You are never out of line and always have the most excellent suggestions!
Fantastic question! Actually the Control Panel was intended for a lot of different types of machines. For example, the Tools Tab uses X,Y,Z,A,B, and C offsets. This was specifically with lathes in mind.
On the short list is support for threading, including rigid taping (both very close to the BitSave functionality already there).
Sleep? What's sleep? Seriously, just trying to cover all the bases. Now, I'm sure I'm going to goof something, but it won't be from a lack of sincere intent .
Purse!! Wow! CNC Brain is really inexpensive. The Brain was designed to return the cost of the device very quickly.
Yes. About 200KBytes. It uses the memory primarily for caching instructions, look ahead, and ... the key point ... dealing with the USB interface.
The CNC Brain, through the MPP, is a little different from standard processing. In a PC, the processor uses memory like a filing cabinet. In the Brain (which is why it is named such), it resembles the functionality of an animal brain ... everything parallel. So, while the PC is doing the "bit shuffle tango" with the memory, the Brain just does it.
