You can run that card from a 7I92,7I92T,7I96,7I96S etc also

This is fairly easy to setup if the motor is always used as a spindle
(basically using the stepgen in velocity mode)

If you need both A Axis and spindle in the same configuration,
it's a bit more difficult to setup as the hal file needs to change
a number of connections, scaling depending on mode.

This signal:

net spindle-ccw => hm2_7i96s.0.ssr.00.out-00

Would need to come from the sign of the orient PID output
for orient to work in both directions (this likely requires
a mux2 and an absolute component added)

Hello I am new to linuxcnc.
Earlier, I have a servomotor from JMC : model ihsv86. its Pul and Dir signals are wired to the parallel port pin 4 and 5 respectively. the motor runs as A axis in the current setup. However, now i want to use the servomotor as a spindle. and my X axis to be a tool table linear slide.

I dont know what settings are to be done in the pin configuration in stepconfig, and what should be done for stepgen in HAL and INI files.

im keeping the post short, but i am willing to ellaborate and attach ini and hal files if needed.

help is much appreciated! Thank you

i made some changes and it kind of works but the orientation is super slow and it cant orient in clockwise direction. maybe you have some more ideas, and yes the scaling is correct

Does this look ok to get the encoder PV1 counting? PV1 should be the MPG socket. I don't know if I have a hardware issue or code issue. Also does the nvmpg.so need to be compiled first? I'm using an adum1200 to bypass the opticouplers. PV1 does not count when I move the encoder in Halshow

I would try setting up the mesa-modbus component

The 7I76E has an RS-485 interface but does require bias
resistors and the proper connections to work properly:

7I76E

RX- TX- --> A  (220 pullup to +5V)
RX+ TX+ --> B (220 pulldown to GND)

Later cards like the 7I96S Rev E and 7I76EU do no required the pullups/pulldowns

Is the spindle direction controlled by the sign
of the orient PID output when in orient mode?

Is the encoder scaling correct? (position advances by 1.00
for each forward turn of the spindle)

The Thanks belong to @Turboss, he is the VTK dragon slayer! I muddled about in it for 2 days trying to find and resolve the issue and he came in and fixed in an hour...lol he also wrote it so knows it a bit better than anyone else!
glad its all working!

Here is my final decision for pinouts:

Pause/!Resume: Pin 10
!Limit_X: Pin 12
!Limit_Y: Pin 13
!Limit_Z: Pin 15

! means logical not ("Active LOW").

What included wizards are you referring to?
LinuxCNC is not exactly user-friendly.

Debian is also kinda weird and unintuitive.
I am an Ubuntu 22.04/24.04 and macOS High Sierra user.

When you say "scrap" do you mean "recycle" or "throw in the garbage"?

It might be possible to find a new motherboard that fits in your PC chassis and works with your PSU.
That way, you wold not have to buy a whole new PC.

It might be possible to simply plug the HDD of the broken PC into a new computer.

My PC broke and I just plugged the hard drive into a similar computer (Same make and model, 1 year newer), and it works.

A new PC does not necessarily require a new installation or new OS.

However, the port address will almost certainly change.

i did just reaverse the spindle direction which i suppose would do the same but it didnt make a differance.

now it stops and then slowly starts ramping up until 1300rpm. how would i change the direction of the feedback?

Pinned.
Thank you.
