USB TO Parallel Port DIY Interface

[tribbles]

I've done a (very) quick hash at a schematic - with a few revisions:

1. The PIC to be programmed in-circuit with a PICkit2 or PICkit3. You'll need to make sure your CNC device is unplugged when you do this (since it pings a couple of the pins), and also don't press the switch when you do it!
2. The >400nF capacitor has been included
3. The component numbering has been altered

The new layout is smaller, and doesn't have any wire jumpers. However, it is designed primarily for photo-etching (the .zip file contains the PDFs for the schematic, layout and PCB itself, at a 1:1 scale - I use the latter for my photo-etching of boards).

If you want to remain faithful to the original design (i.e. you don't need the ICSP header), then you can replace D1 with a wire, and remove PL1.

If this treads on anyone's toes, please let me know.

I did not see any connection of 5V and ground connection into the pcb design..
But in the schematic there is 5V and ground connection,
Any one please help me...
