Prusa i3 rework (pcb) milling system

Description

The System Is Made To Switch Back And Forth Between 3D-Printing And Milling As Fast As Possible. It Consists Of The Holder For The Proxxon Flexishaft Micromot 110/P (Can Be Attached To A Dremel Too) And An Attachable Z-Axis Pushdown System. The Problem With The Prusa I3 Is That The Z-Axis Loosely Sits On The M5-Nuts And Only Moves Down Through It'S Own Weight. To Mill And Especially Drill Pcb'S For Example Some More Force Is Needed. The Pushdown-System Can Easily Be Attached Without Demounting The Axis. Two Lm8Uu'S Are Needed! Http://Www.Proxtools.Com/Store/Pc/Viewprd.Asp?Idproduct=35 Can Be Used To Mill And Drill Printed Circuit Boards For Example. Work In Progress, More Coming Soon!! Update: Project Closed, The Design Of The Prusa I3 With It'S X-Axis Just Laying On The Nuts On The Z-Axis Is Simply Not Suitable For Such Precise Milling. You Can Use It For Drilling As It Worked For Me Too But Precision On The Z-Axis When Forcing It To Go Down Is Just Not High Enough.
