I think of setups that use a belt anchored at the ends of a linear guide and wrapped around a motor pulley near the center as a variation on rack-and-pinion drive. Using a belt with a couple of idlers to allow the belt to wrap 180 degrees around the pulley fixes some of the inherent problems with a real rack-and-pinion drive. This is a discussion worth including, that would require some backgrounds on rack-and-pinion drives. Not sure they warrant their own chapter, but you could discuss them in that context elsewhere if you decided they don't.On May 14, 2019 at 07:11:42, RanchRifle (mdd...@gmail.com) wrote:
I dunno, rack an pinion may not make much sense for typical desktop printers, but if you are looking for large scale stuff....--Of course things like BAAM and the various concrete printers are probably a bit out of the scope of this series. ;)

I told my wife the history and she laughed and said good luck trying.
I think your target audience knows your books are about engineering. People get offended very easily and it's really hard to eliminate every possible offensive word or phrase. I wouldn't worry unless people make a big deal about it.
Put all that work into making a nice illustration but couldn't get the flat part of the circle in the right orientation?!The very small print light grey label / attribution text is also annoying.All I really wanted was a photo of a flattened circle on a print, but I'll be darned if I can find a permissive license photo of one anywhere. Might have to queue up my R2x with some loosened belts, which is just a hassle.
