I don't really know what dpkg-checkbuilddeps does. If it lists the packages required to build linuxcnc, then I'd say no, because that is the set of libraries you need to compile linuxcnc.

The size of the structure is in the message, so you can check the version of
your application, against the version of linuxcnc that you are communicating
with. In my case, I just stop if there is a mismatch - if you want to
support multiple versions, you need to manage version changes yourself ie
create a constant for each size when versions change. Again, just a half
solution.

Re: [Emc-developers] incremental change to linuxcnc's APIs for user interfaces
(The summary of those bugs is: the serial number method for UIs to ensure a message is acted upon by task simply does not work when there is not just one UI. No simple modification will make it work, and no one in the project in 10+ years has taken the time to understand NML with the depth necessary to suggest a correct approach.) 1. Copy linuxcnc.nml to your run directory. 2. Edit linuxcnc.nml and create another configuration section for your UI 3. Edit your .ini file and add the NML_FILE configuration 4. When your UI connects to NML, use the name of the new nml section. I run axis on the local machine, then remote to it using keystick. Keystick still works because it makes its own NML connection keystick ... src/emc/usr_intf/keystick.cc emcStatusBuffer = new RCS_STAT_CHANNEL(emcFormat, emcStatus, keystick, emc_nmlfile); linuxcncrsh doesn't work because it uses a common library (that other UIs use) to connect to NML. It uses the same configuration, xemc. src/emc/usr_intf/shcom.cc emcStatusBuffer = new RCS_STAT_CHANNEL(emcFormat, emcStatus, xemc, emc_nmlfile); Everything that uses this library can't run simultaneously - emcsh, emcrsh, emclcd, axis - axis hard codes the xemc configuration in src/emc/usr_intf/axis/extensions/emcmodule.cc - so axis, and anything that uses the emcmodule python library fail. RCS_STAT_CHANNEL *c = new RCS_STAT_CHANNEL(emcFormat, emcStatus, xemc, file); So, you can have multiple UIs. However, if an upgraded API allows for other new functionality, I'm all for it. -- Comprehensive Server Monitoring with Site24x7. Monitor 10 servers for $9/Month.

As has already been mentioned, you can whatever you want with as many threads as you want. It is up to you to manage them and how they interface with whatever you interface. My VFD Modbus component is a user hal component that spawns a thread to do the USB rs485 comms. I have to manage how my thread communicates with hal. However, if you have a requirement that has a very certain predetermined thread cycle time it sounds like you should be writing a real time hal component - either your own component or a comp component.

Re: [Emc-developers] GCode preview in C++ (Qt)
I’m working on a couple of projects. I’m trying to improve GWiz. I started trying to tweak the UI – but the wxPython screens wasted so much of my time I gave up and just re-wrote it in Qt. I want to add a GCode preview so I can see what the wizards are doing (I use GWiz for my cnc-lathe – I have collection of wizards that I use to build up a simple lathe program). My other project is a QT UI. Originally I started with my own XML format mixed with Qt’s jscript. I made some progress with this, but got distracted on other projects. This was using 4.7. I read that the scripting I was using was going to be discontinued, so, as you suggested, I started version 2 using Qt 2 and QML. I’ve only done a small amount of work, but QML, although flexible, seems a bit slow. When I get the preview working in my GWiz port, I’ll then add it to the Qt UI. The main reason I started writing a new UI was to work with my small LCD screens on my pendant. I also found out that Qt GUI apps don’t need X11 to work. They can use the frame buffer directly – which is what my USB LCD uses. It should also work with RPi and BBB. I was aware of your changes the NML infrastructure, and I’ve always had them in the back of my mind as to how they would affect my code.

[Emc-developers] MDI in joint mode
Is it possible to issue MDI or equivalent commands in joint mode? For example, on my robot arm, I want to move joint 2 to 45 degrees. I'm guessing no, because you have to be in MDI mode to issue MDI commands and you can only be in MDI mode when in world mode. If this is the case, are there low level commands (nml?) that can be used to move to an exact position? -- Sponsored by Intel(R) XDK Develop, test and display web and hybrid apps with a single code base.

Getting it to work in realtime mode is probably going to require rewriting the generated ikfast C++ module into C as Michael suggested.

