Now that I think about it, that's true, there is no hardware flow control for RepRap firmware. Sorry, forgot about that. Every command is responded to with "ok" if it's been accepted into the buffer. If there's no room, the "ok" is delayed until the buffer has space. So maybe "copy file com1:" might not work well, but a very simple expect script could do the job.

Some firmware lets you use the nonstandard 250000 baud rate. On Linux, 250000 is supported by newer kernels but requires some libraries be updated (pyserial for Pronterface and Octoprint). The reason that's chosen is because it divides down with no clock error to the CPU clocks used on some of the AVRs used for RepRaps.

This isn't a problem if you use 115200.

Is that what you were thinking of?

You can throw any bitmap at any color laser printer, and it should print it.

Take any 3D model and send it to a 3D printer and you'll likely get a blob of goo if the toolchain doesn't choke on the model first.

Mapping a 2D image to a 2D surface is easy. Taking an arbitrary mesh and turning it into instructions to manufacture a mechanically sound object is hard.

The bogosity meter just pegged.
