Used to Repetier firmware and first time owning a board with the juice to run RepRap Firmware. I can't seem to find the location to modify the arm lengths directly. Michael Hackney post on the subject (http://www.sublimelayers.com/2018/03/mu ... parts.html) only talks about the global rod dimension and an X-Y scale factor. My issue is tower X and Z are close to the same required distance, but Y needs to be slightly longer to balance the kinematics. M665 just has global arm length.

Extra info for anyone who cares from my positional tolerance dial in:

- There is a slight change to Mike's scaling factor for X-Y dimensions in relation to the arm length. Based on the calculus the corrected L = original L * sqrt(measured X / true X) is more correct, but if you bought this kit the error is close enough that using a slightly worse convergence criteria doesn't really matter. If you want the exact converged values for you rods based on your delta radius use the excel at (https://www.thingiverse.com/thing:2528507/files) uses newton raphson method to converge on the answer for the non-linear equations. Necessary? Not at all but that never stopped me. Based off the work from PurpleSensation.

- If you set up your M665 and M666 command in your config to match the output of the M665 and M666 after G32 it makes it easy to copy and paste without messing something up. Ex) M665 L367.05 R204.042 H457.872 B140 X0.052 Y0.356 Z0.0 ; Set diagonal rod length, delta radius, homed height, printable radius, X twr deg adj, Y twr deg adj, Z twr deg adj
