FolgerTech Kossel hotbed adjustable mount. Easy to calibrate.

Description

I'M Tired Of Calibrating My Folger Tech 2020 Kossel Using Z-Probe. Tried Both - Marlin And Repetier. They Calibrate, But I Didn'T Like The Final Results. The Stock Z-Probe Is Too Far From The Tip (X-Y Offset) And Even Slight Effector Tilt Return Very Inaccurate Values. So, I Decided To Make My Own Adjustable Hotbed Mount Using Spare Screws From Printer Kit (3 M3X25, 3 M3X15, 3 Nylock M3 Nuts, 3 Washers And 3 M3 T-Nuts For 2020 Extruded Profile), Simple Sketchup-Made Mount (Printed Using Petg) And 3 Springs That I Found In $4 Homedepot Spring Kit (Http://Www.Homedepot.Com/P/Everbilt-Spring-Assortment-Kit-84-Pack-15642/202045461). What A Difference! It Took Only 15 Minutes To Calibrate The Installed Bed With Very High Precision. Tip: Use Small Drill Bit (1.5Mm-3Mm Diameter) Instead Of Paper For Initial Calibration - It Will Give You Some Room Between The Nozzle And Bed And Will Prevent Head Crash. Measure It'S Opposite (Non-Working) End (Let'S Say It'S 1.98Mm), Set Z Height To 1.98Mm, Move The Head As Close To The X Calibration Screw As Possible And Adjust It So The Drill Bit Will Roll Just Slightly Touching The Tip. Repeat For Y And Z. Repeat The Procedure, If Needed, Then Start Adjusting Delta Radius. Repeat With Paper Test To Fine-Tune, If Needed. Finally, I Dismounted The Probe (Here Is The Replacement Mount To Add Extra Fan Http://Www.Thingiverse.Com/Thing:1123295) And Will Never Use It Again... Hardware Calibration Rules. Ps: To Avoid Mess With Slicer And Make Smooth Transition During Printing From Hex-Nut Hole To M3 I Designed The Thin Wall, So Short Bridges Over Hex-Nut Hole Will Do The Job Pretty Well. You Need Just Puncture This Thin Wall Using Small Screwdriver Before Inserting M3X25 Screw.
