Sensor Status Troubleshooting

On Element Desktop, access the Sensor Status screen under Settings > Troubleshooting > Sensor Status when not printing

During printing, access under More > Sensor Status

On Array, access the Sensor Status screen for individual Elements from the front screen, under Element > Troubleshooting > Sensor Status

Alternatively, access from the back screen under Element > Sensor Status

A grey sensor status indicates that filament is not detected by the sensor at that location in the system. Green indicates that filament is detected.

In the Palette X assembly, the sensor is located just below the cutter. To test the sensor, feed filament through Palette X manually, or by using Material Pod controls under Materials > Drive

If filament cannot pass the cutter, perform a cut operation under Controls > More. If the issue persists, refer to Cutter Troubleshooting

If the sensor status is green without feeding filament through Palette X, refer to steps 4 and 5 of our Filament Pathway Inspection and Clearing Guide. There is likely a small piece of filament broken inside Palette X that needs to be cleared

If Palette X is clear of debris, but the sensor status does not correspond properly to whether filament is present at the sensor, please contact support@mosaicmfg.com

To test the Print Head sensor, remove the PTFE tube from the top of the Print Head using the quarter-turn mechanism

The sensor is located below the acrylic cover, labelled 'Filament switch'

Insert a piece of filament into the Print Head and check the sensor status. If the status does not correspond properly, please follow the steps in our Print Head Disconnection article and contact support@mosaicmfg.com

If you cannot insert filament into the Print Head, as there is already a piece inside, refer to Clearing the Print Head

If a Material Pod is feeding constantly throughout a print, this can indicate an issue with the microbuffer sensors

To access the microbuffer on Element Desktop, remove the back panel of the printer. Take care not to strip any screws - go slowly and use consistent force

On Element Array, the microbuffer is openly accessible at the back of each printer

The first picture shows the microbuffer in the 'min' position. To put the microbuffer in the 'min' position, push the ingoing tube all the way to the right, into the microbuffer

The second picture shows the 'max' position. To put the microbuffer in the 'max' position, pull the ingoing tube all the way to the left, away from the microbuffer

If the sensor status is not corresponding properly to the microbuffer position, clean any debris out of the microbuffer by disconnecting the tubes and using compressed air. If the issue persists after cleaning, contact support@mosaicmfg.com

There are two sensors in each Material Pod. The filament will contact the right sensor first, and then the left.

With the Material Pod installed in Element, you can check these sensors are working properly. Report any issues to support@mosaicmfg.com

If you see a failure when Element is switching between Material Pods during a print, please note the sensor statuses of both Material Pods when reporting the issue to Mosaic Support
