|
| System is pressurized but the printer doesn't extrude paste or extrusion is discontinuous |
Feed pressure is insufficient |
- Remove nozzle and stator from metering valve using the appropriate adjustment screw, increase feed pressure slowly in increments of 5-10psi until paste begins to flow from bottom of valve body.
- Release feed pressure.
- Clean paste from bottom of valve body with a wet paper towel Reinstall stator and nozzle.
|
| Nozzle is plugged |
- Clean Nozzle.
- Clean Metering Valve.
|
| Paste extrusion stepper motor unplugged or defective |
- Check if stepper is running.
- Check connection.
- Replace stepper.
|
| Nozzle plugs frequently |
Metering valve stepper overheating, causing paste to dry in valve |
- Feel stepper heat sink and metering valve body. If valve body feels hot, or heat sink is too hot to touch, the stepper is overheating.
- Reduce current setting at metering valve stepper driver.
|
| Stator is damaged |
Remove stator from metering valve, clean, visually inspect to determine if stator is shedding material If stator is damaged, replace [PN: 100789]. |
| Paste leaks from nozzle when metering valve stepper is stopped |
Stator or rotor is worn out |
Replace Stator [PN: 100789]. If problem still occurs, replace Rotor Assembly [PN: 01-08-0120]. |
| Print bed Z-offset won't set correctly |
Print bed is short circuiting |
- Check if the green light on the PCB behind nozzle is on. If it is on, the print bed is short circuiting, and it will not reset Z-axis height correctly.
- Remove the stainless print sheet on the print bed, and check if any metallic piece is penetrating the magnet on the print bed, or if it is on the sides of the print bed.
- Clean the print bed and put back the stainless print sheet to ensure no more short circuit is occurring.
- Ensure the removable build sheet is not overhanging the bed and making contact with other metal parts of the printer (for example, the nozzle cleaning brush holder).

| Charge pump motor vibrating loudly |
Difficult/ insufficient water flow into rotary vane water pump |
Water filter may have reached end of life. Indicator may be the presence of bubbles in the water inflow line (clear tubing). Replace Water Filter [PN: 100667]. |
