New interesting 'LPT' device available..

Found it:
forum.linuxcnc.org/27-driver-boards/3977...terface-for-linuxcnc
-
67$ for 17 limited pins
89$ for 34 very fast pins that can do input or output on all pins
So yes, it is more expensive, by a lot.
Should have been 40, that would be very reasonable for someone in need of parallel port

Holy cow batman.

I guess there would be a device driver in the middle of it all that virtualises the parallel port. In the spirit of linux one would guess that would be open source.

Not sure where you got touse prices from but they seems to provide all you need to make one your self.
Schematic, BOM, Gerber files, programming instructions and software in a binary. So no open source but still...

It's a quite simpple design and I'm tempted to make my own PCB with levelshifters/isolators included so that you don't need another BOB to interface with the motor drivers.

We did a fully-open source Remora controller for these type of simple LPT based machines. It uses the Ethernet component as a fully real-time device, not buffered.

All design and manufacturing files are posted there.

Oh, coool. I missed that one.
Now i need to do some catching up to night.
Thanks!

Still need to pay for  "Authorisation", no details on the cost of that (unless of course you contact them via mail).
