Spindle control not showing in Axis window...

Category: Basic Configuration

First - I have NO idea what I did to fix it... but it is working now. I feel like I 'proved' the Infinite Monkey theorem ...(en.wikipedia.org/wiki/Infinite_monkey_theorem)

That said, when it WASN'T (or being pessimistic about the the future - when it DOESN'T) working, the target you refer to, was appearing but the DRO was not zeroing.

I'm going to do a text comparison of the now working INI and HAL files with the almost working INI and HAL. The almost working files allow me to start the router, move it around and homes without error... except it does not zero the DROs.

Strange behaviour of custom component

Category: Advanced Configuration

Guessing but it sounds like the component uses global C variables.
Check out 8.4 here linuxcnc.org/docs/html/hal/comp.html#_per_instance_data_storage if relevant.

Strange behaviour of custom component

Category: Advanced Configuration

Hello Gentlmen,

Excuse me, but once again I am facing weird behaviour of custom components file during its programming... 

I need 3 axis there fore I am using a 3pcs of components in the .hal file via count = 3..

I have many IOs stuff because component will communicate with profibus DP driver and it is basicly same as with ethercat but little bit different(other story) But long story short.. when I am homing there we have a custom homing subroutine and modes of driver are changing etc.. issue is comming - I have starting homing with single axis(over internal subroutine), any of them and mode of driver operation is changed over all components==all axis .. what exactly help me right now is have custom names of same component each but it is little bit tricky...

What the behaviour is this overflowing from one to other component in the single instance of lcnc?

Thanks En....

Axis 2 - touchscreen version of old friend

Category: AXIS

I don't find sim/gaxis, but I did find sim/gscreen, which is interesting. But I've also in the meantime found JT's Flexible UI thread, and I like the idea of being able to customize it easily. Having written a somewhat complex pyvcp panel for axis, that I now realize I can't use anywhere else, I'd rather the customization options are baked in from the start.

yes, i can confirm the setting are not saved.
There is an error.

Start with the option -i and -s don't work, there are errors, too.

Dear Giovanni, thanks for your manual.
For me point 9 doesn't worked. The start as standalone doesn't worked because there are errors.
For me it is working with a softlink and you don't have to copy and delete:
sudo ln -s /usr/share/linuxcnc/gladevcp/NativeCAM/ncam.py /usr/bin/ncam

For point 1 (and 2) i think it's easier with the command:
sudo apt install python3-lxml git

For point 2:
git clone https://github.com/freemoore/NativeCAM

Point 6: You use gedit, but it is not installed by default. Geany is installed by default from LinuyCNC.

Best regards

Michael

Usually omitting or deleting lines with HOME_...._velocity in the ini file and editing the homing and limit lines in hal is all it takes, but first:
-is the Y axis single drive/motor or tandem?
-is the Y axis the right choice for your use case? I usually do X axis as rotary.
-upload the hal and ini file so we can have a look.

Issue with OP Entry Delay and Failures in LinuxCNC + EtherCAT System

Category: EtherCAT

If remain -1 can have some problem on real machine ?

Normally the next version the ethercat, it should be more performant, but in reality on debian 10 there are no such problems

Inexpensive hardware setup: N95 Mini PC, Mesa 7I92T (Ethernet) and G540

Category: Computers and Hardware

Hi all, 

In case anyone else is interested in using inexpensive mini PCs and Mesa ethernet boards, I thought I'd share some details of my new setup. It's early days, but it seems to be working well--I'd be interested to hear about other people's experience with similar setups...

Mini PC, N95 $120 It's tiny, like 3-1/2" square!
Mesa 7192T $110 has ethernet and parallel port for the G540 (you need to build your own enclosure and supply 5v)
Gecko G540

I got the PC off Amazon:
www.amazon.com/dp/B0DGQ1P667?ref=ppx_yo2..._fed_asin_title&th=1
described as:
Mini PC Alder Lake-Ν95 (up to 3.4GHz) 4 Cores 4 Threads, Mini Computers 8GB DDR5 256GB M.2 SSD, Mini PC Dual Lan Support

Here are my somewhat cryptic notes about the configuration process. It's basically an assembly of techniques from other threads on this forum. I changed the IP address of the card from the default, but in hindsight I don't think that was really necessary.

