Compact Opto Servo Probe V2 (SG 37 servo)

A New Compact Opto-Servo Probe Takes Shape. I've Taken the Lead from Japim's Idea of Using a Lightweight Micro-Servo, Scaling Down to BL Touch Height and Adapting the Flag and Spring from My Previous Compact Opto Servo Probe. Assembling Instructions Can Be Found in the Pictures Provided. Note That the Spring Is Optional - I Didn't Use It in the Video. Wiring and Firmware Modifications Remain the Same as Explained in the "Compact Opto Servo Probe" Guide. The Accuracy and Repetition Capabilities Are Identical to Those of the Previous Version, with a Standard Deviation of Approximately 0.0015. To See the Short Videos Demonstrating Accuracy and ABL Testing, Visit https://youtu.be/_hWpGgZ0SwI and https://youtu.be/2ZZLR1Gbfbo Respectively. A 3D Model View Is Available at https://3dwarehouse.sketchup.com/model/27319797-e0c6-4491-bd8e-cd20488220fc/Compact-opto-servo-probe-V2, Where I Designed It Using Designspark Free and Exported to a STEP File. As of 15.04.2020, Configuration.h and Configuration_adv.h Have Been Added for Marlin 2.0, Anet 1.5 Board, and 12864 Display Users. To Enable Linear Advance with #define DISABLE_M503 Active in Configuration.h, Simply Activate It in Configuration_adv.h. Additionally, on 24.04.2020, a Base Was Designed to Accommodate a 12mm Thick Opto Switch (including PCB).
