Kit Design of CNC Torch Table #30

Open jurra opened 6 years ago

jurra commented 6 years ago

The general overview of the Kit Concept implies the following design goals:

  1. To reduce transport costs, by providing the components, and sub-assemblies as compact as possible
  2. To facilitate the assembly of the sub-assemblies and components for the user. Make the life easier for those who want to buy a kit and replicate the machine.
  3. Make the tool head easy to exchange to convert the design into a router, a CNC laser cutter, or a Plasma cutter.

the 3. require different approach that will raise the cost though. The CNC router needs to overcome huge amounts of resistance and has to have smaller tolerances in the vertical dimension. The Plasma design has no resistance other than the friction and the inertia because it does not touch the material. Also the vertical tolerances are huge because of the torch height control.

By saying different approach I actually mean complete redesign. Belts are not good enough to that size for router, so we are actually talking for a new machine. We have to clear this issue before continuing. Router is nice thing to have, but do we need it now? Personally I would love to have a router of that size ;) ;) but I have no time now to research a leadscrew type system

The backlog items can be prioritized, if this is too complicated, or unfeasible, we can take it to the bottom of the list, otherwise, maybe some of us can take over this task.
