I was afraid that the processor was the problem but it raises a question.
Why do the x and y axis always run smoothly when they have the same number of steps per meter and are running at relatively the same rpm?
Thanks again

As I looked up the steps per meter number for the extruder I realized that it is very close to the number steps per of the x and y axis. The number that I am using for the extruded is 181486. I am not sure that this is the issue any longer.
I am using:
200 steps per revolution motor
1/32 stepper driver
10.35mm diameter drive pulley
1.75mm ABS (I add half the diameter of the filament to the driv

I do not want to hijack this thread but I have a question that it sounds like people here might be able to answer. I have put a direct drive extruder on my prusa with Sanguinololu running teacup and with the after setting a small amount of steps per meter of extrusion the stepper motor runs in large steps, very jittery, to the point of creating small bulges on the exterior of my parts. I have bee

I was wondering about the stepper motor itself. I actually switched out the pololu board with the new 1/32 stepper board from pololu and the problem still exsists, but only a teensy bit better (and I might be imagining that, there is no real way to measure the difference)
I may have to switch around some stepper motor wires tonight and see if a different motor will create better results.

I have a prusa mendal that I am controlling with a sangunololu. I have got it working quite well however the number of extruded steps that I enter into the configuration file is about 4x lower than it should be. It is like I have the pololu set to run at 4 steps instead of 16 steps. Below is what I have done. I recently changed to a direct drive extruder and now my print quality is lacking. Any s
