Y Axis Bearing

[Jimh321 0]

We have had a slight fail with our UM3E we came in to find it bathing itself in a giant ball of PLA.

After having spent some time cleaning all the mess off it the culprit looks to be a seized Y axis linear bearing, after some working and oiling we managed to get it moving again but it's really not happy.

Where do we get spares from for this machine? It is only a few months old and has been very reliable up to now, it's in daily use and I don't want to have to send it away for weeks to be repaired.

Many Thanks

Nice picture, thank you for the nightmares

You should contact your printer reseller to ask for a spare bearing. When you say "Y axis linear bearing", do you mean the one inside the print head or one of the brass "bearings" in the sliding blocks?

Either way, I wonder what happened to the printhead. Did it get stuck and extruded filament in one place? If that's the case, the small silicone rubber piece at the nozzle tip should have prevented it. Check that one too and replace it.
