* kin_extruder: Convert pressure advance to use "weighted average"Kevin O'Connor2019-12-201-19/+54
| | | | Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* itersolve: Rename scan_pre/_post to gen_steps_pre/post_activeKevin O'Connor2019-12-101-1/+2
| | | | | | Rename the variables to make it a little more clear what they do. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* kin_extruder: Apply pressure advance in kin_extruder.cKevin O'Connor2019-12-081-58/+23
| | | | | | | | Implement the pressure advance calculations while performing the definitive integral calculations. This simplifies both the extruder.py and kin_extruder.c code. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* kin_extruder: Move integration code from trapq.c to kin_extruder.cKevin O'Connor2019-12-081-0/+65
| | | | | | | Move the code that calculates the definitive integral to the kin_extruder.c file. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* extruder: Initial support for "smoothed pressure advance"Kevin O'Connor2019-11-211-56/+45
| | | | | | | Support averaging the extruder position over a time range to "smooth out" the velocity changes that occur during pressure advance. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* trapq: Use separate 'move' entries for accel, cruise, and decel phasesKevin O'Connor2019-11-061-20/+39
| | | | | | | | Only track a single acceleration movement in a 'struct move' instance. Break the classic trapezoid movement (accel, cruise, decel) into three separate movements. This simplifies the calculation logic. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* trapq: Remove move_fill()Kevin O'Connor2019-11-061-5/+9
| | | | | | | Now that all callers use the trapq system to queue moves, it is no longer necessary to individually allocate and fill a 'struct move'. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* extruder: Convert step generation to use trapq systemKevin O'Connor2019-11-061-1/+3
| | | | Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* trapq: Add new trapq.c file with code for trapezoidal velocity handlingKevin O'Connor2019-11-061-0/+1
| | | | | | Move the "struct move" code from itersolve.c to new file trapq.c. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* itersolve: Rename calc_position to calc_position_cbKevin O'Connor2019-11-061-1/+1
| | | | Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* extruder: Convert to using iterative solverKevin O'Connor2018-06-201-0/+54
