Sorry and ~/ means for xxx/home/linuxcnc or /linuxcnc ... because I install from package manager too .... 5 month ago ... than start now to check again my new project and not find that folders .... all linuxcnc is on ~/lib, ~/usr/share, ~/bin, ~/etc .... there are not folder named ~/linuxcnc .....

 

Try:

just checked on 2.9.2 installed through the package manager on a LMDE system , 'halcmd.h' is located in '~/linuxcnc/src/hal/utils'

see below

so try to install a new master .rip install .... but obtain these at the end.


Any how needs to install libreadline-dev

what is these??


regards

Hello,
Has there been any progress on the theme?

I found that the G64 will be slower than G61, twice or even more slower, in the stage of acceleration and deceleration.

Yes, I can understand that the overall speed will be slower, and he needs to reduce the speed to reduce excessive angle.
However, what I noticed was that his acceleration became slower.
Pay attention to it, weird things…, when use G61 or G61.1, I observe the servo waveform, accelerate the time meets the expectations, such as I can get the acceleration time curve of 100MS according to the acceleration I set over G61
But when I use G64, my acceleration time has slowed down, which is nearly twice the relationship, that is, I continue to observe the waveform and get a 200MS acceleration curve.

Regarding the formula for Theta(1,0):

I still don't fully understand the first formula, the short one at the top.
I think its calculating the "angle start" parameter for the z component.
 

This calculates the tangent angle (in the XZ plane) in the starting point (s0) of the clothoid on the first trajectory segment after rotating and translating the space corner so that the normal vector of the corner coincides with the z-axis (as shown in Fig 6 ).
If the corner is planar then the expression inside the bracket is zero and Theta(1,0) is zero (ie the tangent is horizontal).

I haven't yet been able to make up my mind if this method can also work for arc-helix corners.

[edit]
Well, I've given it a fair bit of thought and I cannot see a reason why it shouldn't work with helical segments.

The acceleration of X/Y I use, such as 500

SO search today with NEMO for example halcmd.h .... and find only "halcmd.1.gz" ..... from long time I use only rip installation than if work I install it .... so never investigate where that file is located in a normal installatio ... maibe there are not because it become .so or .a that system not copy these file in some locations ..... but I search for a confirmation ...

thanks

on the topic of my atc. seems a good reason to try and text the lichuan ethercat servos. 40mm 50 or 100w model.

Does ethercat works WITH the mesa card already there? as in, can i use both? or do i need to switch to all ethercat?

I had to get the wall mount version as I was squeezing it into an existing HMI enclosure that was too small to take one like yours. I looked back. 12 nobths ago, I paid USD $157 plus shipping to Australia so all up it was just under AUD $500



 

It'd be great if one day you could quote a post with a quote and not have the editor go haywire

That's exactly what mine "cost" but you got killed on shipping. I bought mine from the Chinese manufacturer on Alibaba. I'd probably do alot better if I ordered several

Hello
After a few hours I finally managed to install the iso on an old desktop.

I do have a question.
During the install there are options to install If I remember
the HTTP proxy

and mirror I skipped these 2 ...are these necessary and why?

if they are can I go back and fix it?

Also Is the user and password also necessary or about security when installing?

I am new at this and this is my first succesfull install.
Thank you!

The issue seems to be related to the file explorer within Linuxcnc.

Have you tried going up a directory, then going back into the directory you want ?

Having I guess, the file list for your wanted directory may sit in a cache and is not updated until you leave then re enter the directory ie: until the directory is reread.

I've also seem some strange behaviour from file managers within a program when directory is accessed via a UNC path or via gvfs rather than mounted into the file system ie: via fstab or a mount command.

I think windows shares may have setting that tells the system to mount them at login or not eg: automount or manual mount.
