Anet A8 - MKS GEN 1.4 mount
Description
Edit 1: Added Second Revision, R2 Raises The Mks Board Higher And Slides Half The Mosfet Under The Mks Board. Caution** This Revision Is Untested And Is Not 100% Guaranteed To Fit, If You Print This And It Does Not Fit Please Let Me Know So I Can Update Accordingly. Also Added R1 For A Mks Gen L Board, Also Untested. Please Provide Feedback If You Print These 2 Untested Parts To Change Them To Being Tested. Thank You. Added Step Files So People Can Modify Hole Positions For The Am8 Which I Do Not Have. Side Mount For The Mks Gen 1.4 Control Board To Mount On The Side Of The Anet A8. Also Includes A Spot For A Mosfet. Dual 40Mm Fans Over The Stepper Drivers To Provide Some Cooling. Included Are My Configuration.H And Configuration_Adv.H Files Used On My Mks Gen 1.4 That Runs My Anet A8. 2 Changes Are Needed To The Configuration.H File: - Define Baudrate 250000 //The Anet 1.0 Board Ran At 115200 Baud While The Mks Board Needs 250000 - Define Motherboard Board_Ramps_13_Efb //Same As Any Generic Ramps Board. This Is The Board I Use On My Anet A8 Being Run By A Mks Gen 1.4 Board. Next Is The Configuration_Adv.H File. I Made One Change Here And This Change May Not Be Applicable To You Please Read Below If This Is Necessary For Your Configuration And If It Isnt Then Disable This Line Using // At The Beginning Of The Line: Enable: Define Z_Dual_Stepper_Drivers The Anet A8 V1.0 Board Had The 2 Stepper Motors Driven From One Driver In Parallel Using 2 Plugs On The Board. I Didn'T Want To Do Any Rewiring With The Steppers To Have Them Both Motors Connected To The Same Plug. So I Opted To Use The Second Extruder Driver To Run Z2 Here Is How I Did My Motors: - X (Tmc 2100) - Y (Tmc 2100) - Z (Tmc 2100) - E0 (A4988) - E1 (Tmc 2100) *Note E1 Is Configured For A Dual Z Setup Hence The Use Of A Tmc 2100 Here Please Pay Attention To The M1A, M1B, M2A And M2B Position Between Different Stepper Drivers. Align These Up On The Stepper Driver Chips To The Same Position On The Mks Board. The Mks Board That I Got Didnt Have Labels On The Board So I Used A Multi-Meter And Measured The Continuity Between The Pins On The Stepper Motor Plug And The Pins In The Driver Socket To Find The Right Position. For Me They Turned Out To Be On The Same Side As The Motor Plug. Another Confusing Part Of Setting Up One Of These Boards Is Setting The Micro Stepping. I Didnt Touch The Micro Stepping In The Firmware As I Used The Same 1/16 Micro-Stepping As The Original Anet V1.0. Instead I Used The Jumpers Under The Stepper Driver Sockets. Note Every Driver Is Different But The Way I Did It Was Fairly Simple. For All The Tmc2100 Drivers Remove All Jumpers Under The Driver. This Puts The Motor In 1/16 Microstepping (Stealth Chop Mode) And For The A4988 Install All Jumpers For 1/16 Micro Stepping. Please Refer To Your Drivers Documentation To Be 100% Sure.
