New intelligent bridging algorithms in Version 4. The results provide substantial improvements over past versions, giving your prints a higher chance of success while improving the underside surfaces. This allows you to create more efficient and tightly packed print jobs while maintaining full control over rafts, skirts, prime pillars, and ooze shields.
Simplify3D is known for its ability to process incredibly large or complex models with ease. Import larger models, export files faster, and take your printing to the next level. Solid layers in Version 4. The software also has the ability to alter the solid layer toolpaths to create a stronger bond with the perimeters above and below, increasing the Z-axis strength of the finished part. We have been working closely with hardware manufacturers around the world to ensure that Version 4. Click here to confirm if your printer is now supported.
The distance that the toolhead moves after sending this command is equal to the X and Y origin offsets. For example, if the head moves 10mm to the right after sending this command, then the origin offset should be 10,0,0. Once the build volume and origin offsets are properly configured, the location of your prints should match the location of the parts in Simplify3D. This typically means that one of the axes on your printer is moving in the opposite direction of what Simplify3D expects.
If the preview you are seeing in Simplify3D looks drastically different than the original part, you should first verify that there are no issues with the mesh. You can do this using the Repair menu in Simplify3D. If the software identifies non-manifold or self-intersecting surfaces, you will need to repair your model before slicing. Many users have had great success using free online repair sites such as Netfabb or MakePrintable, so this may be a useful thing to try first.
For more information about identifying and repairing these issues, please see the Identifying and Repairing Common Mesh Errors tutorial. If this setting is enabled, it will turn your entire model into a solid object, removing all holes and internal features from the part. This can be a very useful for working with models that contain errors or are not completely water-tight, but if it is enabled by accident, it will also fill in all the holes in your model.
Make sure this option is disabled and then try to slice the file a second time. This typically means that the toolhead offsets in the firmware are not properly configured. Each extruder has different toolhead offsets, which define the position of that extruder relative to the others. If one of these offsets is not correct, it means that whenever you print with this extruder, the toolhead will not be properly positioned. Please consult with your printer manufacturer for instructions on changing and saving the toolhead offsets in the firmware.
The first thing to do is to contact our support team to make them aware of your issue. Our 3D printing experts can frequently help with any common printing or setup issues you might encounter. In the event that they are not able to help with your issue, we offer a day refund policy and the same support team can guide you through that process.
Please refer to the following section in the Simplify3D print quality guide: Dimensional Accuracy. Your printer already includes an internal setting known as the toolhead offsets, which defines the position of each extruder relative to one another.
However, if this setting was not configured correctly by the manufacturer, you will need to correct this error first before your extruders can be properly aligned.
So how do you determine the correct value for your toolhead offsets? The toolhead offset tells the printer how far each extruder will need to move along the X and Y axes before it ends up in the same spot as the primary extruder Tool 0. You can look on the Extruder tab of your Simplify3D process settings to verify the toolhead number for each extruder. So if your primary extruder is on the right, and your second extruder is 34mm to the left of this extruder, then you know the second extruder would need to move 34mm to the right before it ends up in the same position as the primary extruder.
Now that you know the correct toolhead offsets, we will explain how to update the printer with the new values. There are 3 different ways this can be accomplished depending on what printer you have:. So if your printer has an LCD menu, check for this option first. If your machine uses the Marlin firmware, then you also have the option of sending gcode commands directly to the printer to update this setting.
The machine should respond by listing the current toolhead offsets. To update this value, send the following command:. That tells the printer to change the X-axis offset to 34mm for the second extruder Tool 1. The machine should reply confirming the change. This ensures that this setting will be maintained even after the printer is turned off. If your machine does not support EEPROM storage, you can also place the correct M command at the very top of your Simplify3D starting script so that it gets sent to the machine before each print.
If you were not able to update the toolhead offsets using either of the options above, you also have the option of editing the Configuration. Please contact the printer manufacturer for instructions on this process. If you were not able to update the toolhead offsets using the instructions above, then the software includes one other option you can use to account for the misconfigured firmware.
