Re: [Emc-users] comp
Thank you Alex, and you are right. When I install the EMC2-dev package, there is an error: Error: Dependency is not satisfiable: emc2. What does the dependecy mean? And where can I find the package to download and install ? Thanks again! Regards! Yang 在2009-01-14，Alex Joni alex.j...@robcon.ro 写道： apt-get install is a command to install a package from the internet. If you have no internet available on you rPC then you need to download the package from: http://www.linuxcnc.org/hardy/dists/hardy/emc2.2/binary-i386/emc2-dev_2.2.8_i386.deb you can then install the package using: sudo dpki -i package You'll probably get errors if there are dependencies needed, so you need to go and find those packages, download and install them by hand.

[Emc-users] Parallel Port Signals
Afternoon All, This is my first EMC Users post (first mailing list in a while actually), so please be gentle with any etiquette misdemeanors ! I'm just beginning to put together a design for a hobby CNC machine, with my own driver board electronics - glutton for punishment really. Looking around, EMC seems to be the way to go in terms of controller software - as a GNU/Linux user, because this hobby project is on a budget, and because it looks to be nicely featured and extensible. So, my question for the time being is, are the parallel port signals (ie. the waveform/timing diagrams) documented anywhere ? For instance, are the axis step signals sent as pulses (ie. step the motor once per low-high transition), or are they flat (ie. keep stepping the motor until the signal goes low) ? I've seen the StepConf documentation - which is the closest I've found - but that doesn't really explain a lot (it's more end-user oriented). I'm sure I will have more questions, especially around timing, so if there is a source on the 'net with this sort of low-level detail that I haven't seen yet, I'd appreciate a link. It's either that or you're going to get sick of my constant e-mails pretty quickly...! Thanks in advance.

You don't strictly NEED to know how HAL works, but if you are at all interested in a low-level understanding, I strongly recommend at least reading and preferably actually doing the tutorial: http://www.linuxcnc.org/docview/html//hal_tutorial.html Regards, John Kasunich -- This SF.net email is sponsored by: SourcForge Community SourceForge wants to tell your story. http://p.sf.net/sfu/sf-spreadtheword ___ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users

Re: [Emc-users] Parallel Port Signals
Peter, Welcome. If you are using the AXIS display option - as is default on the Live CD, you can get an idea of the output waveforms by using the built-in oscilloscope function. If you look in the HAL tutorial that John points to, you will find instructions on how to use it. Basically though, any 'pin' or point in the control chain may be used as an input signal for the multi-channel scope and this is a very useful feature to learn what is happening in EMC2 and to trouble-shoot. -- Best wishes, Ian Ian W.

You don't need to be using AXIS to use the scope. AXIS simply provides a convenient menu bar entry to invoke the halscope. You can use halscope ANYTIME as long as HAL (or EMC2, which uses HAL) is running, regardless of what GUI you are using. From the command line: halscope. At a halcmd prompt or even within a hal file: loadusr halscope. You can also make a desktop icon or menu item to start halscope, but I'm not sure exactly what the steps are to do that. I do most things with the command line, and if I need to make an icon or something, I just muddle through.

I don't know if all the low level stuff is in the PDF manual, but you should find it all on the linuxcnc.org website: http://www.linuxcnc.org/docview/html/ HAL tutorial here: http://www.linuxcnc.org/docview/html//hal_tutorial.html (note: some screenshots are a bit out of date) For instance, are the axis step signals sent as pulses (ie. step the motor once per low-high transition), or are they flat (ie. keep stepping the motor until the signal goes low) ? I've seen the StepConf documentation - which is the closest I've found - but that doesn't really explain a lot (it's more end-user oriented). Note that you have options that are not step/dir. You can do PWM+direction or up/down PWM for example. Making a driver for a (smallish) servo may be easier than a stepper, since you need half the electronics (one H-bridge instead of two). There is the added complexity of encoders, but those are pretty simple to hook up - you just need more I/Os. If you decide you need some type of output that EMC2 doesn't already have, you can write a component to generate it. EMC2 is separated into several layers, and the motion controller doesn't care how the lower levels get the motors to move. You can use PWM on one axis, step/dir on another, and analog on another, and the motion controller will still be happy (as long as all the motors keep up). I'm sure I will have more questions, especially around timing, so if there is a source on the 'net with this sort of low-level detail that I haven't seen yet, I'd appreciate a link.

If you use hal_input (check the wiki page or man hal_input for necessary udev setup), then you should have access to pretty much everything on the device (as hal_bit inputs/outputs for buttons/lights, hal_s32 and/or hal_float for analog sticks). And of course, has anyone written a connector file so that it can be used as a hand pendant with later emc's? My bet is that nobody has written such a file, since you're the first person I've heard of with this particular device. (Unless it's the same as the Logitech everyone talks about, under a different name). It looks like this device may be like my Belkin Nostromo, in that it presents more than one input device (I see input5 and input0 listed in your dmesg dump) to the input subsystem. If this is the case you'll need the version of hal_input in TRUNK, which allows you to use more than one device with the same name spec. - Steve As you will see, Stuart offered a file which I've pulled, but its too cold to go play for a few days.

