The IT8 calibration with the custom targets is by far my favorite tool. Color correction is a very time. In digital imaging systems, color management is the controlled conversion between the color representations of various devices, such as image scanners, digital.

As promised in http: //www. Marlin code and showing how to set up Pronterface , here is a Thing for calibration of your dual extruder. The details of using Slic. Open. SCAD to create objects for dual extrusion are also presented here. I have merely filled in a few blanks and added a few (hopefully) helpful details and clarifications. All the pieces should be in place for others to build one and implement the firmware and procedures to use it successfully. Hopefully, others will extend this work to other printer designs and other controller boards. The following instructions apply to printing an object which is made with two different materials, two different colors of filament for example. The Open. SCAD process and the amf file creation, as explained below, are not necessary if all you need is a different support material. The sections must have the same origin and orientation. One suggested approach is to create the object with Open. SCAD using two different colors to distinguish the two sections, then export each section separately as an stl. Look at the Open. SCAD file for an example. Since Open. SCAD doesn't export this format, Slic. It is clearest to think of this as a stand- alone utility within Slic. Slic. 3r functions. Select the two files you want to combine. You can select them both at once or one at a time. When you have no more files to select, choose cancel to complete the step. Then choose a file name for the amf file. Note that the first file selected will be printed with the first extruder. Also note that you do not need to do this to use support material. The resulting . amf. It must be brought into the Slic. Plater and sliced as described in a few paragraphs. Under the Multiple Extruders page of the Print Settings tab, Slic. With two extruders, either may be assigned to print perimeters, infill, or support. Notice that the extruders are referred to by numbers 1 and 2, not 0 and 1. Don't worry, Slic. You should then have an Extruder Two page on which you can set up your second extruder. Set the Extruder Offset value to 0 in X and Y directions. These values will be adjusted as you calibrate. On the Custom G- code page, you may want to specify g- code that will turn off your extruders when the print is done. Put M1. 04 T0 S0 in the End G- code section to set the target temperature of Extruder 1 to 0. Duplicate the line with T1 instead of T0 to do the same for Extruder 2. On this tab, we must use the Filament page to specify diameter and temperature settings for the filaments for the two extruders. But notice you have space to set up for only one extruder's filament! The answer is to create an individual configuration file with the applicable settings for each filament. Enter the values for one filament and notice that the modified flag appears on the name bar. Enter all the necessary values, then click the disk icon. Enter an identifying name for this configuration in the Save Preset file box, then click save. The names you enter will be available in the drop down menus. When you have created entries for all the filaments you want to use (at least two), then use the Export Config entry on the File menu to save all the entries. In Slic. 3r, on the Plater tab, locate the second Filament drop down block and find the entry for the filament used in your second extruder. You should end up with two configuration entries for your two filaments. We'll start simple with just a single instance, so click Export g- code.. You always have to use this method to re- slice, but you don't need to create a new . IMPORTANT: It won't work to simply load an stl or . Pronterface. You must use Slic. It uses two colors to show how the extrusion will be done with two extruders. This is extremely helpful when trying to check results from slicing experiments. It works for dual extrusions where a second extruder is used only for support material as well. The offset you specify for the extruders will separate the two sections. Keep that in mind as you view your part. If it looks OK, you can load it into Pronterface, and prepare to print in the usual manner. Be sure to load your g- code file, nothing else. That seems like a hugely complicated process just to do a dual extrusion. But it's really not that bad after a little practice. For comparison, look back at Scribble. J's original dual extrusion piece ( http: //www. To calibrate your dual extruder, slice the object (as described above) with zero offset in the X and Y direction specified in Slic. Measure the X and Y distance from any two points that should be conjunct and put the values in for the X and Y offsets, and go through the slicing process again. If either offset of the second nozzle from the first is nearer the origin, then the offset will be negative. I have a hard time getting this right the first time, but a quick test will tell you what the correct signs are. I measured the offsets from my first test (not shown since the two sections were far apart) and got the result in the first picture on the next try. Notice the small gap along one edge. I adjusted by 1mm and got the second result. I then adjusted again, but got the sign wrong yielding the third picture. The fourth picture shows the final result with a satisfactory calibration. My adjustments were as small as 0.
