There are two parts to the Mini-X-End (v3) splitting the part in two: a fixed part to lock the X axis and a moving part for the idler, allowing an easier tensioning of the belt, which can even be done on the fly!
Who hasn’t been there with their Prusa mini? Binding on the end of the X arm? It happens all too frequently and is one of the major annoyances with the Prusa Mini. What we have here is a redesigned Mini X End. When you tighten the 2 screws on the Mini End, you are creating a torsional interference on the 2 8mm Rods. They are not in alignment and because of this, no matter how hard you try, you will get binding. The new Mini-X-End (v3) allows you to precisely control both belt tightness and torsional pressure on the 8mm rods. THe threaded inserts allow for solid tuning of the belt. No more binding.
But wait, there’s more!
Further, in the design, you now no longer have to take your entire X-carriage apart to adjust or replace the belts, the bearing housing now is no longer captured, allowing you to pull the 624h bearing out from the rear of the Mini End!
All required hardware provided, simply swap in your new Mini-X-End (v3), Tighten down the m3 bolts and you are on the road to smooth alignment on your X-Axis 8mm rods!
• Stiffer in all directions, less twisting
• better long term stability (should hold alignment better)
• can take out the Pulley easily (if you want to change something on the x carriage you don’t have to remove the X-End)
• less wear as all screws have metal to thread into.
All parts are included and assembled, including bolts and 623H pulley!
(Mini End is printed in Prusament Orange or Prusament Black to exactly match your Mini!)
