Hi krzypar,

Please check if the microstep resolution on two stepper motor drivers were set to HHH (pull the small white switches on each driver to H side)

Actually,the mScara is not very good to draw a circle, drawing rectangle is better for it.
While, you still can adjust the length of the ARM B to make the draw result more likely to a circle.

.
The arm value set on the mDraw page must be the same length of the physical arm A and ARM B, once you change the physical length of arm B, need measure it again and fill in mDraw software again.
