Anet A8 otpical Z Probe Bowden Mount MIX
Description
Remix Od Aeropics Bed Level System. Please Have A Look At His Design And How-To. Https://Www.Thingiverse.Com/Thing:2805327 This Design Is A Work In Progress And Must Be Treated As Such. I Will Post Updates To The Project As I Move Forward With Refining The Design. Please If You Have Any Comments Or Questions Please Post Them As I Would Like To Know If There Are Any Issues In The Design. Sept 27Th Update. The Flag Moved On My Last Design, This Was Due To Me Accidentally Hitting The Sensor Top Piece. Twisting The Rod And Breaking The Glue. Luckily The Flag Fell Down And The Head Continued To Move Up Rather Then Crash In To The Bed. There Are Two New Pieces The New Servo Mount And The New Main Mount. Have Slots Cut In Them To Allow For The Removal Of The Rod So That The Flag Can Be Glued To The Rod Better. These Are Minor Fixes And On My Unit I Simply Cut The Notches In The Mounts To Allow For The Rod To Be Removed. Other Then This One Issue The Printer Has Been Used Almost Daily And The Bed Leveling Is Giving Great Results. Aug 25Th Update. The Bed Levelling Is Working Really Well Now. No Issues At All With The Auto Bed Levelling And First Layer Print Quality Has Come Up. I Changed My G-Code To Run Heat The Bed To 60C Before Doing The G29 For Bed Levelling. This Helped Me Get Past Some Really Wierd Results On The First Layer. I Recommend That You Clear Your Eeprom, Then Flash The Anet A8 Opti Boot Loader If You Have Not Yet Done This Yet, Then Flash Marlin 1.1.9. I Use Octopi So My Gcode Start My Be Different Then Others. So My Settings May Not Work For Everyone. My Settings Follow, If Anyone See'S Any Issues With The Settings Please Get Back To Me Right Away. The Dots Are To Stop Thingiverse From Using The Number Sign. Also General Disclaimer, I Am Not A Professional In Any Of This, Use These Settings At Your Own Risk.

If You Find Any Error'S Please Tell Me Right Away. If You Have Better Ways To Do Things Post Em As Well. Make Sure If You Build One To Post The Make. I Am Super Happy With How Well This Setup Is Now Working. Hope This Helps Get Guys Bed Leveling With A Super Affordable Setup. Also At This Point The Servo-Optical Switch Combo Has Outlasted The Proximity That I Tried To Use Before. Updated The Servo Mount Screw Hole Positions To Move The Servo Back Slightly. Also To Work With This Setup You Will Have To Move Your X-Axis Switch Over By About 10Mm So That It Contacts The Side Of The Frame.
