prusaprinters

<p>It's a remix from my original design (<a href="https://www.prusaprinters.org/fr/prints/16909-prusa-mk3s-mmu2s-purge-bucket">https://www.prusaprinters.org/fr/prints/16909-prusa-mk3s-mmu2s-purge-bucket</a>)</p> <p>I redesigned the holder to match with my new X axis (<a href="https://www.thingiverse.com/thing:3670659">https://www.thingiverse.com/thing:3670659</a>)</p> <p>Now, this purge bucket can be installed on all X axis versions (stock, Bear, ...)</p> <p>Z-axis top right should be replace for that. STL is available (directly remixed from Prusa website).</p> <p>To print correctly (PETG 0.2mm 20% grid), please print these parts according to the last picture. <b> Don't print the Holder lying flat.</b></p> <p>Holder : supports everywhere<br/> Spacer: supports from build plate only<br/> Trigger: no supports<br/> Bucket: supports from build plate only</p> <h3>Materials needed: </h3><ul> <li>1 screw M3x20 for trigger, but you can use the trigger without screw with stock extruder (not tested on others)</li> <li>1 screw M3x4</li> <li><p>1 rubber band or a spring 20.6x5.1. I advise you the spring.</p> <p>Please follow this instruction list: (also available in Files with pictures, here : <a href="https://www.thingiverse.com/thing:4704964">https://www.thingiverse.com/thing:4704964</a>)</p> </li> </ul> <h3>HARDWARE PART :</h3><ol> <li>Add screw on the trigger (according to the trigger used)</li> <li>Add rubber band (or spring) between holder and spacer</li> <li>Add screw on the spacer to hold the bucket (need adjustment after the installation)</li> <li>Remove Z-axis top right</li> <li>Remove rod 8mm</li> <li>Install holder with spacer and trigger</li> <li>Put the rod 8mm (be careful with bearing)</li> <li>Replace Z-axis top right by the new part</li> <li>Check rotation if it's free. It's NOK, check that all supports on holder are removed. (I know, it's not easy...)</li> <li>Adjust position of the bucket and the screw on the trigger</li> <li><p>Perform a Calibration Z.</p> <p>It's finished for the Hardware part!</p> </li> </ol> <p><h3>SOFTWARE PART: </h3><br/> In PrusaSlicer,</p> <ol> <li>Go to "Print Settings" and uncheck "Wipe tower"</li> <li>Go to "Printer Settings" and copy/paste this script in the tool change section:</li> </ol> <p>; toolchange from [current_extruder] to [next_extruder], layer [layer_num]<br/> {if current_extruder != next_extruder}<br/> ;<em>before tool change<br/> M106 S0 ;turn off fan<br/> G92 E0 ;turn off retraction<br/> G1 E-0.8 F2100 ;retract<br/> G1 Y100 F12000 ;break filament before lifting<br/> G1 X200 F12000 ;move head to position<br/> ; G91;change in relative position<br/> {if layer_z &lt; 25.0}<br/> G1 Z26; z-lift if lower than 25 mm<br/> {endif}<br/> G90;transition to absolute position<br/> G4 S0 ;clean up buffer movement<br/> G1 X240 F12000 ;move head to purge area<br/> G1 X250 F2000<br/> G1 X254 F1000 ;extend the buscket<br/> ;</em>end of pre-tool change gcode<br/> ; Start cleaning the filament before extraction<br/> M220 B ; turn aux v1.0.5<br/> M220 S100 ; change of loading tool</p> <p>;Begin PLA Tip shaping<br/> G1 E0.7644 F3639<br/> G1 E0.8248 F3926<br/> G1 E0.8483 F8483<br/> G1 E-15.000 F6000<br/> G1 E-24.500 F1200<br/> G1 E-7.000 F600<br/> G1 E-3.500 F360</p> <p>{if layer_num &lt; 1}<br/> M104 S[first_layer<em>temperature</em>[next<em>extruder]] ; toolchange set the extruder temperature - first layer<br/> {else}<br/> M104 S[temperature</em>[next_extruder]] ; toolchange set the extruder temperature - other layers<br/> {endif}</p> <p>G1 E20.000 F454<br/> G1 E-20.000 F303<br/> G1 E-35.000 F2000<br/> G4 S0<br/> ;End PLA Tip shaping</p> <p>;---------------;<br/> T[next_extruder] ;tool change<br/> ;<em>start the purge after changing the tool<br/> M107 ;turn off fan<br/> G4 S0<br/> G1 E12 F1440 ;filament support<br/> G1 E42 F1011 ;acceleration for nozzle loading<br/> G1 E6 F708<br/> G1 E40 F250 ;nozzle purge<br/> G1 E60 F300 ;nozzle purge<br/> G1 E3 F350<br/> M106 S255 ;turn on fan<br/> G4 S2 ;cool the filament<br/> G92 E0 ;reset the position of the extrusion<br/> {if layer_num &gt; 0}<br/> G1 E-[retract_length<em>toolchange</em>[next_extruder]] F1500 ;retract to avoid seepage<br/> {else}<br/> ; no retraction on first toolchange<br/> {endif}<br/> {if layer_z &gt; .25}<br/> M106 S51<br/> {endif}<br/> G1 X240 F5000 ;bucket go back home<br/> G1 X200 F12000 ;bucket go back home<br/> M220 R ; restore speed<br/> ;</em>end of tool purge gcode<br/> {else}<br/> ; no extruder change<br/> {endif}<br/> G1 X240 F5000 ;bucket go back home<br/> G1 X200 F12000 ;bucket go back home<br/> M220 R ; restore speed<br/> ;*end of tool purge gcode<br/> {else}<br/> ; no extruder change<br/> {endif}</p> <p>This G-code is a mix from G-code from JiVo and G-code from BigBrain3d.</p> <p>It's finished for the Software part and this installation !</p> <p><b> Slice and test !</b></p> <h3>Print instructions</h3><p>To print correctly (PETG 0.2mm 20% grid), please print these parts according to the last picture.
