In an attempt to create a new layer called "Dimensions" all I did was end up with a default layer called "Di" which now loads up with any new file opened. Any ideas on how to rename this to "default"?
I tried the properties>Layers but the "Di" layer is not listed.

Thanks much
Ken

Ken,
To change your default layer:
Make sure that OneCNC is not runing.
1) open windows explorer and get to the file that onecnc settings are in,Something like (onecnc-xp/mill expert/setting/users)
2) in the file you just got to above there will be a folder named default or (a user name IE: some name you set up) open this folder up.
3)Open the file name (setting.ini) This will open into it's own window, look for this line in the file (defaultlayer= ) it's about 8 to 10 lines down, then edit the line to say (defaultlayer=default) or anything you want to be your default layer name IE: 0 or one or first or Ken's stuff.
4) at the top of the file window in the title bar select (file/save) then close the file and all the other windows you have open and your done.;)

you can do this for any user accounts you have set up.

That took care of it Ward,

Thanks for the help.

Hi Ward,
in looking over your examples again I noticed you seem to prefer working from the bottom side of the X,Y,Z axis, is there a reason for this over on top or centered in the axis?. Any one else have a opinion as I have not developed any particular habit on this as yet.

Your examples have been a big help, got the piston grooves down pat now but OncCNC bombed out on me before I was able to save it. As soon as HuFlungDung get back and I see what dual monitor video card he is using I am going to get another card. My laboring CPU processor is another issue.


Thanks
Ken

Ken,
I am self taught and when I first started to do this kind of work I didn't know that the "rest" of the world uses the bottom/left corner as "their" zero or start point. I guess you could say I didn't pick up someone else's habits, good or bad.

I figured that 90 % of the part in the world (at least in a job shop) would be held in a vise to be machined, so with that in mind I looked at a vice and noticed that the back jaw in normally stationary. So I figured that I would make that side (the back side) of my parts Y zero, that way if I was using material blanks that varied a small amount my zero would not be "moving" around all the time.

So it was natural to use the top/right corner as my "zero", that way x, y and z cordinates would all be negative numbers.

The way the "rest" do it x and y are pos and z is neg, as far as the machine code goes.

I do use the center of a part as zero if the part is round. It helps when drawing toolpaths, ect.

It really is a matter of what you get used to and are comfortable with.

As far as the cpu I have run OneCNC on a PII 350 but it is not very efficient. I now use a PIII 1.0 gig and a P4 1.8 gig both with good luck. Also you really need 512 mb ram or more ( more is better)

If I recall HU is using an ATI 9000 series card, but Nvidia and Maxtor all make dual mon cards.

You may want to call Mike or Lew at OneCNC as I know they just last week set up a system with a dual monitor.

Hi Guys (and gals if there are any here :) )

I missed you all while I was away, but now I'm back and ready to rip. My wife and I had a really good time out on Vancouver Island. We also made a circuit of a few relatives on the way out, "killing many birds with one stone", so to speak. :D

Anyway, in response to the question about dual monitor video cards, there are likely many that you could choose from. I seldom buy top of the line hardware when it is first released because I feel it is a poor investment, but if you buy 2nd or 3rd older generation, that seems to be a good balance of dollars with functionality.

I am also a bit of a FPS gamer (FPS="first person shooter" for those who are not initiated), so I always appreciate a video card that can run a fancy game at a decent framerate.

Since ATI seems to be really kicking butt with new fast video and excellent video driver support, it was a no-brainer to go with an ATI card. I picked the 128meg R9500Pro. This was about $185USD back when I bought one off an Ebay seller, but I don't want to know what you can get them for now :D

The real top of the line is R9700 or R9800 now, but they are still quite expensive. I'll maybe look at getting one of these eventually, after the prices have tumbled a bit more.

But a lesser card will also serve, although I can notice the difference in redraw speed sometimes. I have a second computer with an ATI Radeon 7000 series, which is now quite an ancient card, but it had dual monitor support.

There is a difference between the ways that the older dual monitor cards run with windows, compared to the newer ones. The R7000 requires Hydravision software to divide your screen properly, and to recall your favourite settings for window positions for a particular app. Your desktop actually gets stretched across the two monitors, and most apps would otherwise run in this stretched mode. This is annoying because it puts the center of your window right at the left and right edges of your adjacent monitors. Hence, Hydravision is used to remember your resized windows, which you drag around and make fit your monitors properly.

The newer cards, like the R9500, behave a bit differently, and automatically direct the app to open on one monitor or the other, no additional software required. In fact, Hydravision will not work, and will give you an error if you attempt to use it in such instances.

HU,

From my personal experience communicating with you via email at what seems to be all hours of the day and night, when do you even POSSIBLY have time for video games??????????

By the way, my wife and I visitied Victoria several years back and really enjoyed it. Just beautiful.

Mark Linder

Thank you for the advice on a video card Hu, I will look into them .
