x axis and y axis

x axis and y axis
September 03, 2015 02:05AM
I'm using RUMBA TAURINO and MARLIN.
I have calibrated the axis_steps_per_unit. The movement for z axis is fine, but for x and y axis, the stepper motor only move for 2mm, 10mm and 100mm.

Solution anyone?
Thanks in advance.

My default DEFAULT_AXIS_STEPS_PER_UNIT is {80, 80, 400, 499}, these settings makes the movement way off.

When I calibrate it to {5, 4.70, 250, 499}, the z-axis moves just fine, but not for x and y-axis.

How did you come to those numbers?

To me they seem to be way off, but my only experience in 3D printing is with a delta.
What type of printer do you have, and what size of pulleys (if used)?

EDIT: Also wich type of drivers do you use?

I'm using PRUSA i3.
The motor is a 1.8degree 2.5A NEMA17 stepper motor
Driver: Allegro A4988
•GT2 Timing Belts
•GT2 16-20 tooth Pulleys


I measure the actual travelled distance for 10mm.
(Default steps / Actual travelled distance) * 10mm

Is it correct or I used the wrong method?

You say 16-20 tooth pulleys? It's either 16 or 20. Assuming you're using 20 tooth pulleys, Repetier host belt calculator says 80 steps per mm, for 16 tooth 100 steps per mm.

Check the dip switches under the stepsticks. They should all be 'on'. This will set the micro stepping. All three switches at 'on' is 16x micro stepping. If somehow the dip switches are rotated 180 degrees by mistake, the dip switches should all be off. Just try flipping them the other way they are now and set steps per mm for x and y to 80:
DEFAULT_AXIS_STEPS_PER_UNIT is {80, 80, 400, 499}

You don't need to calibrate the X or Y steps per mm, just calculate it and it should be good. Just make sure microstepping is correctly set using the dip switches.

If micro stepping is turned off, the steps per mm is 5.5556. I highly recommend setting 16x micro stepping though.

It really is the dip switch under the stepper stick.

Thank You for the info and help.
