X axis incorrect after pausing print

[jb011a9840 3]

Hi folks,

I’ve been seeing some issues with my Ultimaker 3 ext when pausing a print.

When pausing the print from the front control panel the print head parks at the front left with a crunching noise and when the print is resumed the X axis now appears to have an offset of about 5mm (see photo 1)

The print was aborted and a new print started, this time everything looked OK but at some point, during the process the X axis decided to offset again be 5 mm (the printer was not paused during this print) (see photo 2)

This time the printer was powered down and restarted, the 3rd attempt at printing the part was a success.

The material being used is ABS with HIPS support, firmware 3.7.7.20170627

I have seen another random instance of this in the past (photo 3)

Has anyone else experienced this issue?

Did you pause with a cura gcode or a s3d gcode?

I ask because that sounds is the head trying to go beyond the limit when the x/y offset is set by a gcode. If you use s3d you need to activate the gcode offset

For the other issue. That I don’t know
