<p>[2018-03-28] User<em>i_has_it</em> found out that the only thing to make it work with<strong>S3D</strong> is to adapt the layer change script like that:</p> <p>;LAYER:[current_layer]</p> <p>[2018-01-25] Thanks to user<em>groenewaldd's</em> hints in the comments i have adapted the script to work for<strong>slic3r*</strong>and<strong>*Cura</strong>.</p> <p>This is practically a remix of <a href="https://www.thingiverse.com/thing:2614204">https://www.thingiverse.com/thing:2614204</a>.<br/> The difference is that it has an overhang on the right side with a pointy cone on top of it. This is supposed to show how exact your printer prints (and cools) small pointy details.<br/> You also can change the direction of where the highest and the lowest temperature will print: on top or on the bottom of the tower.</p> <h3>Usage example in Slic3r:</h3> <h4>1. Generate the tower with openscad:</h4> <p>$ openscad tempTower.scad Set the following variables in the openscad window to your liking:</p> <p>// temperature of the first lowest block start_temp = 220; // temperature of the last highest block end_temp = 185; // change in temperature between successively printed blocks temp_step = 5; Render and export the model to .stl and close openscad.</p> <h4>2. Generate gcode with Slic3r:</h4> <ol> <li>Open the .stl file in Slic3r.</li> <li>Set layer height to 0.2mm. If not, multiply the skip and block parameters by (0.2mm/new_layer_height).</li> <li>Add the following to:<br/> "Printer Settings" -> "Custom G-code" -> "Before layer change G-code": ;LAYER:[layer_num] This makes it possible for the 'setLayerTemperatur.py' script to recognize the single layers.</li> </ol> <ol> <li>Set the initial temperature in the filament settings. The pedestal on which the temperature tower stands will be printed with this temperature.</li> <li><p>Save the .gcode file of the model.<br/> <strong>Attention:</strong> maybe you will have to disable the 'Enable variable layer height feature:' checkbox in the printer settings in order to avoid messing up the temperature distribution over the tower height!</p> <p>#### 3. Write temperature settings to gcode file with setLayerTemperatur.py:</p> </li> <li><p>On the commandline:</p> <p>$ ./setLayerTemperatur.py -h usage: setLayerTemperatur.py [-h] -s STARTTEMP -e ENDTEMP -t TEMPSTEP -f GCODEFILE Sets the proper temperatures to the corresponding layers of a gcode file exported from Slic3r. This allows the temperature tower to have different temperatures per block. optional arguments: -h, --help show this help message and exit required arguments: -s STARTTEMP, --startTemp STARTTEMP Temperature of the first (lowest) block. -e ENDTEMP, --endTemp ENDTEMP Temperature of the last (highest) block. -t TEMPSTEP, --tempStep TEMPSTEP Temperature change between successively printed blocks. -f GCODEFILE, --gcodeFile GCODEFILE The .gcode file to process. $ ./setLayerTemperatur.py -s 240 -e 215 -t 5 -f tempTower_PETG_Black.gcode startTemp: 240 endTemp: 215 tempStep: 5 gcodeFile: "tempTower_PETG_Black.gcode" outFile: "OUT_tempTower_PETG_Black.gcode" step: -5 -> M104 S240 -> M104 S235 -> M104 S230 -> M104 S225 -> M104 S220 -> M104 S215 By now the different temperatures should have been written to a new .gcode file that starts with "OUT_" and ends with the name of your old .gcode file. This file you can send to your printer and the tower should be printed out with the different temperature settings.</p> </li> </ol> <h3>Print instructions</h3><h3>Category: 3D Printing Tests Summary</h3> <p>[2018-03-28] User<em>i_has_it</em> found out that the only thing to make it work with<strong>S3D</strong> is to adapt the layer change script like that:</p> <p>;LAYER:[current_layer]</p> <p>[2018-01-25] Thanks to user<em>groenewaldd's</em> hints in the comments i have adapted the script to work for<strong>slic3r*</strong>and<strong>*Cura</strong>.</p> <p>This is practically a remix of <a href="https://www.thingiverse.com/thing:2614204">https://www.thingiverse.com/thing:2614204</a>.<br/> The difference is that it has an overhang on the right side with a pointy cone on top of it.
