[Emc-users] Hal question
Hi. What i need to do is to enable joystick jog only when button1 is pressed,to avoid accidental movements. I think to do it with an if statement, but don't know how to implement into hal commands. I think i cannot use and2, because button is a bit, while value from the stick is a float. The only way that comes to my mind is to use mult2, using as inputs the float value from the stick, multiplied by 0 or 1 if the button is pressed or not. Can you tell me what's the right way to do it? Thanks, Davide. -- Learn Windows Azure Live! Tuesday, Dec 13, 2011 Microsoft is holding a special Learn Windows Azure training event for developers.

[Emc-users] recompile puma560gui
Hallo, I would like to change puma560gui.py for the custom of the simulation of my robot. I go in emc2-dev/src/hal/user_comps/vismach and edit the file puma560gui.py. I save it and recompile with this procedure: cd emc2-dev/src ./autogen.sh ./configure make sudo make setuid but the changes that I've made there aren't. The file is always the same. I have noticed that there is another puma560gui file in usr/bin. So NOT in the directory emc2-dev. How I can edit puma560gui correctly?? -- Learn Windows Azure Live!

Re: [Emc-users] recompile puma560gui
One way to save confusion might be to change the name of one of the
files, put your edits in there, then use the new name in the HAL file.
I tried how you have suggest me. I change a name of a file in armdroid. But
when I run emc2 I have these error:
- execv(armdroid): No such file or directory
- armdroid exited without becoming ready
What these mean? I have notice that there is this submakefile in the directory

Some of these are mentioned in the G Code Reference manual. Have I missed any? Would it be useful to anybody else if I made a wiki page listing all known parameters, how they are defined and which functions make use of them, and whether they are writeable or readonly? Also, is there any way for hal components or logic to use or change any of these parameters?

I have never been able to get consistent results from a tool change operation. The problem that may be the cause of the inconsistency? I do not have TOOL_TABLE = tooltable.tbl such a line in my current .ini file, and may not have one in any of them! The save operation that allows a new profile, like my-mill-test, to be written, apparently does not define that, ever. Could this be construed as a bug? I certainly was not aware that a tool could be described in that much detail so it will take me a bit to wrap my remaining wet ram around it, and to get something entered that might make sense to emc. Unforch, my toolholders are #2 morse collets in that teeny mill, so the working lengths, unless measured after tightening the draw bolt each time, are completely random. And that brings up a question?: Do we have a function that could be written into the gcode after a tool change command that would probe the tool like G38.2 does and record that length offset and use it till the next run restart, or till the next tool change? That would open the door to my being able to switch cutting mills mid-job, and would expand the view of what I can do considerably. Is there a link that allows this whole thing to be downloaded as a pdf? Ahh, I think I found them, but broken into user, hal etc. My dead tree 'manual' stuff in the shop is about a year old likely out of date as I have been letting the package manager update my emc install each time a new release is built.

A trim router such as the Bosch Colt can be fitted with collets by Precise Bits (http://www.precisebits.com/gateways/ColletsNutsHome.htm).

Re: [Emc-users] small spindle
It all depends on your system and what you want to do. I have found a Harbor Freight (cheep Chinese) laminate router an inexpensive solution for my small (400x400x100mm) gantry router. At $20 to $30 (depending on sales) it is cheap enough to have a spare and replace if a problem. Cheap enough to bury one every year or two. I do mostly small things in wood ( 100x100x5). Some Al, plastic and soapstone. The lack of frame rigidity is the primary source of errors. I have not found an 1/8 collet for it, but a 1/4 to 1/8 collet sleeve seems to work ok. Others have found other small routers or die grinders a solution. I would consider a die grinder if I were changing the mounting design. standard 1/8 collets are available for these.If I were doing a lot more work with it I would also consider a quieter, more small expensive router. The Harbor Freight one is noisy for its size. Craig Enumclaw, WA USA Just North of Mt. Raineer.

These have centrifugal collets for 1/8 tools, but are designed for drilling, not routing. They can be run off a standard VFD with additional inductors between VFD and the motor. A repair show charges $6000 of a rebuild, so they must be pretty pricey. These will go to 80,000 RPM or so, but I can only do 24K with a VFD that goes to 400 Hz. I also got a Rockwell/Precise ball-bearing spindle, but it needs TWO-phase power, so a standard VFD can't be used, at least without a Scott-Tee transformer. It will go to 45K RPM, and is 3/4 Hp.

Real hollow-shaft encoders with bearings are quite expensive, BEI and Danaher come to mind. The Kit encoders have a free-floating wheel that is supported by a shaft on the motor or machine, and have no bearings. They are much cheaper due to this.

I wonder if this is related to the lag you refer to. How and why does this present itself in these encoders? How would be see it? Yes, that is EXACTLY the kind of problem I saw. This encoder is highly interpolated, so it has a tracking counter that is incremented or decremented by an estimate of the current velocity. If you don't do these computations correctly, there is a lag in responding to changes in velocity. As far as I can tell, the interpolator in such devices as the Analog Devices AD2S1200 has a really fine 2nd or 3rd order filter to make this work well. Obviously, CUI did not go to the trouble of such mathematics. After never being happy with these encoders and having a bit of customer feedback, I decided to compare to a standard HP optical encoder (with no interpolation.) So, I put the optical encoder on the other end of the motor, and fed both to encoder inputs on my PWM controller board. Most useful was to plot velocity derived from both encoders at the same time. This comes up often enough, I have the plots permanently on my web site. See http://pico-systems.com/images/compare_encoder2.png The red trace is the CUI encoder, which was controlling the motor (badly). The white trace is the HP encoder. Both are providing 4000 counts/rev. You can clearly see the velocity peaks of the CUI encoder are higher, and if you look closely at the slopes, you can see the CUI is slow to react to velocity changes, and then has to overshoot significantly so the position can catch up. This of course accounts for the bad servo behavior. As the Halscope is set for 20 ms/div, the velocity lag is easily 3-5 ms in duration! If you have a plain optical encoder handy, you could easily set up the same arrangement to compare the encoders.
