Hi Jay

Just watched the video on Youtube

Have a look yourself, but it looks like the air you can hear on tool change is normal.

I would suspect your air system is not up to the job, when the air escapes at the tool change, the pressure will drop and it may be dropping to low for the machine to continue the cycle.

Its only me guessing and I might be way off the mark but if it was working before moving it I would say it will be something simple.

Do you have a manual for it?

Is there any info on the machine regarding air pressure supply and CFM?
