Here is the rewritten text in American English, without any foreign characters or extra comments: Stronger idler arm for "Yet another extruder filament drive" (Extruder for Thing-o-Matic and earlier Makerbot Industries printers) Changes: * Thicker front side * Proper names assigned to parametric steps * Long hole enables pressure bolt at an angle * Wider long hole allows M4 bolt free movement * Round hole provides strength with bearing * Reshaped sides add strength * Wider hole for 608Z bearing * Wider axis hole for 608Z bearing Stronger body: * Thicker idler arm * Larger base plate attaches to idler arm * Wider mounting nut holes * Many parametric operations receive names * Long stepper motor mounting holes align perfectly * Mounting blocks are ever so slightly smaller * Longer extruder mounting bolts allowed than required Blog postings: marcuswolschon.blogspot.com/2012/12/testing-sailfish-firmware-and-new.html marcuswolschon.blogspot.com/2012/11/improving-gaerisls-extruder.html
