Known Issues

warning

Extended Print Startup Time

Flow calibration and bed leveling add significant time before every print, approximately 20 minutes.

Mitigation: Plan for longer print preparation times; consider batch printing to offset startup durations.

warning

Layer Shifting

Some users have reported layer shifts occurring in approximately 1 out of 8 prints.

Mitigation: Ensure the printer is on a stable surface; check for loose belts or components; monitor prints closely.