[Emc-users] [OT] seeking info on Gorton MasterMil 1-22 powerfeed
Gentle persons: This is a long shot, but your collective knowledge seems inexhaustible. A long-time (ca. 35 years and counting) friend has gone and bought himself a Gorton MasterMil 1-22 vertical mill that he estimates was manufactured in the 1960s. He tells me it's in very good mechanical condition (but he's on the wrong coast so I've seen only pictures). He's already making parts with it manually. I hope to convince him to consider at least a 2-axis CNC conversion using EMC2 once he gets settled with it, but he's determined to restore its original powerfeed first. The infinitely variable powerfeed on this beast was an option-at-purchase called Dyna Drive that for his model is vacuum tube-driven. The electronics appear to be kaput. Web searches have coughed up scans of the operator, technical, and parts manuals for this model mill, but he has been luckless so far in finding any technical details about the optional Dyna Drive. If anyone has any hints, please email me directly so we don't clog up the list.

Re: [Emc-users] Motherboard recommendation, WIKI seems not up, to date
Gentle persons: Thomas Kaiser wrote: After I saw the entry with the Intel D945GCLF2 in the wiki, I decided to buy the same one. Unfortunately, this board was not available in my local shop. But the D945GCLF was there (same board with only a one core Atom processor). So, I took this one and it looks not so bad: Thanks, Thomas. I read some of the Intel documentation of the Atom processor family after Eric posted his nice numbers on the Wiki. There's fairly bewildering and evolving specifications of a bunch of chips under Atom and the differences are not just single- vs dual-core. So far I know about the Atom 200 series (single-core) and the Atom 300 series (dual-core) targeting desktops, the Atom N27x series (single-core) targeting laptops, and the Atom Z5xx series (single-core) apparently targeting so-called Mobile-Internet-Devices (MIDs). Of course, there are also different speeds available and there are two different 945 chipsets supporting the Atom processors so far. I'm not savvy enough to be able to infer from the Intel documentation how the specializations built into these various processor series and chipsets will affect EMC2 performance. I confess I got uneasy as I read about the complex interplay of software-selectable power states and clock speeds that has been made available to lower the total dissipated power (TDP) during operation and increase battery life. It'll be interesting to see what folks discover as they explore different board/chipset/cpu combos. Eric's and Thomas' data are certainly encouraging while at the same time showing real differences. As ever, be specific to be terrific when reporting results.

[Emc-users] Successful Emc2 conversion (happy dance...)
Emc2 community, I finally produced my first part on my new Kasuga/Emc2 (Mesa 5i20/7i33) knee mill conversion. I am very happy with the results!

The answer is that I don't have an servo/encoder on the knee - even though it is motorized, so all of my Z level tool length adjustments that are too great to be automatically compensated for in the G43H- commands, require me to stop the program (usually at the next tool change), raise or lower the knee, insert the next tool, and do a G43H1 touchoff, and just continue with M6T1 / G43H1 for all the remaining tools.

I set up the demo job at CNC workshop last year with the reference tool being the longest and everything else shorter (negative offset). In EMC2.3/AXIS you will be able to use touch off to set tool lengths instead of having to edit the tool table. It's super easy to use. Limited quill travel is always a pain.

Chris Radek ch...@... writes: snip Not true - tool lengths can be positive or negative. I set up the demo job at CNC workshop last year with the reference tool being the longest and everything else shorter (negative offset). In EMC2.3/AXIS you will be able to use touch off to set tool lengths instead of having to edit the tool table. It's super easy to use. Limited quill travel is always a pain. If you can motorize the knee and make it the W axis, you could use it for tool length offset! Ok then, my life just got easier. Don't know how I got it (positive integer) wrong. I have been salivating re: Emc2.3/AXIS and the tool specific touch-off with auto offset table updating. Thanks for that, Chris. I have a linear scale that is the perfect length for the knee. There is a 3hp 3 phase traction motor that drives the knee thru a differential gearbox, powered by a dedicated Danfoss VFD. The Danfoss has a full featured PID loop and can respond quickly to a pulse reference - this might be possible.

Tom ok, you move the knee fwiw something we used to do on the quill may be of help we'd slit a piece of conduit grind it to length and put it between the Bport quill nut and the end of the slot the nut rides in this gives you a fast mechanical offset something like this slotted tube may work on the knee screw raise knee way up insert spacer drop knee onto spacer raise knee remove spacer you get 2 known positions from an axis w/o a readout :) (hmm or more with a set of spacers) tomp Tom wrote: tomp tomp-...@... writes: interesting idea about short stroke but (appartently) longer manual backslide do you go from some stop to another or end of stroke to end of stroke for the 2 sets? thanks tomp Tomp, I think what you are asking is if I have the knee set up as a sort of auxiliary Z axis. The answer is that I don't have an servo/encoder on the knee - even though it is motorized, so all of my Z level tool length adjustments that are too great to be automatically compensated for in the G43H- commands, require me to stop the program (usually at the next tool change), raise or lower the knee, insert the next tool, and do a G43H1 touchoff, and just continue with M6T1 / G43H1 for all the remaining tools. Tedious, but works.
