Leadshine EL8 Servo motor clonking sound and motion

Category: EtherCAT

 Is synchronisation something that has to be set up on the PI or is it configured within the .xml file ?

Leadshine EL8 Servo motor clonking sound and motion

Category: EtherCAT

Show ethercat-conf.xml, please.
You probably need to add synchronization with DC clock.

Leadshine EL8 Servo motor clonking sound and motion

Category: EtherCAT

Current Setup:
  • Raspberry Pi 5
    • 3 × Leadshine EL8 Servo Drives and 400W Motors

      Problem:
      I’ve recently set up LinuxCNC on a Raspberry Pi 5 and configured it to use the Probe Basic user interface.I’m experiencing an issue where the servo drives occasionally disconnect. The main symptom is that the motors sometimes make a “clonking” sound while running, as if there’s a mechanical fault and judder under movement . Power-cycling the system (turning it off and back on) sometimes clears the issue, and the motors then run normally.
      Could this problem be caused by poor latency on the Raspberry Pi 5, or possibly by the EtherCAT network going out of sync?Any advice or suggestions on how to resolve this issue would be greatly appreciated.

Happy to hear that!
And to get feedback that the dkms driver really helps.

Step By Step Help Needed . EL8 Leadshine to PI 5

Category: EtherCAT

I haven't had a chance, honestly I don't think I could justify one ATM. The old tech budget has taken a beating already this year.
The Intel NICs sounds like a good idea.

If it's this one www.stahlwerk-schweissgeraete.de/plasmas...t70-pilotzuendung-en 
I would look at one that doesn't use HF start. You don't want HF start in cnc table.
Generally, blowback start is what you want.

Proposal RPi Linuxcnc Image Based on Raspi OS All welcome/encoraged to comment

Category: Installing LinuxCNC

I got pretty reasonable results on the RPi5 even with Wayland and LXDE.
Enough that software step generation might be an option for a mill. I was surprised by that.
I've had to go back to the basics with pi-gen, was having issues with it deciding to switch from the graphical target to multiuser.
I've got a bunch of images to test, so stay tuned.
But I think once this is nailed it will be easier to get reproducible results. You've convinced me regarding the kernels. So much easier. Thanks :)

Ok cool, git gets a bit over my head. I ain't real smart, but I used to lift heavy things .

Stahlwerk Plasma Cutters THC Interface

Category: Plasma & Laser

Hi,I'm currently on my journey to build a CNC Plasma Cutter. For the plasma source I'm looking into the Stahlwerk Line-Up of Plasma Cutters (Cut70 or Cut100). All Stahlwerk Cutters have a build in THC Connector. What I can't figure out is if this connector is already divided. Or if an external divider circuit is needed. The Manual just says that it is used to connect the cutter to a CNC controller. Does anyone have detailed information? Or own such a device at has already checked the voltage levels? Greetings

EDIT: I see there is already a workflow, but it doesn't build for arm64 or trixie, nor does it publish a github release with built packages. I'll see if I can fix that.

github actions/workflows support both amd64 and arm64, and are free to use for public repositories. I'll see if I can cook up something to build the packages using that, and pull-request it if it works. it could also potentially replace the buildbot altogether - I'm not sure if that's a good idea or not.

that said, I'm a bit short on time at the moment, so don't expect the PR tomorrow.

Proposal RPi Linuxcnc Image Based on Raspi OS All welcome/encoraged to comment

interesting, the check was removed quite a while ago . I wonder what else does it want.

as to LXDE vs XFCE, I'd probably go with the latter, it's true and tried, and almost no one uses the former - Pi OS uses Wayland and some Wayland-based desktop environment by default, I don't think many people switch to Xorg apart from us.

5-axis Isel-based machine - Logosol to LinuxCNC?

Category: CNC Machines

I've been diligently building up a 5-axis machine for machining small analytical instrument parts like fluid manifolds. My work envelope requirement is quite small. It's common to drill 0.5 mm holes 10 mm deep, and have them connect with an intersecting hole on another axis.

 

The pictured machine is wired with a Logosol CNC package (5 Logosol LS-231 drives + 1 kW spindle drive + a supervisory controller that manages door safety and more). This package is likely in many small specialty CNC machines produced around the world. I've been using Logosol's Windows based CNC program, which is free (Thanks, Logosol!) but is not really supported, updated, or documented. I've been in touch with a Logosol support person, who has been great to work with, but the software feels like a dead end. It's been great for proving the concept, but I'm forecasting a move to LinuxCNC.

The Logosol drives and supervisory controller are nicely wired - so it would be a shame to alter the reliable wiring to use ±10V or step + direction. Logosol's protocol is via RS-485, and includes 256 point path buffering.

My thought is to write HAL components to interface LinuxCNC pins to Logosol's LDCN protocol. The servo drives run a 51.2 microsecond update rate, so 20 servo ticks is 1.024 ms. LinuxCNC's update rate is 1 ms. I can either alter LinuxCNC's rate, or downsample the path points to match (feedback here is appreciated!).

I'm based in Raleigh NC, USA and welcome helpers or onlookers in my shop!

Edit: Isel is the company that made the 3 linear axes and the 2-axis A&B trunnion. They made the vertical brackets, the extruded aluminum base, and many other components. I presume they integrated the whole machine as a 'box builder', and the CNC vendor is more of an applications specialist. The build quality is fantastic.

One more note: The spindle is a Jaeger, and supports tool changes. You can see 12 tool holders dismounted from the bed + a tool height sensor.
