Hello all, I am making the beautiful robotic arm. Only I have a question. I would like to replace the stepper motors J4 and J6 with servos. For example, the TD-8320MG. They can handle 20 Kg. drawing work and 3D printing work is no problem for me (and I also want to share that .stl when it's done). Only I don't know anything about Arduino programming, I know how to upload the firmware, but not how to program. Does anyone know or can someone change the Arduino code so that instead of stepper motor control becomes a servo motor control. it seems quite simple to do, but for me it is just too difficult. If anyone doesn't mind changing Arduino code, I'll exchange the .STL files for everyone to try. Friendly greeting Aldrik Koster
