Re: [Emc-users] Emc-users Digest, Vol 197, Issue 57
Chris, I am able to get the USB-ethernet adapter to work. However, I have to turn off the wifi and then unplug the USB cable and plug it back in. I suspect if I can disable the wifi (so it doesn’t boot with wifi enabled), it may actually but with the usb-ethernet adapter enabled.

Re: [Emc-users] USB-C to Ethernet dongle for RPi-4
First step is to verify that it shows up as a USB device. To list all USB devices, use the command "lsusb". If you don't see the dongle there, your problem is with USB, not networking.

[Emc-users] USB-C to Ethernet dongle for RPi-4
I am trying to figure out how to get my “Atolla” ethernet dongle to work with my RPi4. It doesn’t show with ifconfig. Can anyone shed any light on what I need to do to get it to work?

Since I play canary in coal mine, I run master, currently in the 2.9 territory, updated several times a week. On all 4 machines. And the tronxy I just bought, might even be run by linuxcnc, running on cura's output. It would be an interesting experiment. Marlin, for 3d printers, is not as configurable as I'd like. And since I have going on 2 decades with linuxcnc, I think I can use it to run a 3d printer. I have the 7i76e connected to the onboard ethernet and it is the only thing connect to it. I have the onboard wireless setup but I generally don’t use internet from the RPi4. I have a USB3 to Ethernet dongle. Maybe I need to disconnect the wireless and figure out how to enable internet through the dongle? That would be my choice. I'm using the 7i90-hd here, which is an spi interface. Using 3 of the 40 pins, it gets orders at 41 megabits in 32 bit chunks, and gets the 7i90's response in 32 bit chunks at 25 megabits. The 7i90-hd is pretty simple, with 72 i/o pins that can easily be configured for up to 4 axis. I blew 2 stepgens originally before I got the msg that I was supposed to buffer those 72 pins with a triplet of of 7i42TA's and installed those to buffer the outputs of the 7i90. Any way, the upshot is that I have good but pricey machine controls AND a full network thru the ethernet port at the same time. The 7i42TA also has std green screw terminals, much easier to wire than the 50 pin scsi connectors on the 7i90-hd. The pi3 was breathing pretty hard, but switching to a pi4 fixed that right up. While I was originally putzing with this, I bought a couple rock64's, v2's but lack of support at the time pushed me to the pi3b's, but I got booted from their forum for asking about a realtime kernel. They gave me a link, but then black holed me, so I've done all this by myself. And I've since put the rock64's to work driving 3d printers. Got a house full of those that claimed to be able to use PETG, but failed at the temps PETG needs. At the instant I am making the last 6 of 9 big vise's for woodworking workbenches. Truely big vises use wooden screws but no one has made any new ones in around 100 years, so I've designed in OpenSCAD a new screw, 20+ inches long, 2" in diameter with a 12mm pitch, 2mm buttress tooth 6mm long, 5mm tall, in two start style, making the screw from hard maple on my 4 axis 6040 mill, and printing all the plastic nuts, holders and housings from PETG or 20% carbon fiber PETG. But I need a bigger printer for the nut housings as my ender 5 plus failed the long term PETG challenge so a 400x400x400 mm Tronxy-400 is due here today. And I already have a hot end for it that is supposedly good to 300C, PETG needs 240-260 heat. The little printer, a Prusa MK3S+, I was able to source parts for it that are taking the heat, but it can only do one half of the outer housing in about 2 days at a time. Hence the houseful of failed printers. The outer housing is part of my design to tolerate a miss-aligned screw, its partially self aligning. This is for a paddle vise, which is a 2x8 leg with a pin-able stick at the bottom, where the pin is moved from hole to hole in order to adjust the top of the 2x8 carrying vises jaw, to be parallel with the stationary jaw regardless of the thickness of the work piece its clamping. So I'm having fun keeping my self out of the bars till I miss roll call some morning. I'll be 88 next week.
