Subject: RE : [Homebrew_PCBs] my crude US$170 CNC rig

APPLAUSE!!! Raaahhhhhh..... :D

WTG dude! So, are you putting a BMW or Acura logo on that? :)

"Another thought again was to store CNC milling jobs on PIC16F877-based
smartcards, if I could compress the data well enough to fit into a
smartcard's meagre on-card memory."

Have you considered using 24C128, 256, 512 or 1024 for your smartcards? You
can I2C them onto your pic. That's what I might use for my project, not
decided yet. I might dedicate a slave PIC 18Fxxxx to drive an SD card too.
The nice feature with the 18F is that it can support FAT16 (and FAT32 I
think), so that your SD cards can be browsed/editted from within Windoze. A
mini disquette with the advantage of high speed and flexible storage size
(from 64M to 8G now I think, check specs).

I just need my motors. (...Jeopardy tune...)

Any machine that does not explode, implode or catch fire by itself or
electrocute users is a successful project!

A masterpiece of precision German/Japanese engineering it most certainly is
∗not∗ :)

But it seems to be working well enough for my modest PCB requirements.

Enjoy!
