Ok I have pushed a fix for the 'PREFERENCE_FILE_PATH = qtaxis.pref' error.
Thanks for the detailed report

I think reload works for graphics, but it does not reset the view or clear the plot lines.
I loaded chips.ngc, then edited the tool number and reloaded - it used the new tool number.
I think it should at ;least clear the plot lines.
I see the gcode display does not reload with the button push though.

I also didn't know linuxcnc's interpreter will always reload the file when you press start.
I don't think that's a very good idea but I guess I should add a check for changes to warn the user.

For now I will have reload clear the plot and fix the gcode not updating.
Thank you again.

I've gone through this thread and used the script, made the obvious mistakes of not having irqbalancer installed and having the wrong ip (10.10.10.1 instead of 10.10.10.11) in the script.  I've fixed all that, but I am still having a near immediate error when I start of Unexpected realtime delay on task 0 with period 1000000 followed by a hm2/hm2_7i76e.0: Smart Serial Port 0: Doit not cleared from previous servo thread....

I can move the machine around and run the spindle (modbus issues resolved with group admission change), but after a short while I get an error finishing read and the machine goes in to fault.

The hardware was all working with 2.8, so I don't think there is something that has died as it will all still work in 2.8, it's just this realtime delay issue.  I hate to bug anyone with this as I feel like I just haven't done enough due diligence, but this thread seems to be hitting all the high spots related to latency and I have not managed to resolve it.  Any help would be greatly appreciated.

Kind regards,

Sam

Thanks, that's exactly the point I was trying to make.  I think it's valuable to have a subforum within the User Interface section dedicated to various hardware user interface elements.  Maybe my mistake was using the somewhat old-fashioned "HMI" (Human-Machine Interface) term in when pleading my case, but it's really synonymous with "User Interface." 

With all due respect to JT, I still don't feel like the Computer Hardware subforum is the right place for those discussions. 

 

Yeah I agree about it not being mixed with Computers as it's generally not "computer" hardware anymore than a Mesa card is. At some level it connects to a computer but if you don't consider it part of the computer it does not belong there.....

For example you can buy various EtherCAT physical HMIs on Aliexpress, or as mentioned you can use a 7i73 to make your own, or use something like arduino-connector to build one.....I don't think any of that's part of a computer but it's certainly belongs in an HMI subforum.

Another point for it being part of User Interfaces I was trying to make JT himself would probably get since he's been working on JET. JET obviously belongs in user interfaces. I've been working on an all-in-one control device, touchscreen, MPG, buttons, knobs, keyboard, etc. If I used JET to make a UI, I'm probably not going to put a FeedRato O/R on the UI because I have a physical encoder for it, same with spindle control, run/stop, etc. It's all part of the same thing, it's the hardware side of the User Interface. Like you may use Gmoccapy because you only use a touchscreen, you may use something with less UI controls because you have more hardware controls.

If I go to the Computer's section it's because I want to find out if mobile CPUs are OK, or how much RAM I might expect to use, or what NIC plays nice with Mesa cards. I wouldn't even expect to go there to find out about whether a USB MPG is OK, if it existed I'd expect to find that in a hardware subforum of User Interfaces.

How can I improve the latency in the bios?

I think you need to read joint.N.pos-fb for X & Y and save the last position and calc the distance moved in fperiod
If both pins have a value, use pythagoras therom to calulate the velocity (C in this diagram)
en.wikipedia.org/wiki/Pythagorean_theorem
otherwise report the value for the moving axis.

Note if X& Y are both at max velocity, the actual velocity will be higher because the hypotenuse is longer than the x & Y elements

I'm trying to figure out how to display the actual tool velocity in at least the XY plane. For example if the tool is moving in the X direction at 10 IPM and in the Y direction at 20 IPM what is the formula to figure out the tool velocity?

Regarding latency, have a read through this:

Even on my feet, i have fingers crossed!

Just in case even the above line does not work, type this in a terminal
sudo apt purge brltty*
Enter
-
Most Linux distros will install brltty if they detect a non standard keyboard, like having multimedia buttons and pots, smart card readers, fingerprint readers, etc.
Brltty is used for Braile keyboards.

Some distros also have XWayland that can be choosen at login, most XOrg stuff should work OK with it and so do Wayland only apps.

Hi all,
I have a problem with my STM32F207 board. I cannot get the voltage on physical out pin cnahged. When I for example setp remora.output.3 to logical "1" the voltage does not change on a physical pin, while in HAL Configuration it sets to "True".
The board is configured with "nvem-full-config.txt" from github.com/scottalford75/Remora-NVEM/blo...nvem-full-config.txt 
Does anyone knows what may be a reason for this behaviour?

Hi,

*sends virtual pizza and ice cream*
Nice !

I am now going to test the scurve trajectory planner on the production machine.
It starts up : using posix realtime.

Wish me luck, fingers crossed.
Will make a youtube video once again.

Please post your config xml file.
There seems to be a lot of unmatched datagrams
also your latency looks pretty awful. Please work on cleaning that up in the BIOS settings.

I have 2 spindles in my mill 1 to z axis 1 to y axis  iso40 taper that have sensor for tool detection and hydraulic electrovalve for locking tool.
Also each spindle has gearbox with 2 positions
with sensor in which position is and hydraulic electrovalve for changing gears to position 1 or 2.
I plan to use encoders on spindles for rigid tapping.
The spindles can't driven together because there is only 1 inverter and selection which spindle will work is done via 3 phase relay.
Inverter gets -10v +10v analog input and enable signal.
real time splindle hal component supports gears but motion.spindle not.
Which component must use spindle or motion.spindle?
pncconf by default setup in config motion.spindle how can use gears 1 and 2 for motion.spindle?
