New install on previously working system

Category: Installing LinuxCNC

Running 2.9.5 on a RPi 4. I had this system running well earlier, until I tried to update Easy Probe. Now, I can't communicate with the Mesa card on ETH0.

I had to replace my main PC, which wants to use the 192.168.1.x addresses. I changed the jumpers on my 7i96s to 10.10.10.10, and I can ping the card.

When I run LinuxCNC, I get the attached report.
Any suggestions?

Dynamic soft limits was created by Rockwood

Dynamic soft limits

Category: PathPilot

Hey All,
I'm not sure if this is the right place for this. But I'm working with a Tormach 1500MX that has a PathPilot control.
I built a complicated fixture for running the same part over and over. I wanted to have the soft limits prevent the tool from hitting the fixture. Which means having different X and Y limits when the Z axis is low enough to have the tool in the fixture. Also to prevent Z from lowering into the fixture unless X and Y are correctly positioned.

I ended up with this added to tormach's postgui hal file:

#rockwood edit , the below is for setting dynamic soft limits to protect from crashing into fixture when in "run" mode, "Setup" accessed with the built in tormach keyswitch, will have full travel. All units are inches.
#If Z < -3.187: X and Y limits switch to narrow windows (X:[14.349-15.175], Y:[5.674-6.559]); else use factory limits.
# Z min is -3.187 by default; becomes -11.494 when BOTH X and Y are within their narrow windows.


#load and name components I will need later,  and2 components have to be added in "tormach_mill_ethercat_csp.hal"

I've tested it, just jogging around and with MDI commands. It seems to be working. But this is my first time using linuxCNC. So I'd love a reality check from anyone more familiar. Does this make sense or is there a better way to do it? Am I adding too much to the servo thread? Is there something I should check to make sure I'm not slowing stuff down too much? 

In the future, I want to get rid of all the hard-coded numbers. I want to store them in another file or at least one clear location in the postgui file. Preferably, I could process the "narrow window" numbers from a work offset, so I can move the fixture in the future and change the offset. But I would want to then lock that or all offsets from being edited easily, maybe using the same setup mode keyswitch. I'm not sure how to handle that yet. If anyone has ideas, I'd love to hear them.

Thanks for your time!

I had time for some investigation. When touchof before running a gcode, (self.gui_path) in the file touchoff.py  leads to /usr/lib/libflexgui. but after running a gcode (self.gui_path) contains /home/miller/linuxcnc/configs.

Toolchange popup is affected also the same way.

Hi meister,

Really cool project! I was thinking about combining FPGA support and  LinuxCNC on an  Ultra96  board (Xilinx/AMD Ultrascale device, 4x ARM64 cores and FPGA on the same chip) for years, but had no clue how the HAL messaging works. But with your UDP example as a base it was really easy! Below is a pic of the demo system, which is the Ultra96 itself, a simple self made interface board and the CNC Shield v3.0 at the top. And of course a video . :-)When I was done I saw you had added and experimental "axi" plugin and it looks like you had the same idea like me, but it did not work for me. In case you are interested, I could send my versions of the verilog and and c-code portion and maybe you could add it in a later version of your code generation magic.

Yeah, I have home and limit switches. They came with the machine, so I was able to wire them in the control board.


That's nice mate, but my reply was to the OP.

The SmartSerial is also a latency related issue

Pinning the Ethernet IRQ to the top processor in conjunction with isolcpus=LastCPU
can also help a lot (LastCPU =3 for a 4 core processor)

This script can do this temporarily:

Thanks to all, I reinstalled, then installed dkms-r8168 pkg. This fixed the issue.
Now the driver is r8168 instead of r8169.

LCNC 2.9.5 - How to jog with a wireless xbox bt controller was created by phew

LCNC 2.9.5 - How to jog with a wireless xbox bt controller

Category: Basic Configuration

Hey,

I am trying to set up my xbox controller to jog a three axis machine (y-gantry). Using a bluetooth dongle I had to fiddle around a bit (and install xpadneo) to get the controller to connect to the system but I eventually got there and do see input when pressing buttons/moving the joysticks.

I was digging into LinuxCNC a few years ago but then life happened and I had to put the project on ice up until now. This is my first home-built CNC (wood router) and I am very new to all of this.

My goal is to be able to move the X, Y (gantry) and Z axis using the gaming controller when there is no gcode being executed.

Currently this is a parport setup and the stepper motors are not actually installed on ball screws so I do not mess up anything while testing. I am planning on switching to a mesa card in the near future.

net xbox-x-vel => halui.axis.x.analog

With this setup I can see input from the controller in halshow:

 

However, joint.*.vel-cmd always stays 0 and obviously the stepper motors are not spinning. Also I am not sure what mode I have to use, but I also tried setting halui.mode.manual and halui.mode.teleop using the [Set] button in halshow, but this did not change anything.

Setting it up like this will not allow the machine to start when the Xbox Controller is not connected as it expects the controller to be found. The controller will shut itself off if not being used for a certain period of time and this will also result in an error popping up in axis ui.

I think my current approach is way more complicated and clumsy than it actually needs to be, but the learning curve seems to be pretty steep for me and therefore I probably resorted to using way more AI generated code than I should have.

How do I
  1. set this up correctly so the Xbox Controller input can actually controll the X, Y and Z axis?
  2. set this up in a way so the controller does not need to be connected in order for the machine to start and won't result in an error when the controller disconnects for some reason
Any help is appreciated!

I managed to get it up and running. First I disabled
  • Secure boot
  • Intel SpeedStep
  • PCIe ASPM
  • TurboBoost 
in the bios. Than I could establish a connection and steer the axles. Afterwards I enabled one by one except PCIe ASPM again and I could steer the axles. I ran the above test in this state.
However, some errors remain:

I'll try to fix these - however if anybody has a quick idea what needs to be done to fix them your help is always appreciated :-)
Thank you so far for your quick help to get the machine up and running again!

VLANs or multiple ethernet cards?

Category: Computers and Hardware

I would put 2 NICS in the PC, daisy chain one NIC to your Ethernet slaves and use the either to connect your PC to your network, with or without a VLAN.

Ethercat is likened to a high speed train with packets getting on and off without the train stopping... so no benefit in more complex networking
