Chinese Mesa 7I92 from aliexpress NEW

Category: Driver Boards

The basic issue is that the current firmware is just GPIO (no Step/Dir hardware etc)

There could be a couple reasons for this:

1. The wrong firmware is installed,

2. The card had corrupted firmware so has loaded the fallback firmware (which is just GPIO)

Did the card vendor supply a firmware file?, it does not look like any standard 7I92 firmware to me

If they did supply firmware, I would try re-writing it with:

mesaflash --device 7i92 --addr 10.10.10.10 --write  vendor_supplied_firmware_file_name.bit --reload

I made some comments on this in another thread about the PDO configuration, you are correct, internally it does configure the PDO's and sets the PDO assignment register ONLY if you set configPdos="true".

EtherCAT + CiA402 Servo: OP state reached, but axis won’t move (only Following E

Category: General LinuxCNC Questions

Very short explanation of how PV ↔ CSP switching works:

Only one CiA-402 mode is active at any time.

In spindle mode (PV):
- The drive receives only target-velocity.
- HAL forces: pos-cmd = pos-fb (follow-mode).
- So the axis has no position error while the spindle is turning.

When switching to C-axis mode (CSP):
- HAL switches pos-cmd from “follow-mode” to the motion planner.
- Since pos-cmd == pos-fb at the moment of switching, there is no position jump and no torque spike.

Why this is valid:
- PV mode ignores position commands.
- CSP mode ignores velocity commands.
- Therefore the drive never receives conflicting commands.
- This fully complies with CiA-402 behavior.

Status:
This configuration has been tested electrically only.  
The motors run and switch modes as expected, but the mechanical connection to the machine is not installed yet.

I still stand by my removed comment.
And I'm very sorry to say but you admins are weak and spineless to allow this buffoon to carry on the way he does.
It's a shame the CoC doesn't cover giving advice to members that is completely useless, a waste of time and potentially to the point of causing harm.
But no, the main point is not to hurt anyone feelings or to cause offense.
Who is going to have the intensal fortitude and read Langdon's the riot act. I tried in the beginning to guide him in the right direction but he would appear not to care.
You admins need to take action, I'm sick to effing death in having to make his posts an issue in the hope something will be done to rectify his behaviour. Until then I will keep raising this issue, or you can just ban me. I don't care much, Ive lost faith in every single one on the Admins on this site. You aren't doing a single thing to protect other forum members, especially new ones from his nonsense. At this juncture you all disgust me.

You did not buy a Mesa card. You bought a Chinese clone hoping to save some money then expecting help.
The best thing you can do is read the Linuxcnc documentation.
But any of the quirks with the card itself you are going to have get support from the vendor.
Without knowledge of the schematics no one can say whether it will operate electrically as original Mesa 7i92.
What you have done is bought a rip-off and now expecting those that are loyal to Mesa Electronics to dig you out of hole.

And to be perfectly honest there are plenty of threads regarding configuration, plenty of resources on YouTube and plenty of advice in the docs.

Until the issue with the 5i25 is sorted no amount of reinstalling Linuxcnc is going to fix the issue.
It's quite apparent that the config was working before. What is stopping it now from working is the error with 5i25.
It's akin to trying to get a car going by replacing the engine when the ROM in the ecu is bad.

Many thanks for the helpful suggestions! Notwithstanding the ever present Domestic Manager and her task list, I will have a go at those suggestions.
  • Cleaning and reseating the connectors sounds like a good plan. As you say, software doesn't simply evolve of its own accord. My mobo has only one ISA slot.
  • I have a spare SSD, so will do the install on that, leaving the existing system untouched.
  • "Really all you need to port across is your ~/linuxcnc folder" - I will look into this. Presumably that folder contains config data rather than executables etc.
  • If I'm still struggling with the 5i25 bit, I'll post a more focused query and perhaps PCW will be able to point me in the right direction.
Thanks again.

The problem is i dont know how configure linuxcnc. I have the doc from the seller uploadnow.io/f/9v0gkpb
This is my first time with mesa card.

PoKeys57CNC HAL component

Category: HAL

Hi all,
With Windows 10 getting slowly obsolete, and also since I also was not 100% happy with Mach4, I looked into LinuxCNC as an alternative.
I already found the other topic on the PoKeys HAL driver , however was not succesful getting Dominiks component to run.
Before reverse engineering that component, I thought to myself "how hard could it be?". I do not need many features for my setup.

Said and done, here is my own component to run a 3-axis mill: PoKeysMotionComponent on GitHub.
I still have some things in the backlog to do, but you can already use it. Hopefully it helps someone out there.

How to fix "Queue is not empty after probing"

Category: General LinuxCNC Questions

it seems to me that this is "not sporty". Together we must force the correctly given commands to be executed correctly. G38.3 should not produce such errors.
You suggested changing the interface to qtplasmac, but it uses the same g-code and linuxCNC. And I have a milling machine.
Unfortunately, my level (of knowledge) is not yet such that I immediately understand the "right path" from the hints of the M130. I would appreciate more precise instructions.
Editing the source code file, as suggested by AkkiSan and Aciera, in my opinion = the right path. And I would be ready to experiment. But I need instructions on exactly how to get v2.9.7 to use these changes.

My recommendation is to migrate your plasma machine to use qtplasmac which has obsoleted the thcud component.
It does not use g38 but probes with external offsets and also retains your probe away from the material.

I have used gcode probing for plasma without issues. I suspect your problem is related to your gcode given M130 is a custom gcode.

I would do some testing of your probe moves as MDI commands to isolate your GUI and custom gcode

Interesting to see you switching between spindle and axis.

I wonder how it works with setting a position in PV mode.
Setting position and velocity at the same time, I am not sure that works.