Re: [Emc-developers] development setups
I have a similar setup, but replace MAC with Windows PC. Any serious development is done in a virtual machine on my PC. All my linuxcnc boxes are too slow (and remotely connected) to provide a nice development experience. I use the simulator build of linuxcnc. Only after I think I have finished coding do I move to the real system to test, using lots of remote xterms and vi (through Cygwin/X). I also do my CAM stuff on my Windows PC and use samba (smbclient) to copy files from a windows share. Originally, I rooted my DNS232 NAS box and installed git on it to be my always on source code repository. I also installed nfs, but I rarely use it because I mainly use git. There are many NAS boxes that can be rooted. There are also many that are designed to allow packages to be installed (I also have a Synology box that allows that). Recently I installed a small dedicated Windows Server (running databases and other things), and this is now my source code repository. Frank -Original Message- From: andy pugh [mailto:bodge...@gmail.com] Sent: Friday, 23 August 2013 10:49 PM To: EMC developers Subject: [Emc-developers] development setups There has to be a more sensible way to do this. I have a bare motherboard with 8GB flash that is my LinuxCNC development hardware. It sits on a book-shelf behind the TV, which acts as a monitor when required. This has various bits of Mesa hardware festooned all over it. I also have an iMac with a 27 screen and a comfy chair. This is where I prefer to sit when coding. Previously I have been running Eclipse (and before that Xcode) on the Mac with the code stored on the 8GB ssd on the Linux system and shared to the Mac. (then compiling and testing through an ssh terminal (and X-forwarding when I need to see the Axis interface)). This works OK, when it works. The drawbacks are that if the iMac loses contact with the share for any reason, then Eclipse gets upset, can't save the workspace file, and the whole project needs to be set up from scratch again. Also X-forwarding only works once per login. I have to log out and in again to re-enable it. Now that I appear to be swapping between 32-bit and 64-bit systems rather frequently I decided it made more sense to keep the git repository on my NAS, then Eclipse should never lose it and all my LinuxCNC machines can share the same code repository. Does that seem logical? Setting up the NFS share from the Mac to the NAS was easy, it has autofs built-in and basically it just works. I have not yet managed to get the LinuxCNC machine to work properly in the same way. I spent several hours with a chap on the IRC on the problem on wednesday, and at one point it appeared that we had cracked it with a change to the timeout in the mount command, but it turned out to be a fluke, and reconnection via an fstab entry or by a manual mount always fails. Re-installaion from scratch of 12.04 Lubuntu did not help, nor did a clean installation from the 10.04 LiveCD. I also tried installing Autofs on the LinuxCNC machine, and that appears to simply not work at all. I _did_ manage to set up fstab to connect to the NAS via a Samba share, but that was unusably slow (there is no reason to think that an NFS share would be faster, of course) So, now I am back with the original setup, which will be OK until next time I need to swap OS-es on the dev machine, at which point I will have to re-create the git-repo from the LinuxCNC server, re-install all the dependencies and the other tools and accept that in the process I lose all the non-pushed branches. Given the setup (monitor, keyboard and chair belong to the Mac, Mac can see NAS, Linux Machine can't see NAS, Linux Machine is frequently nuked, can anyone suggest a sensible way to work?

Re: [Emc-developers] Fwd: [emc:bugs] #328 Problem using AXIS together with HALUI
Isn't this just the fact that the buffers can't be shared? If you want a command buffer don't you need to edit the linuxcnc.nml file and allocate a buffer for you process with a unique name? I had a problem where I was using Axis + Linuxcncrsh. After running for a couple of hours my job stopped working properly. It looked like it was executing one line of gcode every 2 seconds. Axis and linuxcncrsh use the same named buffer.

