What you need to do depends entirely on your interface hardware.

What interface hardware do you have?

If this is for a parallel port interface with the particular breakout card pictured,
you would use stepconf  to add a spindle PWM generator to pin 1 for the spindle
analog speed control, and perhaps use the breakout cards relay output for spindle
enable (pin 17)

"Yes the RPi5 requires an external PSU (does that really need to be mentioned ?) but some mini PC's require an external as well. Lenovo is one brand that comes to mind, I think the power blocks are similar to the Laptop power blocks."

Yep, I have at least 5 or 6 different MiniPCs around here for LinuxCNC testing and general use and none are
line operated, they all have laptop like power dongles (either 12 or 19.5V)

The extra money would only be spent & wasted. (VB\Jack Daniels doesn't agree with my head, women are way too much hassle and I'm way way too decrepit for the the Circle Pit or Wall of Death nowadays ).

Must try to remember I'm not 18 anymore.

Interesting conversion synching to an analog signal have never done that. Very nice build. I've attached a picture of my monster build 4' x 4' 6 inch Z.

the docs are actually for the develop version, so just use the docs and configuration page information for any changes required

As an addendum to the above post, I'm working on a new Raspberry Pi image, suitable for both the 4 & 5 based on the raspios, that has all the nice setup features of a standard raspios image.

I'm hoping to create both a Bookworm & Trixie image.

That is horribly bad advice. When using the GPIO pins on an RPi you require a base & servo thread, as you would with a PC with a Parallel port. Using a Mesa Ethernet card, in the case of OP, or a Mesa SPI card you only require a servo thread.
I use a RPi5 with a Mesa 7i92 & 7i76(plus some other smart serial cards) and I am very happy with it.

Thin Clients may also be an option HP T630 are not so expensive on the second hand market and have a Quad core CPU,

Hello for all!

I'm want to control my spindle with LinuxCNC but I have no idea how to do this. I have a 2.2KW YL620-A VFD and I found in the manual some instructions for wiring and configurations for the VFD but I have no idea what to do in LinuxCNC. I attached an image with the wiring.

Thank you!

 

The standard instructions are for stable releases.    Monokrom is still in development.  To enable access to development you need to adjust the sources line in /etc/apt/sources.list.d/kcjengr.list to read:deb [arch=arm64] repository.qtpyvcp.com/apt develop main

NOTE:  the arch= on your install migh be different.  Do no change that part of the entry.

Cheers.
 

I would not recommend the PI4 unless you already have it. It's a bit slow and requires
fussing to get a 1 KHz servo thread over Ethernet. The PI5 is much more capable.

 MiniPCs are normally fine though if they have RealTek Ethernet hardware you will likely
need the DKMS (manufacturers) driver as the built in kernel driver has latency issues.

A Raspberry Pi has its own I/O pins (albeit limited to 3.3V); connection via ethernet seems a bit of a waste of the Pi's functionality, at least so far as I/O is concerned.

Is the ethernet NIC in the Raspberry Pi as good as a PC motherboard's NIC?

Mini PCs can be a bit annoying to to the space constraints.

Keep in mind that while PC can run off of AC line voltage, a Pi needs a separate power supply.

If your PC power supply is good, you can siphon off power for other stuff, though there is some risk involved with doing so.

"spindle.0.on" muss auf einem pin liegen (z.b. relais), dann erscheint die auch im axis gui

Guys, I'd like to hear your opinions.

I have a 7i92H and would like to build something very compact with reasonable performance. What do you recommend using, a Raspberry Pi4, Pi5, or even a mini PC?

Im setting up my cnc which has a toolchanger but i have some weird issues that if the tool prepared and tool changed iocontrol hal pins goes high i get an error that line 0 would exeed the z axis / joint 2 limit. I have 2 machines running linuxcnc but still cannot seem to figure out the problem. Im very lost so any info would help.

this sub is just as a test.   

As far as I know , only quadratic encoders are currently supported with remora and rt1052

I'm not sure about the ec300 but the ec500 has the ability for hardware counting but you have to bypass the optocouplers as they are shite.
