While usable, this is still a WIP
I designed this to replace the 8mm smooth roads on my Hesine m505 with 400mm MGN12 linear rails and 10mm wide belts. This design incorporates a floating X axis idler to help reduce Z wobble artifacts. Currently it is using an old fan duct design and it is also compatible with my Z endstop adjuster.
I will later update this for use with 450mm rails (what I should have ordered), and different pulley sizes.
Note that this is for printers with a spacing of 22mm between lead screw and smooth rod centres.
LM10 version now availiable.
2016/11/15 Now with even more overkill. SFU12 ballscrews and LM10 smooth roads.
BOM;
mk8 extruder idler, spring and supplied M3 bolts.
