Resetting axes between layers
About a week ago, Adrian noticed the difficulties I was having with Tommelise's positioning and messaged me...
Forrest - do you re-zero X and Y between layers? That takes very little time, and can significantly reduce drift.
My initial reaction was that as slow as Tommelise runs re-zeroing between layers would add enormous amounts of seconds to a print job. Eventually, I worked out the numbers and saw the sense of what he was suggesting. Since then I've discovered that while re-zeroing between layers takes but a little extra time, whacking Tommelise into shape to be able to do that is a non-trivial job, given the state of some of the systems in Tommelise that are required to do that job correctly.
