[physicsrules 0]

Hi everyone. I’m having some problems calibrating the ultimaker2 printer, and, in one of my tries, this happen. Has anyone had the same problem?

Hi, thanks for your reply. I’m using version 15.02.1.

Ok, download cura 15.04.03 here and install the firmware.

Did you change anything?

Is it better with the latest firmware?

Hi. I already updated Cura and the firware of ultimaker2, but I’m still having problems. I did a new calibration but when it was starting printing, the buildplace went up and then went down two or three centimeters.

Your Z motor is moving double speed.  something is wrong with the PCB that controls it.  I would try a factory reset because that will reset the "steps/mm" setting.  It's also possible that the stepper chip (the servo controller chip) it is set to 8 microsteps instead of 16.  That would also make it move double speed.

If none of these things slow down the Z then you should contact support.ultimaker.com and point them to that video you showed and tell them gr5 thinks the Z is moving at 2X speed and distance  for some reason.

Oh - you could move the Z say 10mm and see if it actually moves 20mm.  You can do this many ways - tinkergnome's marlin lets you do that I think but the easiest way would be with pronterface/printrun which is a free, easy to use - it has a nice gui - you hook your computer to the um2 with the standard usb cable and tell it to move 10mm in Z:
