Densifier Alignment and Troubleshooting

If the printer is not homing XY correctly, this will cause issues at the densifier.

Follow our full XY Homing Error guide to test XY homing and resolve any failure

If XY is homing correctly, proceed to step 2

Check that the top two screws on the densifier are fully tightened

Clean the inside of the densifier of any material. Ensure that the densifier swing can move all the way up

Check if the swing cover is bent or damaged, as in the photo. If so, contact Mosaic for a replacement.

From the side, check if the densifier lip is bent or damaged. If so, contact Mosaic for a replacement

Check that the two clam shells are fully snapped together. If there is a visible gap, as in the photo, try squeezing the two shells back together

You can jiggle the metal lip sightly to get it into position as you squeeze the clam shells together

When the densifier swing is moved up, the densifier ram should retract, leaving the hole completely open

Move the swing up manually and check if the ram retracts fully. If not, apply lubricant (WD-40) to the densifier in the three locations indicated

If the ram still does not retract when the swing is in the upwards position, contact your Account Manager or support@mosaicmfg.com

Clean the hot end by heating nozzle and using a wire brush, or similar, to clean any excess material

Load material into the Print Head and check that the hot end can extrude, using Printer > Controls

Turn off Element and remove the Print Head. Check if the nozzle looks skewed, as in the photo. Share with your Account Manager or support@mosaicmfg.com for confirmation

A possible cause of misalignment is due to a skewed or loose fixed end. To check for this, turn off Element and remove the Print Head

Tighten these two screws on the bottom of the fixed end, while pushing straight down firmly on the top of the fixed end

If the densifier and print head are in working order, it's now time to test densifier alignment. Proceed to Settings > Troubleshooting to begin the testing workflow

Make sure the nozzle is clean, then begin the densifier alignment check. The Print Head will home in XY and Z, then move to the alignment position at the densifier

Following the on-screen instructions, check that the nozzle is aligned with the left edge of the rectangular heat block, on top of the densifier swing. Adjust and retest the alignment as necessary, before saving. Monitor densifier performance at the start of the next print.

The maximum adjustment is 2mm in either direction. If this is insufficient to for correct alignment, you are likely seeing an XY Homing Error. Contact support@mosaicmfg.com for more help
