I don't think their immediate focus is lowering cost, but in reorganizing the system for distributed modularity. The basic BBB implementation is pretty low cost, though, and is in use by a lot of people for 3d printing.
They have a gui running on Android devices, so you can have a $40 BBB, a $70 "cape" that connects four stepper motors, and your phone for gui. The step pulse generation is done by the PRU module in the BBB's ARM processor. Check them out, don't rely on my summary. -- Ralph ________________________________________ From: bari [bari00...@gmail.com] Sent: Sunday, March 20, 2016 10:02 AM To: emc-users@lists.sourceforge.net Subject: Re: [Emc-users] Linuxcnc on arm How have they lowered the cost of the control and GUI hardware? I'd like to have a machine controller and GUI for less than the cost of a new low cost x86 PC and display. Is there a working BOM yet for this?
