• My apologies for the long delay, I didn't have access to the machine over Christmas, so I just had a chance to work on it today.  As you guessed I was using a really high step/mm setting for the xy axis.  The  ball screws on the x-y table are 4 mm/r…

• Thankyou for the clarification on Jerk.  I think I understand what you're saying, but I'm not sure I'd pass a pop quiz on it. It may just be that this thing is big and slow.  The really strange thing to me is that the y axis of the machine uses a m…

• I'm sorry I'm not following.  I have adjusted the jerk quite a bit to try to get the best/fastest performance out of the printer for a given, combination of jerk, acceleration and velocity settings.  I'm a little unclear as to what the jerk setting …

• Z acceleration is the constant acceleration of gravity.   The x and y accelerations are from the movement of the table itself.  The way the machine works is that the hot end is fixed in the x and y axis and the heated bed moves underneath it in the …

• Here is a link to the .csv file with the acceleration data in m/s^2.   https://dl.dropboxusercontent.com/u/54812743/2nd%20print%20with%20video-acc.csv Let me know if you have trouble accessing this file.  If it works I'll put links to the other rel…

• Thanks for the response and I'm Sorry for the delay in responding.  In previous post I'm using transient to mean "unusually large" or outside of the normal range of accelerations.  Rereading my post It should say      "I have measured transient acce…

• Thankyou, for the quick response. So let me see if I"ve got this straight in my head.  The feedrates set in the printer configuration get multiplied by the slider factor divided by 100.  So that if the feedrate in the manual movement tab is set at 1…
