How about a mycncuk cnc router project?

Jazz, As has been stated the idea would be to keep it simple, very rigid and straight forward to build. I am aware that cutting ally would up the anti, but it also vastly increases the scope of the machine, and would be useful for a "future" Monster build.

How does vertical work? material hold, retaining cutout components etc., would it really save any space? - I suspect not. best keep it simple, which probably
means conventional, although its good to think outside the box.

IMHO the best choice for the frame would be hot-rolled section, either steel or ally (both of which can be of welded or bolted construction, although ally welding requires more skill). How does a braced channel section compare with box or RHS for strength and rigidity?, this may be easier to make stronger bolted connections - just thinking out loud.

Yes it is difficult at this level, but that is probably why most available kits etc. don't quite cut the mustard. Also the idea behind this suggested project.

This machine is intended to be an improvement on anything currently available so I don't think MDF comes into the equation. I am sure some people have achieved some success with MDF, but do not feel that it is suitable for this particular project.G

Geoff your falling into the "Bridge too far" trap.!! . . . Theres cutting Ali and cutting it correctly and I'm not guessing when I say it can't be done complete and working with spindle for under 1K and keep the simple to build Ideal. If this is really a design requirement then I'm out has I don't have time to waste on what I know can't be done.

Vertical works just the same has horizontal regards work holding and part cutout.? All material needs clamping even when horizontal, esp the cut part. You wouldn't leave a cut part unfastened so it could be dragged back into the cutter so you'd clamp,stick,tab etc to hold in place which applies just same when vertical.
The space saving is considerable when the machine size rise's but even a small machine could be large space saving when hung off a spare wall thats just holding up a roof.

Look round your workshop and find a wall with enough space for slightly deeper than your typical Kitchen double top cupboard and thats your CNC 600x600 machine.
Now look again and find a space on the floor or bench for 1sq meter with space in front or at side to stand and load/operate machine and see the difference.? . . . . What was you saying about no space saving.!!

Oh and 90% the chips fall away so you can sell that great big Vac needed before and get a nice small one for the bit thats left.! Put a simple frame with doors on front and it's clean and quite with minimal impact on workshop.

Jazz, I take your point about the trap. I never intended a design that was specifically to cut ally, ally was at the end of my list of materials to cut. The machine would be primarily to cut softer materials, but if capable of cutting ally occasionaly using light cuts it would be a bonus. If that is not possible it would not be the end of the world and as I have already said I suspect ally would need a different spindle. - Don't drop out Jazz -your input is highly valued.

I usually cut MDF,ply and pcb matrerial using my newly built vacuum table and I suspect that I would struggle to keep loose pieces in position, hence my comments about the vertical machine.

I am not aware of a small vertical machine, so perhaps something like that would make it really stand out from the crowd. Gravity chip clearance sounds
interesting.

It would be nice to hear a few more people commenting on the feasability and and specification of the machine.

I was not wanting to specify the design myself, only to get some discussion going and then to come up with something.

Even the 1k ish price was not a given, just a figure that I feel would generate some interest if achievable. G.

did you watch the video i linked of jazz's vertical machine?
