I have a problem with the 3d printing or modeling (Rhino + Makerbot )

[prangsoa]

Hello everyone.

I have started to learn how to use the 3d printer recentely and now I have a problem with my file.

I have made this file with Rhino 5.0 mac and Makerbot Raplicator 2 is used for the printing.

Problem is that 'back part' printed in the right place in the beginning. However, it started to print in the strange place after 2 hours and even another file is crashed and I could not send file from computer to machine.

Does anyone can solve the problem of my file? My school workshop tutors said that probably it is my file's problem but they could not find the problem.

Thank you and I will approciate if anyone can determine the problem.

Your printer has lost track of where the printhead is. This is most likely due to some mechanical problem with the printer.

Agreed, have you checked belt tightness ?

Also, do you have irregular feed from the extruder ?
