If I run discovery on a 7i92t_7i85x2d config I get:

 

with all 4 encoders on P2

Does pncconf show2 all 8 encoders on the configuration page? like this:

 


( These should be adjusted to the actual number required to avoid wasted transfer/processing time)


For the 7I83 I suspect the easiest current way to add the hal interface code is to make a dummy configuration
for a 7I77 configuration and copy paste the analog hal an analog section from that as an example
(changing the 7i77 name to 7i83 and the sserial channel number as required)

About 8cm-ish. pretty standard dupont wires for breadboards

Hi, I have a bit of a problem getting my initial LinuxCNC config up and running. I’m using a 7i92T (flashed with 7i92t_7i85x2d.bin) connected to a 7i85 and multiple Smart Serial cards (one 7i83, two 7i84, and one 7i73).
I tried getting it configured with PnCconf, aided by this post concerning unlisted Mesa boards:
forum.linuxcnc.org/39-pncconf/52554-disc...ted-mesa-fpga#299687

This mostly worked as expected, but I have two problems. One is that only two of the four encoder interfaces of the 7i85 are shown (this would be okay for now), and I cannot choose the 7i83, which means I am unable to have any PWM channels.
This means I cannot configure the X and Z axes, and because of that I cannot finish the configuration.

I am definitely doing something wrong. If anyone knows what that is, I would be extremely happy if someone could tell me where I am going wrong.

I also attached some pictures of what I am seeing right now.

Hallo,
ich denke NativeCAM ist aktuell das was deinem Wunsch als ShopMill-Alternative am nächsten kommt.
Da gibt es ja im Forum einen längeren Thread wie man das zum Laufen bekommt. Zudem gibt es mittlerweile mehrere Github-Forks von NativeCAM.

Wenn es da aktuell nur um Drehen geht, ist dieser Thread trotzdem interessant: 
forum.linuxcnc.org/qtvcp/58056-latheeasy...-programming?start=0
Da stellt cmorley seine QT-Portierung von NativeCAM vor.

Die Frage ist ja ob die Entwicklung in diese Richtung noch so wichtig ist bzw weitergeht, da es mit FreeCAD ja mitlerweile ein sehr gutes CAD-System gibt (das deutlich mehr kann) welches direkt auf dem LinuxCNC-Rechner läuft.

Viele Grüße 
Michael

If it's open loop, the question becomes what is changing the analog out command?

Fixed the varying speed.. The source was the analog speed override pots, which are 5volt, being scaled to 3.3 and lastly 8 bit converted. 
I inserted a low pass filter with gain at 0.01 after the  analogin pin, and its magically stable.
You suggested this some time back, and as ever it was a good call. Thanks

I used to work with two machines that were stuck using older Ubuntu based Linuxcnc RTAI. Both ran servos, not stepper motors. One was because I could not get newer Linux kernels to work with the ISA IO card the machine was using, the other for extreme low latency to control torque mode servos. The ISA card machine was eventually upgraded to newer Mesa hardware and moved on to current Linux/Linuxcnc releases. The other is still running older RTAI.

I still have a machine running it. Needed for a low latency control for some difficult to tune torque mode servos. (So for the time being that machine is stuck on Linuxcnc 2.7)

Hello,I've been working on this for the last few days and now understand how to add switches graphically under user_buttons/template_main/template_main.ui (see attached photo).However, I don't know how to link the light switch to the output of my Mesa 7i76e, for example. I tried to implement net light => hm2_7i76e.0.7i76e.0.0.output-02 <= qtpyvcp.light in my postgui_hal. Unfortunately, that didn't work. What am I overlooking as a newbie? 
And in addition i´d like to have a nice looking Led right to the button. Red = off, green = on. I could not find one in QT Designer. Alternatively, the button itself could change from red to green.

Thank you for taking the time to look at that.

I will clean that up.

Now that I'm using my ethercat machine daily, I'm seeing some odd issues. Sometimes on startup it will trigger error b2 on the drives rapidly. this is apparently a timing conflict with modbus. Happens every dozen start ups.

Today i had a new one. I homed that machine, and then it began triggering joint errors and limits exceeded despite being nowhere near limits. i had to reboot the computer, and then it was fine.

If the machine starts "fine", it stays fine, but there is some flakeyness with the start up sequence.

Another thing I notice is when I tune my servos perfectly in the omron (usb) software, when they start under linux they are resonating, vibrating like 1 micron in travel. I don't know if that's a linuxcnc thing, and ethercat thing, or just a stupid omron thing.

Other than these quirks though, its great and I would not switch back for anything haha.

need that jerk control......

Hello everyone,sorry for posting a year later. I had a lot going on and put my 5-axis milling machine project on hold.Yesterday I finally managed to recover the 7i95T. Since I’m definitely not the first – and won’t be the last – to flash the wrong firmware, I’ve put together a small guide describing how it worked for me.Thanks, PCW, for describing the procedure — it helped me a lot.Now I’m a bit more familiar with the Mesa cards. Nothing comes from nothing.

Best regards!
