Re: [Emc-users] Making ApplePi

[John Dammeyer]

1. Yes.  Has both WiFi and Ethernet port which is why I considered this for the 
Pi OS.
2. Doesn't run from the USB.  It installed from the ISO image written to the 
USB.  And then became from the outside view a Pi4.

3. I want to keep it looking like a Pi4 like the one sitting by the mouse pad 
in the picture which does connect to the 7i92H and a couple of BoBs.

So what I want it the Pi OS that also runs LinuxCNC.  I don't want LinuxCNC on 
the MacBook Pro.   If that makes sense.

Re: [Emc-users] Making ApplePi

[Chris Albertson]

The Mac has an Ethernet port, does it not?  You say it is an older Mac, so
it likely does have one.Some of the newer Macs lack the port, and you
have to buy a USB-C to Ethernet dongle.

If it has the built-in RJ45 jack simply connect it. If not buy the Dongle
on Amazon.

At some point, you will want to install Linux on the Mac.  Running from the
USB drive is very slow.

It is odd to say the Mac acts like a Raspberry Pi.   No. Any computer boots
to Linux looks like a Linux PC

[Emc-users] Making ApplePi

[John Dammeyer]

I used my wife's old laptop now no longer supported by Apple. Even the battery 
needs to be replaced again if I can find one.  It's essentially trash.
 
Unless I make ApplePi.  Insert USB stick with the ISO.  Answer questions etc. 
And then reboot into Raspian looking just like a Pi.
 
Now the question.  How would one go about adding LinuxCNC connected to a 7i92H

Content-Type: text/plain;   charset=utf-8

Hi,

I am looking for a viable alternative to the Raspberry Pi. I need this to fit 
inside a pretty small enclosure, so I can?t accommodate a much larger size than 
the Pi.

Has anyone tried the Intel NUK products?


Thaddeus - I use them all the time; I have about 150 of them (with large 
touchscreens) deployed in place of ipads for public kiosks.


I also use them for LCNC; their best features are typically removable 
PCIe wireless cards and real SATA interfaces. I stay with wired network 
(machine LAN such as MESA cards are on the native eth port) and comms 
LAN (internet, data servers, etc are on a USB-ETH  adapter). The 
wireless chipset is random based on the platform, and sometime drivers 
don't work.


The biggest problems I've had is that if it was prior-installed with a 
WIN environment, wiping the drive and simply installing LCNC from usb 
will not yield all the USB ports active - so you have to go hunting 
through the BIOS to manually enable those. It is quite happy in UEFI 
mode or legacy mode, your choice.


I *prefer* to stick with the core i7 units, but I do have a couple of i5 
and (Beelink? amd and rockchip) units also doing the same, just with a 
slightly lower response.  Servo performance is quite acceptable, jitter 
is all over the map, so of course testing in your use case is warranted. 
I also stay clear of any that have dual HDMI ports - they seem to fail 
at the hardware level more often (irregardless of the OS that's running 
on them.) I don't use them for software stepping, so cannot speak on 
that particular topic.


Worst part is dealing with the 19v power supply - they are often 
intolerant of anything but their own power bricks.


Ted.

Re: [Emc-users] Linuxcnc configurations using Mesa

[Martin Dobbins]

Hi Alan,

Perhaps this holds the answer:

Martin

From: Alan Condit

Thank you Peter and John,

I changed the thread timing, and added the isolcpus=1,2,3. I haven’t added the  
force_turbo=1 in config.txt yet but already it is much improved. I haven’t run 
it long enough to get it hot, I suspect I need a fan on it when I add the 
force-turbo=1. It is in a Raspberry Pi4 case with no fan.
