Pull request1 #15

Open jgilmore opened 13 years ago

It's written in the commit comment, but basically I noticed that if I ran two moves: G1X10 G1X10 I could hear the steppers hesitate between the moves. This change removes that hesitation, at the price of a possibly much longer-running timer interrupt.

This is because next_move is now tail-recursive when there are zero step moves queued.

Also it's not yet perfect, see commit notes for my reflections on the timer status across moves.

Defining "bang-bang" will allow debugging to be built for a 168 chip. If we're not using endstops, we shouldn't require that they be defined.

This was closed? Did I do that by mistake or did somebody mean to close this pull request?

hi, is this still relevant to the current codebase? Without my motors set up I can't tell

I don't know. With my laptop broken I can't tell :)
