Considering a Full Rewire on a Working Schaublin 125 CNC

Category: Turning

I thought about this a lot since yesterday and arrived at pretty much the same solution. It is nice to have that idea confirmed by you, thanks for that.

oh and, the stuff seems to be relatively expensive.
If anyone has a project and needs a small amount (and is located in Central Europe), please give me a shout. Then I can send the rest after I am done, so it does not go to waste.

Considering a Full Rewire on a Working Schaublin 125 CNC

You don't have to cast the Moglice in place on the closer.  You could turn a piece of stock to the same (or slightly larger) OD, polish it, and use that as the male 'plug'.  

Could even make it solid stock with a threaded hole to use for pulling/pressing the Mogliced sleeve off.

And yes, Robin Renzetti's D-bit grinder was my inspiration, too.

Oh je, da kommt was auf mich zu, bis das Teil dann mal läuft. 


@andrax: Das Forum ist groß und vor allem tief in einigen Themen. Ich konnte bisher noch nichts finden. Weißt du vielleicht noch, wo du das angegeben hast?

Glad that the update resolves your issue.

But have you read linuxcnc.org/docs/html/getting-started/updating-linuxcnc.html regarding the update? It shouldn't be a big thing to update LinuxCNC.

Erste Schritte mit A6-EC Servo: 24 V für Bremse, Bremswiderstand und RJ45-Kabel?

Category: Deutsch

Relais für die 24 V DC Bremse:
Hier möchte ich noch einmal sicherstellen, ob ich das richtig verstanden habe:

Ohne 24 V bleibt die Bremse geschlossen, und mit 24 V wird sie gelöst.

Das Relais würde dann nicht das 24 V Netzteil selbst ein- und ausschalten, sondern die 24 V zur Motorbremse durchschalten. Angesteuert wird das Relais über einen Ausgang des A6-Treibers beziehungsweise über die Steuerung. Erst wenn der Servo freigegeben ist und die Bremse gelöst werden soll, wird über das Relais die 24 V Spannung auf die Bremse gegeben.

Habe ich das so richtig verstanden?
 

Korrekt. Die Verkabelung der Bremse ist im Handbuch in Kapitel 3.7.3 beschrieben. Ich glaube, der Ausgang DO3 am Servo ist per default zum Schalten der Bremse eingerichtet.

Hallo zusammen,

vielen Dank für Eure Rückmeldungen, das hilft mir schon sehr weiter.

Dann sieht mein Einkaufswagen aktuell so aus:

Servo-Set:
A6 Serie, 750 W, 2,39 Nm, mit Bremse, 17-Bit-Absolutgeber, STO
www.omc-stepperonline.com/de/a6-serie-75...a6-ec750h2b1-m17-sto

I/O-Kabel / Stecker:
HDB15-Stecker auf geschirmtes Kabel, D-SUB 15-poliger Stecker
www.omc-stepperonline.com/de/1m-39-37-hd...ger-stecker-hdb15-1m

Encoderkabel mit Batteriekasten:
3 m Encoderkabel mit Batteriekasten für 17-Bit-Servomotoren der A6-Serie
www.omc-stepperonline.com/de/3m-118-11-l...as7-c-enc076-bat-3-0

Netzfilter:
Bei StepperOnline habe ich direkt nichts Passendes gefunden. Ich hätte jetzt diesen hier im Blick:
TDK RSHN-2006
www.mouser.de/ProductDetail/TDK-Lambda/R...vzAR%252BTyPxw%3D%3D

Der Filter ist mit 250 V AC und 6 A angegeben. Da der Servo laut Daten mit 220 V AC und 750 W arbeitet, sollte das für ein einzelnes Test-Setup vermutlich passen. Oder übersehe ich hier etwas Wichtiges?

24 V DC Netzteil:
Ist bereits vorhanden.

Relais für die 24 V DC Bremse:
Hier möchte ich noch einmal sicherstellen, ob ich das richtig verstanden habe:

Ohne 24 V bleibt die Bremse geschlossen, und mit 24 V wird sie gelöst.

Das Relais würde dann nicht das 24 V Netzteil selbst ein- und ausschalten, sondern die 24 V zur Motorbremse durchschalten. Angesteuert wird das Relais über einen Ausgang des A6-Treibers beziehungsweise über die Steuerung. Erst wenn der Servo freigegeben ist und die Bremse gelöst werden soll, wird über das Relais die 24 V Spannung auf die Bremse gegeben.

Habe ich das so richtig verstanden?

