little bit about me and how I got hooked on CNC.
Here is a link to the Slides I used for a talk about my CNC machine, given at the Fair Use Building and Research Labs (FUBAR Labs) on 2/9/14.
CNC Router Build
I built a 24" x 36" cnc router using plans
by CNC Router
There are several steps to the build.
I got here and why 24" x 36"
I made some changes to the design.
Things that were forgotten, or didn't quite work out as planned.
Machining the Parts:
I'm on a tight budget so I didn't buy everything.
and Tapping: The 80/20 components and the CRS rails needed
some fabrication work.
Building a Table/Enclosure:
I needed a table to put it on. May also want to enclose the router.
Assembling the Router:
Without a step-by-step, it's not as
easy as it looks.Packaging the
Electronics: I've put my driver, power supply,
fans into a recycled computer chassis
Things not covered above. The mount for the router, work surface, dust collection (new), limit and Estop
Checking Alignment: Making sure the parts come out square. Checking the work surface for flatness. (new)
The Bottom Line:
I've tallied up the cost of building the
router 'my way'.
Diagnostics: How do
you really know it's working ? I built a pen holder and wrote a
First Cut: Diagnostics continue - cutting known shapes to check results.
What Speed: How do you set max velocity and acceleration? How do you know if you lose steps?
Software: The tools I've
used to make parts so far.
EMC2: Here's my EMC2 setup and some customizations I've made to the Axis screen.
Useful reference items
Vacuum Hold Down
You can make your own. It's a cheap alternative to using Styrofoam or
MDF for test cuts. It can be used to make models for casting.
