Fixed minor bugs in planner. Increased max dwell time. Long slope bug stop-gap solution note. - Fixed the planner TODO regarding minimum nominal speeds. Re-arranged calculations to be both more efficient and guaranteed to be greater than zero. - Missed a parenthesis location on the rate_delta calculation. Should fix a nearly in-perceptible issue with incorrect acceleration ramping in diagonal directions. - Increased maximum dwell time from 6.5sec to an 18hour max. A crazy amount more, but that's how the math works out. - Converted the internal feedrate values to mm/min only, as it was switching between mm/min to mm/sec and back to mm/min. Also added a feedrate > 0 check in gcode.c. - Identified the long slope at the end of rapid de/ac-celerations noted by stephanix. Problem with the numerical integration truncation error between the exact solution of estimate_acceleration_distance and how grbl actually performs the acceleration ramps discretely. Increasing the ACCELERATION_TICKS_PER_SECOND in config.h helps fix this problem. Investigating further. 2011-09-18 13:36:55 +02:00			`// NOTE: Increasing this parameter will help remove the long slow motion bug at the end`
