LinuxCNC (For lathe) install on Rapberry PI4 - Nov, 2024

Category: Installing LinuxCNC

I see there are previous threads about this, but things change with time and releases, so better to ask then chase my tail.

I previously setup LinuxCNC - Axis on a desktop PC for my mill, works great now I want to do the same for my lathe using a RaspberryPi4 Model B (4GB RAM, 32GB SD)

How do I go about this?  Some form of instructions would be very helpful.
Link to whatever version I should use?
Does the install prompt what type of machine this will be used (Mill, lathe etc)?
I ordered a A MESA 7i96S, not sure when it will get here.

Any helpful hints are welcome.

Thanks in advance.

Issue with Attaching BME280 Sensor to Raspberry Pi 4B on LinuxCNC

Category: General LinuxCNC Questions

Hello #MyFirstPostHere,I am trying to attach a BME280 sensor to a Raspberry Pi 4B to monitor environmental variables (temperature, pressure, and humidity). The sensor is connected to the 3.3V, GND, GPIO2, and GPIO3 pins. It works flawlessly when running Raspbian OS (64-bit), and I can retrieve readings via the terminal.However, when trying to use it with LinuxCNC, I encountered multiple errors.Upon checking the I2C buses with the command
ls /dev/i2c-*
, I found
/dev/i2c-20
and
/dev/i2c-21
, but I was expecting
/dev/i2c-1
, as seen in Raspbian OS.I was wondering if there is a solution for this? Is it possible to get this sensor working on LinuxCNC?Please feel free to ask for any additional information.
