Thanks,

Just ordered some parts:
- Gas struts to keep the pinions on the rack with minimal backlash
- A few missing pieces of aluminum
- Emergency stop buttons
- Nema 34 motor with lower phase inductance
- Other breakout board
- Ball bearings to guide and support the cable chain

Right now I'm also looking for a spindle.
Auto tool change would be ideal, but quite expensive, 
Please let me know if you know an affordable auto tool changer.

If it is not going to be automatic tool changer, it is going to be a watercooled 24000rpm spindle.

To start with I'm going to use a higher voltage controller to increase the speed.

The 230V AC controller turned the motor faster, but not fast enough.
With a new motor I get 7.5meter/min on the X-axis.

So now the speeds are:
X-axis 7500 mm/min
Y-axis 25000mm/min (slightly less)
Z-axis 5000mm/min

Did some tests on the machine, one of then is the speakerplans logo.
Letters were milled with a 90° V-bit, cutout with a 6mm endmill.
In the video the feedrate is 2500mm/min.

See the video here:

The end result:

Looks good what software are you using?  2.5m/min is not a bad feedrate for plywood and 7.5m/min is fast enough for rapids surely?  Did you say you going to get a high frequency spindle so you can cut faster though?

Videos not working btw.

Haha, it was the easiest way to mount this router temporarily.
And a clamp to keep the on-switch pressed.

I can go faster with this router, but the cuts do not look as good if I do.

I'm using Mach3 to control the motors etc.
I've used V-carve fron Vectric to create the speakerplans logo, very easy cam software.

I've orderered a quite a powerful router/spindle.
A 4Kw 24000Rpm watercooled spindle, with a 3-Phase 380V frequency controller/vfd.

It will arrive in about seven days or so.

nice job there,

You should try aspire v4.5 from vectric.Vcarve is pefect for simple jobs like speaker panels but aspire worth taking a look as it can create very complicated toolpaths and it is quite easy to use.

I use rhino v5 for cad files and aspire for cad.When i get the chance i would like to take a look at rhinocam.
Also i wouldnt worry about speed as long as it does the job right.Speed race is not waht you wanna do there,plus your knifes last longer

Post some pics when you get the new spindle.

I've also got aspire installed, works very well.
I like the Vectric software, all very easy to work.

Rhino v5 looks very good, I will try that one.
I'll also give rhinocam a go.

+1 on the speed.
You don't have to mill it yourself, so why bother with a little bit extra speed and get in trouble, break knives, etc.
I'll see what speed works for me with the new router.

Pictures are coming.

DjYves! Fantastic projects here on your thread Clap Thumbs Up
Just 1 question which I believe may be interesting for other DIY enthusiasts. 
Do you have thought about publishing plans/tehnical/electronics part list and solution details of your CNC router project on one place (may be new thread - Speakerplans DIY CNC router project) If anyone here decide to go your way and build one for himself that may save a lot of effort or money or nerves as you have already solved most issues you encountered while developing/building your CNC table? Geek  


Signature is important. So I always write something in this dedicated field.
