Making a new mounting bracket for the proximity sensor to replace the fragile 3D printed part supplied with the kit.<br /><br />Type A Machines has released a new bracket design that relocates the sensor to the left side of the extruder. I think I prefer the sensor in the original location, it's easier to access with the printer enclosure in place. <br /><br />TAM community forum thread with ABL details:<br /> <a href="https://typeamachines.zendesk.com/hc/en-us/community/posts/115018310363-Auto-leveling-consistency-and-BuildTak-Issue-" target="_blank" rel="nofollow">https://typeamachines.zendesk.com/hc/en-us/community/posts/115018310363-Auto-leveling-consistency-and-BuildTak-Issue-</a><br /><br />Big thumbs up to Duncan for the excellent sensor holder design. You'll need a scrap of stainless steel or aluminum sheet metal, an M12x1.0 and M3x0.50 thread cutting tap. <br /><br />Marlin firmware modifications and uploading to the Rumba board in this video:<br /> <a href="https://youtu.be/s1P6enF_5dk?list=PLpY2FP1a9tisfyeH6pMvax6YHcbzAiKvj&t=252" target="_blank" rel="nofollow">https://youtu.be/s1P6enF_5dk?list=PLpY2FP1a9tisfyeH6pMvax6YHcbzAiKvj&t=252</a><br /><br />Be sure to rate, comment and share<br />And as always, thanks for watching<br /><br />Intro:<br />Louisiana Fairytale by Austin Rogers<br /><a href="http://drfiddle.com/show_tune.php?id=94" target="_blank" rel="nofollow">http://drfiddle.com/show_tune.php?id=94</a><br /><br />Soundtrack:<br />Prelude No. 1 by Chris Zabriskie is licensed under a Creative Commons Attribution license (<a href="https://creativecommons.org/licenses/by/4.0/" target="_blank" rel="nofollow">https://creativecommons.org/licenses/by/4.0/</a>)<br />Source: <a href="http://chriszabriskie.com/preludes/" target="_blank" rel="nofollow">http://chriszabriskie.com/preludes/</a><br />Artist: <a href="http://chriszabriskie.com/" target="_blank" rel="nofollow">http://chriszabriskie.com/</a><br />...<br /><a href="https://www.youtube.com/watch?v=1vEnw33LDmM" target="_blank" rel="nofollow">https://www.youtube.com/watch?v=1vEnw33LDmM</a>
