Hi @TomD ,
- The chain sag effect was quantifided at this post.
- Note that the parabola approximation of the catenary calculation already in the firmware was found to fit the need quite well.
- And the use of parabola approximation to correct sag was successfully used to acheive high accuracy cuts in that project
- For in depth coverage of the maslow tuning, you may want to review the Chain Length Calculation
- And if you would like to tune your maslow manually to explore its sensitivity, I recommend this advanced topic
