| project on thingverse that seems compatible.

| printer. I think of printers as working on pixels (maybe I'm
| wrong about this) while drawing machines and 3D printers have
| lines as their primitives, right? Maybe 3D printers could
| become drawing machine, haha. 3D to 2D drawing machine project:
| project on a plane.

| I've seen wall-sized vertical ones that work with a
| microcontroller, some threads and a few servers.

| drag a pencil or pen across a surface. It is a physical act. It
| is active pursuit, emphasis on pursuit. You chase, seek, and
| pursue the final drawing

| The more-common term for a "drawing machine" is a "plotter", no?
|
| (I guess you wouldn't normally call a non-automated "drawing
| machine" a plotter -- but why is that?)

| That's one of them, as mentioned on the site. ;)

| Plotter is a drawing machine connected to a computer

| Pantographs are used in woodworking too! Put a router in place of
| a pen and have the stylus trace a jig and you're cutting
| accurate, repeatable tenons! Here's an example

|
| They're also used horizontally to trace letters/drawings into
| wood as in the traditional use of the pantograph

| massive (5cm?) steel.

| Well that ended up being a hour long rat hole. So many awesome

| Really neat site. Would love to see the pages for each machine

| plans to make such a device yourself.

| Sharing a drawing machine I designed and wrote about a few years

| digital conic projection perspectives inspired by Piero Della
| Francesca's "Other Method," which is essentially a 15th century
| drawing algorithm for sampling a point cloud and representing it
| in 2D perspective. I can convert this into a blog post if people
| are interested. Unfortunately my professor kept the actual
| machine for their "collection"...

| Fascinating stuff. Thanks.

| I teach drawing from observation. I start off with talking about

| straight edge of a pencil. The trick is to identify points in the
| scene (intersections, corners, features etc) which corespond to
| each other on a vertical or horizontal axis. with a few of those
| done, the whole drawing drops into place.
|
| Edit. Unless I am missing something, I see no mention of Van
| Goghs sighting grid. Crude, but effective.
