thanks for tue quick reply :) yes it must have been handled quite roughly as the end of the x axis (not the end with the board but the one where there is only the stepper motor is) is dented or bent which must have taken quite a bit of force since this is such a rigid part. luckily everything is fully functional so i dont really mind.
i also have now found the excenter screws and readjusted the alignment of the bearings. i am happy to say that my axidraw now works as intended and is very very precise without any unwanted moving parts! thanks again, really happy, very nice machine :) keep it up guys, greetings from austria :)
