Thread: Noise/vibration on Legend 24TT

    Noise/vibration on Legend 24TT

    Looking for some more advice here. My Epilog 24TT occasionally makes a loud noise (possibly due to vibration) when it is in vector mode. The noise occurs when the head is being moved to the manual focus location or when it is in vector mode. Once the head reaches the spot where it is operating in raster mode, everything seems normal.

    I've called Epilog and they recommend checking the carriage the head runs on (sorry, I don't know the correct name) to see if it is parallel to the back of the machine. If that's not it, they have some additional ideas to check but those all require that I call while I am at the laser to try things.

    If anyone has any ideas on how to troubleshoot this, I'm looking for any inputs I can get.

    What kind of loud noise? clanking/screeching/banging/grinding/whirr??

    I would call it something like a grinding noise. Definitely not like a normal CNC tool's operating sound. The noise is constant while the carriage is moving but as I said earlier, only in vector mode when things are moving fast. When a raster operation is in progress, the grinding noise occurs when the carriage is moving to it's starting point but then the system performs normally with normal sounds after that.

    Mine does make a different sound when going home, and vectoring, never thought much about it.. But it doesn't sound like a metal on metal grind of anykind.. Have you ever greased the bearings? You put a little silicone or white grease on the top and bottom of the rail. Work the carriage back and forth to get the grease into the bearings, then wipe off any that may be left on the rails before running.

    If the slide and guide rails has a small play, lead to the grinding sound every time... As the area top left is commonly used mostly, the probability of the play is more. Possible swap of the rail may reduce.
    Linear guide specs say to operate in one side only as the arrow marked over the rails , so they doesnt recommend the swaping. I tried to swap my rails and got success
