Im lost with this one. I need help.

PlaneLinePoint
Hello, so I have been using pc-dmis for about a year now. I know how to align a part so I know its not that. This is how my probe looks after A1 manual first alignment. I tried to reset product as well and I still get this problem. Starting fresh, I load a model, and the xyz are all flat meaning if I use vector points to interrogate it, the x, y z never move if I were to click on other locations, so I know I don't have to flatten the model, because as we all know sometimes its origins are not square with the model, but this is not the case.

Here is the problem though, when I do 3 2 1 level rotate origin alignment and then after A1 this is how the probe looks on the screen, before alignment A1 if I were to click on CTRL+F for auto feature vector point the probe looks as it should look, straight down, but after a1 code if I press CTRL+F and put a vector point, this is how the screen looks. After A1 if I click on x y z surfaces with vector points, they are all 0, meaning my alignment is how I want it, but again this is how my probe looks, and im unable to actually align the part. What is this? I tried rebooting, powering the machine on and off and whatever I do, after A1 my probe goes like this on the screen / as you can see from the screenshot.

After A1 I would turn on dcc mode and adjust my clear plane using f10, but I cant even get passed A1 which is odd because usually the machine knows where the part is, but if I do auto feature after dcc it will show on the screen going with this angle in the screenshot below and it ends up missing the part. Guy who is running the part says its not the part and that he checked with indicator. Im using flat surfaces for the A1 manual alignment, but again after I do ctrl+alt+a for alignment utilities and do my 321 and press ok, and press ctrl+f after A1 code, my probe goes from straight down to how it looks in the picture below.

Any help would be greatly appreciated.

  • From the information you have provided one thing I would advise is changing the constructed line fron a 3D to 2D as 3D lines can cause issues in alignments.
  • I don't think it's been stated, but we need to see more code. Stuck out tongue closed eyes

    I second UKCMM with the 3D to 2D line.

    That is good to check vectors to avoid any abnormal. So you think A1 has an issue... then play on it..

    B4 play, always remember to keep your copy.

    I vote on UKCMM

  • More code is good.

    Double check your setup is rigid on the CMM, and double check dudes part is actually good with an indicator (maybe while on your CMM)
  • Is this with a CAD model or without? Are you teaching the program "live" on the machine or are you programming it offline first and then executing? As others have already requested, please post more of your code. We need to see all of the features and all of the alignment steps that you have followed so that we can help you troubleshoot.
  • Try changing the alignment too..... one thing is most important, when making any alignment, remember about LEVEL - ROTATE-3xORIGIN. You must follow this order. If this rule is not followed, sometimes our alignment will not be as we would like it to be. .........You have LEVEL-ORIGIN-ROTATE-ORIGIN-ORIGIN.

  • Thanks for your reply, everyone. I'm feeling a bit embarrassed about this. It was my mistake, I was attempting to save time by copying and pasting some code from a previous rev I had created into the new rev. I could have used the previous rev and ran it like that but wanted to have the new model because of differences which we were not probing anyways. Despite the new rev model, the locations remained the same for what I was checking prior. I imported the new model into a new program, applied the same transformations as the previous one, and pasted some of the code from the previous rev into the new program. Visually, it seemed like it would work because when I would press F9 on the pasted code it lined up with the new model. I figured it out when I created a new vector point which was not created prior and it would find the part for that one but none of the copied vector points, I thought it would update after alignment 1 telling where it was, guess that was not the case. Part is good and the nightmare is over, learned a lot, no more shortcuts. ​
