Forum Upgrade #5

I think that would be a great idea anfänger, I'm also on a few other sites that have the same feature.

As long as the accounting is 100% transparent regarding where the money is going it usually works very well.

Was that a very long run? Or it just blasts them in a few seconds?

Lathe Spindle Encoder: What are the options for EtherCAT?

Category: EtherCAT

I once made a cia402pv, for switching from csp or csv to pv for spindle.
The main issues are that (some) different pins and pdos are used
in different modes, and you get following errors when switching between modes
due to how position is/isn't feed to the hal components.
The cia402pv doesn't have a bright future, but you can look there for inspiration.

Just stay on CSP if you have a normal Linuxcnc machine. CSV with pid loop
doesn't work well in linuxcnc+ethercat for technical reasons.

You've given us nothing to work with. There are many processes on Linux that can cause latency (that in turn causes your issue) but there are generally settings to turn them off. Some of them happen fairly regularly, Others might only happen every few minutes.
There is some work in master branch to create scripts to automate much of this. Some of it is not trivial.
Assuming mesa or ethercat, Main ones are isolcpus, Intel NIC coalescing and setting smp affinity for the interrupt on your NIC to your isolated CPU so it runs with Linuxcnc.

But you need to share CPU, amount of RAM,  and a latency test screendump from: latency-histogram --nobase -- sbins 1000 --show which also reports more useful info

Lathe Spindle Encoder: What are the options for EtherCAT?

Category: EtherCAT

Hello everyone,
A small issue came up with the Lichuan servo motor I ordered on AliExpress. The seller turned out to be a scammer (the listing had way too much off-platform contact info) and was luring buyers in with the lowest price. After I paid for the servo kit, the seller contacted me via WhatsApp claiming that shipping was too expensive and demanding that I either pay an extra $60 or cancel the order—even though the listing advertised free shipping. Naturally, I replied that all order-related communication must stay on AliExpress, and if he wanted to cancel it, he should do it himself or fulfill the contract. Unsurprisingly, he had no intention of shipping it; instead, he either faked the shipment or sent an empty package. The parcel never left China and was returned to him, and AliExpress eventually refunded my money. So I ended up without a motor for my experiments and lost a lot of time.
Fortunately, I stumbled upon a much more interesting used servo motor for just a little more money, which I bought and have already received. In the end, things turned out even better—I now have a 1.5 kW Omron motor for the price of a 400–600 W Chinese Lichuan.
I've done some initial setup and got it running using the IgH + lcec + cia402 stack. I ran it a bit through the terminal in velocity mode—I really liked it and will keep digging deeper. Right now, I'm interested in learning how to switch modes on the fly: transitioning from cyclic synchronous position (CSP) mode to velocity (CSV) mode, torque control (CST), etc.
I also tested running the EtherCAT + Mesa setup together using a separate network card.

I am amazed at the response to the forum funding. Never in my wildest dreams did I think this could happen but everyone here and on the IRC are pulling together to make a better forum and a much stronger LinuxCNC.

Thank you all

No, the upgrade went perfect.
So why did we revert to the old forum, losing threads from the last few days?
 

No, I accidentally deleted all of the posts one category except 1. Instead of the desired trim of 5 years I trimmed to 30 days which is the default span so only one post was left and most of the posts described machine builds.

Category: Milling Machines

Hello Andre, Would you be willing to share your schematics, or tell me which machine and revision they cover? Even photos or scans of the pages would be a big help. I'm also happy to pay for your time or share what I document on my side.
Thank you very much!

It’s just that experience has taught me that trying to upgrade something old usually ends up with something wont works.

I have a LOT of old machines that were upgraded and work much better.
I am old and i do much better work now than when i was young, no idea when the upgrade happened! :)
