Notes |
| Bed Leveling |
|
- After an initial setup, re-levelling the bed is rarely required
|
| Extruder Flowrate |
- After cleaning / replacing Metering valve components on either toolhead
- After changing or reloading material
- If the printer has been sitting idle for several days
|
|
| Bed Offset |
- After cleaning / replacing Metering valve components on either toolhead
- After changing to a new material
|
- This routine is required for new material changes since the toolhead is cleaned in the process
|
| XY Calibration |
- After cleaning / replacing Metering valve components on either toolhead
- After changing to a new material
|
- This routine is required for new material changes since the toolhead is cleaned in the process
|
| Cleaning the Nozzle |
- Clog in the Metering Valve
- Storing printer for more than 4 weeks of non-use
|
|
| Reloading Material |
- When cartridge is empty
- Feedstock issues (drying out inside hose, fluid separating, etc.)
- The feedstock has expired
|
|
| Changing Material |
- When the cartridge is empty
- Feedstock issues (drying out inside hose, fluid separating, etc.)
- The feedstock has expired
|
|
| Cleaning the Paste Feed Hose |
- Changing to a different material
- Feedstock issues (drying out inside hose, fluid separating, etc.)
|
|
| Changing the Nozzle |
- When it's too difficult to clean out the nozzle tip
- When a spare nozzle assembly is available to quickly replace it with
|
- It can be more convenient to replace the assembly if you're in a hurry. The previous tip can be soaked in water and cleaned / replaced at your convenience
|
| Changing the Nozzle Tip |
- The tip is damaged / bent
- When it's too difficult to clean out the nozzle tip
|
- The nozzle tip does not wear as quickly as conventional plastic FDM due to the extruder being at room temperature.
- While no noticeable wear has been seen within 3000 hours of printing (has not been tested past this), we do recommend to change the nozzle tip after this duration.
|
| Cleaning the Metering Valve |
- Changing to a different material
- Rotor is being replaced
- Clogs where the motor stalls with the nozzle fully removed
|
- There can be several causes for persistent clogs (like the material drying out inside the Metering Valve)
|
| Replacing the Stator |
- ~500 hours of printing
- Poor Metering Valve performance
- Stator is visibly damaged
|
- Review xxx for common symptoms of Stator damage & poor Metering Valve performance
- Stator lifetime may exceed lifetime estimates; evaluate the Metering Valve performance periodically and the appearance/condition of the components when cleaning
|
| Replacing the Rotor |
- ~1200 hours of printing
- If replacing the Stator does not improve Metering Valve performance
- Rotor is visibly damaged
|
- Review xxx for common symptoms of Rotor damage & poor Metering Valve performance
- Rotor lifetime may exceed lifetime estimates; evaluate the Metering Valve performance periodically and the appearance/condition of the components when cleaning
|
| Priming the Charge Pump |
|
- After initial installation, priming the pump is required infrequently.
- Typical scenarios: the printer water reservoir sits low for very long periods of time or if the water system components fail and need replacement
|
| Greasing the Lead Screw |
|
- If the Zed axis becomes noisy, some grease applied directly to the lead screw will alleviate this.
