Re: [Emc-users] scaling G code
Greetings A modal scaling code (G51?) is certainly useful and fairly easy to define in terms of its effect on X, Y, Z etc. coordinates submitted to the interpreter.

Re: [Emc-users] scaling G code
If you are going to do that, it shouldn't be a translation matrix; it should be a transform matrix. That would be a general affine transformation. That would provide translation, rotation, and skew. So, if your X and Y axes weren't exactly perpendicular, that could be corrected. We might want to require that Z be perpendicular to X and Y for a mill. It wouldn't make sense to drill holes where it was not. To me, the big implementation issue has to do with the display. Do you show the G code coordinates or the transformed value? Can the user at the interface (Axis or whatever) choose which one is displayed? In any event, the current transformation matrix should be stored as a series parameters (in the gcode sense). That way, it could be easily changed by G code. Slap a part on the table, probe a few points with a gcode subroutine which sets the origin and rotation (computing the transformation matrix), and you're off and running.

Re: [Emc-users] scaling G code
Here is a programming manual for Mit 300 seres controls, rotation stuff starts at page 184 of the PDF 172 of the scanned book. Its an old control but easy to use and it had a lot of options, and the manual is a free download. :) http://www.meau.com/functions/dms/getfile.asp?ID=0100010046090http://www.meau.com/functions/dms/getfile.asp?ID=0100010046090 In case that link to the PDF does not work here is the page, book BNP-A2943 should be second in the list. http://www.meau.com/eprise/main/sites/public/DOWNLOADS/-search_results?SType=3DocType=010SessionNum=UserID=Division=00010Opt1=Yessubmit1=SearchFamily=ManualType=0055 It does a fair job of describing the interactions of the rotation and workoffsets and other things.

I think that funny things happen to datums whatever option is chosen. Well, you have to define where these translations and rotations work from. Making the rotations around the translated (0,0,0) coordinate would make sense to put everything around the part's new origin.

[Emc-users] scaling G code
Alex, You are right of course. It's only the number that is important. I guess the default is 1.000. The units don't seem to change anything except the units displayed in TKEMC or whichever display you use. I set up an experimental stepper inch which scales correctly on my machine (input scale 4000). The dial indicator on the axis agreed exactly with the tkemc display. I then changed units from inch to .5 inch. The dial indicator only moved .5 inch for every inch on the tkemc display I then changed the units to .5 mm. The results were the same as when it was .5 inch. Apparently the actual movement of the axis is the result of the scaling factors in the axis sections multiplied by the value of the UNITs number in the trajectory section. Therefore I can change my inch setup to mm for instance by either leaving the scale for the axis at 4000 and changing units to .03937x or I can leave the units as one and change the scaling factor to 157.xxx (4000/25.4) the movement will be the same. I had read the manual several times before I started this thread and I have read it again several times in the last couple of days. Now that I know how the system works the manual seems to agree with what I now understand. It's amazing how smart other people get when you finally understand what they were saying all along. Bottom line... If I use my inch scaling (4000) and set units to .03937 and run chips it will cut it at full scale. If I change units to .019xx (.03937xxx divided by 2) the program will then cut chips at exactly one half the size of the original. Like Ray said yep By the way the 3D_chips.ngc file header calls for a 10 mm ball end mill whose diameter would be one tenth of the entire figure. That don't leave much room for detail!! I think it was probably supposed to be 1 mm. Sorry for the confusion and thanks very much for the help. Cecil the change as I implemented it, was primarely targeted at _not_ breaking old configs. So you can still safely use numerical values (even ones different from mm, inch, etc.) Regards, Alex - This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.

Re: [Emc-users] scaling G code
Hi Cecil Glad that we got that all figured out and you've got what you need going. The ball endmill called out in the chips.ngc program was intended to be able to handle all those deep cuts without breaking. The guys at Smithy cut a real, fairly nice version of chips by getting the original cad and running watermarks using Synergy. That way they were able to increase the resolution and at the same time use a smaller endmill. Last time I was there I tried to find the code they produced but the fellow that did it has moved on. Now fifw, it seems to me that it's time to modify the interpreter to allow for a modal scaling g-code. Rayh BTW you must be using full step drivers for a 4k input scale. If I remember, the official version used 16k and quarter steps. I know you said you'd built up your own system. Could you describe it a bit more for us. Pics on the wiki would be nice.

The ball endmill called out in the chips.ngc program was intended to be able to handle all those deep cuts without breaking. I noticed that when I scaled the endmill to be small enough to get any deatail it then had too short a working part to make the plunge and still cut all the way down. Thank god for plastic!! I thought about scaling the z axis to 1/3 of x and y and makeing one cut then rezeroing and rescaling to 2/3 for another then make a final pass at the same scale as x and y. That should make the passes doable with a standard end mill. I realize that this is just an exercise, but hands-on exercises almost always teach me something, sometimes something I didn't realize I needed to know. Now fifw, it seems to me that it's time to modify the interpreter to allow for a modal scaling g-code. Looks like it could be useful. BTW you must be using full step drivers for a 4k input scale. If I remember, the official version used 16k and quarter steps. I know you said you'd built up your own system. Could you describe it a bit more for us. Pics on the wiki would be nice. I am using an old DM 2 table top CNC mill that Paul Hamler found for me a few years ago. It is a sherline mill with steppers mounted in a big blue box with proprietary electronics and software. It uses the 5804 chip and is prsently set up for single steps and ballast resistor drive. I can do some trace cutting and rewiring on the cards and get more steps but I really need to trash the cards and go to a chopper drive. I disabled everything but the spindle speed control and the power supply, reconnected the axis driver cards to the power supply and routed the card's step and direction inputs to a newly installed parallel port connector. It's probably obvious that I am pretty much a hands-on type. I am an electronics engineer retired from the Nuclear power industry where I did instrumentation and control design. Where I worked engineers were not allowed to touch things so we had to spend hours or weeks meticulously designing and documenting and co-ordinating a project for someone else to do which we could have done in a few hours of hands-on work. In order to compensate for not being allowed to play with the toys at work, I have always kept a few electromechanical projects going at home. I have found EMC CNC to be an almost perfect diversion. It lets me play with computers, electronics and machines all at once and most importantly I don't really have to make anything but parts for my machines. My goal is to use the little machine to gain as much proficiency and knowledge as possible on this scale and then convert my Powermatic Millrite mill to CNC.

[Emc-users] scaling G code
Chips is supposed to run on approximately 4 x 4 inch block which is too big for a sherline based machine. I got it to run on a 2.5 by 2.5 inch block by using stepper_mm.ini and changing the input scale on all the axes from 200 to 50. I tried changing the output scale from 1 to other values but it didn't seem to have any effect!!! I couldn't figure out how to scale it using the units in the trajectory section. The older versions of EMC used a numeric value for units ( .0397x or 1) in the trajectory section of the .ini. I could just change the value and presto! new scale!! The new version doesn't have a numerical value... just mm, inch, or cm. I assume that the terms are defined somewhere in numerical values. But it won't be the first time I made a wrong assumption. Could it be that the trajectory units don't do anything and the input scale on each axis determines how much the axis really moves?? If I wanted to rescale a part on one or more axes without messing with the G-code is the input scale in the ini the way to go or is there a better way?
