Hello,
I recently purchased the Einsy Rambo from Ultimachine. I think I've gotten the X and Y axis motors tuned and ready for a test print. My problem is the Z axis. I have continual grinding noise (I think Thomas Sanladerer refers to what I'm experiencing as resonance). Here are my current settings:
#define DEFAULT_MAX_ACCELERATION { 150, 100, 30, 2000 }
/**
* Default Acceleration (change/s) change = mm/s
* Override with M204
*
* M204 P Acceleration
* M204 R Retract Acceleration
* M204 T Travel Acceleration
*/
#define DEFAULT_ACCELERATION 2000 // X, Y, Z and E acceleration for printing moves
#define DEFAULT_RETRACT_ACCELERATION 3000 // E acceleration for retracts
#define DEFAULT_TRAVEL_ACCELERATION 3000 // X, Y, Z acceleration for travel (non printing) moves
I've followed
this tutorial to set the X&Y. I've lowered the DEFAULT_MAX_ACCELERATION to below 10 without any luck. Does anyone have any suggestions on what I should do to get this printer working? Or is tuning the Trinamic drivers different than the standard drivers?
Any input is greatly appreciated.
