Hmm... eine seltsame Antwort.
Erinnert mich an Äpfel und Birnen.
Aber erst einmal danke dafür.

Falls jemand noch etwas über den genannten AMB Motor zu berichten hat,
würde mich das helfen.

oh yes, nice thank you. I did search for it but as usual, internal search did not like my keywords.

Thanks man, i will read through. My goal is to finish the primary portal CNC retrofit and to finally build my large custom 4 Axis wirecutter But before I delve into that i want to have flushed out the processes and issues on the cnc and mesa and linuxcnc to fully understand everything.

BTW: What helps most if I basically have concrete issues. Shall i share configuration files or something? I don't want to dump blindly stuff ;D

-what should i monitor for the issue where the machine moves to a cut position and just stays there? This happens sometimes even when doing a manual cut where pressing F9 shows the machine running on screen but nothing moves. DRO does not change, machine state does. Again this happens a lot on QtPlasmaC, do not recall this happening on PlasmaC so might be a QT thing.

Again, I'd want to know if motion.eoffset-limited goes true when this occurs. I am also curious what state it's stuck in, so I would want you to turn on plasmac.debug-print before starting any cutting, etc. and copy and paste the terminal output from when it hung up.

The following commit will catch any commanded motion that would put the offending axis outside of the eoffset limits (soft limits) - this precludes you from having to monitor motion.eoffset-limited:
github.com/LinuxCNC/linuxcnc/commit/d179...e54c97ccc2bc0c58bf34

The following commit will catch any z-motion state transition issues (z-motion stalls in the same state for more than 3 seconds):
github.com/LinuxCNC/linuxcnc/commit/e2f0...30feba767f8588b2f28e

If you should encounter either of these error messages, please comment here with a recent backup of your QtPlasmaC config made from the SETTINGS tab, and the g-code file you were attempting to cut.

QtPlasmaC updates - Master (v2.10):

• update tooltips to included missing GUI elements and remove duplicate translations
• fix RFL string comparisons
• fix interlock for Material Parameters
• add z-motion watchdog to GUI to catch any state-change hang ups not caught by monitoring motion.eoffset-limited

PlasmaC updates - Master (v2.10):

• monitor motion.eoffset-limited to determine if the commanded motion is outside of the soft limits

I’m not sure how many encoders it showed on that page, I will confirm tomorrow. And thanks for the idea with the dummy config.
I will try getting it running tomorrow.

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)

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

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)

BigJohnT used to be me and hasn't been on the forum in a long time unless someone has hijacked that account.

I have not made any changes to anything.

I don't have 100% access to everything. I can not log into the ISP hosting panel. I can log into Joomla and to Kunena and have ssh access to the forum where from time to time I do apt update. I do not know how to create a new droplet and install a new OS. I'm also not a Joomla developer so it's a bit strange to me.

Also, from time to time the forum has high CPU usage that slows down the forum but I don't know why.
