I am building an extruder / hotend combination to be used with 2.85 mm filaments.
The extruder I chose is QR Extruder from Bondtech which comes with a stepper motor, with an integrated planetary gear system and a reduction of 5.18 to 1.
The motor's specification states that it has a backlash of less than 1 degree.
I have contacted the manufacturer but I could not get a more specific number.
Here is what I'd like to know (i.e., my question clarified) :
- How does this < 1 degree backlash translate to pushing filament through the hot end?
- Once the extruder steps are calibrated, can it cause artifacts on the prints?
- Can linear advance (Marlin) or pressure advance (Klipper/Duet) make up for this < 1 degree backlash of the planetary gear system?
