M376 tapering documentation clarification



  • The documentation for M376 (https://duet3d.com/wiki/G-code#M376:_Set_bed_compensation_taper) says:

    This command specifies that bed compensation should be tapered off over the specified height…

    Which I misinterpreted the first 5 times I read it as meaning the tapering begins at the height setting (thinking "over" meant "above"). Of course that makes little sense, and reading the rest of the paragraph clears it up. But I'd like to propose changing the wording to something like:

    This command specifies that bed compensation should be linearly [I'm assuming] tapered off over the range z=0 to z=H…

    Thanks. I've updated the text for M376. Please re-post if you still think it isn't clear.



  • Much clearer, but the first sentence still says "bed compensation should be tapered off over the specified height." I think what throws me is the word "height" - I think "range" would convey it better. One last suggestion and then I promise I'll shut-up and stop wasting your time! 🙂

    This command allows the bed compensation to linearly taper off over the range between Z=0 and Z=H, so that full bed compensation is applied at Z=0 and no bed compensation is applied when Z is at or above H. If H is zero or negative, tapering is disabled so compensation is performed throughout the entire print.

    I used to manage a group of engineers who had to do a fair amount of technical writing. I'm pretty sure they hated me (at least when they were writing datasheets). 🙂
