probe storing problem


Recommended Posts

---

First time I've ever seen something like that. I would probably just keep taking off components one by one to try and isolate the problem child. One stylus off, other stylus off, knuckle off, etc. 

If it keeps alarming when completely dissasembled, maybe it has something to do with the qualification?

Very shocked that changing the adapter plate and rack port didn't help.

Do you have another machine you could try this on?  Rule out the probe head if it is a weight or balance issue? 

 

I had this issue once but it was specific to the holder location.  It ended up being that the screw somehow backed out that held in the circular clocking tab that is under the bellow of the holder.

I do not have it activated on my machine.  BTW, the ID chip can be switched on or off on VAST-XXT, too.  Typically, it only comes into play when loading a stylus system manually or via cnc change. It ensures that you have loaded the correct stylus system.   

I am able to pick up this stylus system, just can't drop it off.

I agree that its odd that changing adaptor plates or probe holders didn't help.

I don't think balance is your issue.  I use one stylus system that is way more out of balance than that one, and it still picks up and drops off fine.

Gremlins or Voodoo is the only logical explanation here.

Likely not your issue, but I had encountered a probe change issue in the past as well. Zeiss techs came out and thought it was likely a short in the cabling. I found out we had water/oil getting into the machine that was causing the limit switch to activate randomly during probe changes (always when dropping off). In my case, the probes/bays were random so trying to pinpoint the issue took some time. Ended up deep cleaning the bowls, replacing the filters and adding additional filtration to the incoming air line to resolve the problem.

Those are rub marks from the holder. I usually get those on the most used stylus systems and adapter plates with rough anodize. I usually clean my plates twice a year to remove it. I had a similar issue with adapter plates not engaging or disengaging in a holder. Couple of things I did was change the name of the probe assembly and build it with just a single stylus in the Z direction. Then if it changed with no issues, modify it to be what I needed. The other thing I did was clean all the bays really well and polish the fins that guide the adapter plates in place. If none of these worked, I re-weighed and re-balanced the assembly to ensure it was as close to even on each side. Another thing to try is possibly put small extensions on the X+/X- directions to see if there is an angular issue preventing the change from happening.

Everything is official Zeiss gear.  I will take a look at plastic buildup, including on the other two adapter plates.  

This machine is not in a production environment and gets very light usage.  It is off more than it is on.

I'm going to focus on the balance though I've used unbalanced stylus systems in the part and never had an issue. I do try to use some kind of counterweight most of the time.  Everything I'm currently using is carbon fiber with the exception of the 3x58 stylus with the steel extensions. Maybe the steel extensions are too much weight in the -Y direction....   Any suggestions on how to balance a tool?

I also don't have any issues with the other probe with the extended +Y. I think the only 3 things left are the cleanliness, the balance or the new VAST-Gold, though I tech told me it couldn't be the sensor. And, the suggestions by Scott W.

Thanks to everyone for the feedback.

It seems that even when switched off, the ID chip system is never fully inactive. When I set up our new Conturas in 2023, they rejected  many of our existing (old) third-party plates, no mattter what I did. I have the ID chip set to off too, but it happened anyway. The only thing that helped was to isolate the two contact pads on the PCB by sticking two GOM reference marks on them. 🤣

The Device Activator is also for the active sensors like VAST Gold or VAST XT Gold, it gets updated every ~6 weeks on the portal and has new plate ID's included for the new created Adapter Plates.

When you buy new adapter plates there should always be a red sticker attached to the plate packaging which says to run the device activator.

 

Best Regards

Marcel