Bremswiderstand
Danke auch für die Info zum Bremswiderstand. In meinem ersten Testfall geht es mir nicht um schnelles Abbremsen großer bewegter Massen, sondern hauptsächlich darum, die Grundlagen zu verstehen und sicherzustellen, dass bei Stromausfall nichts unkontrolliert absacken kann.

Gruß
Mücke

You need check for the slave-state-op and or all-op status on master, only after all-op you should even attempt to F2, connect your lcec.0.all-op with iocontrol.0.emc-enable-in

you can also make some messages with message component to tell you that ethercat is not ready.

I know the kind of driver you're talking about, but this was literally a freshly installed windows 10, and all i did was install the stepperonline software and forward the usb device to it and was able to find it in the scanner. i didn't install anything else.

I'm also having problems with the same drives. We're trying different solutions, but sometimes I hear noise from the axes as they move.
First, try refClockSyncCycles="-1"; it will definitely work better. But despite this option, I sometimes hear noise from the axes. The only way I can get them to work at the moment is with Debian 10 and kernel 4.19. I'm having problems with Trixie and kernel 6.12. We're running tests with Grandixximo and Rodw, but I'm starting to think the drives are very sensitive. I'll try Mitsubishi and Delta.

Forget my post about the adapter cable. I mixed up the servo types.

You need a USB-C cable with data transfer. Some can only charge.

According to the description, a standard USB cable is required.
After installing the software, the USB-to-serial driver apparently needs to be installed.
There are several in the program folder, but which one is the correct one?

Category: EtherCAT

VEICHI SD700 EtherCAT — Er.960 on startup, clears after few F2 presses — why?Platform: LinuxCNC 2.9.8, Debian, kernel 6.12.57+deb13-rt-amd64 (PREEMPT_RT) Drive: VEICHI SD700 EtherCAT servo drive (firmware V1.2) Interface: linuxcnc-ethercat (lcec) with cia402 component Mode: CSP (Cyclic Synchronous Position), 1ms servo periodWhat's happeningEvery time I start LinuxCNC, the drive shows Er.960 (SYNC0 synchronous frame loss) for the first 15-30 seconds. During this time pressing F2 gives:
joint 0 amplifier fault
emc/task/taskintf.cc 976: Error on joint 0, command number 56
After pressing F2 several times over 15-30 seconds, the drive eventually shows "88" (operating state), I hear a click from the motor, and everything works fine after that — jogging, position feedback, motion programs all stable.My question is: why does Er.960 appear at startup and what is actually happening when F2 eventually causes it to go away?System latencyThis is likely relevant. My machine is an AMD Ryzen system on a Shenzhen Meigao generic motherboard. Latency-test shows:
Servo thread (1ms):  Max Jitter = 85,000 ns (85µs)
Base thread (25µs):  Max Jitter = 58,000 ns (58µs)
I have tried:
  • CPU governor set to performance
  • C-states disabled via cpupower
  • nomodeset (amdgpu blacklisted)
  • isolcpus, nohz_full, rcu_nocbs kernel parameters
  • idle=poll
None brought jitter below ~80µs — likely SMM interrupts from locked-down BIOS on this generic hardware.Current workaroundUsing
sync0Shift=500000
(500µs) in dcConf which helps the drive lock faster but doesn't eliminate the startup Er.960 completely.Config filessd700.xml

Specific questions
  1. Is Er.960 at startup expected behavior on a high-jitter system while DC sync is being acquired, or does it indicate a configuration problem?
  2. Why does pressing F2 (which sends CIA402 enable controlword) help the drive clear Er.960 and lock onto DC sync? I would not expect an application-layer command to affect DC sync acquisition.
  3. Is there a way to make the drive more tolerant of sync frame jitter during the initial lock-in period — either via SDO parameters or lcec config?
  4. Would increasing
    refClockSyncCycles
    help, and what is the recommended value for a high-jitter system?
  5. Is there a known-good
    sync0Shift
    formula based on measured max jitter? (e.g. shift = 2x max jitter?)
Any insight appreciated. The system works well once locked — just trying to understand the startup behavior and ideally make it more reliable.

Haha was on the fence of buying one just because of the hype. I then went with a "cheap" Voron 0.1 kit instead. It was a pain to get it "sort of" running :-).
I am not willing to tune it to the end. (too lazy) I ended up changing the extruder, because the gears from the kit where not really good.
Now the Voron gathers dust :-) instead of a youknowwhat. ....
Question remains: is the youknowwhat really the solution to all the 3d printing let downs?
