More Decimal Places in the Default Axis GUI

Hello,

I would like to see a 5th decimal place in the AXIS gui. Is this a changeable setting? I looked around the LinuxCNC documentation and searched the forum, but I did not find any information about it.

Thanks

Not exactly, but because the relevant code runs in an interpreted rather than a compiled language it is relatively easy to change. Just be aware that you will need to change it again when you upgrade.

gksudo gedit (this opens gedit in super-user mode)
then open /usr/share/pyshared/rs274/glcanon.py
Edit line 1068 and change
format = "% 6s:% 9.3f"
to
format = "% 6s:% 9.6f"
for 6 digits of decimals/
Then save the file.

I can not guarantee that the line number is correct, this was a paste from an old email.

Will this mod give you that precision if you call for it? I have added gear reducers to the ball screw to add precision by 100. I would like to be able to call for it in g code instead of having to remember of dividing what i call for by 100.

Thanks for all your great posts.

If you have put in 100:1 reducers then you simply need to change the scaling numbers in the INI file by a factor of 100 too.

Im an idot when it comes to linux. Im loving i though if i only knew how to use command and knowwhat the hell im doin but i failed to edit the file

this is what i get
cyrut2@EMC:~$ gksudo gedit
glibtop: Non-standard uts for running kernel:
release 3.4-9-rtai-686-pae=3.4.0 gives version code 197632

cyrut2@EMC:~$ ^C

oKAY i got as fas as opening the file in the terminal but i cannot go to the section to edit the file. I tried it in the file manager but it says unable to open and write. Sorry for being such a noob but i cannot figure it out im reading linux for dummies and that is still over my head.

got a little farther but still denied..... ok so it seems i do not have a root user and password as it defaulted to the cyrut2 user that i created.... im reading on changing root to normal user but like i said this is new to me.


cyrut2@EMC:~$ su i
No passwd entry for user 'i'
cyrut2@EMC:~$ su cyrut2

seems that its manually installed so it didnt update im trying everything i can think off and still stuck...Help

You can try a plain "sude gedit" and if that doesn't work "sudo nano".

Nano is a text mode editor. It will take some getting used to, but at least the commands to use are at the bottom.
