Optical Calibration Standard targets seem out of sequence - vision probe calibration

I'm not sure what details are really relevant here, because I'm pretty new to this. Let me start with what I think are the relevant details behind the error message, and then later fill in what may not be useful Slight smile
Machine: Tesa Visio 300 DCC
PCDMIS Version 2010 R2 Pro Disappointed )(Cad seems really nice!)
Other Symptoms: PCDMIS says it cannot zoom, that I need to recalibrate
Calibration Slide: Just bought the quite expensive calibration slide direct from hexagon PN 25-1234-02
FrameGrabber: IDS Falcon
Windows 10 x64

So here's what I tried. I went into the probe setup, clicked measure. I tried calibrate optical center, but when I click the ++ button PCDMIS happily gives me the message "Attempted to move outside calibrated range- Ple re-calibrate optics." … Well, I thought that's what I was trying to do!
Fine, I manually moved the zoom....maybe not the best thing for accuracy....and did the center calibration. It was fairly close.
I then go to calibrate optics. The only option for calibration standard not disabled is "Hexagon Metrology slide", which, as far as I know, is what I bought.
Under the calibrate group I selected "Pixel Size" only (KISS to begin with)
Under settings Illumination is "Bottom Light"
Focus Lens N.A. is 0.00 and Range is 1.856 (Not really sure what those are for, so I didn't touch them)
I hit calibrate
The light level changes a bit, and it goes through the 3 popups about being aligned, cleaned, etc. I read the model number for the slide off the video of the machine, so I'm fairly confident its face up Slight smile
I let it do its focus. I've tried this step all around the slide. Nothing seems to make a difference there...
It then asks to center the rectangular targets. I assume this is the rectangles in rectangles...so I do....
It then adjusts light again, and draws some autoline boxes around the outermost rectangle. Then it complains with the message in the topic. I'll include a screenshot from the calibration to make sure I'm not doing something incredibly stupid. Also including the part number in the view in case I'm not supposed to be able to read it normally Slight smile

I suspect I have more than one problem....

  • So, the manual didn't really help with the issue, but it did get me thinking about the error message. It says out of sequence, as if it thinks it moved, despite seeing no motion. What motion? Its gotta be zoom. PC-DMIS won't let me test zoom though. I do have a program from the QC5000 controller card. Well, that program also won't zoom, which means I'm likely on to something.

    I see that for zoom in the qc5000 program, it has options for "Legacy", "Open Loop Stepper", "Closed Loop Servo", and "Closed Loop Stepper". Looking at the zoom mechanism on the machine itself, it sure looks like there is some sort of position encoder, though I couldn't tell you what sort (so I assume closed loop), and I'm not removing it to find out! (Don't need to have to calibrate that too!) Seeing that stepper is an option, I decided to have a closer look at the motor. At first, when I moved it manually, I didn't feel any cogging, so I discounted it being a stepper motor, however, this time, I noticed the sound. It sounds like a stepper through a gearbox. So, what the heck, I try setting it to stepper. Suddenly, its holding position. In the open loop mode it will try to home, though it doesn't seem to do a good job.

    So I'm fairly certain this is a stepper motor. Unfortunately, that's where my progress ends. I don't have a clue what the settings are supposed to be. I double checked the Tesa Directory in the Program Files and the cnc.ini file still shows servo for the zoom axis. I verified axis 4 was zoom by setting it to stepper in the PC-DMIS directory, and fired up PC-DMIS, which then powered the stepper. Regardless of that, none of the axes were marked as stepper. So I'm fairly certain someone at the company who owned this machine when it got the suspected surge, or the used machinery dealer overwrote the original settings. Worse, I found tools to open the ghost image dell distributed as a restore disk (let me tell you, finding ghostexplorer from a site that isn't sketchy is impossible! virustotal said the one I found was clean). No Tesa directory there. No other discs I received have it either, so I suspect I'm missing a disc. So unless someone has a Visio 300 dcc they're willing to send me some settings from, I think I'm out of luck without some help from hexagon. If anyone wants to help without responding publicly, an email address I check sometimes (not my main one, not going to post that here) is corrysjunk at gmail dot com (Still don't want that one to be picked up by basic web scrapers, though that pattern is probably programmed in most bots as well...)

    Otherwise, I guess I'll see what I can get from Hexagon tomorrow. Who knows, maybe there is another CD that I can order as a "part" Slight smile
