Sequence contains no elements #1
Description
It appears that input with an absolute value greater than or equal to 2 for either "Baseline Adj" or "Arm Adj" reliably gives the error "Sequence contains no elements" (see comments at the Drawbot project page for others reporting the same problem) This prevents accurate calibration of TRS Drawbots per the instructions; e.g. the sample "nudge" calibration values given in the instructions (-2, +3.5) do not work, nor do other values outside an apparent +/- 1.9 (or so) range.
Smaller baseline and arm adj value increments such as 0.5 or 0.01 do affect .wav file output (and hence Drawbot output) but it is inclear what conversion factor between degrees of skew at calibration and numeric input in the WAVE generator is required.
Evidently something in the code has changed between the time the screenshots in the instructions were produced and the current release available on github.
If this issue could be addressed it would be much appreciated. Several of us have very much enjoyed building Drawbots and hope to be able to produce calibrated/unskewed output with them! This is my first time reporting an issue on gitbut, just as it was my first time building anything with servos, so I'm enjoying the learning process. If there's any additional information I can contribute here to assist please let me know.
