Looking for Stepgen Index Homing Firmware for Mesa 7i76eu & 7i85S

Category: Driver Boards

Hi,
I was hoping someone might have a firmware file for a 7i76eu & 7i85S that enables the stepgen index homing.  Or if anyone has any links on how to make custom firmware I downloaded the source file and found a post with the necessary changes, but I'm not sure how to compile the firmware.

I didn't have enough encoder inputs so I only connected the index signals from my servo drives to the 7i85S encoder inputs.  Thanks in advance for the help.  

X-Axis ---> stepgen.00 --> hm2_7i76e.0.encoder.00.input-a
Y-Axis ---> stepgen.01 --> hm2_7i76e.0.encoder.00.input-b
Y2-Axis ---> stepgen.02 --> hm2_7i76e.0.encoder.00.input-index
Z-Axis ---> stepgen.03 --> hm2_7i76e.0.encoder.01.input-a
A-Axis ---> stepgen.04 --> hm2_7i76e.0.encoder.01.input-b
B-Axis ---> stepgen.05 --> hm2_7i76e.0.encoder.01.input-index
C-Axis ---> stepgen.06 --> hm2_7i76e.0.encoder.02.input-a

Hallo karle,

über die offiziellen Qellen von Denain 12, auf der die ISO von LinuxCNC 2.9.4 basiert, bekommt man nur ein solch ältere Version.

Die aktuellste Version bekommt man ein einfachsten als flatpak über den Flathub, siehe flatpak.org/setup/Debian

Viele Grüße

Michael

If you got to Mesa's web store and then to the specification tab for the 7I96S
there is a support software download selection. 

This support software includes firmware files for the 7I96S

Mesa 7i96s pkuart firmware

Category: Driver Boards

Hi,
I'm new to LinuxCNC. I tried to build a small milling machine and would like to control the VFD driver through Modbus.
I am using the Mesa 7i96s. I’ve seen some people mention flashing the card with "7i96sd_pktv2.bin" to remap the SSerial port to the PKUART port, but I can’t find this firmware.So, I’m stuck at the beginning…
Maybe I’m misunderstanding something?
Can you help me?Thanks!

Hilariously the XL is open source  github.com/FYSETC/Venture_XL
I am also curious tommylight , have you used other toolheads with the voron 2.4 like the DragonBurner or
RapidBurner? if so what is your opinion of them?

You might want to wait a bit till the hysteria settles down and the price will also settle down with it.
Or some China shop will come up with a much cheaper kit, as they did with Voron 0.1.
At the risk of repeating myself, if you have no parts for 3D printers already, it is much better to buy a kit than to source parts yourself, saves a lot of time and even more frustration. Also, after you finally source everything and build the damn thing, you have plenty of parts that don't fit that you payed for so the only reasonable thing is to buy more parts and build another one... :) That is how i ended up with 5 of Voron 2.4 !!!

Appreciated as always tommylight. I put the response there to show that there are kits now available
when before there were none.

Get rid of username/password?

Category: Basic Configuration

So far it hasn’t complained yet. :side:
Old HDD drives don’t like having their power cut off like that, but modern SSDs don’t really care.

 

If you're running an Rpi4 or 5 with a SD card this method has be known to corrupt the SD card. Ca n leave files open and prevents the OS from doing some "clean up" housework.

You can configure the desktop to start shutdown by pressing the ON\OFF switch on the PC or ask you if you want to shutdown, should be under Power Preferences.

I don't know if it's correct but I directly turn off the main power switch and everything goes off.

Debian tries to connect to the internet on EtherCAT network device?

Category: EtherCAT

That can't be right? Maybe it works, but you normally don't want nor need an IP-address on the ethercat interface.
Here is my config for I226-V in /etc/network/interfaces.
auto enp2s0
iface enp2s0 inet manual
        hardware-irq-coalesce-rx-usecs 0
        pre-up /sbin/ifconfig $IFACE up
        post-down /sbin/ifconfig $IFACE down
The i226 uses the Intel igc driver, the energy-efficient mode is off by default, so the igb.EEE=0 is not needed and also is for the igb driver, not the igc.
You can rename the nic with a .link file, google it the best tip there.

Debian tries to connect to the internet on EtherCAT network device?

Category: EtherCAT

iface eno1 inet dhcp
    hardware-irq-coalesce-rx-usecs 0

Ehm.... it worked! Thanks! The networkinterface for EtherCAT is no longer in the list of networks and now the internet connection defaults to the proper interface, and EtherCAT works like a charm now...but....why did that work? :-D I don't understand since nothing in that configuration seems indicate "oh, by the way, this will hide the interface from UI and prevent InternetConnection from trying to use it"...i've looked up the hardware-irq-coalesce-rx-usecs parameter and that only seems to be some sort of tuning, not something that should do what it just did....

Sorry, i'm just trying to understand it... the worst part is when something works, and i don't understand why it works ;-)

PS: I also disabled the power-stuff in GRUB as you suggested. Thanks!
