just use the one here github.com/scottalford75/Remora-NVEM/tree/main/Firmware
use only the files in that repo for linuxcnc installation as well, the remora-nv one
everything in the videos about this stm board will still be relevant im sure


these stm ethernet boards have more users than i would have guessed

Hi, I am new to LinuxCNC and have some questions about how LinuxCNC find the RT CPU (isolate CPU core) on PREEMPT_RT.
It seems the find_rt_cpu_number() function in uspace_rtapi_app.cc either choose the environment variable RTAPI_CPU_NUMBER (which is NULL if not set manually) or choose the last CPU core regardless of whether there is an isolated core.
e.g. The isolate core on my Preempt_RT is core 1, but find_rt_cpu_number() returns 3 and the RT thread is running on core3 in the attached images.

My test version is LINUXCNC - 2.10.0~pre0. Thx for your time :-D

 

Thank you. I noticed that a few minutes ago.

There are some variables to enable hole mode etc in the top of the plasmac post processor in sheetcam. They may help

Is there another way to upgrade to version 2.10?

This is a bit tricky if you are using the 2.9 download. the official Linuxcnc repo does not contain 2.10
You would need to edit linuxcnc-uspace.list in one of the /etc/apt folders to use the buildbot2 settings described here
buildbot2.highlab.com/

Otherwise download a deb file from there and install it.
 

Assuming you are using the linuxcnc rpi 4 image, on the command line, try typing menu-config and selecting the correct locale for your part of the world

First attempt at physically fitting everything together.


Need to work on the 24V and 5V power supply mounting.

I really didn't like the last one so I tried something different and this is the result.
You don't need user_live_update, just use the below in bigfileopen.tcl. 

I believe so. 

is it for sure an STM32 board?

Hello Tom,

Maslow advertizes CNC'ing of wood sheets and that's what I need to do so let me see how far I can go with it and LinuxCNC. BTW Maslow goes at about 1 inch per second so there are no kinematics.

I'll start by locating the LinuxCNC documentation starting point(s).

Thanks Tom for the input,
Tom

Hello @cornholio,

You are right - I need to move on to LinuxCNC. I noticed a new CNC machine. It's called "Maslow". Google it as "Maslow CNC".

I want to use it for cutting out frame members for wooden boats.

Does LinuxCNC support it or does something need to be done?

Hi,
My local makerspace has a pair of donated Journeyman 325s. I am retrofitting one with LinuxCNC. We have a small form factor PC that should work with a 7I97T I purchased a while back.
My plan is to leave the wiring alone as much as possible. Using 3 DB37 breakouts and a DB15 breakout. Later I will use more of the existing wiring to wire front panel switches.
The number of IOs seems very limited with only 5 relay outputs and maybe 10 inputs. The input wiring is not very clear in the machine drawings so I will have to trace them out for verification.

I have two different wiring diagrams if anyone needs them.

Linked is a Google Sheet with wiring notes.

My RPi5 kit has come up. A book report:

The full kit name as listed in Amazon is:

  -- iUniker - Extreme Starter Kit for Raspberry Pi 5 - (8GB RAM - 128GB Storage Edition)
  
Definitely a learning experience (several delicate operations but that's probably good if you are needing to learn).

• A critical concern with all electronics not designed to handle it is electrostatic discharge (ESD). Shuffle across a rug and touch the bare board and your new RPi5 may never come up. The RPi5 specs make a nod toward ESD protection but one way to get by ESD, if you don't have a special "static discharge mat", is to lay down a very slightly damp cloth and work on it.
•  I only received a 64 GB SD card instead of a 128 GB SD Card.
•  I only received one video cable instead of 2.
•  Once installed, the fan connector needs to be inserted into a plug on the board. The plug seemed to elude me for quite a while but it's there. Be very sure of which way around the plug needs to be oriented.
• The 4 USB connectors are very, very difficult to insert into. I worried about the stress on the board. I opted for a hard-wired keyboard/mouse combo and had to use 2 USB connectors. It supports wireless keyboard/mouse combos if you have them in pairing mode at system boot time.

Finally, it came up, started, and took my breath away. Very cool.

At the risk of repeating myself, Tom, thank you for being hell bent on helping this project.
BTW, my name is also Tom.
Reading your posts i am baffled at where did/do you get the info, as
-LinuxCNC project has always provided a ready made image, since the time of "Brain Dead Install" (that was the name), and Ubuntu 6.04, 8.04, 10.04, then switched to Debian as Ubuntu started causing issues with logos and trade marks
-From 8.04 and up till now, all those images can be used in Live mode, without installing anything, and YES they can run the actual machines in Live mode
-Installing those images is as easy as any other Linux distro, no knowledge or sysgen required
-Included wizards are easy to use for anyone with a faint idea of CNC workings or a bit of reading, took me 2 minutes flat to have the machine working the first time i used it with Ubuntu 8.04 i think, over 15 years ago, but i have extensive electronics experience so i do not count
-Maslow should not be an example of simple CNC as it uses ropes to move, making it limited in many ways and hard for humans to figure kinematics, any XYZ hobby machine is simpler to understand
-
And in general, nothing is easy when dealing with a 15 ton machine with electronics, hydraulics, pneumatic, vacuum tool changers, pallet changers, and multiple safety trips to prevent from making minced meat out of humans...
Yet, LinuxCNC makes that possible for plenty of inexperienced users with a bit of time and effort, just have a look in the "show your stuff" section.
