Refer to picture....

Recommended Posts

Hi all,

Refer to the picture, its not suppose to be like that, is suppose to be a rectangular part. But any idea why the left and right sides happened to be like that? I check all motors are tight in their place. Is it because of belt slipping?

Thank you in advance.

Hi Daid,

I did like u said, at first it works. But now it happened again, even worst. I'm suspected that maybe my belt misaligned, that makes the nozzle head hard to move, and stuck a bit on its journey, that lead to that situation. I will check my belt alignment. Other than that, do u hv any idea? I already tighten all the axes pulleys. Many thanks in advance

Could be under powered steppers, but this seems more likely a pulley, likely one of the ones physically on the stepper motor, not one of the axis pulleys. Those grub screws kinda split the torque, while the the one on the motor shaft is all by it's lonesome. Double check it. Then you should make sure your axis are parallel by loosening the pulleys on the axis and squaring up the print head spanners with the axis. Then lubricate the axis and spanners with a sewing machine oil, or similar substitute. That should make printhead movement much easier, and hopefully mean you won't have to adjust the stepper pots, because that can be dicey...

Hi MSURunner,

Yeh u right. 1 of my pulley attached to the motor was loose, so even the motor moves, but the nozzle head didn't move. I already tighten it and lubricated all the rods, and now it works good again. Thanks :mrgreen:
