Alternative Idlers that allow the usage of "Full-Figured" toolheads without the loss of travel at the front of bed.
These idlers were developed to allow the usage of wider toolheads with the Voron V2, better align the tensioning screw to the centerline of the idler shaft, add guides to the parts to allow them to interlock and provide a robust tensioning system, and streamline the process of making fine adjustments to tensioning. I am currently running these on my machine and have not seen any performance issues. At this point, I am planning to open them up to more broad beta testing.
The idler design is ambidextrous to allow simplified printing. All parts are converted to stl in optimal printing orientation.
BOM: 2 ea. 5mm OD x 45mm L pins - may need to be polished down to fit the bearings depending on source. 4 ea. F695 bearings 4 ea. 0.5mm thick 5mm shims 2 ea. M3x35mm length SHCS - Stock 40mm may be run if not using the bolted door hinge mod. 2 ea. M3 flat washer 2 ea. M3 nut 2 ea. Voron - standard heat set 2 ea. M3 x 16 SHCS
These components will soon be offered as a kit by https://formosissima.com/products/other-v2-idlers-kit
This mod also requires that you run https://github.com/VoronDesign/Voron-2/blob/Voron2.4/STLs/VORON2.4/Gantry/%5Ba%5D_z_belt_clip_lower_x4.stl on both top and bottom as belt clips, so that the design is not handed.
"Other" Idlers vs. stock V2.4 idlers
Be sure to fully insert the m3 heat sink so that it doesn't interfere with the bearings!