I did run into the problem before in a different context: I tried to implement a remote procedure call over NML using the existing (fishy) interaction pattern, and that failed for the reasons you describe; at the time I did not drill down like you did - congratulations for the stamina in identifying and fixing this! To verify, is the scenario as follows?: task A writes a command+local serial into the command buffer the command consumer is late in processing the command task B goes ahead and also writes a command to the buffer with its own serial B's command gets executed and 'acknowledged' the acknowlegdement for A's command necessarily fails due to serial mismatch, or lack of an ack altogether If this is the case, then I would see more than option to address the issue: as you have done, mutate the buffer into a queue *) stay with the single command buffer, but make producers aware of a command being present but not yet finished so the write does not happen before completion the globally uniqe serial surely helps, but afaict alone it is not sufficient to protect against the problem I am positive you are onto something fundamental here. Before adopting the patch my suggestion would be: we need to create a test case which identifies the current problem, even if only for regression tests. This might be a bit involved given all the moving parts. It might be easier to replicate the code sequence into small test programs and verify that the overwrite happens. the underlying problem is an unprotected write to a shared resource, and there might be more than one way to fix it (see above); it might make sense to adopt a method which is less of a wholesale change (I dont suggest it exists; just saying - it might make sense to investigate if there is a single fix to the issue at a different level) it might make sense to reconsider the usage of serials altogether. What they are for is correlating origin and command for replies; hence a tuple (local serial, originator id) would do the same trick; provided the originator ID is known to be unique. The reason why I am raising this is - a globally unique serial generator either needs shared memory, or - in the distributed case - a RPC-type service. Note full distribution of components is a goal for the future replacement of NML by zmq and protobuf which I'm working on (or rather would like to work once I have the RTOS work out the door). Interested how you see this. best regards, and congratulations Michael *) I would think the queue would protect against overwriting of commands alone; NB the possibly clash in non-unique serial numbers still exists: meaning the combination of single command buffer, write protect if command present, and serial/unique originator tuples might do the trick too. As a matter of style, I think your patch - making the command input a queue proper - is more up to the point though.

If I use HALUI excessively I've found that axis is blocked some times. Even more problematic for me is the fact that in some cases the HALUI action get lost. After investigating the involved code I've found the reason. I'll try to describe my thoughts: The communication between UI and EMCTASK is done by shared mem buffers (cmd + status).

It would be nice if we could embed the linuxcnc backtrace into GWiz, so when we string together a few commands, we could get a visual display of what we are programming. And as you say, enhancing GWiz to support script wizards would be awesome.

Re: [Emc-developers] Future Minimum Display Resolution?
I've been building pendants that use small 3.2 LCD displays. My first version just used a simple command based interface (fill rectangle, draw straight line, draw text), driven by a python menu add on, which runs in parallel with Axis. (http://www.franksworkshop.com.au/CNC/LathePendant/LathePendant.htm) Version 2 is a high speed USB version that acts like a USB display. When X11 is set up properly, runs as a secondary (or tertiary) display. I've also managed to get one of these (http://www.soundgraph.com/fingervu436-feature-en/) working, including touchscreen. Unfortunately, their resolutions are too low (400x240 and 480x272) to be used with axis, so I've been writing a Qt version. It is data driven - an XML file defines the layout and functionality. Each xml configuration is a screen-set. To keep it flexible, I've got one that looks like axis, one for each of my displays, and I plan to do a Mock3 one. Currently it can do basic functionality - start/stop/pause, load etc. It displays GCode. It uses gremlin to embed a preview, but you can't interact with it unless you use a mouse or touchscreen. It can also embed vismach, and a camera display. It can also use QtScript (JavaScript, no python :). The plan is to build a GUI editor. I've been distracted over the last couple of months. In the next few weeks I'll post a demo, to see if there is any interest in yet another GUI. The current plan is to use it as a secondary display on the pendant, with axis as the primary. It just depends on how much work I feel like doing on it. Another workshop project was to build a monitor slide away draw. I don't have any pictures yet, but I used a AOV e2243Fw2k (http://www.aocmonitorap.com/anz/monitor_306.php) monitor which is 12.9mm thick. It folds down and slides away using only about 20mm of space. Unfortunately to get it to work, I had to remove the stand (where the interface electronics is located), shave off a lot of plastic, and make a new holder for the interface electronics. It worked fine for a while, but now it seems to shutdown every time I fold it out of the way. So, the next version will probably be this (http://www.engadget.com/2012/03/17/gechic-on-lap-1302-portable-monitor-vide o/), which is only 1366x768, so back to the OP, that will be my minimum resolution for axis. -Original Message- From: Darren Conway [mailto:darren.con...@xtra.co.nz] Sent: Friday, 23 March 2012 5:09 PM To: emc-developers@lists.sourceforge.net Subject: Re: [Emc-developers] Future Minimum Display Resolution?

