What a fizzer. after days of talking it up, sending us home, cancelling freight services and public transport, Alfred headed north away from us and degenerated into a tropical low in the last hour or so.

Youtube seems to enforce a 12 hour streaming limit so I had to change the URL a few times when it timed out.  Then I found a weather setting so its still up!

Notes on the tech:
My Reolink doorbell camera is managed by a Synology NAS with a bunch of other cameras (10 all up). Synology Surveilance Station allows you to stream to YouTube so it was an interesting learning curve if nothing else. The Reolink is my only wifi camera because it was impossible to get a network cable to it. Instead, I tucked a 24v power supply under the tiles above the door and used the existing wiring to power the camera. There is a chime unit which plugs into a power point inside. (I still have the horrors when I remember running 24 network cables through a 2 story house 12 years ago). I have a PoE switch in the ceiling space for the cameras mounted in the eaves.

The Synology also connects the cameras to Home Assistant running on a Raspberry Pi 4b powered by a PoE hat. That is another story.

I recently retired my first Synology NAS after about 12 years. I had replaced 2 out of 5 x 3 Tb hotswappable drives in it in the last couple of years. I replaced it with another Synology with 2 x 16 Tb mirrored drives as the number of cameras overpowed the old NAS. Sold the old one for $450 AUD!

Ich habe habe beruflich mit CNC zu tun und würde gern mal meine Fähigkeiten in Sachen Programmierung ausbauen.
Leider habe ich fast fast nur mit Sinumeric ( Drehen ) und Heidenhain ( Fräsen ) zu tun, da sich diese dort fast als Standard etabliert haben. Pal ist die Sprache die in de rAusbildung gelehrt wird und die auch die Basis für die Sinumeric ist.

Es wäre schön wenn es klappen würde.

Ansonsten ein Dankeschön für deinen Einblick, vielleicht was ja jemand nochmehr dazu zu sagen.

There is a whole thread on this subject on CNCzone, here is a description of my solution.

But it was a long time ago and all the images have bitrotted...

There are some pics of the machine here, but not the critical ones:

The basic idea is to have a T2.5 pulley small enough to fit under the cross-slide, and next to that a needle roller bearing running on a plain section of the ballscrew. Then the thrust control is handled much closer to the operator, in the micrometer dial housing, with a pair of angular contact bearings, where there is a lot more diameter to play with.

What command and feedback method do the drives and axes require/provide?

You might want to look at the "HD" cards too, such as the 6i24 as those have rather more pins. For example 6i24 + 7i36. The 7i36 can connect one smart-serial board for GPIO, and then you could add a 7i44 if one sserial board isn't enough.
Look at the 7i43 to simplify the control panel wiring too.

You might want to consider adding this to the "Contributed Components" on wiki.linuxcnc.org

LinuxCNC expects the encoder counts to be zeroed at the index. (then LinuxCNC uses the small number of remaining counts that accumulate as the axis comes to a stop to calculate the exact index position).

If your ethercat encoder counters don't do this then you will see the behaviour you describe. And, also, your home position will be wildly inconsistent.

If you have good homing switches you may be able to just not use home-to-index. Alternatively some HAL magic might be used to latch the C phase to look like the edge of a switch (and2 with the actual switch).

Reset on index might be a configurable option in the encoder counter.

You may have cut off the most important part of the error chain, the real problem is likely to be near the bottom.

Which libgpiod?

Just to let you know, that the SPI connection (generic) also works with the Orange Pi 5 and the TangNano9k.
Great work meister!

By the way I think that supporting Mesa boards would be beneficial for many, since it's much easier to adjust the functions of the pins.

Die Mesa Karte ist direkt über ein Netzwerkkabel mit dem PC verbunden. Das Kabel habe ich schon ausgetauscht - keine Änderung.
Die Spannungsversorgung erfolgt über ein 5V Hutschienen Netzteil 5V 3A

Aktuell ist außer der Stromversorgung nichts an der Mesa Karte angeschlossen.

​​​​​​Den Ping Befehl habe ich jetzt noch mit 10 Minuten ausgeführt. Die Werte sind praktisch identisch zur letzten Messung (1 Minute)

Der Fehler tritt zufällig auf. Manchmal nach wenigen Sekunden manchmal erst nach 20 Minuten. 
Unabhängig davon ob das gmoccapy Fenster maximiert, klein oder im Hintergrund ist. 
 

Not sure what's wrong, that's a 31 ms delay!

Ergänzung

Die Maschinenkonfiguration ist für die Tests ganz einfach gehalten. Erstellt mit PNCCONF XXYZ mit 1280steps/mm keine Endschalter, Spindel oder sonstige Ein / Ausgänge.
Wirklich minimal gehalten. Außer den Verfahrwegen nur Standardeinstellungen.
Die Karte läuft auf dieIP 10.10.10.10 am PC ist noch ein USB W-Lan Stick eingesteckt. Dieses Netzwerk ist 192.168.1.XX
Als Oberfläche habe ich gmoccapy gewählt.

Any plan to bring those in?
