Hi,

i need some help . I built my second 3d printer using ultimaker controller board.

My first printer used rods for x and y.

This printer works on v rails ( sliders that move with wheels on the v rail extrusions ) instead of rods. Everything is working fine, except i noticed that i tried to

print a test part, it is a square with rounded corners which consists of 4 identicalcircles, and the circles do not print correctly.

Please see the image attached.

I have searched on the web for possible solutions.

i have tensioned the belts, i have calibrated the steps for the motors.

i am using a 30 tooth gear with 2mm gt belt, the steps for x and y are 53.33

The bed is leveled properly, i use fuller gauges to level properly.

i don't know what else i can do.

Can i implement something within the firmware ?

I am stuck, i really don't know where the problem is.

what can be the issue i am encountering ?

I would appreciate your comments, anyone ??

    You have play in your X and Y axis. Meaning that if it changes direction, it won't change instantly, but needs a bit of movement from the motor before the head starts to move.

    I could tell more if I know what kind of machine you build, feel free to share a picture of that as well.

    (On an Ultimaker this is usually because of lack in tension on the short belts)
