cant figure out this VF1 behaviour...

Hi


Haas VF1


We had this power outage while the machine was in the middle of taking a groove with circular interpolation.

When we had the power back on , we did the usual .. ie turn on the 'JOG without zero return'
and then turn off the ' door open interlock' so that we can take out the tool from the component without damage.

All fine till now. we moved first the X a bit then the y a bit .. then the machine refused to move any more .
we then turned the power off and on again , then continued the tool removal operation ,when it timed out on us again.

we had to do this 4 times before we could get the tool out . each handle operation timed out in about 10 seconds....

the other VF1 and VF4 dont behave like this . we can keep moving in handle ( albeit very slowly) before the reference for as long as we want.

Any ideas ??

Thanks

I "zero single axis" to get the z axis then do a normal power up, works on all 9 of ours.

Thanks
But in this case we couldn't do that cos the tool was inside the groove , so we has to move x and y before we could move z....

Did you try changing the jog increment to .001, maybe it switched over or was changed. Mine will only jog .001 in that mode, everything else is a no-go.

Machine alarms out or just doesn't move anymore.

Thanks Sim.

It was in the minimum .001 ( We wouldnt have dared try in any other because we had very little clearance to work with....)
