I think this idea makes much more sense ....MagIO2 wrote: PS: would it be an option to divide the box into separate walls and assemble the box by fixing the walls with screws?

Well... that is a possibility, but I'm not sure if it will be enough robust and water cannot get in...Worldhusky wrote: Maybe he could build a little jig to keep the parts in place and use an adequate adhesive instead of screws.

In my plan, the box will be closed by a little plexiglass window, screwed and sealed with a little amount of silicon around borders.MagIO2 wrote: Still did not get the Verguss-part. Is the plan to put the PCBs inside and then flood the box with epoxy?

Nice suggestion MagIO2, I have to admit that I didn't think about thisMagIO2 wrote: Can't you cut the box in 2 pieces? If I understand you correct, only the bottom part will be housing the PCB/display. You can add some mounting holes to the upper ring and mount it with the same screws which hold the plexiglass.
I have to investigate about longer milling cutter...MagIO2 wrote: The longest tool I know so far is 30mm with 3mm diameter. But it is only good for milling foam. Anything harder and it will bend, which means you won't get straight inner walls. Maybe there are better/longer tools available for the stepcraft spindle with ER11 tool support?

Ok, I understand this. Bigger is the length bigger is the lever, so the radial force on the end mill increases when cutting the material.Rory wrote: With extra cutter stick out - comes more leverage. The point of contact between the bottom of the cutter and the spindle is then large - 50mm and this is a large lever. Its almost too much for out larger routers - and then ask to mill with SC? No way... if the machine can do it - you will not get clean lines on the passes as the machine moves down.
Yes, I understand this. Anyway, I could carve an upside-down pyramid (with large large steps) for, let's say, 70mm depth with a short-short-supershort cutting tool, yes?Rory wrote: The travel of the machine is completely different to the cutting envelope. Just because the machine can move 80mm does not mean the machine can "machine 80mm"... our larger routers travel up to 125mm but the max cutting thickness is 40-50mm and even this is a challenge.
Travel of Z axis is for access to the cutting surface. The cutting depth is dependant on the cutter, machine setup, machine stiffness, material and machine parameters..
I still cannot find data about the robustness of 3D printing artifacts... I'm quite skeptic on this, maybe I'm wrong.Rory wrote: you need to approach this differently - 3D print.
Edges? Do you mean in 2 dimensions and to assembly every part with glue or screws?Rory wrote: Or build up in 2 edges. limit the X axis cutting height to the thickness of the edges.
This is interestingRory wrote: Or - find someone with a router that can do this for you. We can cut this for you.

I think that I've got perfectly your ideas MagIO2.... mmmmh... sehr interessant... I have to think about it.MagIO2 wrote: Here are my 2 cents again
