The surface of the workpiece is spongy

A spongy print surface can be the result of several problems in your 3D printer or printing process. Here are a number of things you can do to resolve this issue:

VERIFY THE G.CODE FILE:

  • Make sure that the Gcode file you generated by the slicing software is correct and error-free. Check that there are no modeling defects in the STL file, such as open edges or non-manifold surfaces, that could cause problems when printing.

VERIFY THE SLICING PARAMETERS:

  • Check that the parameters in the slicing software are correct. Make sure the nozzle diameter, filament diameter, material flow, extrusion temperature, and E-step per mm are set correctly according to the specifications of your printer and the material used.

CHECK THE EXTRUDER:

  • Check that the extruder’s power RJ45 connector is properly connected to the extruder.
  • Check that the hoses connecting the thread puller and extruder are well connected and have no clogging or dirt inside them.
  • Make sure the filament has been loaded correctly and has made it all the way to the melting zone inside the nozzle.
  • Check that the extruder’s cooling fan is working properly.

CHECK THE LEVELING OF THE PRINT BED:

  • If the nozzle is too close to the print bed, the molten filament may have difficulty coming out, causing a blockage in the thread puller and motor gear. Perform a manual leveling of the build bed and clean the toothed gear to remove any dust or debris that may be causing tension during printing.

CHECK THE OPERATION OF THE THREAD PULLER:

  • Make sure the wire puller’s power cord is securely connected to the printer’s motherboard. If necessary, connect the cable while the printer is turned off.
  • Check that the thread taker control is active in the printer menu: Menu > Prepare > Movement > 1mm > Extruder.
  • Check that the black knob of the thread puller is well connected to the motor shaft and that it is not idling. You can do this by pressing and holding the thread puller pliers, leaving the system unlocked, and turning the black knob. Then screw the M3 grub screw onto the flat surface of the motor shaft, making sure the toothed part is aligned with the filament passage.
  • Check that the thread puller motor fan is running. If that doesn’t work, it’s a good idea to contact technical support.
