Planning to purchase a CNC . An recommendations ?
In all honesty, you are starting at the wrong end of the question. A CNC is nothing more than a tool...albeit a very specialized tool...and it must fit into your business model, or it will become a very expensive boat anchor.
1) What do your customers want/need? Are their wants and needs realistic, and are your capabilities realistic to produce said signage?
2) What is your budget?
3) What are your shop capabilities (voltage, compressed air, work area, etc....)
4) What are your primary and ancillary software, tooling, and equipment needs?
The list could go on, and perhaps others will chime in.
Choosing a CNC needs to be a very highly cerebral decision. Stay the hell away from any trade show until you have a solid understanding of what you really need. Trade shows play high on emotions. And before you know it, you're buying something you really shouldn't.
If you do happen find a trade show featuring viable vendors, make a long check list FIRST, and go over every line item with the rep to see how it stacks up. Honestly, you can do a lot of homework online before you ever set foot in a convention hall.
