Capteur remplacement location restored to DiscoVery position for full compatibility with this head: https://www.thingiverse.com/thing:2478810 Two free holes (with a 20 mm spacing) are available on the rear face of the left cart to add M3 screws for cable supports or a cable chain port. If using the 3-ventilo head, the Z travel is here re-increased to 220 mm, provided you use these high centers: https://www.thingiverse.com/thing:2748114 or those: https://www.thingiverse.com/thing:2538950 BOM: 9 x M3x8 screws --> for X axes brake brackets 10 x M3x12 + 10 x M3 nuts --> for palier bridging 4 x M3x8 screws --> for motor mounting 8 x M3x12 or M3x16 screws --> for trapezoidal nuts (see reference below) 2 x M3x30 screws --> for vertical axis of tensioner and horizontal tensioning screw. For this last function, shorter screws may be used depending on available travel. 1 x M3x14 or M3x15 screw --> for pulley axle... these screws are rare, so I recommend taking an M3x16 and cutting it. 2 x M3 nuts: one to embed in tensioner, the other for counter-tightening of tensioner. 2 x trapezoidal nuts: "SIZE 8": https://www.banggood.com/T8-Anti-Backlash-Spring-Loaded-Nut-For-2mm-8mm-Acme-Threaded-Rod-Lead-Screws-p-1111893.html 1 x Pulley: 4th type model "D" (Type D: <b>20T Pulley with tooth</b>): https://www.banggood.com/16T20T-GT2-Aluminum-Timing-Drive-Pulley-For-DIY-3D-Printer-WithWithout-Tooth-p-1099142.html or https://www.banggood.com/16T20T-GT2-Aluminum-Timing-Drive-Pulley-WithWithout-Tooth-For-DIY-3D-Printer-p-1220053.html?rmmds=detail-left-hotproducts__1&ID=514853&cur_warehouse=FR Edit 2015/11/21 For cable hook: - see Madness3D piece available here: https://www.thingiverse.com/thing:2658896 - or RGBA piece here: https://www.thingiverse.com/thing:2700544 For chain cable port hook: - see Moustache45 piece, available here: https://www.thingiverse.com/thing:2660582 - Or Erebius (3rd image, 2nd file): https://www.thingiverse.com/thing:2724297 - and/or Madness complete kit: https://www.thingiverse.com/thing:2730932
