how do you do angled cuts? By stepping the depth on every pass, or just cutting it later on a tabelsaw?
Best regards,
Teun.

Thanks, always good to follow this thread, haha.
I'll keep you updated.

Making angled cut's on the cnc does work, but it's a time consuming process.
Right now my X-axis isn't very fast, only 3m/min.
For making angled cut's a bit more speed would be nice, I'm working on it.

At a cutting speed of 2m/min, the cutting of the flightcase took about 45 minutes.
If I had done all the speaker panels in one run it would have taken about 95 minutes to cut everything, except the angles.

For these speaker panels I used a Festool plunge saw to cut the angles.

I'm planning on buying some different sizes of v-bit's to cut angles.

Made and spray painted the doghouse for the mixer case:

Also spray painted the 12'' speakers:

Letters came out nice:

I thought I would post this here..
First CNC moves.The z axis is temporarily made from wood in order to cut an alluminum one when the CNC is ready.The small dremel is also for testing purposes till the Kress spindle arrives.
Built for small to medium sized speakers and alluminium parts.
These are the first motor and tuning tests.Sorry for the bad photos..

Decent size, you can still build some boxes with that.

 

At the moment, my own cnc is not yet finished, but I have started on another one.

Not for myself, for in a workshop.

 

This one is made out of 18mm birch ply.

5m wide, almost 2,5m high.

 

Rack and pinion for X and Y, Z had a 16mm ballscrew with a pitch of 10mm.

Nema 34 11,2Nm motors are used.

 

A few pictures, 

Construction of the frame:

 

 

 

The machine in its final position. The spoil board will be replaced by mdf or birch plywood:

 

 

1.5Kw spindle with auto tool changer:

That looks ace Djyves!!

Is the frame fixed to the floor and wall?

Are you running direct drive on the X or is there some reduction?  Im considering gearing mine as im missing steps, i need to eliminate a few other things first though.

Where did you get the tool changer?

Frame is fixed to the wall.

I'm goint to try direct drive this saturday, if it doesn't work out I'll try some reduction.

What sort of motors do you use?

The tool changer comes from some russian webshop, I'll look it up.

Cheers yeah id be interested in a tool changer that didnt cost loads.  Im only using 3.1Nm steppers with 1/8th micro stepping.  So i think you should be fine for torque.  Ive been having issues with the pinion slipping, i just tightened them up again (and snapped the head of a M3 cap head screw) so hopefully it will be ok now.  I dont know if its an issue due to backlash or stiction from running direct, there dosent seem to be many people doing it, plenty are doing it with geared steppers though.

Heres a little vid of my machine i made to for the guy at cnc4you to see what he recons on my motor tuning.  https://www.facebook.com/video.php?v=10152969974815229&pnref=story
