Wenn er frei beweglich ist dann passt schon der enable nicht. Nennt sich auch son oder servo on

Hi all,  

please guide as how we can add .py files as codes for user buttons in qtplasmac interface. The code works ok on terminal and base machine in raspi 5.

thanks

That's what I kind of figured. I'll have to run a temp bypass on the SSR for now and also re-think how it's wired to keep the vfd on without the control program running. The old vfd was analog so this never came up before
Thanks

I wired it so that if the control was closed or the e-stops tripped, it would cut power to the axis drives and spindle vfd. The enable button on the screen does as you say. 
until now I've not really wanted the vfd powered without the control software running so it wasn't an issue

Wrong thread. Sorry, deleted

The Schaublin tailstock has no sensor, and a very large and long nose. Everything is so large reletive to travel, that you dont even need the tailstock that close to the saddle for a turret tool crash.  I'll take a look at fitting a switch to detect the tail stock installed. It might be best to inhibit the tool changer as long as the tail stock is mounted. At least initially.

How do those lathes deal with the order of motion? A Z clearance move first followed my X makes sense for boring tools, with the opposite for turning tools.

Hallo,

ich versuche gerade den Einstieg in LinuxCNC, um eine kleine Maschine mit zwei Linearachsen (Kreuztisch) zum laufen zu bringen.
Dafür würde ich gerne zwei AC Servos verwenden, komme aber nicht mehr weiter.
A6-Serie 400W RS485 AC-Servomotor-Kit 3000rpm, 1,27Nm mit Bremse, 17-Bit-Absolutwertgeber IP67 - A6-RS400H2B1-M17 | StepperOnline

Ich bin mir nicht ganz sicher ob das Problem an meiner (ersten) Linuxcnc Installation bzw. Konfiguration liegt, oder am Servotreiber.
Hardware ist ein PC mit Mesa 7i96 (ohne s) Karte, die per discovery auch erkannt wurde. 
Wenn ich im Pncconf wizard bei X Motor "Test/Tune Axis" versuche oder über die UI den Motor im Jog Modus bewegen möchte passiert nichts.
Der Motor bleibt auch frei beweglich und hält die Position nicht

Im Gegensatz zur Software von Stepperonline, wo der Motor sich manuell ansteuern lässt.
Hier kann ich aber in der Software auch den enable Schieber aktivieren.
Ein Enable Pin wird aber nicht explizit erwähnt, auch hier im Verkabelungsbeispiel nicht:
A6-Serie 400W RS485 AC-Servomotor-Kit 3000rpm, 1,27Nm mit Bremse, 17-Bit-Absolutwertgeber IP67 - A6-RS400H2B1-M17 | StepperOnline

Ich hätte den Treiber differentiell angeschlossen, wie im Datenblatt des Treibers auf Seite 44 dargestellt.

Bin ich zu voreilig den Motor direkt drehen lassen zu wollen und sollte erst mal tiefer in die Konfiguration meiner Maschine einsteigen, oder übersehe ich beim Servoantrieb selbst etwas?
Leider zwei unbekannt, da ich bisher nur GrblHAL in Verbindung mit CL57Y Treibern verwendet habe.

Viele Grüße,
Martin

 

Yes, all 7I76 output pins will be forced off when communication stops.

Thanks, after a few tries I managed to get it to work, but only for a few minutes. Then it would disconnect and reconnect until it froze completely. Now the USB stick is no longer detected and it also blocks the mouse and keyboard when I insert it.

Hi,
i am verry new to LinuxCNC and want to build a machine. The Axis will be made with Stepperonline A6 Servos with ethercat. But i´m stuck at the ethercat configuration, as I basically dont know anything about it. All i know is that i need an .hal, .ini, .xml and .conf file. I have already installed the ethercat drivers with the guide from rodw and can set the preop/ini mode via the Ethercat slave ... command. What do i do next? I have opended and created a machine, with the axis sim preset, now with the folders in my home directory. How do i create the needed files and integrate them, so it works? I have looked through multiple topics on the forum, but cant get any wiser with them. As I said, total beginner. Any step by step help much appreciated.

Thanks.

I moved the voltage divider to the first stage and put a zener after it for overvoltage protection like Hakan.

@tommylight: Do you have a schematic you can share that shows how you use 3 resistors for voltage division. I'm having trouble visualizing your description.

Here's where I'm at right now. I need to add SPI isolation. That's going to be the biggest stage of all because there aren't any good through-hole all in one solutions like there are for SMD.

As a result, I started experimenting with Z-axis acceleration settings to reduce braking time. Previously, the acceleration was set to 2000. When I set the acceleration to 6000, no errors occurred over 14 hours of operation (115,000 measurements). When I set the acceleration to 12,000, I got an axis misalignment error. It works acceptably at an acceleration of 9,000.
