Okay. Way too aggressive on the time expectations.
I do have most of the parts here now, save a few small items. This will be a plasma cutter to start with, but I am leaving options that can convert it to a router should the need arise. It probably won't, but good to know it can be either.
Initially on the Z axis, it will have direct drive rack and pinion as well.
I have linear slides here and ball screws that I could use, but I want to see how well the simple rack will work. This is basically a CNC Router Parts machine anyway. Should work okay for plasma.
Maybe not as well if I do make it a router later.
The main parts other than 80/20 are Unistrut parts and 2" x 3" angle iron.
All the steel will be painted black. No powder coating. The CNC Router parts look fine as is. I think they will fit better without the paint or PC.
I made the parts in the drawing different colors for clarity, but most will be black or raw aluminum. I have the zinc plated Unistrut, so it will be black and not green.
This is the initial design.
I will change and add to this as it progresses.
Let me know any thoughts or suggestions. Thanks.
