Z Axis doesn't moving up during printing

Hello, I've got a little problem here. I've test my axis in manual control and everything runs perfectly, but when I start my printing, the z-axis doesn't moving up at all.
I've read a post in a forum about the same problem and the solution is to change the acceleration and the feedrate of the z-axis. Therefore, I change it to the value which is mentioned in the post.

#define DEFAULT_AXIS_STEPS_PER_UNIT {80.00,80.00,4000.00,606.09}
#define DEFAULT_MAX_FEEDRATE {500, 500, 2, 25}
#define DEFAULT_MAX_ACCELERATION {9000,9000,100,10000}

After changing the value into the number above, the z-axis moving up at first but when the z-axis reach the 3rd layer, the axis doesn't move again. May I know what might be the cause?


  • Do you have eeprom enabled? If so then changing the file will not matter as it is read from eeprom.
  • If not eeprom related, ask the experts in a Marlin forum:-) Might also be endstop related or friction is getting too high.
