Orbiter 1.5 direct-drive extruder mount for Prusa Mini

prusaprinters

<p>I wanted to add a direct-drive extruder to my Prusa Mini... so I did. &nbsp;The Orbiter works very well in this role, but it cannot print TPU in its current iteration. &nbsp;Still, it's a great upgrade to the Prusa Mini, and pretty easy to install.</p><p>The mount replaces Prusa's existing fan spacer, adding a platform to the top of it to put the orbiter on.</p><p>&nbsp;</p><p>To mount, you need:<br>2 M3x10mm flat-head screws - to mount the orbiter to the mount<br>2 M3 nuts - to mount the orbiter to the mount<br>1 M3x10mm screw - to hold the mount onto the mini's heatsink<br>56mm of 4mm PTFE or Capricorn tubing - the length needs to be adjusted pretty exactly. &nbsp;You can fine-tune by adjusting the heatbreak, but remember to recalibrate the PINDA probe.</p><p>I also used crimpers and made up a locking 4-pin plug for the orbiter, and zip ties to hold the wires together.</p><p>In my Mini's start gcode, I've added:<br>M92 E655 ; set E steps per mm for the Orbiter extruder<br>M906 E300 ; set the extruder to 300ma for the Orbiter extruder. &nbsp;350 is the default, can bump up as needed.<br>M900 K0.03 ; set the linear advance for the Orbiter</p><p><br>I made a video of the install here: <a href="https://youtu.be/f6VlFAkn_5I">https://youtu.be/f6VlFAkn_5I</a><br><br>And there's a 2.0 update here: <a href="https://www.prusaprinters.org/prints/136978-orbiter-extruder-20-mount-for-prusa-mini">https://www.prusaprinters.org/prints/136978-orbiter-extruder-20-mount-for-prusa-mini</a></p><p>&nbsp;</p>
