In looking at what I have, vs what I need, I need a bit file for
5i25's
with a 7i76D driver on P3, and a std parport bob on P2.
There are pre-existing 5i25_g540_7i76.bit and 5i25_7i76_g540.bit
files. (7i76D is the same pinout as 7i76)
Those files do not exist in the 5i25 downloads I have dl'd from PCW's
web page at mesanet.com. But the latest copy is dated 2015. Duh!
So I pulled a fresh copy. And there they >are! So thats going to be
a help. Thanks Andy.
he gs540 I take it, works with the std 5 axis "Mach" bobs like the
Sainsmart. That might need some hal editing, but would be ideal if
thats the case. Bringing all of P2 to the menu >for tool changer and
such stuffs. That will encourage me to get to work on that when I
better and bored.
Peter wants me to rejumper this whole rig so that all the 5 volts is
powered from the 5i25. We'll (I've a mouse in my pocket) give that a
shot tomorrow.
Everything has its own 5 volt supply right now, so is never powered
down to reset unless I pull the line cord to the interfaces box
which ATM I've not yet done. I'll check my >inventory for a switch,
could be all I need is to reset everything with a power switch
cycle.
Thanks Andy.
Cheers, Gene Heskett
You can't set the 5i25 to supply 5v to the parallel port BOB, it will
short out the 5v supply. (parallel port BOBs have those pins all
connected to ground.)
Now you have tickled my curiosity bone, Todd.
I /think/ the SainSmart 5 axis bob does give you a choice, but I've never
intentionally used it. I'll have to check the docs as I've several
copies in the garage. In any event I don't think the SainSmart bob is
smart enough to need a reset anyway. The Mesa 7i76D however does need a
full powerdown. The question then becomes how to I power the 7i76D from
the 5i25 as I don't believe I can control the power to P3 and P2
independently. So for testing, the p2 will need to be disconnected.
Yes, you can see page 2 of the 5I25 manual:
W1 (P2 POWER ) W2 (P3 POWER)
UP UP BREAKOUT POWER ENABLED
DOWN DOWN BREAKOUT POWER DISABLED (DEFAULT)
N! ways to screw it up just grew by one. Sigh...
