Acceleration has nothing to do with it.
Only maximum speed matters.
From the resolution and speed you will calculate the pulse frequency.

Hi PCW,

Thank you so much for the incredibly fast reply!

I will add setp hm2_7i97.0.encoder.muxed-sample-frequency 20000000 to my HAL file right away and test the machine.

Just to make sure I fully understand the limits of the hardware: what are the acceptable or maximum values for this parameter with the standard 7i97T bitfile? For example, does it need to be a specific integer divisor of the base clock? Also, at what frequency would I typically need to start adjusting the muxed-skew parameter you mentioned?

Thanks again for your time and excellent support!

I would try setting:

hm2_7i97.0.encoder.muxed-sample-frequency

to say 20 MHz

(you can probably go higher by futzing with the muxed- skew parameter)
 

mesaboard is on 2. enp8s0 (see alsö static inet/inet6 addresses) It does show no carrier when unplugged.

eno1 (internet) has automatic connection method.

wlan has been turned off in order not to get confused.

I changed lan cables and now it behaves as it should mesact/machine finds the board and readhmid provides the information as expected.(mesact and terminal)
I wasnt aware of that since I did have acces to the internet anyhow(???).

so thank you very much for the moment This particular problem is solved.


Have nice days

please find attached 3 screenshots - left side are all the pins for cia402 component (they did all fit in screen) and right side is list of lcec pins in terminal. do you have any idea, which of these is "enable" pin? lcec.0.state-preop, lcec.0.state-safeop and lcec.0.state-op seem suspicious to me but then I do not understand why would 3 pins be needed. I would appreciate some hints on which pins should I try for enabling the drive and which would be most suitable candidate for making the motor spin. cia402.0.velocity-cmd would seem like most obvious candidate but is there anything else to add (so far in my experience it would have been 2 pins - one sets velocity, the other would be a bit output for "run/stop")
BTW cia402.0.controlword has value 4, which seem to match instructions in manual to set the parameter 50.04 to 4 (which means that reference is speed). does that help in any way? and since the manual says this:"Ensure the drive profile parameter 51.02 is set to CiA402 (0)" I would like to think that it's all good regarding the suspicion about needing different mode rather than cia402.
could you please share some link where I could see some cia402 templates that you mentioned?

I just try to set the card to work.

For the beginning, I want it to get a single stepper motor to turn with nothing else connected to it. For this, I need to configure some hal and ini files. I can use mesact but not pncconf for this.Later, I will analyze and try to understand these first files according to linuxcnc docs. What i intend to do is retrofitting a lathe to cnc (two, maybe three axes) , an additional axe for an attached lathe and on for a dividing head and some encoders /DRO This is all I might need in the (far) future.

Right now, I would just be happy to get linuxcnc, mesact ,board and stepper (driver) "Talk to one another".

cheers

OK so the next question is which Ethernet interface is the 7I95T connected to?
(enp8s0 or eno1)

(quick way to check is unplug the 7I95T RJ45 cable and see which interface shows "NO-CARRIER"

copy from terminal :

Sorry, i forgot to ask, why would you flash the 7i95T ?

IMHO GUI's should not be included in the main repo except for Axis so as to not drag in a huge amount of dependencies for nothing.

If anyone asked me to decide what way to go, i would be very hard pressed to decide as i see benefits on both sides.
Should i elaborate?

Hi FOrum!

i have a Foxconn A74 Mainboard with 4GB DDR3_Ram, AMD Athlon X2 250 3Ghz.
I tried to upgrade to a graphicscard, i bought an Asus Radeon R7 240 with 2GB of DDR3 Vram.

Now my problems.. The latency overall is the same as with the onboardgraphics, bit i have massive spikes, up to 600000..

I tried: 

1.  Grub "radeon.dpm=0"
no luck, LinuxCNC greets me with a Readerror.

2. Grub "radeon.si_support=0 amdgpu.si_support=1 amdgpu.dpm=0"
no luck, LinuxCNC greets me with a Readerror. I checked which driver is used, it was amdgpu, but no luck.

As far as i can tell, the version without any kerneltweaks worked the best for me.

I have 1 Core isolated for LinuxCNC, nothing fancy in grub customized. 
Is there anything i can try to get the graphicscard to work properly?

Thank in advance, greets, TOm

Ich freue mich auch sehr darüber das NativCAM eine aktuelle Überarbeitung bekommt und bin allen dankbar die daran arbeiten.
Ich bin jemand der auf einer CNC umgebauten Langlochbohrmaschine Kleinigkeiten bearbeitet. Das was halt so in einer Tischlerei anfällt...
Hierzu ist NativCAM ein top Programm dafür.
So ähnlich wie WoodWop für eine Homag Maschine. Hier wird auch vieles an der Maschine programmiert.
Ich bin mir sicher, das dieses Programm künftig noch viele Möglichkeiten bietet. Ich werde mir mal die neue Version installieren und mich damit intensiver beschäftigen. Die derzeit installierte Version läuft leider etwas labil.

Danke an alle die diese Software am leben erhalten....

board adress changed to 10.10.10.11 and ping to 10.10.10.10 gives destination host unreachable. Ping to 10.10.10.11 is successful.

Are you changing the board IP or computer IP? Board address is changed using mesaflash, and there is never any reason to do it.
Computers address should be changed depending on the Mesa jumper setting, be it for 192.168.n.n (default) or for 10.n.n.n if you change the jumper as per the manual.

I remember rumours different regions or countries might require specific ip addresses in order for this to work

That is not true, both subnets used by Mesa (10.n.n.n and 192.168.n.n) are non routable IP addresses so they do not go out of the local network, hence have nothing to do with region or localisation.

The procedure you suggest in this thread does not work for me.

It always, always works if you follow it properly, so what does PCW's advice return?

What does the command:

ip a

return?
