Fatal 624 now a " Homing Error"

[das]

Hey there,

My trusty Gerber FX took a dump today -- I was not in my shop when it happened but it went something like this.

machine was booted up ( turned on ), beeped a couple of times, and as the head was to cycle up and down ( homing ) it started to make a loud grinding or buzzing noise. 5-10 seconds it stopped . The display had "fatal error 624 " . This lead me to various troubleshooting sites and to here now.
The machine was restarted so I could hear it make the noise/ see the display - it makes the noise- the Z axis motor is buzzing like crazy and the threaded rod vibrates too. Now the display says " HOMING ERROR " .

Because I haven't had to troubleshoot this machine in the 3 years we have had it ( have preformed regular cleanings, lubes - including the Z Lead screw ) I am wondering where to begin.

This printer has to be off line ( no internet ) while in use ... I dont know if I can check the diagnostics .... Help please and Many thanks.

Thanks - this link is where I had my question origionally posted . No discusion of the HOMING ERROR though.
I had a few more minutes to think about it .... if the head won't move , I woulld get a homing error .

I may have to call service on this one.

Have you lubed the screw for the head movement? If I remember correctly that has been an issue that needs to be done. I do not have a FX just remembering what I have heard on different forums!

This has been done on a regular basis -- even tried it today ( kinda pointless if it won't budge : ) Gerber says to do the same thing --fast fact # 4290.

Update :

Pulled the cover off of the FX ( 2 Allen screws on the back, 2 Allen screws on the inside )

Noticed the screw coming out of the motor was binding a bit against a cross member in the machine - that cant be good.

Turned on the machine and waited for it to cycle and home -- it worked.

Ran a short job through the machine .

With the print head all the way down-- added a dab of lube behind the " nut " that travels the screw coming out of the motor.
Gerber has made is inconvenient to lube this part of the screw- on my machine , it had very little lube at the home position.

This seems to have fixed it for now . It is also quiet like it was when new. This “ fix “ will also become a more regular part of the maintenance.

Thanks for the input and suggestions.
