Tesastar-M Problem

[[email protected]]

Here is an interesting one.
I have a Global Advantage 7.5.7 and I'm running v.4.2. The head is a TesaStar-M with a SM25 scanning probe.
Periodically the knuckle will go limp and throw up an Emergency Error. It acts the same way it does if you crash into something but the probe is just sitting there doing nothing.

it has never taken even a mild bump

Do you have an HCU (Hand Control Unit)? How do you recover from this?

yes we have a hand controll unit. I just turn the machine back on and clear the error message and it is fine. It checks everything accurately and acts fine when it is in motion. It only does this when it isn't moving.

This is a relatively new head on the market as far as I know. You may have to contact B&S/Hexagon about it. It may be an air pressure issue, but I sort of doubt it. You could have a faulty head. Please let me know, I am trying to get approval to buy a new machine and I was intending to get this head on it, but if it has problems I may stick with Renishaw.

Air, that's what I was thinking. I have the same Probe. What I have been experiencing is that sometimes it stops taking points in a program. And I mean during a manual alignment hits. Right in the middle of taking them, nothing? So I shut it down and have to chager angles and re-start the program.

Thanks for your help. I appreciate it. I will let you know what I find out.

TesaStar-M Head

Overall I like the Tesa head. I like the 5 degree increment, it adds a little more versatility. The only real complaint I have is the Renishaw converter, it's over 30mm long. That takes 30mm from the my travel. Although, it hasn't caused much trouble yet. So far I would recomend it, but it would be nice if they could shorten the converter some.

by the way. It seemed that the air was the problem. Thank you

Glad to see you got it. I really must know how much e-mail you get.

Suprisingly not that much. It is just a trash email account anyway. I use it sparingly
