Here's my re-mix on the F.Tobler robot arms - a significant upgrade over the original Tobler design. The majority of the files remain unchanged, with only the new components included here. Below are the key changes I've made: * Improved wiring for hiding motor cables. * Fitted the mini-stepper motor board inside the lower shank. * Swapped out the endstop plate for a home switch setup. * Added two home switches to the upper and lower shanks, as shown. * Created an outlet for cables under the new endstop module. * Built a custom RAMPS case using a 5cm PC fan. * Upgraded the gripper motor input from 5V to 12V for improved response. * Modified the gripper fingers for holding pens and marbles. You can check out my demo video here: https://youtu.be/V9V-t0cJFI8. I've also included links to YouTube videos showcasing the arm's capabilities: https://www.youtube.com/watch?v=HXhPVoDxrdw https://www.youtube.com/watch?v=j5DSirqxDHk To purchase the necessary parts, visit these Taobao links: * Long cable mini-motor: https://world.taobao.com/item/522575740869.htm?fromSite=main&spm=a1z09.2.0.0.k7UjIt&_u=g2bdisfs7990 * End stops witch: https://world.taobao.com/item/37170722351.htm?fromSite=main&spm=a1z09.2.0.0.k7UjIt&_u=g2bdisfsd8af * RAMPS: https://world.taobao.com/item/522889564750.htm?fromSite=main&spm=a1z09.2.0.0.k7UjIt&_u=g2bdisfsd0f8 I've included the self-test Ino program for everyone, which you can use to reset the arm to its home position using the endstop switches - just check out my YouTube video below: https://www.youtube.com/watch?time_continue=4&v=j5DSirqxDHk
