That particular 400K version was made specially for me, because I needed
step/dir signal from stepgen to be routed through "sense A" and "sense B"
lines on 7i39 card.

While I don't need to add a new project at this time this does peak my
interest, but it brings up some questions. What type of capabilities
can we expect to get by retrofitting one of these older NC machines?
I would think they should be more capable than a "Chinese mill"
conversion but what
Peter, would it be possible to make 7I43/7I39 firmware for 200K?
Now it appears I need it..
From the other side - how to use svtp4_7i43-200 with 7i39? I think
there will be different pinout, at least..

Do you mean 6i25?
There are many 6i25 firmwares that output step pulses, those are
always FPGA-sourced rather than daughterboard sourced.

I need to output quadrature stepping from a 6i25. Do I have any options
in this regard, other than bit banging or external circuitry? Thank you.

The only problems I have had with pins is when I assign more than one
thing to drive them (ie: both the PRU and the hal_bb_gpio driver) or
get the muxing wrong in the device tree overlay.
The PRU can talk to any GPIO pin on the device, as well as the

P8.36: All of the docs that I've seen don't show this pin being assigned to
a pru. Does this mean that it isn't available to use with the PRU based
pwm generator? It looks like it might have been used with the build-in pwm

.75 mm^2 is a light. I probably would have gone with at least 1.25 to
1.5 mm^2, but if you have rung out the cables for continuity, that is
not going to keep things from moving. And this setup was working
before.. right?
Igus sells some very nice shielded trailing (Hi Flex) cables for
reasonab
Of course is not the shield the problem!
The issue is that the cable used seems to be not ok.
Shield is anyway a must for servo applications.
And a flexible or extra flexible is a must for mobile cable chain/tray.
I know about cables not working after time due to mechanical stress.

However, the problem here is nothing to do with lack of shielding.
Did you check for pin-to-pin shorts in the wiring?

First all the cable must be shielded.
Secondary fot this kind of application you need at least flexible shielded
cables.
If you search for on google I am sure you will find many cable
manufacturers for that kind.

This is motor datasheet:

oh sorry .
Sure you already did it .
Sometimes appened that you can measure the cable resistence with the
multimeter
and everything seems ok but after that if you apply voltage to the wires
the problems come .

In "n" mode the system should be acting like a dumb vfd, and no
commutation is used.

That's odd.
There's a good, cheap gear generator program here:

This is for 3-axis machines.
It has a lot of nice features, including planetary gears, lantern gears,
and even roller chain sprockets.