After enabling this option, the software will actually shift all of the coordinates in your gcode files anytime you are printing with the second extruder. You should notice that all of the extrusions for Tool 1 have now been shifted by the amount you entered. This verifies that the setting is working correctly. This will download a fresh copy of this profile and configure the software for this machine. By default, the preview used in Simplify3D is very detailed, so if you are running on a machine with limited resources, you may want to alter these settings.
This will render a much simpler preview that will use fewer system resources. The easiest way to open Simplify3D on your Linux machine is to open a Terminal and cd to the installation directory. Then type the following command:. This ensures that Simplify3D will be able to correctly access the serial port for your printer and will have the necessary permissions for saving your application preferences.
This usually means that there is a permissions issue where the software does not have sufficient access to save and restore your settings. On Windows, you may want to try right-clicking and choosing Run As Administrator to see if this resolves the issue.
If you are using a Linux machine, please see the recommended instructions in this question. The process for removing the settings and files used by the software is different depending on which operating system you are using. This is a hidden directory, so you may need to enable viewing hidden files and folders to see it in an explorer window. However, if you are unable to open the software at all, then this typically means that there is a problem with the system requirements or the settings that are saved and reloaded when the application starts.
To verify the cause for this problem, it can be useful to look at the crash log generated by the software. This should be the latest crash report for the software. Please copy this report in case you need to reference it later. If you are still unable to open the software after following the instructions above, then the next thing to try is clearing the settings and saved files that are loaded when the application starts.
Please see this question for more details. First of all, please keep in mind that you can only have one program connected to your 3D printer at any given time. Close any other programs that could be communicating with the printer. If you are using the software on Windows, you will also need to make sure that you have installed the USB drivers required by your printer. If you are able to connect to the printer from a different software program, then you likely already have the necessary drivers installed.
If you do not know which drivers to use, please consult with the printer manufacturer. After completing the steps above, go ahead and turn on the printer and then plug it into your computer. If you click on the Communication tab, you can see all of the commands that are sent back and forth to the printer. In most cases, the software will automatically establish a connection with your printer. If the software does not automatically connect, make sure that you have selected the correct port and baud rate in the top-left of the Machine Control Panel.
If either of these options are incorrect, the software will not be able to communicate with the printer. Chances are, your printer is supported!

With Version 4. Jump to Location — New controls allow you to jump to an exact line or layer number to quickly examine a specific point in time.
This makes it much easier to navigate to different sections of your print. Position Readout — The XYZ position of the tool head is now displayed in the print preview, allowing you to verify the exact Z-height or XY location where an event occurs. Range Controls — New options allow you to limit the number of layers or lines that are shown in the preview. For example, if you know an issue occurred somewhere towards the end of your print, you can easily restrict the preview to only showing the last 20 layers.
Keep scrolling to learn more about Simplify3D 4. Several new features have been added to improve the adhesion between the bottom of your supports and the build platform. This can be particularly helpful for tall prints, where the supports need to be securely anchored to the bed to ensure they stay attached for the entire print.
Simplify3D includes a feature called Dense Supports, which will vary the density of your support structures near the surface of your part. This can provide a better foundation for your model, improving the print quality while still saving valuable amounts of material. Version 4. This allows you to optimize many aspects of your supports, and the savings quickly add up! Simplify3D is well known for providing support structures that easily separate from your model, and we wanted to bring this same level of performance to the the raft.
We have also added new speed settings that can further customize the adhesion between the raft and your part. Along with a new design for the rafts, we have also optimized the actual placement and sizing of the rafts to ensure they are only used in the areas where they are absolutely needed. New options to define the exact speed, flowrate, and temperatures that are used for the outlines of your bridging regions.
Using these precise properties for your bridging perimeters can greatly improve your odds of success! You can also specify a custom direction for these layers if you want to try your own approach.
