skewed print

[kopairnik]

Some initial questions:

Do you have any binding or friction on the Y-Axis? Can you confirm that the printer moves along the y-axis freely (in both directions) when not printing anything?

If a printer can not "retract" to it's original start location because of some bind/friction it will exhibit this behavior.

yes it does move freely, the belt is tight(as much as I could tight it ) and it does not skip a tooth when it moves.

The belt is not required to be extremely tight. As a matter of fact, it just needs to be taught. A belt that is too tight will increase the amount of torque required for the motors to move the head.

Skipping teeth would likely not be an issue (especially if the belt is set to the correct tension). It comes down to the fact that the motors can't spin because they can not output enough torque. A belt that is too tight may exhibit this behavior.

Is there any information you can reference for the belt tension of your specific printer?

the belt is not overly tightened, I just made sure that it wouldn't skip while the motor is turning and unfortunately there was no required belt tension provided with the manual.
