Remix of the nice Z Orbiter v2, now also for the Mini Bear.
Normally all parts for the Mini Bear have to be mirrored when originally designed for the MK3. This time it could only be mirrored partly, since the Orbiter is not symmetrical.
It's not my best work, had to hack my way through here and there (no step files), but it all fits.
Only for the (original) V6 hotend.
I had to play quite a bit with the settings and came to these, which prints fine on my Bear:
Current: E850 (M906 E850)
Extrusion: 1.00
Esteps: 690
Linear advance: K0.04
machine_max_feedrate_x = 120
machine_max_feedrate_y = 120
machine_max_feedrate_z = 12
machine_max_feedrate_e = 60
machine_max_acceleration_x = 1250
machine_max_acceleration_y = 1250
machine_max_acceleration_z = 200
machine_max_acceleration_e = 600
machine_max_acceleration_extruding = 1250
machine_max_acceleration_retracting = 1250
machine_max_jerk_x = 7
machine_max_jerk_y = 7
machine_max_jerk_z = 0.4
machine_max_jerk_e = 8
Some settings could be higher, but this is a nice baseline to start from.
