Hello,
i have a problem with the Z-axis of my machine.
in the firmware i have these settings:
#define X_STEPS_PER_MM 80
#define X_STEPS_PER_INCH (X_STEPS_PER_MM*INCHES_TO_MM) // *RO
#define INVERT_X_DIR 0
#define Y_STEPS_PER_MM 80
#define Y_STEPS_PER_INCH (Y_STEPS_PER_MM*INCHES_TO_MM) // *RO
#define INVERT_Y_DIR 0
#define Z_STEPS_PER_MM 80
#define Z_STEPS_PER_INCH (Z_STEPS_PER_MM*INCHES_TO_MM) // *RO
#define INVERT_Z_DIR 0
this is ok for my machine which has three identical axis
Acceleration is set to off
When i use the ReprapHost or RepSnapper to move the axis manually it works all fine for the X and the Y axis,
but the Z axis only moves a very short distance.
When i try it with a serial Terminal i get following results:
G1 X10 F500 -> Moves in X
G1 Y10 F500 -> Moves in Y
G1 Z10 F500 -> Moves a few steps with lots of time in between
when accelartion is turned on:
G1 X10 F500 -> Moves in X wiht accelation
G1 Y10 F500 -> Moves in Y without
G1 Z10 F500 -> Moves a few steps with accelartion then steps slowly with lots of time in between
I tried to check if it is a problem with the electronics and changed the pins of the X and the Z axis in the firmware, but it was the the same there.
my firmware is the 20100806 from sourcforge and the electronics are those from techzone.
somehow the z-axis is treated different, but i cant find why? differnt timer or something.. ?
any ideas?
Thanks in advance
EDIT
I solved the problem.
with the firmware from reprap64bit it works fine. from 20100719
but dont know why
