So it happened again this afternoon on the Pi4 1GB. Wifi is active as is
Ethernet to the 7i92H.

Well, the existing preemp-rt kernel when I built the 2.8 release
packages was 32-bit,

Nah, we just get trolls on the list from time to time. They don't have
any solutions, just random complaints and half baked ideas.
Well, I've been reading everyone and I guess I'll stay with the normal PC

Well, I've been reading everyone and I guess I'll stay with the normal PC
architecture for now. I'm not doubting about the capabilities of the Rpi
but really don't have that much time to play around with it.

Lol openbuilds is using grbl because it’s simple. Openbuilds doesn’t specialize
with larger and more complex machines along with more sophisticated control
systems and user interfaces. Grbl is great for simple router machines and
openbuild’s “MiniMill”. It’s a toy for larger and more complex

Don't want to fuel any flame wars, but this kind of solution is probably fine
for generic desktop cnc routers with steppers. Grbl even has jerk limited
trajectories. As soon as you get out of that stock 3 or 4 axis space and want
to have tool changers, servos, non-cartesian machines, lathes,
Sorry to say, but here you missed something. A motion-controller is needed in
addition. They mention something like grbl 1.1, ….
LCNC is all that together and can do a lot more. This seams to be some fancy
pendent for grbl.
just my 2 cts.

My point was you could free up the Raspberry Pi, you don't need it if the
printer is within a cable length of anything that already runs LinuxCNC.
Then you are a "free" Pi to experiment with

It does take a bit more fiddling to get everything going on the Rpi 4B, but it
seems to run pretty nicely once done. I don't have experience using it with a
7i76e, as most of us use it with the $45 7i90. If you don't need hardwired
ethernet for communication with the 4B, then you can
I'm running a 4gb pi4b on my Emco lathe with minimal issue. My pulses per
unit are really high because of the screw pitch and belt reduction from the
emco factory, but it still seems to get along nicely with the rest of the
machine.

Check out my LinuxCNC tutorials,
I have been happy with it.
Not been using the PI for production - mostly just tinkering.Doing some
pretty complicated configs.
I have had it up for many days at a time with no issues... Running
programs that run hours...

I wouldn’t expect the 3B to work with Mesa Ethernet as the pre-4 Pis have the
Ethernet in the USB bus.

Well, the portability is not a must, but the idea of having all the major
hardware as compact as possible really tempts me to at least consider the
idea. For the other machines I used mini ATX with one PCI express port to
accommodate the Mesa board. For this project I'm inclined to use an
Ethernet
Why does the control computer need to be portable, unless you are building
a portable router and want the whole machine to be easy to move?
As for Octoprint, I use a standard PC (an older i5 with about 8 GB RAM.) f
In fact, the very same PC runs both LinuxCNC and Octoprint at the same
time just
I have several RPI3's and RPI4's. what I noticed (with the RPI4) more
memory is always better.
There are things they are good at, especially "light-weight" stuff, and
other things they are not. I use one as a datalogger, I tried RPI3
RPI4-1GB/4GB/8GB, and it has timing and temperature
Hello guys,
As some of you know, I'm finishing a CNC router and I'm about to purchase
all the control hardware. I know Gene, John, and several people here are
running LCNC on the PI with success but I would like to know how much of a
pain in the ass is to get it running well with a 7i76E for
27 matches
