| 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 | |
| Extruder clicking and not extruding faq howto The filament can’t extrude for some reason and the extruder drive is trying to push the filament through the hot end yet it’s not going through. This cases the clicking sound and we see the extruder thumb wheel skipping. | |
| Why can't I get a good first layer? Why won't my prints stick to the bed? faq articles Answer: Usually a combination of the following factors: Operator & Setup issues Follow the setup instructions. Dirty Plate Clean the Bed Plate Residue from incompatible materials Clean your build plate when switching between filament types (e.g. from PLA to PETG), or use a dedicated build plate for each material type. Alcohol will not clean the sugars residue on build plates left by PLA. Use a clean… | |
| 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 to fix "Heater not heating at expected rate" articles howto about faq Discussion: Klipper uses an algorithm (PID controller) to monitor your heater's temperatures (using a thermistor on the hot end or in the bed to read the temperature) and adaptively apply current to the heating element(s) to maintain the stable temperature you've set. | |
| 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. The paper method will not produce a correct result. | |
| 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 Generally nozzles are changed when worn. Clogged nozzle can normally be heater to a higher temp and flushed. When the flow ratio needs adjusted further downwards is an indicator the nozzle is wearing. It also could be changed after repeated printing with highly abrasive materials such a… | |
| Nozzle Types What different types of nozzles are there? Why and when would you want to use them? What's the "best" nozzle? about faq Overview Typically nozzles are made of brass, and these are the nozzles that ship with the printer. Brass offers excellent thermal characteristics; it heats quickly and maintains temperature well while transferring heat. This makes it efficient. It's also cheap and easy to produce. It suffers however from being very soft and wears easily, even | |
| 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: Bed not level Run SCREWS_TILT_CALCULATE to level the bed or to check that it’s level. Bad gcode Z Offset A poor gcode z offset results in poor bed and layer adhesion and can cause the part to separate or move on the plate, resulting in the part shifting to getting knocked off the plate. | |
| POM? What's that? faq Delrin, or POM (an abbreviation for PolyOxyMethalate), is the material from which your X and Y axis wheels are made of on your Neptune 4 (excepting the Pro model, which uses linear rails.) POM is a low friction plastic, with high wearability, and is impervious to most oils and solvents making it an excellent choice. | |
| 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 articles setup 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. | |
| What do I need to do after swapping my nozzle, hot end or toolhead? faq setup After swapping the nozzle, hot end or toolhead the printer geometry and ofter factors will be different and require certain recalibrations: Swapped Nozzle This assumes swapping for identical nozzle, not nozzle materials or model/manufacturers, otherwise follow Nozzle + Hot End instructions. | |
| Thumbnails faq article about Select ColPic for format of g-code thumbnails. Some versions of Moonraker in the Elegoo distributed firmware distributions have issues displaying thubnails on the side microcontroller Display and/or in Fluidd. Sometimes this is seen using Orca when Cura may work when using as the slicer. These issues are related to what thumbnail formats are included by the slicer and which are configured in Moonraker. | |
| 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 Discussion How do you know it's changed when your references for position have shifted? Owners that believe their gcode z offset is “lost”, drifts or varies from what it “should be” often find the following also true: | |
| 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 is Orca slower than Cura? faq Issue: Users report that when they switch from slicing with Cura to slicing with Orca their prints take longer to print.. Answer: It's not. This is a user configuration issue. The filament profile Max Volumetric Flow Rate limits overall print speed, as calibration not present in Cura. The default filament profiles for default PLAs and other materials are set to the lowest common denominator to better assure reliable prints yet are normally set significa… | |
| 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: |
