To resume the print, once again use the printer’s control panel or the host software. Make sure to remove any strings of extruded filament from the nozzle with a pair of tweezers first. Once the color of the extruded filament is the same as the filament going into the hotend, you can resume the print. I think this is because leftover dark pigment is more easily visible in light filament than vice versa. Purging the old filament can take a while, especially when switching from a darker to a lighter filament.

How to change filament colors after pausing the printĪfter pausing the print, whichever method you used, the next step is to change to a different filament color. After setting the right layer heights in the script, you will be able to pause 3D prints at the exact height you want. In many cases you will be able to find an example pause at layer height script online for your 3D printer that you can use. In short, you need to insert the right post-processing script in your slicer, and make sure that the G-code in the script is correct for your specific 3D printer. For example, Cura has a built-in post-processing script for pausing at specific heights, whereas Slic3r supports external post-processing scripts in a variety of languages such as Perl, Python, Ruby and Bash. Other slicers have their own implementation of post-processing scripts. You can find more information on the post-processing feature in Simplif圓D on this page. For the example where I want to automatically pause at layer 11 Z2.20, I would add the following: In the corresponding text box you can enter a script that inserts the pause G-code. You can do this by going to Edit Process Settings -> Scripts and then finding the “Additional terminal commands for post-processing” section at the bottom. In Simplif圓D it is possible to automatically insert the pause commands when the G-code is generated. Inserting pause commands with post-processing in Simplif圓D This script inserts the pause commands at the relevant locations. Slicers usually do this by running a post-processing script after generating the G-code. This saves quite a bit of time and effort when you want to pause a print several times.

Make sure to look up the pause command that works for your printer! How to automatically insert pause commands in G-codeĪside from manually editing G-code, it is also possible to have the slicer software automatically insert pause commands when the G-code for the print is generated. For example, on the Duplicator i3 the G-code to pause is M25. The M600 pause command works for many printers, but not for all of them. So what I did there was insert the pause G-code right before the command that moves the 3D printer to Z2.20 ( G1 Z2.200 F300). In the example from before, where I want to pause the print at Z2.20, the resulting section of G-code would look something like this: G92 E0.0000 I let the hotend move upwards first so that any filament that oozes out of the nozzle will be in mid-air instead of oozing on the print. This moves the nozzle up 10mm, and then pauses the print. For example, the G-code I add to pause the print is as follows: G91 set relative positioning Edit the G-code by adding pause commands. Generate the regular G-code for the print and open it in a text editor like Notepad.ģ. This means that if I want to print with a different color starting with that layer, I need to pause and swap out the filament at the beginning of that layer.Ģ. In the bottom left corner I can see that it has a Z position of 2.20. First, find in your slicing software the exact layer(s) you want to swap colors at.įor example, in Simplif圓D I adjust the layer preview slider until I am at the layer that needs a different color.

To manually edit G-code to set up a 3D print for automatic pausing, you can do the following:ġ. How to manually edit G-code to pause a print You can do this by hand, or you can have the slicer software do it for you. Once the printer reaches a specific layer that you want to swap the filament at, it does the pausing without any human input.Įditing the G-code involves inserting pause commands. One advantage of this method is that there is no need to monitor the 3D printer. This causes the printer to automatically interrupt the print and enter a pause state. If you need more precise control, for example, if you want to swap filament on a layer change, it is best to edit the G-code of the print. You will need to keep an eye on your printer to identify the approximate moment you want to swap out the filament. If the exact point you want to swap out the filament is not very important, you can simply manually pause the print using the printer’s host software, or by using the printer’s control panel. You can either pause the 3D printer by hand, or edit the G-code so that the 3D printer pauses automatically at specific points during the print.
