Jerk And Accl Issues
November 11, 2016 08:03PM
Not sure what happened but recently I upgraded my X axis to a V-Slot from a bearing style. It has been working and printing fine. This morning I went to print something and it behaves very strange. When printing the perimeter it will come to nearly a stop before changing directions.And when not printing and moving to print again slow as heck. I am not sure why as it was fine below are my acc and jerk settings from my config file
Hope someone can help this is annoying as heck.

Also see a video of what it does here

#define DEFAULT_MAX_FEEDRATE {300, 300, 5, 25} // (mm/sec)
#define DEFAULT_MAX_ACCELERATION {3000,3000,100,10000} // X, Y, Z, E maximum start speed for accelerated moves. E default values are good for Skeinforge 40+, for older versions raise them a lot.

#define DEFAULT_ACCELERATION 3000 // X, Y, Z and E acceleration in mm/s^2 for printing moves
#define DEFAULT_RETRACT_ACCELERATION 3000 // E acceleration in mm/s^2 for retracts
#define DEFAULT_TRAVEL_ACCELERATION 3000 // X, Y, Z acceleration in mm/s^2 for travel (non printing) moves

// The speed change that does not require acceleration (i.e. the software might assume it can be done instantaneously)
#define DEFAULT_XYJERK 20.0 // (mm/sec)
#define DEFAULT_ZJERK 0.4 // (mm/sec)
#define DEFAULT_EJERK 5.0 // (mm/sec)

What speeds are your slicer settings at. The firmware setting look fine to me.

Check the above settings in the eeprom (if enabled)

After flashing the Firmware like 40 more times I finally got it to work proper. I don't know why it wasn't working the first flash. But now it is. On to the next problem.
