Coleman Benson 27.1 10 The Lynxmotion [[doc:ses-pro.lss-pro.WebHome]] have multi-turn capabilities which require that an origin (zero) angle be configured for each application. In theory the origin can be anywhere between 0 and 360 degrees, but to ensure the physical arm's angles match the angular commands sent from software, a known "origin" or "zero" angle for each servo must be accurately set. Using the [[doc:ses-pro.lss-pro.lss-p-configuration-software.WebHome]] and positioning the arm to a known, reproduceable position will allow for this, regardless of the "random" angle at which each joint was assembled. This requires a flat surface onto which the assembled arm can be placed.

Coleman Benson 27.1 16 Lay the arm flat on the surface, ensuring that the servos in the elbow and wrist are fully in contact and flat against the surface as shown in the images below.

Coleman Benson 27.1 18 This procedure can be done with or without the base plate connected, but assumes the arm's base is connected to J1.

20 Two joints won't be constrained in this position and therefore cannot be accurately zeroed: Joint 1 (base) / ID1 and gripper (rotation) Joint 6 / ID6. It is left to the user to center these servos as needed using the procedure below.

Coleman Benson 27.1 56 Now that the angle of joints 2 to 5 are known and absolute, the arm will be moved a vertical "default" position. For this, only two joints need to be moved: J2 / ID2 and J3 / ID3.

Coleman Benson 27.1 58 As mentioned above, the known angles between J2 and J3 and J3 and J4 will differ if the [[doc:ses-pro.ses-pro-parts.ses-p-a-bap-kt.WebHome]] is installed or not so be sure to use the correct angles below for your particular application / mounting.
