Hi,

Today i was creating the G5 for spline.

Here it tells us to use incremental offset's for i,j in g17 plane. It seems to lcnc uses a 2d spline.
g5 linuxcnc

Then i thought why not use absolute point values for a spline?
Here is my proposal to use a spline in gcode.

It start with a G5. Then every line has a x,y,z point, until another gcode appears.

And the result :

  So far I am thinking I may set the lathe up more like a 2 axis with the spindle as a rotary indexer to escape
the multiple axis problem. That does require a rethink for setting up the part model of instead of a cylindrical part
to a 3D flat part and cut the model out in multiple longitudinal slices.

  in any case the G-code will require splicing to bring it all together.

Can you run this command:

sudo chrt 99 ping -i .001 -q 10.10.10.10
 hit control C
then run it again
sudo chrt 99 ping -i .001 -q 10.10.10.10
wait about a minute and hit control C again
 and copy paste the result here
(Those commands assume you have the 7I92T IP address set for
10.10.10.10,  if not, use 192.168.1.121 in the ping commands)

Also run
lshw -class network
to determine what Ethernet hardware you have
 

I'm experiencing the following on a fresh install of LinuxCNC from the iso (2.9.3):

this happens intermittently, but typically within a few seconds of jogging the machine around after enabling it. No motors are hooked up nor anything attached to the 7i92T other than +5V power. If I enable the machine but don't move any axes it will eventually happen after some number of minutes. I'm using a generic mini PC and have tried two identical PCs with a fresh LinuxCNC install and have the same problem on each. I've also switched ethernet cords with the same result.

I've read through this thread forum.linuxcnc.org/27-driver-boards/4691...error-finishing-read and nothing really conclusive came out of it. I do also get a real time error on LinuxCNC startup or shortly after, but doing latency tests in pncconf shows fairly good numbers. I don't have the specifics in front of me but I can get them.

 I have not tried switching the +5V supply but that is my next step.

Any thoughts on how I can further diagnose this?

Thanks!

Have the same issue converting my config files from 2.8 to a 2.9 install.
I was guessing it might be from differences in the tool change files? But I can't really check about it -.-

If doing the same thing now, I think that I would bas it around external_offsets, not kinematics.

Taking a look inside external_offsets, i too think that i could be a better solution, but i'm now wandering if i can somehow program an external_offsets matrix that corresponds to the way's warpage like the correction .STL of ProbeKins

This pretty much says it all. I just wish it had the animation.

That is a bit to old, but should be usable, so if you can install Debian BookWorm, open a terminal:
sudo apt update
sudo apt upgrade
sudo apt install linuxcnc-uspace
That will install everything needed.

Regarding search engines, use google and duckduckgo, google could not find an stl using the exact file name, duck showed it as the first result. For some stuff it is the other way round.
In general, all are useless.

ouch, that's quite a price tag rodw.

on another front I just found this for FreeCAD.

Note that spindles can be run from PWM or step/dir outputs
in addition to analog outputs
