Results of latency test, list of computers tested for use with LinuxCNC

Category: Computers and Hardware

  Mainboard Asus P5E3 Pro
i first tested it with NVIDIA GForce GT 620  - Unexpected realtime delay on task 0 with period 25000
and now with a old RV370 [Radeon X300] that makes the change.

Having a field I/O fault is normal until LinuxCNC is running
(if nothing else, there will be a watchdog fault)

What does the command

ip a

return?

Five-Axis RTCP Features: G43.4 and G43.5 Equivalents in LinuxCNC

Category: G&M Codes

Hello,I am very interested in your conversation because I am experiencing the same problems. I use NX Simen and, of course, no LinuxCNC post-processor. So I have to make do with a post-processor that is as close as possible to Fanuc. I have an XYZBC configuration. trt. and I can't get a compliant configuration. I use NX Builder to modify the post-processor, but some, such as G43.4, are not interchangeable.Thank you for your help.

Recompiling the motmod modules to expose pos-cmd pins

Category: Advanced Configuration

This method uses simple_tp in teleop mode, so it doesn’t synchronize velocity and acceleration. I’m trying to hack it to work in coordinate mode instead. that way, we’ll be able to control LinuxCNC by sending continuous waypoints through HAL pins.
I don’t fully understand how coordinate mode works yet; I just discovered where the calculations take place in the code:

Hello, thank you for your reply.

I think it has helped me a little.

I have rewritten my files and based them on “lcec_configgen.”

I found the problem.
There was a second hal file in which it was hidden.

cia402.hal:16: insmod for lcec failed, returned -1HAL: ERROR: pin 'lcec.0.3.out-01' not found

Now I always get this error.Debug file information:Note: Using POSIX realtime./ethercat.hal:15: execv(./lcec_conf): No such file or directory./ethercat.hal:15: waitpid failed ./lcec_conf lcec_conf./ethercat.hal:15: ./lcec_conf exited without becoming ready2729Stopping realtime threadsUnloading hal componentsNote: Using POSIX realtime

7i76eu connection issues

Category: General LinuxCNC Questions

Okay I looked around and saw that the card should run without feild power all together. I have setup a static ip for 10.10.10.1/24

I can ping 10.10.10.10 with success but if I run up addr it still isnt visible. Maybe that's usual. Still on the linux cnc end of things with the updated 10.10.10.10 address for the card I am still getting it as unreachable

Alright, I have done some further digging here and realized I'm a jackass lmao. I have the cr11 led on which according to the manual is a feild io falt. I have been reading the wrong ip address I'm not establishing connection to the card I am assuming due to these power issues.

I am powering the card with 12v which according to there documentation is acceptable. I am getting 12v where I should be everything seems to be a go there. The jumper for setting feild i/o as vin input is in the correct position. I have unplugged everything unessisary from the card.

Retrofitting HURCO BMC30

Category: Milling Machines

So i have come some way on the BMC30, adjusted the PID:s a lot and the controller on the Servos as well, where certain I had some balls in the ball nuts where cracked but now I think  it was just the PID:s that were set way to stiff.

But know it seems to work quite good for the moment at leas good enough to progress to the ATC.

I have chosen to go with Probe basic as UI and now i struggle to understand the setup.

My machine that has a 24 pocket carousel ATC that is using a pneumatic motor for the tool changer and grey code encoder. The encoder is a 10 bit encoder which I have hooked up all the bits for and now I am trying to figure out how to digitally connect these to the software but I am not certain how to do this.

Anybody that has any experience how to setup such a ATC or can point me in some kind of direction?

Yes, you can run all field I/O on the 7I76UE at 12 V instead of the more common 24V
Note that this means all field inputs and outputs will run at 12V

Also note that for direct connection to field inputs, proximity sensors must be PNP (sourcing) mode.

NPN sensors require an added pullup resistor.

toggle2nist hangs when pressing an other button at the same time

Category: HAL

To illustrate my issue with toggle2nist a bit more I have made a simple hal file.
The hal file makes no other sens as to show problem easily for testing yourself. 


1. If I comment in 
net net-mist-off  => halui.program.stop
Linux runs as I expect. I can toggle the nist2 in halshow with set and clear.
If mist is switched off, a running program stops. I can start again and so on.

1. If I comment in 
net net-mist-on  => halui.program.stop
I can toggle the nist2 in halshow with set and clear only once.
If mist is switched on, a running program stops and the tog2nist.on LED is yellow all the time.

Is this working as expected?
# with this 2 lines each coolant shows a checkbox in the axis ui
# this is normaly part of the machine.hal / here only for test in the SIM-HAL-AXIS
#net coolant-mist      <=  iocontrol.0.coolant-mist
#net coolant-flood     <=  iocontrol.0.coolant-flood

#  start and stop the coolant.

loadrt toggle2nist names=tog2nist0
addf tog2nist0 servo-thread

net net-mist.is-on tog2nist0.is-on <= halui.mist.is-on
net net-mist-off tog2nist0.off  => halui.mist.off
net net-mist-on tog2nist0.on  => halui.mist.on

#net net-mist-off  => halui.program.stop
#net net-mist-on  => halui.program.stop

Mal eine ganz dumme Frage...
Wenn ich den IO-Bereich einer 7i76eu mit 12V versorge, darf ich dann auch auf die Input's die ca.12V eines Näherungssensors geben?

Look at the exact line that is executed to link the application.
You should be able to see the exact command with all values that are actually used.
Troubleshoot that line first. If that's wrong, fix the makefile.
