Is there such a thing as a entry level CNC router or one that I can put together myself, that is not just a hobby engraver, for under $20k? I have inquired to a few companies and one I just spoke to (AXYZ) has a 39" x 39" Millennium (table top size) and it is $23k (supposedly complete). Now, can I build one myself, or at least part of it, that is something worth having for less than this? Understand that I am a part-timer here, but am looking to expand my capabilities. I have used CNC lathes and mills before and also am quite proficient with 3D solid modeling software. I am no machinist, but have done some work as one in the past. So, if anyone has any advice to offer, I'd surely appreciate it. I have not fully decided to get a CNC router at all, but am just looking at the possibility of one.
