7i92t_5abobx2d.bin should work with:

Stepgen0 --> Y axis
Stepgen1 --> X axis
Stepgen2 --> Z axis

Also in pncconf, set the number of stepgens to 3,
and the number of pwmgens and encoders to 0 to
free up the other pins so they can be used as
GPIO if needed.

 

lspci  | grep -i eth

The character after lspci is a vertical bar
( usually shift \ ), not an 'L'

Yes, I do.

X Step 4
X Dir 5
Y Step 2
Y Dir 3
Z Step 6
Z Dir 7

X Home 12
Y Home 11
Z Home 13

E-stop 10

Is the next step finding firmware that happens to match the above?  Or can I use the tool to poke the values into the right place, maybe using

--wpo     address value          Write hostmot2 variable directly at 'address' with 'value'.

Thanks so much for your guidance!
 

maybe not on the right place  but ...
i just get one 7i97t and also  two 7i84 card from eusurplus  
where can i find a wire diagrama how to conect the two 7i84 to the 7i97 and also  where and how to conect the shaftencoders and driver inputsignals 

thx in advance  

Can confirm this portion actually controlled voltage up to 10v on NVEMs (MX1052) output

net spindle-cw remora.output.09
loadrt pwmgen output_type=1
loadrt scale count=1
loadrt lowpass count=1
loadrt abs count=1
addf scale.0 servo-thread
addf lowpass.0 servo-thread
addf abs.0 servo-thread
setp scale.0.gain 0.00416666667
net spindle-cmd-rpm spindle.0.speed-out => scale.0.in
net spindle-cmd-rpm-abs scale.0.out => abs.0.in
net spindle-speed-DAC abs.0.out => remora.SP.0
net spindle-cw <= spindle.0.forward

 

 

Awesome, did you use any opto-couplers/digital isolators, are the nine 16-pin IC's only level-shifters?

What does

lspci  | grep -i eth

report?
 

My problem is not being caused by low latency due to overheating here is the temperature at the time of the error. Mach 3 would never do this using this same PC I cant get a full cut and it is very frustrating. please tell me what PCs you guys are using to not have these problems please let me know where to find instructions on how to start a cut in the middle of the file so at least cut recovery is simpler. 

no increment minus?

I agree this is complicated. Recently I got this hardwired pendant going.

The MPG, axis select and scale selectors are well described in the docs (requires small mods for a mesa MPG) linuxcnc.org/docs/stable/html/examples/mpg.html
Getting high and low speed button jogging working (selected by holding the ~  button down) proved so complicated, I resorted to writing a custom component
 

Finally, I have all the axes set up correctly. I also managed to remap the X axis keys

Thank you all very much for the help.

You can get a mapping of stepgen numbers (what pncconf shows) to pins
by looking at the .pin file that matches your current firmware.
( probably 7c81_5abobx3d.pin )

The real time delay is because you have a much faster than normal servo
thread rate (normally you would use 1 ms = 1000000 ns period = 1 KHz)

Probably the most common reason for lack of motion on step drives
is too short step pulse width.

I have a good bit of experience with CNC... built 2 machines in the past... one Mach3 another GRBL.  Long time linux admin.  Have built lots of things with RPI, New to LinuxCNC.

I am refactoring a vertical mill that I converted to CNC and Mach 3 several years ago to use LinuxCNC.  In the past I used a UC ETH-300 which of course is not compatible with LinuxCNC.  So I bought a Mesa 7c81 and an 8gb Raspberry Pi 4.

I have everything connected, Installed LinuxCNC 2.9.2 using the RPI image, have enabled SPI and it appears that I am talking to the Mesa card.
I have a standard chinese BOB connected to port 1 and plan to use ports 2 and 7 for home/limit switches, probe, spindle etc.

Started with pncconf selected my card and the 5ABOB3 firmware, looked up my stepper drivers for time, space, hold etc... 

Cannot figure out the P1, P2, P7 Mesa Card config pages as far as pins goes... expecting to assign pin2 for step X etc...  according to the BOB documentation.
I have assigned the Axis StepGen's to P1 0:, 1:, and 2: just to be able to write the config out.
When I try to test/tune an axis I hear the relay trip on the BOB which is encouraging... and when I try to jog I see the numbers changing on the Hal Meter etc but I get nothing from my steppers... they do feel slightly warm so I believe there is current going to them... but no movement at all

if I try to launch LinuxCNC using the config pncconf created I see some errors come up
"Unexpected realtime delay on task0 with period 70000" and hm2/hm2_7c81.0 Watchdog was bit.

My plan is to get basic stuff working and then add complexity... 

Wondering if anyone has a config they would be willing to share?

Or advice on where to go next... been googling and searching my tail off and figure there is something basic I am missing and once I see it properly configured I will have a big DUH moment

Any help would be appreciated!

I am running LinuxCNC 2.10.x (developer version) on Raspberry Pi 400.
NativeCAM forked by BogdanTheGeek forum.linuxcnc.org/nativecam/48857-fernv...ernv?start=10#292321 works, but only standalone, not in tab. I am not able to run embedded
I think it should run in LinuxCNC 2.9.3 too.

Edit: now, with some raw workaround it appears in a LinuxCNC tab. But it is not fully working.
Edit2: corrected some bugs  in pref_edit.py, now it works better. I cannot update the file on GitHub.
