Banding in z axis

Acceleration too fast, or maybe stepper driver needs tuning.

 

1. It's in the firmware, don't have time to outline it now, family is calling
2. Youtube has a lot of videos on how to adjust stepper drivers, here is one:

 

Configuration.h
Look for the following lines:

Code:

#define DEFAULT_MAX_ACCELERATION
#define DEFAULT_ACCELERATION
#define DEFAULT_RETRACT_ACCELERATION
#define DEFAULT_TRAVEL_ACCELERATION

Robo left all these settings at their Marlin Firmware defaults. In an ideal world we could accelerate our printers that fast, but in the real world I have found these values to be more realistic. Please note this is only my setup, you may need to play with these values a bit to get optimal printing speed vs. detail retention.

Code:

#define DEFAULT_MAX_ACCELERATION      {900,900,100,10000}
#define DEFAULT_ACCELERATION          600
#define DEFAULT_RETRACT_ACCELERATION  3000
#define DEFAULT_TRAVEL_ACCELERATION   3000

 

How fast it pulls filament from the hotend, not significant in any way as far as acceleration is concerned.
