That is a common issue with the latest RTAI kernel/LinuxCNC that was fixed to a certain point.

 

OK, I'll install it and see how it behaves

Well, I made a configuration with just the 3 axes and it opens linuxcnc, however if I configure spindle I get this message and it also restarts the login, and sometimes the screen locks and I need to reset the PC

All my "Mach3 Cloned Wizards" for lathe (NGCGUI routines)

Category: Lathe Library

Hi!

These are probably all my lathe NGCGUI routines. I have been making them for several years now. Everytime I need a new one I find some time to code it down.

I tried to keep them as close as Mach3 Wizards as I could. I even edited the images to look similar.

They were running just fine in my latest retrofit.

I hope it helps someone.

Data transfer LinuxCNC to / from custom board - Solved

Category: Advanced Configuration

Note that 'halui.axis.jog-speed' needs to be set for plus minus jogging:  linuxcnc.org/docs/html/man/man1/halui.1.html

Thanks for that, however setting halui.axis.x.plus did not help.
When I press the Arduino button, the jog-x-pos and the halui.axis.x.plus indicators both change from yellow to red. For some reason they don't trigger an actual jog.

hm2/hm2_7i96s.0: watchdog has bit! (set the .has-bit pin to false to resume)

Category: Installing LinuxCNC

We asked for return of the card to eliminate it as a possible cause of your issues.
We do ask for shipping for cards returned to Mesa, If no problem is found we would
ask for return shipping. If a board fault exists (that's not customer caused) , we would ship
a warranty replacement card at no additional cost.

Technical things:

1. Its not a firmware issue. Firmware without a valid CRC will fail to load

2. A watchdog bite means communication failed for long enough to trigger the watchdog
This means major issue with communications. This could be a faulty 7I96S (though
it would be a very unlikely error type)  checking the card would eliminate it as a possible cause.

Not sure why loading the DKMS driver would cause you to lose your network, 
This needs to solved as a separate issue.

My guess is the issue is the common problem with the built in Realtek driver which requires:

1. Installing the Realtek 8168 DKMS driver
2. Disabling Ethernet and ASPM PCIE power management in the kernel command line

This thread details these operations:

forum.linuxcnc.org/27-driver-boards/5323...resh-install?start=0

In addition, it could also be that you still have some power saving /cstates>C1/speed switching enabled in the BIOS

I would skip that for now, make the machine move first, later when you are happy that it works, you can punish yourself with some fine tuning! :)
Set the base period to 100000 at first (write 60000 in the jitter value in StepConf wizard), see if you get latency warnings when running LinuxCNC, and if you do not, then you can lower that value in 10000 increments.

Category: General LinuxCNC Questions

I know Chats algo's arent perfect.. Its like a highschooler still.

 

I guess it's more like a hallucinating 8 year old who read too many twitter and youtube comments and thinks he knows everything about the world. And of course, don't listen to the people who wrote these algorithms, because they do anything in their power to pump up the hype.

And sure, these bots can be valuable in some niche area's such as sorting through huge amounts of data which would be impossible for humans, but for many things they're not better than mostly random guesses at the moment.

Remora - ethernet NVEM / EC300 / EC500 cnc board

Category: Computers and Hardware

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. 


 

Yes, you will need to configure both the INI and HAL files so LinuxCNC can use the additional axis. The NVEM config file you have used as all 6 axes configured. For the LinuxCNC configuration, I'd suggest posting questions in:

jitter stabilized at 32000, if I adopt these values ​​and my driver's resolution is 800, what reliable speed can I explore with the machine?

control stepper motors with two controllers

Category: Driver Boards

Often you can simply put some (schottky) diodes in series in the step and direction signals in between both "step generators" and the stepper motor drivers, but it depends on the actual hardware you have.

Another option that can work is to put some 74HC series logic in between and use that to switch signals. For example with a 74HC541 you can switch 8 digital signals on/off via the "G" inputs. You can then use a simple double throw switch to switch the "G" inputs of the TTL IC's.

In a more elaborate setup, you can control the "G" inputs with some microcontroller and you can make it as complex as you want or need.
