DIY Printer P6: A servo joins the party!

Time for some real progress this time! The sixth part in this series where I make a super-basic printer with an Arduino.

It’s pretty much ready to print – just a little hot glue and a sheet of paper and it’s all set! But unfortunately, this video is already ~8 minutes long, so that’ll have to wait.

After trying out solenoids and ruling out floppy drive motors because of speed, I looked at servos as a way of moving the pen up and down. I settled on Hitec’s second-fastest micro servo, which is digital (means it’s not limited to 50 Hz update intervals) and has metal gears (means it won’t destroy itself quickly). It’s designed for use in R/C helicopters, so I’m hoping this will handle the fast motions over a small range of travel, with a light load, well. I’m certainly impressed by it so far.
