G93 problem with speed

I think that the explanation for this misunderstanding is that I am an idiot.

In the part of my previous post I was trying to point out that problem I am facing cannot be solved by splitting moves in two moves as this does not change feed rate (speed) of the move, and this (speed) is what is actually limited by hard coded 0,1.

Yes, looking at the code properly, the output of the max() function is the final feedrate, not the F-number.

There is a fix on the way: github.com/robEllenberg/linuxcnc-mirror/...93-minimum-feed-rate

I am running rather old version of linuxcnc because I am running an old computer.

I have linuxcnc 2.5.0 on Ubuntu. And tried live CD with new system but it did not work.

Will I be able to somehow install new linuxcnc on my system?

That depends on which Ubuntu you are using.
The LinuxCNC support matrix is here:
wiki.linuxcnc.org/cgi-bin/wiki.pl?MinimumSoftwareVersions
LinuxCNC 2.8 is supported on Ubuntu 12.04 Precise, but not 10.04 Lucid.
(Lucid is 10+ years old...)

I had a look at the link you provided.
But with no linux experience at all I am not able to understand this table.

How can I find out which ubuntu I have?

Cris.

Try the command

lsb_release -a

Ok it says:
Description: Ubuntu 10.04.4 LTS
Release: 10.04
Codename: lucid

So what would be my options for upgrade?

You should be able to run 2.7.14.

linuxcnc.org/docs/2.7/html/getting-start...dating-linuxcnc.html

I am currently running linuxcnc 2,5

Should I update to 2.7?

Cris,

You should, there are some major changes to trajectory planner in 2.7.
