Hmmm. $50 + $89 or so for the Mesa Ethernet Anything I/O card. Two weeks at 80 hours x $100/hour = $8000 Or, surplus PC $25 + $89 for the Message Ethernet Anything I/O card + LinuxCNC Live CD ($1 for the media) and cables to existing Break Out Board which are needed for both systems. Why even bother with the Allwinner board when the PC has the power supply, expansion connectors, DVD drive etc. The only way you will see these small cards work is if they are part of a larger PC board that does what the BoB does. One board to run the CNC system and it has to come in under $100. The market just isn't there or MESA would have done it already. > > > On 6/13/19 12:42 PM, John Dammeyer wrote: > > 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.
