Hi guys
I am currently deciding what to use to connect my front operator panel to
the control box in the back of the machine.
Here are the options I know about. Feel free to let me know of a better

Hi guys
I am setting up a VMC with a mesa 5i25 and 7i76 combo
I am struggling with pncconf because I can't find any up to date tutorials
on it. Everything I can find is all out of date from 2015. Anyway does
anyone know of any good tutorials I can learn or the best way to go forward
from here.
Hi guys
I am currently running 2.7 linuxcnc. I think it is the stretch iso but I
am not sure. how to I tell if I have linuxcnc stretch iso. would love it
if someone could show me a simple way to tell what i have. there must be
some show command.
I just wondered what is involved in changing

Hey guys.
I just got my cnc mill moving now but I have a couple of questions about
step timings.
My servo drives and Linuxcnc step setup are set to move 0.001 mm per
pulse. And I want to move at a max table speed of 12000mm/min. So that is
a max pulse of 12,000,000 pulses per min or 200,000
Just a update. I got the mill moving! Not too sure what the problem was
but it's going now.
And I posted another question on a stepgen PID issue.

Hey guys.
I will post this on the forum also...
So I'm just setting up my cnc mill with Mesa cards and step/dir
Using 5i25 and 7i76.
Chinese servos are working well.
But I just spent most of my Saturday chasing this funny stepgen joint error.

Hey guys.
I saw that some guys are using laptops with linuxcnc. I only want them for
testing. Just wondering what laptops are good and any tricks to set it
up. I'm using Mesa pci cards so that might be a problem with a laptop.
But any ideas would be appreciated.

Hi guys
I was just wondering who here has retrofitted any big commercial machines
with linuxcnc and who actually uses there machine to make parts everyday.
I work in machine shops and am using fagor/ siemens/ controllers all the
time. and I am retrofitting a cnc mill myself as a project and so
it. If people send their videos in they should be
added to the linuxcnc showcase
