I have made a custom 3d printer with ramps electronics. I have printed benchy(ship) well, but when i try to print any thing with tooth(spiral vase), gears(bearing), or circle(rocket), Y-axis skip steps in a regular rate giving 70:60 degrees skew along the printin the y-direction, but each layer is perfect, this happen when printing gear bearing.
I have checked y-axis ball bearing, motor, tension belt and i have replace my 6mm glass with 1mm without any differnece in shift.
I have once make it work, but I don't why or how(I have lowed speed to 50 and did some random things).
I have printed from pronterface and when I pause it then home-Y, the skipping in y in corrected.
I drive my x/y axis with no microsteeping and the skipping was much larger.
I only use slic3r for G-code generation.
What is the cause for that skipping?
If there is more than one possiblity, how could I check them seperately?
*I have changed my Y axis motor with no change.
*I have swaped x&y connections with no change still Y skips.
*I have lowered jerk and max speed and it prints gear bearing well and it is spinning, but when I tried to print spiral vase Y motor skipped.