Install linuxcnc from USB stick

Disable Turbo mode in BIOS (not sure this is really necessary)

(Note: there is no hyperthreading option in this particular machine)

Change mesa card jumper for "static IP from EEPROM"

edit /etc/network/interfaces to add static address for the card:
auto enp2s0
  iface enp2s0 inet static
    address 10.10.10.11
    netmask 255.255.255.0

sudo mesaflash --device 7I92T --addr 10.10.10.10 --write 7i92t_g540d.bin

change grub:
  isolcpus=2,3

===== At this point I was getting network timeouts. The fix for this has been posted on this forum, and is as follows: ============

Because of network latency issues it is necessary to install the dkms driver per this thread:
docs.google.com/document/d/1jeV_4VKzVmOI...ading=h.macj649sy0yq
Open a terminal window and Type the following lines: 
sudo apt update 
sudo dpkg -P raspi-firmware
sudo apt dist-upgrade
Note that the second line (sudo dpkg …) removes firmware for the raspberry pi incorrectly installed by Debian and is a bug out of our control

Type:
sudo apt update
you need to install some utilities. Type:
sudo apt install build-essential dkms 
If you have not installed a later kernel as described above install linux-headers. Type:
sudo apt install linux-headers-$(uname -r)
sudo apt install r8168-dkms

Flexible GUI

Category: Other User Interfaces

I got my touchscreen monitor delivered yesterday and just wanted to confirm that the issue I was having with touchscreen button not working right was a consequence of using Flex GUI in a virtual machine on windows. The Flex GUI that I made works perfectly on a real machine with touchscreen. For the real machine I am using a RPi 4b and a generic 10" touchscreen monitor.

For anyone else designing their GUI this way, I am using VirtualBox on a Windows 10 machine. The virtual Machine has LinuxCNC 2.9.4 installed from the live iso download. Here are the couple quirks I have found running it in the virtual machine. I want to stress that these issues don't exist once the .ui file is put on my RPi machine.
  1. touchscreen buttons don't respond as expected in virtual machine
  2. The machine will unexpectedly go to "Power Off" as soon as a motion command (Jog, MDI, or in a program) completes. Doesn't do it every time, but pretty often. Again, only in the virtual machine.

    I also want to again give thanks for this wonderful tool and to give a peek at what I am working on. I have a 3 axis benchtop mill (RF-45 size) that I converted to CNC a few years ago. I did this as a hobby and use the machine for my hobbies. It has been run with many things including LinuxCNC on an old tower PC with ancient monitor, keyboard and mouse, with GRBL on an Arduino hooked to a Netbook with my own Visual Basic interface, and I tried one of those standalone controllers, but sent it back because it was junk. I finally decided to just do it better and got a RPi 4b, installed LinuxCNC and have been working on an interface that for most of the way I use the mill can be done without ever touching a keyboard. I'll still have a small wireless keyboard with trackpad available if needed though. This is the interface I'm working on and I think it will suit me. I have the UI sized to perfectly fit the display that I bought to use as much space as possible. Thanks again for the very useful tool.

    John B

     

If you want to add that gui to the Flex examples just upload the ui file and I'll add it.

Need help making rotary axis behave like second spindle

Category: Advanced Configuration

I have a turning application that's better suited towards a constant RPM on the rotary. I have my A axis functioning fine right now with position control.

I'd love to be able to just issue a M3 S1000 $1 instead of playing with the inverse time mode approaches.

I've searched the forum and tried several things without luck. Honestly, anything HAL related is an instant headache nightmare for me. Believe it or not, I'm an embedded programmer and did ladder logic in college, but the HAL stuff just does NOT click for me. I'd be willing to pay for someone's time to figure this out for me. I have a project for my church that is way behind.

I'm using Probe Basic for the GUI. I'd be willing to give up some GUI control as long as I can issue gcode commands.

Attached are my current INI and primary HAL.

Tried: 
- Changing control_type from 1 to 0, but had no idea what else to do
- Considered the rosekins but that doesn't really apply to my needs

Other forum posts I've read:
C Axis as Second Spindle - LinuxCNC
Using A axis as second spindle with stepper motor - LinuxCNC
Lathe spindle question turning and milling. - LinuxCNC

Thank you.

rotary axis queston

Category: General LinuxCNC Questions

HI
I am wanting to add an optional rotary function to my table, to have a tubing cutter.  With another controller and software I just switched the Y axis control output cable to the rotary axis motor.  This is also the way it is done with my desktop laser to use its rotary optional drive assembly.
On my table I and using LinuxCNC software with a Mesa 7I76E card and QTPlasmaC GUI.  I have tried to leave out the Y home/limit entry in the pncconf setup, but it will not enable the Y axis.  I understand the need to do the homing operation so the software knows where it is for running a G-code.  After the homing I can position any axis to a location and then zero out the DRO and use that as a start position for the G-code. 
What I want is the Y axis not needing to home to be active.  This would allow me to home X and Z and position the Y to a zero position manually.
Thanks for your time
Tom V
