Machine beeps, then freezes

[dapoopta]

I am running a TMP1, and just recently it started something odd. I was in the manual mode, trying to face a surface, and all the sudden the machine will beep (the sound it makes when pressing a key), then the buttons will total freeze, meaning I cannot press any of them. The only way to get out of this was to reboot the system. Then after running again, it does the same thing. This just started to do it more than once today, but it has done it randomly in the past. Any ideas?

which software version does it have and what screen does it have the standard or the new 15 inch one

Like Daleman, i would like to know the software version of your machine. I have seen this, once before. It was extremly intermittent and hard to find out the root cause.

[HaasTech83]

Haas has cited poor grounding to the hand-jog wheel to be the cause of the control locking up. If you put a ground wire from the handjog wheel to the pendant, you should be set.

It has a 15" screen (about 14.5 or so cross). The problem hasn't occured in the last day. I also noticed it was happening when I was getting to the outer bounds of my x-y limits. Not sure if it's an encoder issue, but I get not alarms. just total freeze.

do you know which sofware the machine has installed

M15.03D

We had the same problem but only when we went to insert a USB key in the port. I suspect a grounding issue as this occurs when the metal from the key touches the metal housing of the port. I informed HAAS about the problem but like was said before this is very intermittent. Our machine is a July 2007 with the large screen. Knock on wood, we have not had this occur in quite a while.
