Pulse E-Series Hotend Mount (Non-SNAP)
Over time, the Pulse hotend mount may become loose and require re-tightening. Before proceeding, please be sure that the gantry hardware is not loose and causing any excess movement.
To service the hotend mount, command the Z-axis to lower 100mm from its Home position so that you have adequate room to reach the necessary hardware.
Turn the printer around and locate the lower bearing cover on the rear of the print head. Using a 2.5mm hex wrench, remove the two screws holding the cover in place.
Once the cover is removed, tighten the three screws as shown in the photo below using a 2.5mm hex wrench, but take care not to over-tighten them.
Once tightened, check that the hotend mount is secure, then reattach the bearing cover. Be sure to recalibrate the Z Offset and Bed Leveling before your next print!
