[gcode_macro CUT_FILAMENT]
description: Cut filament by pressing the cutter on a fixed pin with a horizontal movement.
description: Cut filament by pressing the cutter on a fixed pin with a horizontal movement. Based on Thiscams macro but updated to work with HHv2
#Modify the below settings in mmu_parameters.cfg
#toolhead_sensor_to_nozzle: 62 this will need to be reduced to compensate for the extra filament letf in the nozzle so probably to 5 to 15mm shorter based on the variable_retract_length: below.
#force_form_tip_standalone: will need to be set to 1 and all tip forming settings will need to be disabled in your slicer including ramming.
#slicer_tip_park_pos: will need to be set just above the cutter slot.
# Distance to retract prior to making the cut, this reduces wasted filament but might cause clog
# if set too large and/or if there are gaps in the hotend assembly

# Therefore, for a cut:
# - We first make a fast move to accumulate some momentum and get the cut blade to the initial contact with the filament
# - We then make a slow move for the actual cut to happen
