alignment issue replacing x axis motor

Recommended Posts

Posted · alignment issue replacing x axis motor

so my x axis motor failed an ive got a replacement from robokits in new zealand n(its the same stepper motor ultimaker uses.

when i installed the motor i noticed the belt doesnt align properly, anyone know why that is? should i just put some washers on the mounting bolts to try and bring the motor into alignment?

i made sure that the gear on the rod is pushed all the way to the bearing and it still wont align properly.

Rotating/inverting the pulley of the motor should fix that.

i did that, and now it is more aligned, but when i tighten everything up and slide the hot end back and forth, the belt sort of wobbles like the pulley is egg shaped or something, it rotates fairly smoothly, but you can still feel a bit of tugging as it tightens and loosens with each rotation. any thoughts?

If was like that when you used it it might have stretch and loose it's original size. The only fix I know (without mods) it's a new belt.

Did you try to invert also the pulley on the shaft btw?

i only inverted the pulley on the motor. ive tried moving the pulley back and forth along the motor shaft a little bit to try and align it better but it still happens. ive tried loosening the pulley on the x axis shaft to help align it and it hasnt helped. i wasnt having this problem before i replaced the motor either.

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
