metric sae conversions
« on: March 28, 2007, 08:08:50 AM »
I prefer to use inches as my standard but my Cad program is Chinese version and all postprocessors within it are all in mm.  I forget what page it is on but there is a button that allows you to toggle from mm and inches which I use to run my mm codes on mach which is by default in inches. Also I've locked my dro's to read in inches. My problem is this while mach is is set to read mm and the dros are locked to inches the dros will show mm's while jogging in steps which are in inches. Example Dro's are locked to sae Mach is set to read metric code and when I open jog with the tab key and set to jog in steps of .010 inches (or any other increment) it will jog .010 but the dro's will show  a movement of .0004 which is the metric equivelent. Any suggestions??  B. Ender

Hey B.Ender,
     In the top left hand corner of the general config page, uncheck the box that says lock dros to set up units. To toggel between mm and inch, go to you settings page. Should see a button that says units Alt-U, that will change you back and forth. Also, your g-code can change your units as well. G 20 is inch and G 21 is mm.

Hey brett,
 I want the dros' to be locked especially when I am running a file in mm. That way I can identify problems easier in sae.
 I already toggle back and forth on the settings page.
 What I am asking is why does the dro's still read in mm when jogging in steps even though they are locked in sae and I am jogging in sae?? I do not want to have to toggle back to sae in the setting page just to jog and then back to mm when running the code. Trying to save time.

Hey Brandy,
    If I lock my dro's in set up units, which is inches, they read inches even if I choose metric on the settings page. Is that what you are wanting yours to do?

Brett,
 Yes this is precisly what I want. However hit the tab key toggle the jog control from continous to step. Then jog your machine watching the dro's. Even though they are locked in sae and you are stepping in sae they will show movements in metric when set to metric in the settings page.   Brandy

CAD systems usually work in units, its the post that sets inches or mm's, if you look in the posts you will be able to set them to inches.

Attach a post for us to look at.

Graham,
 My cad program is a chinese version and all the included post processors within it are all metric. Also there is no included post for Mach so I use one that I picked at random and for the most part still works for me. Are you saying that this processor can be tweeked to produce sae code??

 Irregardless of units used I believe the DRO's should still read in the units you have them locked to. As stated in earlier posts they do not do this when jogging in step mode.

Hey Brandy,

On my system, my DROs are reading in inches, only the moves are a metric amount. In other words, if I give a move of 1.0000 while in step, settings set to mm and DROs locked in inches, it moves .0393 inches. That would be correct. The move is 1 mm which = .0393 inches. I think that what you want is for everything to be mm only the step distances would be in inches and the DROs would allways read inches. I don't think that would be possible. I have sent you a personal message.

OK,  imperial is inches,

attach your post and lets have a look at how it is structured, then we may be able to modify it.

Hi Brandy,

Brett sent me your post, its a 2 part post system. Let me have your email address and I will tell you what we need to do to try and get you inches.
