Anybody? I've started drafting my first CNC mill, looking for people that have built one already to share experiences with.

Cheers,

Sander.

I think your post is better placed in the crafting topic.

Not to be a pain, but if you want to use it for anything but drilling PCB's, you will end up with a cheaper AND better machine, by simply buying a used one.

I have been taking part in such projects in the past, and no matter what you do, you end up paying too much for the end result......even with my connections and possibilities in that field.

As it is now you can have a respectable used CNC mill for ligther projects for around 10.000 USD. For that price you will find it hard to even buy the main parts that are real DIY hostile.

Sorry :cry:

No, no, not so, it is just for PCBs, woodworking, aluminium etc. not steel or iron, I have a friend who built one and that's working just great.

If you don't need higher precision, I'd say you should just copy your friends design. It looks like reasonably cheap and readily available parts.

Yeah, I'm not aspiring to reach precision greater than 0.01-mm which is easily attainable with his design. However it is always nice to share ideas etc.

Cheers,

Sander.

I have once made a reasonably ok CNC mill. If you are interested in stuff like rigid tapping and the like I can give you a few pointers

And with some help from a 'mechaniker' from Germany I was able to complete my CNC mill in record time to my exacting specificaties, see below images for an impression. Usuable area is ~800x500x100-mm. Now there's no speaker cabinet I'm afraid of building, nor do I need to worry any longer about cutting square holes in amplifier cases and what not, heck I can even engrave a text while I'm at it, so I'd say bring it on!

Got any assembly instructions? I'm on my way to Radio Shack to pick up the necessary parts...

Nice :cool2:

Have you gotten around to testing it yet ?

Sander,

What are you using (hardware and software) to control your CNC setup?

Thanks,
Bryan

I've been using the free software EMC (Enhanced Machine Controller) from http://www.linuxcnc.org for a couple of years now. It's very stable when properly set up. The new version works fine with Ubuntu Linux, which even (IMHO) makes it somewhat user friendly.

If you use steppers with EMC then you only need a simple I/F card with step/dir inputs for each channel, generated by EMC on the standard parallell port. For lower voltages single-chip solutions like A3955 or LMD18245 works fine, for higher currents and/or voltages special drivers are needed; I bought mine at http://www.damencnc.nl which has 80V/7A spec'ed stepper drivers.

I haven't tried closed-loop or servos, but given the right hardware EMC has no problem supporting it, it even does hexapods.

The CAM part OTOH is a totally different bag, I recommend learning G-code since the commercial packages are incredibly expensive. There is a free software add-on to EAGLE PCB that does isolation milling.

Just my $.02 worth.
