Update :

I believe my stlink stopped working fine. I've used nanoDaplink and there was still no answer from the nvem. Finally I've pushed (and keep it pressed) reset button on nvem, then start flashing with pyocd. When I started pyocd I've released reset button and whole process went fine from there. It was flashed with remora 3.1.3. Later I've connected ethernet and tried to ping. One of the leds on nvem went off and my ping was succefull. Then I've used this config :

github.com/scottalford75/Remora-RT1052-c...NC%2Fnvem-rt1052.txt

And it was all good. Previously I've used by mistake basic and full config from here :

github.com/scottalford75/Remora-NVEM/blo...vem-basic-config.txt

Which I believe was not for RT1052 version of nvem board. DON'T USE THIS CONFIG. 


Quick install eth component and everything works perfectly. I can move 3 connected axis with this linuxcnc config :

github.com/scottalford75/Remora-RT1052-c...Fremora-rt1052-basic

But this Linux cnc config is only for 3 axes. Do I have to manually set my 4th axis? 

Next step will be adding limit switches, one for each axis (except 4th). Maybe this evening I will find some time. 

 

Hi Arciera,


Is this all happening in user-space so far (including the velocity planning)? If so does this output a GCODE file?
Yes, this is all done on a non realtime kernel at the moment. Including the velocity planning indeed.

Currently i have no logic to output a optimized gcode file, but it is certainly possible.
How relevant is this option at the moment?
We could also add a scurve path simulator to the user side.

Then the kernel motion code, can be centralized in a c++ class, then both the user side and kernel side can use
this code to run the program. This is just an idea.

This file has ~12500 lines of gcode.Used G64 P0.5 Q0.5
red=3d velocity profile
white=line
purple=clothoid fillet
cyan=spline fillet

 

It's now almost time to test the results on a realtime kernel.
Let's work on to that.

For a letter test:
Original input G64 P0 Q0.5
 
Input G64 P5 Q0.5
The spikes from the velocity profile are gone !

1. Mesa must be wired directly to PC
2. set up the networking using network-manager:

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?
