Printer keeps going into recovery

[kbelky 0]

I just purchased a Longer LK5 Pro.  Brand new to 3d printing, although I have printed 8 objects at the local library.  No problems at all at the library.  But with this Longer, it keeps giving an error.  'Recovery Printing - Job is not done.  Do you want to recover this printing?'.   It threw this error 5 times during a print that finally bombed at 14 hours.  Reason being, the extruder seems to 'recover' too low, and hits the object, eventually breaking it free from the bed.

 

I have checked all the fasteners and rollers.  Everything seems dead-on.  Wire connectors have all been unplugged/replugged.  Bed is leveled before each print.  Bed temp is set to 70; Nozzle temp to 210.

 

Any ideas why this error might be coming up?  Anything I can do in Cura to help prevent it?  I'm about ready to send this printer back.  😞

Sounds like an issue with the printer.

I think you are right.  I started a print last night at 9:00.  It finally printed through the night with no error.  But this is what I woke up to.  There is supposed to be one object in the middle.  It was mangled.  Looks like the printer started again at the middle front of the bed.  When that failed, it moved over to the front left.  Oh, and the fan/duct is now bent.

 

Believe I'll be sending this printer back.  😕
