| 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. How to disable to power off motors | |
| 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. | |
| Food Safe Prints? faq article Are there materials that I can print with that are food safe? Can I use my 3D prints for use with food items? Answer: No. While the materials that you use to print with might generally be food safe (e.g. PETG), the resulting prints are not advised for use or contact with food. | |
| 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? faq z_offset 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 | |
| Important Changes faq Klipper 20230201 The [bed_mesh] module no longer loads the default profile on startup. It is recommended that users who use the default profile add BED_MESH_PROFILE LOAD=default to their START_PRINT' macro (or to their slicer's “ | |
| What do the numbers on the Level screen tell me? faq Answer Nothing useful. Discussion This is the Level dashboard of the Screen. What are the numbers? Heater Temps At the very top of the screen here we see the current/set temperature values for the extruder and the bed. These are set normally through your gcode when you print yet they could have been set manually. In this case while the value of 60C for the bed is adequate for printing PLA the value for the extruder is below tempera… | |
| What are Klipper Macros? faq about articles ...work in progress... Macros are small programs or functions written in Klipper gcode. They're defined in printer.cfg (or files that it includes) and are loaded when Klipper performs a soft or hard restart (RESTART or FIRMWARE_RESTART respectively), which reads printer.cfg. | |
| 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 defined before running a bed mesh. 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. | |
| Tips for better first layers articles faq It is critically important to get the first layer of the print right, When the first layer is not the best it can be then it can lead to complete failure, parts detaching, and warping. There are several techniques and recommendations one can heed in order to minimize the chance of this happening. | |
| 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 z_offset 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: |
