For what?
What reduction?
Mesa and RPI are OK, the questions are regarding G540.

Hei thank you for reply.
First if all sorry that my post was simple. So I will expand my post with some extra words. :)

I have a machine that I builded for 10 years ago and was always running machine with a regular pc that has some form for linuxcnc.
At the moment latency is a issue and I decided to change system. I still use the same g540 :) the thing just unbreakable.

Issue so far is that I never used a raspberry pi before. And i am struggling now to instal a version that will work. i tried so far with official Linuxcnc system image for raspberry pi and stoped right at the boot. Some error about old operating system. I saw it was discussed in some thread.

I tried other way. Installed raspberry os and there got error apt-get not allowed anymore. :) do you guys have a link where I can find instructions how to instal linuxcnc on raspberry pi 4 (8 gb).

Little bit about my machine.
It is small but capable of machining softer metals like alu.
Dual x axis and z axis 3a motor
Y axis 3,5a motor
24v power supply
Wj220 vfd running 1,5kw spindle
G540 controls everything.

Why not use the PC you have? I have one machine that uses Ubuntu 10.04 with Mesa 5i20 and some version of EMC.

With the 7i92T you will need Linuxcnc 2.9 if I recall correctly.

Hei
Thanks for reply and input.
The reason is simple I have a raspberry pi and a touch screen and it is tempting a option that has small footprint. It just sounds so rlegant to have a small box with touch screen to control my machine.

I didnt buy any mesa card yet but i am exploring different options. My current setup is still ok and working but i need to change something soon. Last pc I had was so bad that on the end my motors was blocked in the middle of operation.
I guess running thru parallel port is not option for the future.

My personal problem is that i am more of mechanical guy and each time i need to do something with system i forget what i did :) and need to kind of learn things again ;)
But there is usually a lot information on this forum and community is very helpful and active. At the momet i am learning about ppf setup and mesa cards.

Grateful for answers here.
