[SOLVED]linuxcnc Latency test ambiguous results

Category: General LinuxCNC Questions

I have these kernel parameters set "quiet isolcpus=2,3 acpi_irq_nobalance noirqbalance irqaffinity=0 processor.max_cstate=0 intel_idle.max_cstate=1"
From what I remember, better results are when you isolate 3rd and 4th core.
The "stress" test should not affect core 3 and 4.

Using npn Inductive sensor for end stop.

Category: Basic Configuration

To use NPN sensors with 7I76U inputs (which need a positive signal to actuate),
you must add a pullup resistor to each 7I76U input connected to a NPN switch.

+24V --> resistor_pin_1 --> resistor_pin_2 --> NPN output + 7I76U input

Suggested resistor value is 2.2K 1/2W

(PNP sensors need no additional components)

@cakeslob , I had a look at your hal file again and copied your spindle stuff exactly just changed for my pins etc and it's still the same. So I think that rules out a hal file problem. I don't think it's the vfd because I can change the speed manually by pressing the + and - manually in the  Axis GUI and it responses quick with no dips when changing speeds. 


Hmm probably going to have to do a halscope to see what is happening with that remora.sp0 and/or RPM signal when using css. The fact that it only does it while CSS is making this difficult to narrow down

just do a quick double check of my config ini/hal, and see if anything stands out. This is the config I used to test out threading and css the last time we talked. I dont think my halfile was a whole lot different, but maybe something in the ini file. Im still very new with lathe, but threading and css appear to function as intended.

EtherCAT + 7i96s + Internet Success was created by santy

EtherCAT + 7i96s + Internet Success

Category: EtherCAT

Hello everyone.

I managed to get 3 separate NICs in a Fujitsu Desktop with a PCIe adapter, and now i have successfully connected to EtherCAT, Mesa 7i96s, and the internet simultaneously.

I have done this to move a XX,Y,Z gantry. I have 2 motors for 2 Z axis, which will work independently in 2 separate Qtplasmac configs.

I have created a simple 7i96s config from PNCCONF, and tried to adapt it into my CIA402 config. There have been some errors in trying to boot QTplasmac, because i keep getting different errors like the following.



I have to comment this line otherwise the system doesnt boot.
# ---JOINT ASSOCIATED WITH THE Z AXIS---
#net plasmac:axis-position joint.3.pos-fb => plasmac.axis-z-position

when i comment that line out, the config almost starts but then i get this.
Traceback (most recent call last): File "/usr/bin/qtvcp", line 555, in _qtvcp = QTVCP() ^^^^^^^ File "/usr/bin/qtvcp", line 261, in __init__ window.load_extension(opts.usermod) File "/usr/lib/python3/dist-packages/qtvcp/qt_makegui.py", line 269, in load_extension methods, self[obj].handler_module, self[obj].handler_instance = self._load_handlers([handlerpath], self.halcomp, self[obj]) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/usr/lib/python3/dist-packages/qtvcp/qt_makegui.py", line 312, in _load_handlers objlist = h(halcomp, widgets, self.PATHS) # this sets the handler class signature ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/usr/share/qtvcp/screens/qtplasmac/qtplasmac_handler.py", line 6107, in get_handlers return [HandlerClass(halcomp, widgets, paths)] ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/usr/share/qtvcp/screens/qtplasmac/qtplasmac_handler.py", line 224, in __init__ float(self.iniFile.find('AXIS_Z', 'OFFSET_AV_RATIO')) * 60 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ TypeError: float() argument must be a string or a real number, not 'NoneType' 




My main goal would be to start the config, and double the X axis signal into 2 motors, altering the cia402 config.

basically get a main axis and a tandem axis with ethercat, which will have 2 home input from the mesa card.

remove the problem of having to comment out the line which provides plasmac z axis position *listed above*

get 2 different Z motor driver slaves to run for Z axis, one for one config, and one for the other

Startup QTplasmac and finish my config according to the machine



Could anyone provide some tips in the right direction please ??
I attach my config below.


Thank you
best regards

Thank you for the reply Daz, and the offer to help

I now have what appears to be a successfully flashed and converted ST to DAP-link.

Now I am at the point where I need to hook this newly converted DAP-link to the NVEM controller. Is there a wiring schematic somewhere or something that tells me which pads on the controller get which wires? The pads are not labeled on the controller.

I was just going down that road, I found a post where it was talked about, For now I did this:
BOOT_IMAGE=/boot/vmlinuz-6.1.0-33-rt-amd64 root=UUID=e5282ae9-3e96-4f4e-9c6c-19b3dd421c80 ro initrd=/install/gtk/initrd.gz quiet isolcpus=1,2 r8168.EEE=0 pcie_aspm=off nohz_full=1,2 
but I would like to try to add: rcu_nocbs

can you share your lspci result?

Thanks. :-) I was hoping to use the "emergency off" switch plate from our old oil burner, but I guess I tossed it at some point. So I "had" to paint another one red.

It's a double pole switch. One half turns off the spindle's outlet, the other half triggers an e-stop input on the Mesa.

Huh?

Please clarify.

What exactly do you intend to achieve?

The ping times are not terribly important _unless_ packets are dropped due to timeouts.
Default timeout setting is 80% of the servo period so those times look fine for a 1 KHz
servo thread.

Ok so I just checked and yes it has them on both sides. They are contact switches and they both work. I have pictures but I don't know how to send them.

Have you tried isolating the CPU cores?

I have the same processor, but a different motherboard, and the results are better.

It is possible that your problem is caused by something other than delays, but it is worth trying to improve the result.

Yeah, where to start looking?
When you turn the servo motor (if possible) and look at the relevant pos-fb pin in halshow, does the pin number count up/down? What value does the lcec.0.xxx.controlword have?
Vendor id and product code from "ethercat slaves -v" match the vid and pid fields in ethercat-conf.xml?
Any error messages from linuxcnc at startup, or errors in "sudo dmesg" that can help?
