Re: [Emc-users] Installing From Debian?
And this install page has issues. https://linuxcnc.org/docs/stable/html/getting-started/getting-linuxcnc.html#_installing_on_raspbian_10 tells me the key is a new key but no user id. Continuing with the sudo apt-get update in the instructions tells me the signatures can't be verified because the NO_PUBKEY ... isn't available. And apt-key is deprecated. OTOH, no trouble installing the Arduino IDE. > -Original Message- > From: andy pugh [mailto:bodge...@gmail.com] > Sent: July 8, 2023 1:33 PM > To: Enhanced Machine Controller (EMC) > Subject: Re: [Emc-users] Installing From Debian? > > On Sat, 8 Jul 2023 at 21:31, John Dammeyer > wrote: > > > sudo apt-get install linuxcnc > > It reported an error > > E: Unable to locate package linuxcnc > > It's actually linuxcnc-uspace > > (Maybe it shouldn't be any more, but I guess we are stuck with that now) > > -- > atp > "A motorcycle is a bicycle with a pandemonium attachment and is > designed for the especial use of mechanical geniuses, daredevils and > lunatics." > � George Fitch, Atlanta Constitution Newspaper, 1912 > > > ___ > Emc-users mailing list > Emc-users@lists.sourceforge.net > https://lists.sourceforge.net/lists/listinfo/emc-users ___ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users

Re: [Emc-users] Installing From Debian?
Just did that.
I had earlier tried to move to bullseye - but a glade problem got in my way -
So just 2 days ago - I first upgraded from buster to bullseye - then bullseye to bookworm - installed linuxcnc from the
debian repository.
Good overview of upgrade at
https://www.debian.org/releases/bookworm/amd64/release-notes/ch-upgrading.en.html
Tells you how to clean out cruft before hand.
Only had a couple of minor problems - I had to reinstall a customized component - and fix a hal line that it didn't used
to complain about. There was a missing '(' in the old copy of hitcounter.py
What really made me smile is gladvcp just worked!
I run under kde - so I disabled the search indexing engine and other fluff.
You can run htop - before the desktop starts - go over all the tasks that you
probably don't want.
You can disable tasks with systemctl disable task-name
# cat /sys/module/apparmor/parameters/enabled Should return N if you get it
disabled -
You will want to disable apparmor.
You need to set a kernel paramater.. My line looked like this (a four core
machine)
GRUB_CMDLINE_LINUX_DEFAULT="quiet text isolcpus=2,3 apparmor=0"
isolcpus makes a difference as well.
This is with three copies of glxgears running:

Of course, latency is not so important is you are doing counting in hardware
(think Messa)..

Any one installed Debian 12 and running Linuxcnc on a machine? Since Linuxcnc
is now in Debian Stable, I was wondering if anyone cared to voice their
opinions about installing and running Linuxcnc that way.
I have a machine that I am starting to refit and I am considering trying to
install that way rather than using one of the more obsolete Linuxcnc ISOs.

Re: [Emc-users] [Emc-developers] Trajectory planner shortcomings
I did not do the G93 test myself but one of the other members did.

For example if your machine is configured for 100in/sec^2 acceleration and milling at 90inchs/min it would be able to maintain full speed through g-code with segments a little less than 0.01 inch long without any slow down due to single line look-ahead. Don't be confused by the huge slow down potentially caused by not using G93 (inverse time feeds) when you should be for mixed linear/angular commands. That slow down is caused by the F feed rate being applied in degrees/min limiting the moves speed (a 10 degree move at normal F90 will take 6.7 seconds.) A move will always be limited by which ever is slower the move's F speed in degrees/min or distance/min. If a combined move's degrees moved is greater than the linear distance moved, then the feed rate of the angular move will be controlling the time of the move. Switching from inches to mm in your G-code could also have a big effect, making the F settings 25.4 times larger, and therefore the angular moves 25.4 times faster. Todd Zuercher P.

What seems to be wrong with the trajectory planner when doing 4 or 5-axis? The trajectory planner only has one line look ahead for any rotary axis. So this means that trajectory planning is not really happening and performance is very poor when trying to achieve faster moves.

This means that a coordinated move that includes a rotary move will be dysfunctional at best. It's not as bad as that. There is a 9-axis blending planner in Tormach, but it's not trivial to merge it with Linuxcnc due to divergence in the codebase. If we could get hold of the patches that introduced it to Tormach then we could look at integrating it, but doing it just from comparing the code sounds hard. -- atp "A motorcycle is a bicycle with a pandemonium attachment and is designed for the especial use of mechanical geniuses, daredevils and lunatics." — George Fitch, Atlanta Constitution Newspaper, 1912 ___ Emc-users mailing list Emc-users@lists.sourceforge.net https://l/ ists.sourceforge.net%2Flists%2Flistinfo%2Femc-users=05%7C01%7C toddz%40pgrahamdunn.com%7Cab74bf847dbf4526bf1508db7ec2a17c%7C575854 4c573f47cebee96c3e0806fb43%7C0%7C0%7C638243146663401436%7CUnknown%7 CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLC JXVCI6Mn0%3D%7C3000%7C%7C%7C=TFj1jTETd5iX3h7J8%2B%2FNc3usPgZF o8N4E7lrAShUfhU%3D=0 ___ Emc-users mailing list Emc-users@lists.sourceforge.net https://li/ sts.sourceforge.net%2Flists%2Flistinfo%2Femc-users=05%7C01%7Cto ddz%40pgrahamdunn.com%7Cab74bf847dbf4526bf1508db7ec2a17c%7C5758544c5 73f47cebee96c3e0806fb43%7C0%7C0%7C638243146663401436%7CUnknown%7CTWF pbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI 6Mn0%3D%7C3000%7C%7C%7C=TFj1jTETd5iX3h7J8%2B%2FNc3usPgZFo8N4E7 lrAShUfhU%3D=0 ___ Emc-users mailing list Emc-users@lists.sourceforge.net https://lis/ ts.sourceforge.net%2Flists%2Flistinfo%2Femc-users=05%7C01%7Ctodd z%40pgrahamdunn.com%7Cab74bf847dbf4526bf1508db7ec2a17c%7C5758544c573f