[Emc-developers] Using github to host linuxcnc repository
I'm new to git so I may have completely misunderstood what git can do, but... I have more than one linuxcnc machine now, and they all have customisations to the source. As I understand it, I should be able to up my own main repository clone of linuxcnc. Then, each of my cnc machines can then clone the source from this main repository, and push changes to it. Every now and then I'd pull the latest linuxcnc main branch to this main server, and update the cnc machines. First question, is this possible? Is this the right way to do it? Second question, can this main repository be set up on github? Given that github is free, it seems like a good place to store it. Any idea how?

[Emc-developers] Patch: Jog Speed exceeds axis MAX_VELOCITY
I posted this in the emc-users group because I thought it was a configuration problem, but it appears to be a software issue. This only happens on a gantry system. When axis starts, emc is in EMC_TRAJ_MODE_FREE, meaning all axis can be jogged freely. axis uses the EMC_AXIS_JOG command which checks that the requested velocity does not exceed the MAX_VELOCITY value in [AXIS_n] With a gantry, emc starts in EMC_TRAJ_MODE_FREE, but after it has been homed, it moves into EMC_TRAJ_MODE_TELEOP. axis will now jog using the SetTeleopVector command by specifying the velocity as the current jog velocity, or, if shift is being pressed, [TRAJ]MAX_VELOCITY. This is the first issue - axis does not look at the [AXIS_n] max velocities when jogging in teleop mode. However, I feel the real problem is that there is no MAX_VELOCITY checking when executing the emcTrajSetTeleopVector() function. So this patch addresses this by restricting the velocity in a teleop vector command to the values of [AXIS_n]MAX_VELOCITY. I don't know how else TELEOP mode is used, or if this can cause other issues. Or if the axis number mappings may cause other issues. The new methods, setPoseByAxis and getPoseByAxis could also be move to a more general place.

[Emc-developers] EMC+RTNET
I've been playing around with RTNet (realtime ethernet). I've been looking at it as an alternative to parallel ports, and internal cards. I've built an embedded slave using the Atmel NGW100 board. I have a test application that runs on RTAI linux (the master), which reads the encoder and IO statuses, does PID calculations, then sends PWM and IO ouputs. The unoptimised code can run at 200Hz. I'm hoping to get this up to 1kHz. This is driving my dinky robot arm (6v 30mA motors, encoder, 485:1 gearbox). On top of RTNet runs the TDMA protocl, time division multiple access. The master sends out a sync frame at the start of every period (current every 5ms - 200Hz). The 5ms period is divided up into time slots, and the master, and each slave are allocated one or more slots to send. Now I'm trying to integrate it into EMC and I have a couple of issues. 1) RTNET wants to run the rtai timer in one-shot mode. So, I can either set the EMC base thread to run at a high rate so RTNET can get close to when it wants the timer to be fired, or I can modify EMC to use the one-shot timer instead of the periodic timer. (RTNET has the option of not starting the rtai timer and use whatever is active). How will the one-shot timer effect EMC threads? I'm guessing this will introduce jitter. Is this a problem for a servo system? 2) As described above, the time on the ethernet wire will be divided up into 5ms periods, with slots defined as... 0ms | 0.1ms| .3ms Sync | Slot 0 | Slot 1 | Slave sends encoders | Master sends PWM info In order for this to work, I need to be able to synchronise the Sync frame of RTNet (the start of the period), with the servo thread in EMC (with offset). Ideally, when the EMC servo thread starts processing, RTNet has already received the data from wire, and it is ready to be processed. So I need to set the Rtnet Sync frame to begin at servo thread time - (0.1ms + transmission delay). Rtnet currently doesn't have a way to do this. Does EMC? If not, I need to change either EMC or RTNET to support this. Does EMC need a facility like this? On the Rtnet mailing lists, I was asked if EMC supports realtime events like Fieldbus, but I have no idea what it is? 3) And finally, when I create my realtime hal component to do this, should I be using the function interface of EMC, or just use RTAI events? If I use hal functions, then I rely on getting question 2) solved. I need a read() function to be called at the start of the cycle, and a write() at the end. Then I need to ensure they are called at the correct times. The other way I was thinking of handling it would be to use RTAI directly, setting up a read task and a write tasks that fired independently, and just kept the hal pins and paramaters up to date. This would have the problem of possibly being 0.5 - 1.0 cycles out of sync, but then there wouldn't be timing issues of missing read/write time slots. Any thoughts?

