So, my buddy Mike mentions to me in conversation, that a CNC mill would “sure be a fun, yet daunting project to undertake!” He mentioned this to me after I said, I need a mill to route PCBs for projects.
Build my own? I had never even thought it possible. After a bit of research — and research for me is in the hours to days category, not minutes — I made up my mind to start building one.
Well, now that I have a blog that is partially working, I’m going to start posting the info on here. Perhaps, it will be help to some and humorous to others. I tell you, I’ve learned a lot over the last few months and have already made up my mind to build a second generation machine, since this prototype has actually “kind of” worked. Yes, there are still a lot of bugs to discover and correct, which will be addressed in subsequent posts.
I had no plans when building this machine, and just decided to measure and build on the fly. That’s how I learn and how I roll. So, without knowing anything about steppers, how much power they need, the proper drivers, g-forces of the gantry, inertia, zed-axis height, how much of my money Mike had actually spent without me knowing, etc. I set in.
To begin, why not start with the base. Any good builder knows a building is only as good as its foundation. I set out to build the base. It’s a simple, heavy-duty base made out of old sectional-desk parts. People will scoff at the use of particle board, but guess what, this stuff is tough — far tougher than the MDF crap from the box-stores.
So, here’s the base:
