Fellow Shapeoko users,
There’s a famous quote that is supposedly attributed to Albert Einstein that goes “If you can’t explain it simply, you don’t understand it well enough”. I’m in the mood for testing that statement on myself, to check what I really learned (and understood correctly) about CNC in general and the Shapeoko in particular in the last 2 years.
I fancy writing an e-book that could guide a new user from unboxing the Shapeoko kit to mastering the theory and practice of its most common uses.
Don’t get me wrong, I absolutely appreciate the huge amount of effort that was put in the Shapeoko wiki, and the treasure trove of information that this forum is. But I’m oldschool and I think that an actual book with a beginning and an end can come in handy as a roadmap/support in parallel to navigating the gazillion links and youtube videos and forum posts out there. Most general CNC books I have seen are targeted to more rigid/pro machines, while hobby CNCs call for a different, humbler approach.
It would my own endeavor, and would be available for free once completed.
However, and this is the reason for this post:
- for it to be more than a superficial tutorial, it will take a significant effort.
- I would probably be unclear or plain wrong one some aspects, and would need someone more experienced to point it out.
- English is not my native language, so it would probably sound a little weird, if no one checks/fixes my English.
- I only own a standard SO3, so my understanding of problems/tricks specific to the XL and XXL (e.g. bed sagging in the middle) is very limited.
The table of contents would be something like this:
-

- Probes
- Z mods
- bed mods

-
Troubleshooting FAQ
- top 10 mistakes & issues
The idea would be to stay independant from any specific project, because there is probably a great Youtube video already for every possible project, but rather going behind the scenes and getting a good grasp of WHY and HOW.
Anything obvious missing from the TOC ?
If I were to actually do this (motivation is a strange thing that comes and goes), would anyone be interested in either contributing to some chapters, and/or help with proof-reading it when a draft is available? No deadline, just a background initiative that could mature over the next 6 months or so.
EDIT: the latest version of the ebook is available here:
Online version : https://shapeokoenthusiasts.gitbook.io/shapeoko-cnc-a-to-z/
PDF version : https://drive.google.com/file/d/1NMKZ5VHGA_6NmcA0ykqQv60WiPigrlTR/view?usp=sharing
I also re-generated the ePUB version, it’s not as good (it has a few remaining format issues in places), but might be of interest to someone:
Thanks
