If mesaflash reported that error, update mesaflash
(instructions on the git site or above in this thread)

github.com/LinuxCNC/mesaflash

If LinuxCNC reported the issue, you need t o update LinuxCNC.

(You don't actually have to update LinuxCNC as it will work fine but will complain about the card every time you start LinuxCNC)

I'm having the exact same problem, has anyone figured out what's going on?

Tks

I swapped computers for a i5 and now it all works fine, thanks!!
Perfect!

It's not a laptop, it's an i3 mini PC, I'll swap it for a i5 I have laying around and see what happens.

I'm a huge fan of your videos, I was actually watching one of them when you replied!!

This PC may not be suitable. Is it a laptop? If so, replace it with a desktop.
There is no simple fix as it is a culmination of things required to tune the RT Kernel.

Hallo

Seit langen wieder eine Frage.
Meine aktuelle Eckdaten.
-Lenovo W520 
-Linuxcnc 2.9.8  auf Debian Trixi
-Mesa 7i76e

Ich habe folgendes Problem.

Meine Servo thraed schiesst  sporadisch in die Höhe und es führt zum Abbruch von Linuxcnc.

Meiner Meinung scheint der Netzwerk Controller Intel 82579LM sporadisch zu aussetzer von rund 1Sekunde.

Jetzt ein paar Fragen.

1.Welcher Treiber wird von Debian Trixi  für Netzwerk Controller Intel 82579LM benutzt?
   - e1000e ???
2. Wie soll ich folgende Abfrage "ethtool -c enp0s25" interpretieren  ?

Ausgabe:
Code:
Coalesce parameters for enp0s25: Adaptive RX: n/a  TX: n/a stats-block-usecs:    n/a sample-interval:    n/a pkt-rate-low:        n/a pkt-rate-high:        n/a rx-usecs:    0 rx-frames:    n/a rx-usecs-irq:    n/a rx-frames-irq:    n/a tx-usecs:    n/a tx-frames:    n/a tx-usecs-irq:    n/a tx-frames-irq:    n/a rx-usecs-low:    n/a rx-frame-low:    n/a tx-usecs-low:    n/a tx-frame-low:    n/a rx-usecs-high:    n/a rx-frame-high:    n/a tx-usecs-high:    n/a tx-frame-high:    n/a CQE mode RX: n/a  TX: n/a tx-aggr-max-bytes:    n/a tx-aggr-max-frames:    n/a tx-aggr-time-usecs:    n/a

3.Warum werden nicht alle Einstellungen angezeigt?
4.Kann man den Netzwerk Controller Intel 82579LM so einstellen, das ich die Aussetzer weg bekomme?

Ich hoffe mir kann einer von Euch was zu diesem Thema sage.

Gruß Califax

hm2/hm2_7i76e.0: was created by Estley
I'm starting a PrintNC build, as far as the control side, my setup is as follows:
  • Dell Optiplex 3040 (disabled all power management, VM and internal wifi fron BIOS)
  • MESA 7i76EU
  • DM556Y from stepperonlineI created a new configuration in linuxCNC, and connected one of my drivers and steppers to it to make sure i was doing things correctly, I can jog the stepper from the UI, but after a few seconds I get this:hm2/hm2_7i76e.0: error finishing read!I'm new to all this so i have no idea where to even look, thanks!!

so far all works well, you did a great job thanks. for now this will do.

The current firmware puts the PWMgen on P1 pin 1

If you want the PWM  on a 7I85 RS-422 output, that would
require different firmware.

thanks a lot. tomorrow i try if it works. it is getting to late. the 7i85 board is not connected yet. i first want to make all working. then i will connect the encoders on the motors and connect the 7i85 board. what pins do i use without the 7i85 board to use the pwm?

7I76EU firmware for 7I85 on P1, and 1 PWM on P3

 

File Attachment:

File Name: 7i76eu_7i7...1pwm.zip
File Size:297.74 KB



After doing this I also had a thought that you could use a spare RS-422
output on the 7I85 for the PWM output, so you get a  buffered output
rather than a bare FPGA pin.

Reply to PCW with:
"Yes, that's correct:

7i85 encoder card on P1 (first DB25 expansion connector)
PWM on P3 (second DB25 expansion connector) for laser

Or if it's easier, PWM on P1 and 7i85 on P3 - whichever works best for the firmware. i use all 5 stepper outputs. so any port or pin you think is best will do.

Do you mean 7I85 on P1 and PWM on P3  (on 7I76EU P1 is the first parallel expansion connector and P3 is the second)

need firmware for mesa 7i76eu+7i85+pwm was created by advangrootel
Hi PCW,

I need custom firmware for 7i76EU with:
- 7i76 daughter card on internal SSerial (currently working)
- 7i85 encoder card on P2 (currently working)  
- PWM generator on P1 for 20kHz laser control



Can you create firmware combining all three?

Board IP: 192.168.1.121
5 axes: XYZAB vfd rs485 controls spindle direct on the mini pc with rs485 output

Thanks!
