From ab1eb70d1c70dd438f6b283503f7473cdc080d0f Mon Sep 17 00:00:00 2001 From: Kevin O'Connor Date: Sat, 11 Feb 2017 14:43:36 -0500 Subject: toolhead: Rework lookahead flush to be more stable during high cpu Change the lookahead queue so that it attempts to buffer at least buffer_time_high amount of moves when first starting a print. This helps ensure the buffer is normally always full. If the buffer falls below buffer_time_low then it is either due to the end of a print or because octoprint/klippy is unable to keep up. Change the code so that in this case the lookahead queue will attempt to gather buffer_time_high amount of moves before restarting movement. Update the default buffer_time_low to 1 second and buffer_time_high to 2 seconds. With the above changes a smaller buffer_time_high and a larger buffer_time_low are more practical.
