I cannot find the limits I marked in the picture on halshow.
When I change the limits below joint_0, the machine stops at the limit, but I cannot move it again with the jog keys.


 

hi
Thanks @tommylight and @elovalvo
these are two paths that I have already taken without success
the headers for the kernerl 6.6.45-rt39-v8-16k are not found.

Now I'm going away for a few days, when I come back we'll see

thanks a lot

Hello
I use QtDragon with versa probe to automatically measure tool height. I am following the documentation here (linuxcnc.org/docs/devel/html/gui/qtdragon.html#_versa_probe) to setup various config params like probe height, etc. I have a gcode program generated with Fusion360 where Z zero is set to top of the work piece. Before running the program, I set the block height to work piece height (measured manually). When program is started, it correctly go to the tool height sensor location and probes the length of the tool ans new value for Z is set. However this Z value does not seem to become zero at the top of the stock height (Which is how I setup the codinate system in Fusion). If I stop the program, the G54 Z changes and the new value seem to be correctly alighned with Z of zero at top of the stock. I am new to this proebe system and would like to understand the reasoning.

Thanks

Hello everyone,
Thank you for this forum and the work accomplished. Knowing a little the possibilities of configuration of this software this update is for essential.
a few years ago I built a complete 5-axis continuous milling machine under linuxcnc.
It works very well with a // port and a STV2 “break out”, DMA860H drivers and a VFD. so I control :
- 5 continuous axes
- Spindle stop/run/speed ( G code )

However, not enough I/O for coolant and other functions.

The only drawback is that I'm “obviously” lacking precision with 5 continuous axes. I therefore need to install rotary encoders on my B/C axes. But there's no more possibility on my Break Out card. So I have to change my system completely.
I want to start with Raspberry Pi4 . Despite the tables above, I'm not sure about my choice of Mesa boards. What would you recommend for such a configuration?

Thank you in advance.

 

  I’m trying to retrofit an old plasma with a 7i97t and I’m having a hard time getting things working.I can’t find the brand of the servos or drivers, but I do have most of a manual and the bob for the drivers says automation direct.The servos worked before I started my retrofit.The encoders seem to work fine in linuxcnc.They spin if I give them analog power.But they just slowly drift when enabled, regardless if they’re wired to 7i97t or not.If I connect my multimeter to the 10v analog while they enabled and try to jog them, I don’t get anything.I tried tuning a bit, but it doesn’t seem like they getting any input.I assume either I wired something wrong or I configured something wrong.wiringThe 7i97t manual referencing analog survo drive interface asks the drives common or gnd signal to be connected to the 7i97t power gnd. I didn’t this. Is the 7i97t power gnd p3? The drives bob has analog ground, digital ground, field ground, encoder ground, and shield ground. I guess the digital ground is the common, but I’m not sure.Speaking of grounds, my power supply’s ground doesn’t ground to the frame. Should it? The 7i97t grounds to the frame with a bolt. the 10v analog twisted pair shield grounds to the shield ground on the drives bob, which seems to ground to frame. The other end is not grounded.I only power I have to the 7i97t is 5v to p3 and 24v to tb4 i/o’s.I used mesact to configure. I’m sure there’s plenty I did wrong in this step. The minimal descriptions were not enough for my limited understanding. Instead of confusing everyone with my logic, I’ll just attach an ini.I did notice the tuning tutorial Hal scoping analogout, but I only have pwnout. Not sure if that’s relevant.Any help would be greatly appreciated.  

Hello Rabin,

I'm working for similar setup. XZ-C/Spindle Can you share your configuration example, It would be much helpful.

Thanks

Thanks so much!



unlike the installation of the EtherCAT packages that gives me an error


 

i don't know what it depends on, maybe we need to wait for Etherlab to update the repositories

Maybe try a 'toggle' component:
linuxcnc.org/docs/devel/html/man/man9/toggle.9.html

Now the toggle is working

I realy appreciate your help

Good day

Philip

Yes please
Is there a way to see how you do (screenshot or whatever) in order to learn a bit also?

It worked. Many thanks

Step/dir pins are output only

So you need the spindle encoder and 2 step/dir indexes?
 

I absolutely need the encoder. However I only have 2 motors so is it possible to use the other axis step/dir instead? So pin tb1 14 and following?

Thank you

intermitent problem! try pulling and pushing the card into the pci slot few time to try to get a good contact, the pci copper fingers get oxidised after few years unused.

My understanding is that your computer reboots only when you run Linuxcnc?
You could install the latest Linuxcnc and test your lathe  with your current setup files (ini, hal, ui …)

The apt installation is better if your not doing dev work.
