<p>The Cable Chains on the MP Maker Select V2 are not being properly utilized in factory form.</p><p>Chains need to be constrained, so that they ‘unroll’ gradually across their motion, to spread cable flex out along its length and extend lifetime.</p><p>In factory form, the ends of these chains are freely pivoting, which focuses stress on the ends of the cables.</p><p>&nbsp;</p><p>These brackets reroute and guide the cable chains, for longer service life.</p><p>&nbsp;</p><p>Note the end mounting links of each section of chain need to be unclipped, and reversed to face opposite direction before bolting onto brackets.</p><p>&nbsp;-while you have the ends unclipped, transfer 1 link from the vertical to the horizontal run (just snake it along the cables).&nbsp;</p><p>Also note that the horizontal run of cable now mounts to the Backside of the extruder head. The metal bracket that it normally bolts to is replaced with a printed part. the X limit sensor will also be remounted. &nbsp; as a bonus, routing out the backside adds clearance to the top of the printer frame.</p><p>&nbsp;</p><p>Hardware needed:</p><p>3mm x 12mm bolts &nbsp;-length matters! don't want the ends to intrude into moving parts</p><p>3mm nuts with 5.5mm wrench flats</p><p>Re-use of pan head bolts already holding cable chain ends.</p><p>&nbsp;</p><p>Sorry for the terribly hard to interpret photos. My printer doesn't live in a photo studio, and its not really practical to move it around.</p>
