7i92.ini and hm2-pidstepper.hal pasted at linuxcnc/configs folder.
LinuxCNC, My Configuration, 7i92 and Okay opens AXIS.
It appears velocitity (inch/s) and acceleration (inch/^s) would require some adjustment. Adusted at AXIS panel Machine and Calibration, changed Stepgen_Max Velocity and Acceleration. Shown comparable at 7i92.ini file but no change Max_Velocity and Acceleration. hm2-pidstepper.hal doesn't appear to have Step, Dir and Pin Outputs. Does AXIS panel display somewhere to show ports and pins and is adjustable if required? Does 7i92.ini and hm2-pidstepper.hal require any editing? Is other or additional .ini and .hal files or a Stepconf Wizard that'd make the files for an Ethernet connection and AXIS panel?
AXIS panel
Toggle manual control, .100 increment, X axis and no stepper motor movement.
A display box 'joint 0 following error'.
What are some ideas presently just to get X, Y and Z stepper motors moving with current hardware and AXIS panel?

if you get a following error that usually means that the per axis stepgen velocity or acceleration
settings do not have sufficient headroom above the machine velocity and acceleration settings
(the stepgen settings should normally be about 25% greater than the machine settings)
You can also get this error if you try to step faster than the step timings (steplength and step space) allow

Understood. Is somewhere at AXIS panel to edit Max_Velocity and Max_Acceleration. I can edit 7i92.ini to make a .swp file. When trying to open 7i92.ini file it list the a swap file already exist and options. Renaming the file to 7i92.ini.swp and opening goes back to original 7i92.ini. How can the 7i92.ini.swp file get saved, opened and recoverable when Opening AXIS? Edit VIM 7i92.ini, Copy and Paste is only content within viewable box and Select All won't scroll entire (100%) text for Copy. I guess carefully Copy each viewable section and Paste it on some text format (or another VIM) compatible with LinuxCNC/Configs to file.
How about Ports and Pins Output too? Does that require adjustment with the 7i92.ini and hm2-pidstepper.hal files or AXIS panel, if does, where?

Forget vim and .swp files
If you want a backup, copy 7i92.ini to my7i92.ini and edit my7i92.ini with a graphic editor like gedit or mousepad
then launch my7i92.ini instead of 7i92.ini

Okay. Open 7i92.ini with Mousepad, Edit, Select All and Copy. Open new Mousepad file and Paste. Edited Max_Velocity, Max_Acceleration, StepGen_Max_Vel, StepGen_Max_Acc and Save As My7i92.ini . Toggled X, Y, and Z axis .100 incrementally and no error message but no physical movement of stepper motors. Why aren't stepper motors moving?

Are the step timings in the ini file long enough for your drivers?

Yes, such timing is about same motor tuning used with my Mach4 Hobby and Industrial interface that ran a lot of programs. Motor tuning at 64000 step/inch, 30 IPM Velocity and 3 inch/^s Acceleration. 30 IPM/60 seconds = .5 inch/second. 32000 Hz=32KHhz. I might want to experiment with that motor tuning a little more later but a while at it the setting seemed about appropriate.
Immediately, I'm not sure about the Min_Limit and Max_Limit and other specifications following between motors 0, 1 and 2. I'd have to refer to some documentation. I only edited specifications among Velocity, Acceleration and Scale as indicated. Some of the notes (#) were edited too.

I asked about step timing not step rate (these are different things)
Also a very basic thing I just noticed in your picture you have the breakout connected to P1
but stepgens 0..3 are on P2 so I would not expect any movement without using a hal file that
addresses stepgens 4,5,6,7

Yes. Not DirSetUp and DirHold. Motors 0, 1 and 2.
Presently, My7i92.ini .
# these are in nanoseconds
DirSetUp = 10000
DirHold = 10000
StepLen = 5000
StepSpace = 5000
It appears Keling 4030 specifications for DirSetUp and DirHold both 20000.

I haven't tried a connection with the 7i92M P2 yet. A 25 pin D-SUB female connector isn't available with ribbon now. I only need motors 0, 1 and 2 now. Is somewhere in .ini or .hal file that specifies a Port to StepGen and could it get edited? I couldn't find it with Search.
