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.

What would be the best eps32 to test this application?

Wait till you start playing with HAL, that is a whole new world of possibilities!

I read here on the forum about eps32.
What project would you recommend to me to work with 4 to 6 axes?

What is the issue with inputs 3..7?

They work as expected for me

(they do need pullup or pulldown resistors for use with switches however)

much better thanks

I dont have the hardware for the rt1052, but most units arent directly controlling an analog voltage, but rather sending a PWM to an opamp which makes 0-10v. When this is the case, the PWM signal is out of 100, so PWM 100 = 10v = max spindle speed. From the configs Ive seen for the RT1052 I will assume its the same, but I cannot find an example that says otherwise.

many thanks this way I can keep a lot of my own ui stuff just need to move it.
QtDragon seens to be a bit more flexible there.
I really like the look of probe basic and it's now my 3rd machine using it.

My adaptations are usually quite unique to my machines caus they are retrofits of old industrial machines.
I had a basket tool changer and a turn table and automatic doors. (but this machine is gone)
Then there is the partial manual three stage gear box on my lathe in combination with a vfd
An om my current machines the lube and column system.

But what i uses al the time were leds for all the IO's. this helps trouble shooting.

What like is the setup sheet. I think you wrote the bits for me and it didn't get into production.

and I started on the lathe macros with saving the parameters. but I ran out of patience and time.

For me this all is just a hobby and in the past year and a half I had even less time cause I am living in two places until I got my building permit and have the new workshop prpared to move my shit.

Sorry if I was impatient I kind was hoping that it would be just one or two small things i need to change.

And then I looked into alternatives and the documentation for qtdragon was a bit easier to unterstand ho to customize for me. And it looks a bit more flexible.
But lacks a lathe interface and I still hope I can copy pate some of my shit in the custom tab and get it running.
I am kind of lazy when it comes to doing work twice.

And I need to thank you guys for being open source linuxcnc and probe_basic is really impressive and a really great piece of software.
Many thanks for all the work and kind support I am getting here

In this case the control box contains the breakout board

There is no need to re-route signals, you just need firmware that
matches the required pinout.

Firmware is updated with the mesaflash tool, but the first step
is to determine the required pinout of your breakout

Do you have this pinout available?

(a working hal file created with stepconf would include this information)
 

Any idea about the pin out for spindle 0-10v output? PWM I noticed in your config/other pinouts but voltage based seems to be missing.

Thanks again

Hi
I use 7i73 and now I use   IN9 - IN13   for pendant input(For Sellect X, Y,Z, x1 , x10)  and use IN14 and IN15 for encoder pendant 
Now I use all bit input.
Now I connect resistor IN3 -IN7 for pull up done.
I want to use IN3 - IN7 for bit input but it's can't recieved  0 , 1 for trig signal (IN3 - IN7 analog input). 


How to setup ini ,hal for use IN3 - IN7 for bit input or trig signal ? 

 

Thank you ,
Asis

There is no breakout board - the K2 has a control box with a DB25F on the back. I could probably crack it open and see what it's running inside. From there I could likely re-route the lines to bring it back to "standard" pinouts. But it feels like this should be a .hal thing.

When you say "choose firmware" do you mean the firmware on the Mesa card?

Is this something I can configure via the Mesa Configuration Tool?

I agree. My project is in the stand stage on the table. But it works within its limits. However, It's not ok to not have a normal touch when it should be the default.
