Hi Tim

I am having the same issue. Have you figured this one out?

I've done this before on another computer and there was no problem. Is there a problem with the computer?

Start with the kernel packages, then I think there are some modules then finally the Linuxcnc packages. Best thing is to read completely read through both threads linked in the previous threads.

Looks _very_ good!
Is this all happening in user-space so far (including the velocity planning)? If so does this output a GCODE file?

As far as I understand, I have already downloaded the files but what commands should I use to install?

Hi,

I fixed some issue's in the gcode parser, it now loads the lcevette lift_test.ngc file ok.

In gcode we used:G64 P0.05 Q0.05

It filters out tiny lines according Q value.
It add's fillets according the P value. It first try's to add clothoid fillets, then it add's spline fillets.

There is a lot happening performing the algo. Fillets can be made between 2 helixes for example.
Every scenario had to be code.
Overall this is quite a complex task.

Colors to verify:
red=3d velocity profile.
white=linelight_green=arc
purple=clothoid fillet
cyan=spline fillet
yellow=trimmed helix
dark_green=helix
 
 
 

When G64 P0.0 Q0.0 output:
 
 

Good morning, I don't know if I should make a new topic, but I discovered from the worker with the machine that just opening Linuxcnc with feed and rapid at zero doesn't completely solve my problem, when I open Linuxcnc it opens at zero as expected, but it works only for the first piece of the day, because then I adjust the feed override and rapid override as I work, when I load a new file without closing Linuxcnc and run gcode, the feed and rapid override are in the last position I placed, I wanted to know How can I make it read when I open a new gcode it resets the feed and the fast again? I don't know much about Python, but I believe it is possible to check LinuxCNC's status to perform zeroing in Python. Could you give me a tip on how I can write this? I'm kinda lost

Hello everyone!
I intend to learn how to use LinuxCNC and I immediately saw an ISO 2.92 RT.
However, I use LPT and a PCI Express. What I need is a step-by-step guide to installing RTAI with the newest ISO possible or if this ISO can be configured. I don't really know anything about Linux, but in tests with the pendrive simulator I saw that the machine ran much better than Mach3 even though it wasn't RTAI.
I'm counting on my friends' help.

You need to set up the driver manually. If there is software for the driver it is a very easy task. Automatic settings have never worked well for me.
A minimum error of 1 is too large for most machines.

Unfortunately there isn't software available for automatic tuning of CTB servo drives So it has to be done manually...

I can't seem to get rid of the delay between commanded position and actual position... this does not seem to be a property of PID-tuning... is this a EtherCAT thing or something else?

You say that 1 is to large for most machines... what is a good goal to have? What are the units of this? Is it milimeters of error between commanded and actual position, if the machine is metric? Or what does these two properties represent?

Hello,
I have servo drive from Tsino-Dynatron which has strange design:
- One Drive has built-in 2 Slaves
- One Slave has 3 modules which drive 3 motors
I attach file of esi from manufacturer and export from "ethercat xml" command.

I did xml too, but do not know how to command to motor-2 and motor-3 of slave-1
I checked lcec_conf data type, there is no "module" or "device" type, so how to address module-2, module-3 ?

Any idea ? Thank you.
 
 
 

If I were to try and do something like this I would get a few RPis with Linuxcnc running on each of them and figure out a way to feed them with gcode from a master PC. The synchronization would be through hardware IO shared between the individual installations.
[edit]
This really seems the most sensible way of doing this as you really just have a number of machines running in parallel without the problem of one interfering in the space of the other. Each station runs it's own Gcode and simply waits for the signal to start. Once it is done it sets a hardware output so the master installation knows when to rotate the carousel. This would also eliminate the need for fancy CAM solutions to generate multi channel gcode and you would have total freedom in the design of the individual stations.

I copied this from a previous question that seems similar....does the partial answer i pasted below seem appropriate for my desired use?...

Using additional axis letters will only let you run different tool paths by running them sequentially (ie you would have to wait for one to finish until you could start the other). If that is all you need then it may do what you want but that is not multi-channel use.
Multi-channel controllers can run different toolpaths in parallel, basically like running two machines at the same time with the added benefit of being able to synchronize the two to avoid conflicts.

An extra joint is just a single 'axis' .

LinuxCNC can handle 16 joints in total (any combination of XYZABCUVW plus 'extra joints')
So if you need XYZA for your coordinated station then you have 16-4=12 extra joints left.
If your coordinated station needs a tandem axis (eg for a gantry) then you have 16-4-1=11 extra joints left.
Extra joints can have a homing procedure, min / max limits, max velocity and max acceleration values.
Extra joints can be moved by setting the 'in' pin of the assigned 'limit3' hal component, this can also be done from GCode using a custom Mcode.

I'm afraid I don't know what would be needed to add multi-channel capability to LinuxCNC but I'm sure there aren't many people who know the code base well enough to even think of taking on such a challenge.
