So how many hours of labour for you to create a completely functional LinuxCNC with two parallel ports on 26 pin ribbon cable connectors that can be swapped into existing BoBs?
And, a user interface that mimic's MACH3 so you can then market that to the thousands of MACH3 users who's WIN-XP systems are starting to get a bit long on the tooth. The interface would have to be able to run the same Visual Basic Macro's that they may have written (or bought) to run special features. People have been fooled into thinking that cheap hardware (or cheap shoes, clothing, TVs etc) should be the norm. Building just the hardware, made in the far east with $1/hr labour and no environmental/labour standards certainly gives the rest of the world cheap hardware. But assume you are worth $100/hr. If you do it all yourself working 40 hours per week you really only have about 2000 hours available. That's $200,000. Now build just 100 units. To break even, forgetting about pennies for the hardware you have to charge $2000 per unit. And that's assuming you can do everything you need in 2000 hours. Just because someone builds at a few pennies above cost a product for $35. Doesn’t mean that the end product costs $37.95.
