Re: New cnc.

Save up enough to buy a little cnc milling machine, or convert a milling machine to cnc. That would be far superior for cutting aluminum. Otherwise you will need to buy a very solid CNC router, and expect to spend around $10k.

Re: 3 axis mill/software business Idea

The longer I'm working with CNC routers, the MORE controls I want in my 'box'. I want servo motors with glass encoders and high end servo controllers. I want limit switches. I want control software that is easily to customize and write macros for tool changes, measuring and storing tool offsets, har...

Re: What do you do while the CNC is running?

I start sanding parts while other parts are cutting. Building furniture, the CNC cutting is the fastest part of the job usually. While one piece is cutting I'm either jointing and planing and gluing up the next blanks, or sanding the last parts to come off. I try to time my cuts so that they take ab...

Re: Project you're proudest of ???

Maybe not my most proud, but the coolest one I've designed in the last year anyway.

Re: pizza oven mould

When we made a pizza oven we just cut foam as a solid model (not hollow inside) and packed clay around the foam to form the outside dome and door (the foam formed the inside shape, and we formed the outside freeform). Then we cut and removed the foam once the clay dried, and built a roaring fire ins...

Re: V Grove Fold joint

waw this looks great. two questions 1-on your final product you show recessed panel on each side, why you do not cut the middle part at the same time since you have tool changer cnc. 2-do you lay out all operations manually? is there any software you design box and software grove joints by generati...

Re: V Grove Fold joint

Here is an example in 1/2" LDF. Took about 3 sheets, so you won't see all the parts on this one sheet.

Re: V Grove Fold joint

I've done many folding mitres in MDF using a 91 degree V-bit. If I'm making a complete box, I just draw a line between each part and cut on the line. You need a pretty large bit to cut 3/4" MDF. The one I use has a 3/4" shank and is 1.5" diameter. I cut at 12000rpm and 200ipm in a single pass for th...

Re: Maloof style seat tutorial

The seat model is just a very generic shape and size, not really meant to fit any chair in particular. You can either resize it to fit your needs, or use the tutorial to create your own size of seat!

Re: Maloof style seat tutorial

Now you need to subtract a round over for the front edge. I draw some vectors as shown. seat 8.png Then do a two rail sweep, subtracting the sweep from the baked model. seat 9.png This gives a nice shape to the front of the seat. seat 10.png Bake the models, and then use the cutting tool as shown to...

Maloof style seat tutorial

I've been getting a few questions lately about designing a Maloof style seat in Aspire. I had a couple threads years ago, but they didn't go into enough detail so I thought I'd start a detailed thread showing my process in designing a seat. I'll include the file I end up with, so you can play around...

Re: Faceshield design if anyone wants.

Face shields should be used by all health care providers now. The corona virus is transmitted from large respiratory droplets (droplets that gravity will pull to the ground within 2m of leaving the mouth or nose). Masks are useful to protect against these droplets, but once a mask is exposed to drop...

Re: Any 5' x 5' CNC machines out there?

Let me just throw this out there. A 5x8 machine would be the same price (or very nearly, since its not custom) and if you buy a 5x5 it won't be long until you REALLY wish you had a 5x8!!! Fine for cutting 5xx5 sheets, but its no fun cutting down 4x8 sheets to fit on your machine!

Re: An Alternative 3D Finish Cut Strategy?

I would love to see some improvements on the finish toolpath! Another thing I'd like to see is to vary the stepover on vertical surfaces (like the option on the moulding toolpath). This would give far superior finish on more vertical surfaces. I'm not sure this is possible using voxels though, which...
