adjustments", which ones did you _not_ make?Someone else's configuration file would have their machine size and their motor settings in - how would it be useful to you?
