It all depends! From 5i25 manual

5V I/O TOLERANCE
The FPGA used on the 5I25 has a 4V absolute maximum input voltage
specification. To allow interfacing with 5V inputs, the 5I25 has bus
switches on all I/O pins.
The bus switches work by turning off when the input voltage exceeds a preset
threshold.
The 5V I/O tolerance option is the default and should normally be left
enabled.
For high speed applications where only 3.3V maximum signals are present and
overshoot clamping is desired, the 5V I/O tolerance option can be disabled.
W3 controls
the 5V I/O tolerance option. When W3 is on the default UP position, 5V
tolerance mode
is enabled. When W3 is in the DOWN position, 5V tolerance mode is disabled.
Note that
W3 controls 5V tolerance on both P2 and P3 I/O connectors.
W3 also selects the pull-up resistor voltage, When 5V I/O tolerance mode is
selected, the I/O pull-up resistors are powered from 5V. When 5V I/O
tolerance mode is
disabled, the I/O pull-up resistors are powered with 3.3V.

And ATM, I have no clue of the state of W3, whatever Peter shipped it in 
I assume.  I'll look between boards later.  Damned wood has only shrunk 
1/16" since I bought it.  But now I have 2 miss-0carved end boards I 
will have to do the matching side boards for before I can correct my 
software.

This Hartland Lumber & Planing mill stuff is half the quality & seasoning  
of what I got from Home Depot for the first chest. But while it was s4s 
1x6, this was s4s 1x12, but pieced together to make the 12, with only 
one side really smooth.  Never again, I'll take my chances and order 
from some online outfit.

On checking, I didn't have a ground on the machine frame but do now, so 
if the card is blown, its my loss.  I honestly thought I did have a 
solid ground, till I put a meter on it & read infinity.

Cheers, Gene Heskett

A hot reboot made no difference.  I'll try a Powedown Reset next.  And I 
do still have a spare card I haven't managed to install in the toy mill, 
yet...

Are the 5i25 inputs 5V tolerant?

Supposedly. I have a similar setup on the lathe, pulling to 5 volts 
because it all goes thru a cnc4pc C1G.  Has been zero trouble.

What firmware do you have on 5i25?

One of:

5i25_prob_rfx2.bit  5i25_prob_rfx2.xml

A fresh card works.

So now I am in search of a 10 foot length of 8 gauge equ flat ground 
strap, to tie the computer to the drive housing and on to the frame of 
the G0704 to see if I can absorb an ground loop spikes that may have 
blown the other card.

But in Weston, WV, they are fresh out of hens teeth...
So I expect its fleabay search time.  For a 25' roll of 6 or 8 gauge.  
Amazon had it, 1/4" wide, bought 2 25' rolls. S/B here Saturday.

[Emc-users] 5i25 miss-behaving

[Gene Heskett]

Greetings, I hope Peter is about;

I have smashed up the brass plate I use for tool length sensing, twice 
today, because the 5i25.0.gpio.003_in is not seeing a probe contact.

Worse yet, it seems to be intermittent, working well after the first such 
incident.  Changed tools, and went to calibrate the TLO for these new 
Chinese TTS tool holders, and smashed it again while descending 
at .7"/minute.

Checking with a DVM, the probe line has about 3.3 volts on it, and it 
goes to zero on the DVM when even a gentle contact is made, but  its not 
stopping the machine, and a halmeter is registering FALSE full time.

Checking the status in showconfig, it (gpio.003) is an input.  And I do 
not believe I have a separate pullup on the line, that card is AFAIK, 
doing that 3.3 volts.  Any pullups I would have installed would have 
been to the 5 volt rail.

I haven't rebooted the machine yet but will before I head out to go have 
a chat with my sawbones here in about an hour.

In the meantime, if you've any suggestions, I am all eyeballs to read 
them when I get back. :)

Cheers, Gene Heskett
