If the RPi can use SPI over a 250mm length cable at rated speed then it is a
great option.
No? How about a 150mm cable?
If the signal can't get off the host PCB and to the target PCB reliably then
the whole issue is a non starter moot point.
Maybe if there was an

You have a point, but there's probably more paraport BOB's available than
the 4 wires spi boards. Probably less $$ for a simple paraport BOB.
But, I do like the SPI 4 w

I think on the pi-3b, spi is likely faster than a parport. Thats how I'm

What to boot off a hard drive? Try "TFTP". The hard drive is physically
connected to some other computer on your network and the Pi uses the
network to access it. TSTP is the boot protocol used.
At one place I used to work the IT department set up user desktop PCs to
use TFTP to book a standa
Has anyone played around with this: Pi-paraport

I had been wondering if a paraport emulator or an SSerial adapter could be made
for the Pi GPIO
The new question is can it be shoehorned into a realtime environment.
I was thinking a ODroid XU4 imaged with

Way back when I was making the transition from Slackware to Red Hat I teamed up
with another local fellow on a little project.
He was much better with disciplined technique than I was. He kept a spiral
notebook for each PC and would copy down the entire line, file path and

Why not do the same thing for "free" with a g-code processor that sets all
Z coordinates to some constant. No hardware required, just a few lines of
Python or whatever you like.

I know, I was here when you were building it, but for some reason I
thought you were writing about a different machine. Can I blame it on
oldtimers? Or as you stated in an earlier msg, CRS? BTDT, several times

Well that's certainly a failure in design / programming by the manufacturer.
I'd have it so that when re-enabling Z the first and only thing it would be
able to do is rehome Z up so it knows where Z is. Even if the manual says the
operator has to power cycle and rehome everything after using Z d
