| Why can't I move the print head or build plate? faq Answer: The motors are on. Explanation: In addition to moving the head, bed and gantry, the motor also lock the head, bed or gantry to the controlled positioned. | |
| Why can't I get a good first layer? Why won't my prints stick to the bed? faq Answer: Usually a combination of the following factors: Dirty Plate Clean the Bed Plate Bad Z Offset Read about How to set the z offset Bed Not Level Level the bed with the SCREWS_TILT_CALCULATE First layer speeds too fast Try slowing down to 30mm/s. | |
| What are good retraction settings? faq Answer: 0.8mm retraction at 55mm/s with 0.6mm of spiral z-hop. Spiral z-hop requires Orca Slicer and that gcode arcs are enabled both on the printer in printer.cfg and in Orca. Enable retratcion on layer change and moves over certain lengths. | |
| How should I clean the bed? faq Answer: Wash with dish soap and hot water. Air Dry. NO alcohol. Discussion See Cleaning the Bed Plate for complete discussion. | |
| How should I set the Z Offset to adjust nozzle height? z_offset faq Answer: The best method is by observation for the proper filament squish while baby steps adjusting the z offset value during a test first layer print. Discussion: Filament Squish? Huh? (work in progress.. in the mean time see | |
| What are Klipper Macros? faq about articles ...coming soon... | |
| Nozzle Replacement faq about How to replace the nozzle Elegoo has a Nozzle Replacement Video that demonstrates the proper process that carefully avoids potential causes of damage. When to replace the nozzle (...work in progress...) | |
| What causes parts to be knocked off or shift on the bed plate? faq articles Normally this is caused by a combination of the following issues: Poor Choice of Infill Pattern Infill patterns that cross already drawn infill lines (e.g. grid) are inconsistent with high print velocities. Use patterns like Cross Hatch, Gyroid or Honeycomb instead. Patterns like Cross Hatch offer a good balance of strength and speed along with requiring less infill density (%) than other patterns to achieve the sa… | |
| How can you revert the printer firmware back to the original state? faq Anser: You can use the OpenNeptune project's restore images for the software and the whole eMMC. See <https://github.com/OpenNeptune3D/OpenNept4une/wiki/Reverting-back-to-Original-Elegoo-Firmware-&-Software> | |
| How to run a Bed Mesh faq Defining the Bed Mesh We have to have the bed mesh parameter's define before running a bed mes. They are stored in printer.cfg Example for Neptune 4 and Neptune 4 Pro: [bed_mesh] mesh_min:10,21 mesh_max:210,211 probe_count: 9,9 algorithm:bicubic bicubic_tension:0.2 mesh_pps: 4, 4 split_delta_z: 0.020 fade_start: 4 fade_end: 12 | |
| Should you update the firmware? faq Answer: No. Discussion: It's not necessary. It will not resolve any printing issues you're having with your prints. There are no beneficial software changes or fixes for the printer itself. The more recent updates actually purposefully break a key | |
| What is a Slicer? faq The Neptune 4 is a FDM [fused deposition modeling] or FFF [fused filament fabrication] printer, meaning it builds up the print layer by layer. In order to print an object we use software to “slice” it into layers of drawn patterns made from the extruder that combine (fuse) together to form the finished part. | |
| Where can I find further resources? faq Answer: See Resources | |
| Why does the Z Offset Drift, Vary or is Lost? faq z_offset Answer: Should it be saved? The value for the gcode z offset that fine adjusts layer height to properly shape the filament cross section is not saved in printer.cfg. The Elegoo ancillary screen has workflows that attempt to save it to a file yet this is not a standard Klipper practice and using other printer controls results in indeterministic results. | |
| Why are feeler gauges a bad idea and in general just wooly thinking? faq When setting the z offset what's bad about using feeler gauges? Answer: Feeler gauges are a horrible idea for several reasons: * metal feeler gauges thermally change dimension | |
| Why should I set the Z Offset to adjust nozzle height? faq z_offset Answer: It shapes (squishes) the extrusion so that it bonds better to the surface beneath and adjacent perimeters and infill. This improves adhesion and the strength of the print. It also is critical for getting a good first layer. | |
| Why shouldn't the z offset be saved? faq Wouldn't it make sense to have the printer save the z offset? It gets “lost” between RESTARTs and power cycling. Answer: For various different reasons the value isn't a consistent single value worth saving: |
