I'm going to revive this site, I have had multiple of these blobs and changed the print cores, I didn't know what cause the failure, I have:
- changed printcores,
- re-design and installed belt clips with tensioners, (thinking axles fell due to gravity)
- Re-calibrated XY axis, manual buildplate, Level switch, etc.
- Lubricated every axis according to manufacturers website.
I have done the above so many times, I go through the menus with my eyes closed. I've used different methods to secure the prints (salt method, Glue stick) but in a recent print, I've noticed a bang noise during one of the prints, When I checked, the printcore should have changed from the PVA to the PLA and it didn't, the noise was from the printer hitting the dry PLA.
I am at whit's end with this printer, so I am requesting some wise suggestions from this community