Re: [Emc-developers] Shared memory errors
For those that are interested, I found this on the site below in the nml tutorial document... For read() . If a process reads a message from a non-queued buffer: - the buffer is empty for that process - other processes will still be able to read the message . If a process reads a message from a queued buffer: - that message is removed for all processes - other processes will not be able to read the message For peek() - with respect to other processes, does not affect the buffer in any way, queued or non-queued . subsequently, other process write_if_read operations will fail - with respect to this process: . for a non-queued buffer, behaves just like a read . for a queued buffer, subsequent peeks will return no message until another read operation by any process Emc.nml has the error buffer defined as queued, which makes sense because you don't want to lose the error messages, but leaves me in a bit of a pickle because, although peek() works well, it is a race condition between me peeking and axis reading. -Original Message- From: Frank Tkalcevic [mailto:fr...@franksworkshop.com.au] Sent: Wednesday, 22 July 2009 1:47 PM To: 'EMC developers' Subject: RE: [Emc-developers] Shared memory errors For everything you wanted to know about NML but were afraid to ask http://www.isd.mel.nist.gov/projects/rcslib/NMLcpp.html -Original Message- From: Jeff Epler [mailto:jep...@unpythonic.net] Sent: Wednesday, 22 July 2009 8:51 AM To: EMC developers Subject: Re: [Emc-developers] Shared memory errors On Wed, Jul 22, 2009 at 08:00:14AM +1000, Frank Tkalcevic wrote: I'm having another issue with reading messages from the error channel.

Re: [Emc-developers] Axis rewrite - GUI/use cases suggestions

Of course, you have to regenerate the gui's python code with a command such as : pyuic4 -o axisGui.py axisGui.ui But it is no big deal, and could even be automatically done. And, in order to add functionality, users need to know how to write C++ code. That is untrue. Unless you want to create a new widget class, not a single line of C++ is needed. Would you really need to do so, Qt API is so well coded that it is a pleasure to code. I'm only just learning Qt, so I'm probably wrong. I've only played with C++, but each change to a .ui runs a post processor to generate a .h which needs to be compiled. Any change or additional Action requires the consuming class to add Slots. Can this be done at runtime? Or do you expect all Slots will already be present (a slot for each emc function)?

Re: [Emc-developers] Willing to contribute
My 2 cents... I'm new to emc. I chose emc for my lathe after using mach for my mill, mainly for the threading support, but also because it was open source. I was very impressed with the internal architecture of emc, and how easy it was to build and a configure a system with components, pins and links (I'm a programmer). I was expecting the UI to be same, being able to build the UI by add the visual components that I needed. Unfortunately, the emc UI isn't there yet. I'd love to see a mach like interface, where a complete UI can be built by dragging and dropping components, and linking them with script. Is this a lot of work? Probably, but once the framework is designed and implemented, anyone can add components. I also like the idea of using an emrsh like layer in the UI - I use X over the network, so I can code inside the house, not in my cold workshop, but the updates, especially the 3D, are terribly slow. At the moment I'm working on a visual pendant configuring application (configure any USB HID device to be a pendant in emc) so I can use my home made pendant, and also to learn Qt. After that I was looking at a visual Hal configuring application, so I can test out more of Qt's features. I'm definitely interested in contributing if you need help.

[Emc-developers] string type hal pin?
I have a USB device I want to use as a pendant which has an LCD display. I'm OK with writing the USB code to program it, I'm just unsure how I can integrate it with emc to provide useful outputs. I'm building yet another joystick type hal component. It works at a lower level allowing access to all HID items - it should work with the ShuttlePro. Initially I was thinking my hal component would have a pin that was a string input, but hal doesn't support that. Is there another standard way to communicate strings? I'm not sure if I need to expose that interface to other hal components. My component will live in user space. Maybe I just need to be to talk to axis. Any thoughts? -- Register Now for Creativity and Technology (CaT), June 3rd, NYC. CaT is a gathering of tech-side developers brand creativity professionals.
