Change Axis

[tc1656]

Recently started new job and the XYZ are all going backwards to me. How do you change them?

The machine interface setup, axis are grayed out...?

As in they are backwards on the CMM ? Left is negative X, right is poisitive X, Away from you is Positive Y ..... or you are backwards ?

Im setting at the back of the machine. I am use to turn control knob to the left to go down and it goes up. I can reverse the Job box and live with the X and Y but the Z is not good and setting me up for crashes.

[Schrocknroll]

I'm pretty sure the direction the CMM goes when you twist the knob is wired into the jog box. Is that a Wenzel machine by chance? I ran a Wenzel a while back and it behaved in that manner.

Depending on the jog box (and the CMM), it might be possible to reconfigure the direction the machine will move, check with your local Hexagon service rep. But be careful with that, if anyone else is also using the machine. They're probably used to it, as it is!

Don't try to change the axes in the Setup dialog, or in Settings Editor - that would invalidate all existing part programs (if I have understood it correctly)!

Its a DEA Alpha 2.0.
The guy before me ran it and just got use to it. I'm the lonesome duck in the water here.
Its due for calibration...I'll let the service guy take care of it. In the mean time I'll run it slow.
Thanks

ive talked with a couple of hexagon techs when they were out fixing our machines. in general the machines slated for the European market -z is clockwise, think driving a right handed screw in. the machines for the US are opposite. dont ask me why this is so. i cant remember if they said the setting was hardwired into the controller or if it can be changed but it is not something we the end users have access to. we had fun because all but one of our machines were setup for the US except the last one that was installed. jumping back and forth caused a lot of oops's.

tc1656 It won't take long to get used to it believe me!!
I run both hexagon and nikon machines in the lab, the knob moves Z in opposite direction. I have no problem.

Volume up / volume down for machines made in the US, CW =down / CCW = up for the machines made overseas. A service tech can reverse the joystick sign, something I do to every machine I've had to run that has the "volume" configured knob.

FDC controllers can rotate the orientation around the Z somehow, I've seen it but don't know how. Like how the UJB has the ability to position the stick to move the axis according to the users location on the machine. It's a combination of buttons on the joystick being pressed, but I never like to use a machine like that. I crash more often than not when I use the position feature on a UJB.

FDC panels used to have more access to us non Hex people but they've recently changed a few years ago. I believe changing the axis was one of them along with manual retract.

[Peter Fuller]

Joystick sign is a protected setting, man retract can be set to 0 in PC-DMIS but completely disabling it requires access to the protected section of FDC. But there is some weird button combination you can press on some FDC machines that allows you to change which axis the joystick controls for the X/Y axis. It's done with the joystick itself and not part of the controller settings.

If you can access the FDC Web Interface, you would go to Edit / Parameters / Z Axis / Edit / JogSgn. 0 for US machines or 1 for overseas direction. Then Apply / Save / Exit.
